Reduction of laparoscopic-induced hypothermia, postoperative pain and recovery room length of stay by pre-conditioning gas with the Insuflow device: a prospective randomized controlled multi-center study. (1/754)

OBJECTIVE: To assess the efficacy and safety of Insuflow (Georgia BioMedical, Inc.) filter heater hydrator device in reducing the incidence, severity and extent of hypothermia, length of recovery room stay and postoperative pain at the time of laparoscopy. DESIGN: Prospective, randomized, blinded, controlled multi-center study. Patients underwent gynecologic procedures via laparoscopy; surgeons, anesthesiologists and recovery room personnel assessed the results. SETTING: Seven North American institutions. PATIENTS: Seventy-two women for safety evaluation and efficacy studies. INTERVENTIONS: Intraoperative pre-conditioning of laparoscopic gas with the Insuflow device (treatment) or standard raw gas (control) during laparoscopic surgery and postoperatively. MAIN OUTCOME MEASURES: Incidence, severity and extent of hypothermia, postoperative pain perception and length of recovery room stay. RESULTS: The Insuflow group had significantly less intraoperative hypothermia, reduced length of recovery room stay and reduced postoperative pain. Pre-conditioning of laparoscopic gas by filtering heating and hydrating was well tolerated with no adverse effects. The safety profile of the Insuflow pre-conditioned gas showed significant benefits compared to currently used raw gas. CONCLUSIONS: Pre-conditioning laparoscopic gas by filtering heating and hydrating with the Insuflow device was significantly more effective than the currently used standard raw gas and was safe in reducing or eliminating laparoscopic-induced hypothermia, shortening recovery room length of stay and reducing postoperative pain.  (+info)

The effect of graded postischemic spinal cord hypothermia on neurological outcome and histopathology after transient spinal ischemia in rat. (2/754)

BACKGROUND: Previous data have shown that postischemic brain hypothermia is protective. The authors evaluated the effect of postischemic spinal hypothermia on neurologic function and spinal histopathologic indices after aortic occlusion in the rat. METHODS: Spinal ischemia was induced by aortic occlusion lasting 10 min. After ischemia, spinal hypothermia was induced using a subcutaneous heat exchanger. Three studies were conducted. In the first study, the intrathecal temperature was decreased to 34, 30, or 27 degrees C for 2 h beginning with initial reperfusion. In the second study, hypothermia (target intrathecal temperature 27 degrees C) was initiated with reflow and maintained for 15 or 120 min. In the third study, the intrathecal temperature was decreased to 27 degrees C for 2 h starting 5, 60, or 120 min after normothermic reperfusion. Animals survived for 2 or 3 days, at which time they were examined and perfusion fixed with 4% paraformaldehyde. RESULTS: Normothermic ischemia followed by normothermic reflow resulted in spastic paraplegia and spinal neuronal degeneration. Immediate postischemic hypothermia (27 degrees C for 2 h) resulted in decreasing motor dysfunction. Incomplete protection was noted at 34 degrees C. Fifteen minutes of immediate cooling (27 degrees C) also provided significant protection. Delay of onset of post-reflow hypothermia (27 degrees C) by 5 min or more failed to provide protection. Histopathologic analysis revealed temperature-dependent suppression of spinal neurodegeneration, with no effect of delayed cooling. CONCLUSIONS: These findings indicate that the immediate period of reperfusion (0-15 min) represents a critical period that ultimately defines the degree of spinal neuronal degeneration. Hypothermia, when initiated during this period, showed significant protection, with the highest efficacy observed at 27 degrees C.  (+info)

Perinatal risk and severity of illness in newborns at 6 neonatal intensive care units. (3/754)

OBJECTIVES: This multisite study sought to identify (1) any differences in admission risk (defined by gestational age and illness severity) among neonatal intensive care units (NICUs) and (2) obstetric antecedents of newborn illness severity. METHODS: Data on 1476 babies born at a gestational age of less than 32 weeks in 6 perinatal centers were abstracted prospectively. Newborn illness severity was measured with the Score for Neonatal Acute Physiology. Regression models were constructed to predict scores as a function of perinatal risk factors. RESULTS: The sites differed by several obstetric case-mix characteristics. Of these, only gestational age, small for gestational age. White race, and severe congenital anomalies were associated with higher scores. Antenatal corticosteroids, low Apgar scores, and neonatal hypothermia also affected illness severity. At 2 sites, higher mean severity could not be explained by case mix. CONCLUSIONS: Obstetric events and perinatal practices affect newborn illness severity. These risk factors differ among perinatal centers and are associated with elevated illness severity at some sites. Outcomes of NICU care may be affected by antecedent events and perinatal practices.  (+info)

Hypothermic stress leads to activation of Ras-Erk signaling. (4/754)

The small GTPase Ras is converted to the active, GTP-bound state during exposure of vertebrate cells to hypothermic stress. This activation occurs more rapidly than can be accounted for by spontaneous nucleotide exchange. Ras-guanyl nucleotide exchange factors and Ras GTPase-activating proteins have significant activity at 0 degrees C in vitro, leading to the hypothesis that normal Ras regulators influence the relative amounts of Ras-GTP and Ras-GDP at low temperatures in vivo. When hypothermic cells are warmed to 37 degrees C, the Raf-Mek-Erk protein kinase cascade is activated. After prolonged hypothermic stress, followed by warming to physiologic temperature, cultured fibroblasts assume a rounded morphology, detach from the substratum, and die. All of these biologic responses are attenuated by pharmacologic inhibition of Mek. Previously, it had been found that low temperature blocks acute growth factor signaling to Erk. In the present study, we found that this block occurs at the level of Raf activation. Temperature regulation of Ras signaling could help animal cells respond appropriately to hypothermic stress, and Ras-Erk signaling can be manipulated to improve the survival of cells in cold storage.  (+info)

Hypothermia: a complication of diabetic ketoacidosis. (5/754)

During 1969-77, 20 episodes of severe hypothermia occurred in 19 diabetic patients in Nottingham. Thirteen were associated with ketotic hyperosmolar coma, two with lactic acidosis, and one with hypoglycaemia, while in four there was no loss of diabetic control. Ketoacidosis accounted for 11.8% of all admissions for severe accidental hypothermia and was a commoner cause than hypothyroidism (8%). Patients with ketoacidosis were younger and developed hypothermia as often during the summer as during the winter. The metabolic disturbance was characteristic, with severe acidosis (mean pH 7.04), a high blood glucose concentration (mean 56.6 mmol/l; 1020 mg/100 ml), and high plasma osmolality (mean 379.7 mmol (mosmol)/kg). Eight of the 13 episodes proved fatal. Hypothermia may aggravate ketoacidosis and complicate treatment and should be sought in all patients with severe diabetic coma.  (+info)

F 11356, a novel 5-hydroxytryptamine (5-HT) derivative with potent, selective, and unique high intrinsic activity at 5-HT1B/1D receptors in models relevant to migraine. (6/754)

F 11356 (4-[4-[2-(2-aminoethyl)-1H-indol-5-yloxyl]acetyl]piperazinyl-1-yl] ben zonitrile) was designed to take advantage of the superior potency and efficacy characteristics of 5-hydroxytryptamine (5-HT) compared with tryptamine at 5-HT1B/1D receptors. F 11356 has subnanomolar affinity for cloned human and nonhuman 5-HT1B and 5-HT1D receptors, and its affinity for 5-HT1A and other 5-HT receptors, including the 5-ht1F subtype, is 50-fold lower and micromolar, respectively. In C6 cells expressing human 5-HT1B or human 5-HT1D receptors, F 11356 was the most potent compound in inhibiting forskolin-induced cyclic AMP formation (pD2 = 8.9 and 9.6), and in contrast to tryptamine and derivatives, it produced maximal enhancement of [35S]guanosine-5'-O-(3-thio)triphosphate-specific binding equivalent to 5-HT. F 11356 was equipotent to 5-HT (pD2 = 7.1 versus 7.2) and more potent than tryptamine derivatives in contracting rabbit isolated saphenous vein. In isolated guinea pig trigeminal ganglion neurons, F 11356 was more potent (pD2 = 7.3 versus 6.7) and induced greater increases in outward hyperpolarizing Ca2+-dependent K+ current than sumatriptan. In anesthetized pigs, F 11356 elicited highly cranioselective, more potent (from 0.16 microgram/kg i.v.) and greater carotid vasoconstriction than tryptamine derivatives. Decreases in carotid blood flow were observed in conscious dogs from 0.63 mg/kg oral F 11356 in the absence of changes in heart rate or behavior. Oral activity was confirmed when hypothermic responses were elicited in guinea pigs (ED50 = 1.6 mg/kg), suggesting that F 11356 also accesses the brain. F 11356 thus is a selective, high-potency agonist at 5-HT1B/1D receptors, which distinguishes itself from tryptamine and derivatives in exerting high intrinsic activity at these receptors in vascular and neuronal models relevant to migraine.  (+info)

Humanization of mouse 5-hydroxytryptamine1B receptor gene by homologous recombination: in vitro and in vivo characterization. (7/754)

We replaced the coding region of the murine 5-hydroxytryptamine (5-HT)1B receptor by the human 5-HT1B receptor using homologous recombination in embryonic stem cells and generated and characterized homozygous transgenic mice that express only the human (h) 5-HT1B receptor. The distribution patterns of h5-HT1B and murine (m) 5-HT1B receptor mRNA and binding sites in brain sections of transgenic and wild-type mice were identical as measured by in situ hybridization histochemistry and radioligand receptor autoradiography. When measured in parallel under identical conditions, the h5-HT1B receptor expressed in mouse brain had the same pharmacological characteristics as that in human brain. Stimulation by 5-HT1B agonists of [35S]guanosine-5'-O-(3-thio)triphosphate binding in brain sections demonstrated the functional coupling of the h5-HT1B receptor to G proteins in mouse brain. In tissue slices from various brain regions, electrically stimulated [3H]5-HT release was not modified by 5-HT1B agonists in tissue from either transgenic and wild-type mice; a 5-HT1B antagonist enhanced electrically stimulated [3H]5-HT release in wild-type mouse brain, but was ineffective in the transgenics. The centrally active 5-HT1A/5-HT1B agonist RU24969 induced hypothermia but did not increase locomotor activity in the transgenic mice. The ineffectiveness of RU24969 in the transgenic mice could be due to the lower affinity of the compound for the h5-HT1B receptor compared with the m5-HT1B receptor. The present study demonstrates a complete replacement of the mouse receptor by its human receptor homolog and a functional coupling to G proteins. However, modulation of [3H]5-HT release could not be shown. Furthermore, behavioral effects were not clearly observed, which may be due to a lack of appropriate tools.  (+info)

Acute systemic reaction and lung alterations induced by an antiplatelet integrin gpIIb/IIIa antibody in mice. (8/754)

Shock is frequently accompanied by thrombocytopenia. To investigate the pathogenic role of platelets in shock, we examined the in vivo effects of monoclonal antibodies (MoAbs) against mouse platelet membrane proteins. Injection of the platelet-specific MoAb MWReg30 to the fibrinogen receptor (gpIIb/IIIa) rendered mice severely hypothermic within minutes. Isotype-matched control antibodies, even if they also recognized platelet surface antigens, did not induce comparable signs. MWReg30 induced early signs of acute lung injury with increased cellularity in the lung interstitium and rapid engorgement of alveolar septal vessels. Despite this in vivo activity, MWReg30 inhibited rather than stimulated platelet aggregation in vitro. MWReg30-binding to platelets led to phosphorylation of gpIIIa, but did not induce morphological signs of platelet activation. The MWReg30-induced reaction was abolished after treatment with MoAbs 2.4G2 to FcgammaRII/III and was absent in FcgammaRIII-deficient mice, clearly demonstrating the requirement for FcgammaRIII on involved leukocytes. Simultaneous administration of tumor necrosis factor exacerbated, whereas a tolerizing regimen of tumor necrosis factor or bacterial lipopolysaccharide completely prevented the reaction. These data suggest that platelet surface-deposited MWReg30-immune complexes lead to an acute Fc-mediated reaction with pulmonary congestion and life-threatening potential that could serve as an in vivo model of acute lung injury.  (+info)

Hypothermia is an important cause of preventable deaths in the United States, especially among persons who abuse alcohol (3). Ethanol causes vasodilation, which produces a brief warming sensation that interferes with peripheral vasoconstriction, the physiological defense against cold, while also inducing hypoglycemia. Alcohol consumption in cold surroundings is a dangerous practice. Unattended children and persons aged ,65 years also are at greater risk for hypothermia (3). Hypothermia during cold weather is the result of decreased heat production, increased heat loss, or impaired thermoregulation (1). Older persons, who have a decreased basal metabolic rate, might be at further risk for hypothermia because of impaired physical exertion, which produces heat to keep the body warm (4). Inactivity limits heat production through physical exertion, but overexertion can increase evaporation from the respiratory tract and cause fatigue. Shivering also can cause enough lactate generation eventually to ...
Inadvertent perioperative hypothermia is a phenomenon that can occur as a result of the suppression of the central mechanisms of temperature regulation due to anaesthesia, and of prolonged exposure of large surfaces of skin to cold temperatures in operating rooms. Inadvertent perioperative hypothermia has been associated with clinical complications such as surgical site infection and wound-healing delay, increased bleeding or cardiovascular events. One of the most frequently used techniques to prevent inadvertent perioperative hypothermia is active body surface warming systems (ABSW), which generate heat mechanically (heating of air, water or gels) that is transferred to the patient via skin contact. To assess the effectiveness of pre- or intraoperative active body surface warming systems (ABSW), or both, to prevent perioperative complications from unintended hypothermia during surgery in adults. We searched the Cochrane Central Register of Controlled Trials (CENTRAL; Issue 9, 2015); MEDLINE ...
The valveless trocar system is a novel insufflator that circulates carbon dioxide in the abdominal cavity. Herein, we report an infant with severe hypothermia due to use of this insufflator. An 83-day-old infant (body weight 3862 g) with gastroesophageal reflux underwent laparoscopic Nissen fundoplication.
Severe hypothermia, i.e. a body temperature of less than 24 degrees Celsius, is often deadly. Affected people are unconscious, suffer from respiratory and cardiac arrest and do not show any signs of life. On 6 April 2017 in Poland, a woman was found being unresponsive, without a pulse and with a body temperature of 20.6 degrees Celsius. In addition to the standard resuscitation measures, the rescuers used the EASY PULSE for automatic cardiac massage. Luckily, the woman survived and regained consciousness after two days..

Purpose: To measure core temperature (T core) in open-water (OW) swimmers during a 25-km competition and identify the predictors of T core drop and hypothermia-related dropouts. Methods: Twenty-four national- and international-level OW swimmers participated in the study. Participants completed a personal questionnaire and a body fat/muscle mass assessment before the race. The average speed was calculated on each lap over a 2500-m course. T core was continuously recorded via an ingestible temperature sensor (e-Celsius, BodyCap). Hypothermia-related dropouts (H group) were compared with finishers (nH group). Results: Average prerace T core was 37.5°C (0.3°C) (N = 21). 7 participants dropped out due to hypothermia (H, n = 7) with a mean T core at dropout of 35.3°C (1.5°C). Multiple logistic regression analysis found that body fat percentage and initial T core were associated with hypothermia (G 2 = 17.26, P , .001). Early T core drop ≤37.1°C at 2500 m was associated with a greater rate of ...
Hypothermia happens when someones body temperature drops below 35°C (95°F). Normal body temperature is around 37°C (98. 6°F). Hypothermia can become life-threatening quickly, so its important to treat someone with hypothermia straight away. Severe hypothermia, when the body temperature falls below 30°C (86°F), is often fatal. When your body temperature drops,your heart,nervous system and other organs cant work normally. Left untreated, hypothermia can eventually lead to complete failure of your heart and respiratory system and to death. Hypothermia is usually caused by being in a cold environment for a long time. This could be from staying outdoors in cold conditions, falling into cold water, or from living in a poorly heated house. Elderly people, babies, homeless people and anyone who is thin and frail or not able to move around easily are particularly vulnerable. Shivering is likely the first thing youll notice as the temperature starts to drop because its your bodys automatic defense
Accidental hypothermia is defined as an unintentional decrease in core body temperature to below 35°C. Hypothermia causes hundreds of deaths in the United States annually. Victims of accidental hypothermia present year-round and in all climates with a potentially confusing array of signs and symptoms, but increasing severity of hypothermia produces a predictable pattern of systemic organ dysfunction and associated clinical manifestations. The management of hypothermic patients differs in several important respects from that of euthermic patients, so advance knowledge about hypothermia is prerequisite to optimal management. The paucity of randomized clinical trials with hypothermic patients precludes creation of evidence-based treatment guidelines, but a clinically sound management strategy, tailored to individual patient characteristics and institutional expertise and resources, can nonetheless be gleaned from the literature. This article reviews the epidemiology, pathophysiology, clinical ...
Background: Accidental hypothermia increases mortality and morbidity in trauma patients. Various methods for insulating and wrapping hypothermic patients are used worldwide. The aim of this study was to compare the thermal insulating effects and comfort of bubble wrap, ambulance blankets / quilts, and Hiblers method, a lowcost method combining a plastic outer layer with an insulating layer. Methods: Eight volunteers were dressed in moistened clothing, exposed to a cold and windy environment then wrapped using one of the three different insulation methods in random order on three different days. They were rested quietly on their back for 60 minutes in a cold climatic chamber. Skin temperature, rectal temperature, oxygen consumption were measured, and metabolic heat production was calculated. A questionnaire was used for a subjective evaluation of comfort, thermal sensation, and shivering. Results: Skin temperature was significantly higher 15 minutes after wrapping using Hiblers method compared ...
You can survive in 78deg water for a very long time, and most of the people on board swam to the shore quite quickly, and the rescuers came on the scene promptly.. Some people can survive in 78F water for a prolonged period of time, while other people in poor physical condition and/or having just suffered physical trauma often may not. The SST (Sea Surface Temperature) of 77-78°F was low enough to eventually bring about a lowering of body core temperature to the range for mild hypothermia at 90-95°F, moderate hypothermia at 82-90°F, or even severe hypothermia at 68-82°F. Trauma suffered when the aircraft ditched in the sea could very well have contributed to a more rapid onset of hypothermia as the heart rate, blood pressure, and respiratory rated dropped. Under such conditions, especially in the presence of aggravated hypoglycemia or hyperglycemia, you can see heart problems become a risk for fatality.. It is untrue to say, most of the people on board swam to the shore quite quickly. ...

An Hypothermia is defined as a decrease in core temperature below 35 degrees C. The well-described deleterious effects of accidental hypothermia on outcome in multiple-trauma patients contrast the beneficial effect of controlled hypothermia on organ function during ischemia in elective surgery. Experimental studies have shown that induced hypothermia during hemorrhagic shock might have beneficial effects on outcome. The beneficial effects of induced hypothermia appear to be partly mediated by the prolongation of the golden hour with prevention of hypoxic organ dysfunction. However, hypothermia also has been thought to have an impact on the immunologic response after trauma and elective surgery. Induction of hypothermia seems to decrease the release of pro-inflammatory cytokines believed to influence distant organ damage positively, and is mediated by the interaction of polymorphonuclear leucocytes (PMNL) and capillary endothelial cells. Nevertheless, the incidence of posttraumatic infectious ...
Bacterial endotoxin produces sepsis associated with alterations in body temperature (fever or hypothermia). The intraperitoneal administration of bacterial endotoxin, lipopolysaccharide (LPS; 50 μg/mouse) led to a decrease in colonic temperature starting 1 hr after the injection. The hypothermic effect was accompanied by a significant increase in hypothalamic leukotriene B4 (LTB4) and prostaglandin E2 (PGE2) levels. 5-lipoxygenase inhibitor, zileuton (200 and 400 Mg/kg. po) administered 30 min before LPS challenge significantly prevented hypothermia. However, non-selective cyclooxygenase inhibitor, indomethacin (10, 20 mg/kg, po) did not reverse the hypothermic response. Further, pretreatment of mice with zileuton prevented LPS-stimulated increase in hypothalamic LTB4 levels and caused a relatively small increase in PGEz levels. Indomethacin had no effect on LTB4 levels but it reduced PGE2 levels. These results suggest a possible involvement of leukotrienes in LPS-induced hypothermia and the ...
The anaesthetic records of 1525 dogs were examined to determine the prevalence of postanaesthetic hypothermia, its clinical predictors and consequences. Temperature was recorded throughout the anaesthesia. At the end of the procedure, details coded in were: hyperthermia (,39.50°C), normothermia (38.50°C-39.50°C), slight (38.49°C-36.50°C), moderate (36.49°C-34.00°C) and severe hypothermia (,34.00°C). Statistical analysis consisted of multiple regression to identify the factors that are associated with the temperature at the end of the procedure. Before premedication, the temperature was 38.7 ± 0.6°C (mean ± sd). At 60, 120 and 180 minutes from induction, the temperature was 36.7 ± 1.3°C, 36.1 ± 1.4°C and 35.8 ± 1.5°C, respectively. The prevalence of hypothermia was: slight, 51.5 per cent (95 per cent CI 49.0 to 54.0 per cent); moderate, 29.3 per cent (27.1-31.7 per cent) and severe: 2.8% (2.0-3.7%). The variables that associated with a decrease in the temperature recorded at the ...

Our experiments addressed the hypothesis that CART peptides effects on energy balance cannot be characterized as simply catabolic in nature. CART peptide was applied to the fourth ventricle (hindbrain directed), the third ventricle (hypothalamus directed), and directly to the NTS parenchyma and its effects on energetic (Tc and activity), cardiovascular (HR), food intake, body weight, and plasma glucose parameters were measured. Our data show that CNS delivery of CART results in a hypothermia. We discuss the hypothermic effect first, the GLP-1R mediation of this response next, and then review the other effects observed.. These are the first data to show that hindbrain CART55-102 delivery induced a pronounced and long-lasting hypothermic response (a 1.5°C and 1.6°C decrease in Tc for the 1.0 and 2.0 μg doses relative to vehicle treatment; ,6 h duration). Injections of CART into the forebrain ventricle (providing access of drug to forebrain and hindbrain sites attributable to the caudal flow of ...
WG patients were significantly warmer on arrival to the operating room (OR) and were 60% less likely to develop PH (p , 0.001). Preoperative forced air warmer use both reduced the risk of PH at time 0 intraoperatively and significantly reduced the risk of any PH intraoperatively (p , 0.001). All patients, regardless of group, experienced a drop in core temperature until a nadir occurred at 30 minutes intraoperatively for the WG and 45 minutes for the CG. At every time interval, from preoperatively to 120 minutes intraoperatively, CG patients were between 2 and 3 times more likely to experience PH (p , 0.001). All patients were warm on arrival to the postanesthesia care unit regardless of patient group. ...
Background Both accidental and perioperative hypothermia are common in the elderly. The elderly are at risk because their responses to hypothermia may be delayed or less efficient than in those of younger subjects. For example, the vasoconstriction threshold during isoflurane anesthesia is [nearly equal] 1 degree Celsius less in elderly than younger patients. However, the extent to which other cold defenses are impaired in the elderly remains unclear, especially in those older than 80 yr. Operations suitable for spinal anesthesia provided an opportunity to quantify shivering thresholds in patients of varying ages. Accordingly, the hypothesis that the shivering threshold is reduced as a function of age during spinal anesthesia was tested ...

A British woman has made a full recovery after suffering a six-hour cardiac arrest caused by severe hypothermia -- a condition that doctors say also saved her life.
The data presented here demonstrate that IGF-1R regulates the hypothermic response to CR, and identify this receptor as one of the mediators of the integration of nutrient and temperature homeostasis.. The involvement of IGF-1R was demonstrated by a combination of its pharmacological inhibition or activation and by the data obtained with three different and complementary animal models: UBIKOR, Igf1r+/−, and inIGF1RKO mice representing ubiquitous adult deletion, reduced expression, or prosencephalic neuron-specific ablation of IGF-1R, respectively. Pharmacology and the genetic deletion of IGF-1R in UBIKOR and inIGF1RKO mice were obtained in adult animals, eliminating the possibility that the phenotype observed could be the result of developmental defects. The possibility that the effects observed could be due to differences in body weight or body composition was also ruled out. Using these experimental approaches, we found that IGF-1R regulated Tb differently in males and females, depending on ...
Other factors both external and internal can speed the bodys willingness to sacrifice heat. Water conducts heat away from the body 25 times faster than air. Underlying medical conditions can also affect the bodys compensatory function. Any medical condition that hinders heart function, metabolic function, vasoconstriction or shivering will affect the patients ability to maintain core warmth. Being elderly, young, sick, drunk, male or high all make you more likely to succumb to hypothermia.. So now that we know how the body looses heat and what things might accelerate it, lets take a walk through a typical plummeting core temperature. The following numbers represent degrees Fahrenheit.. 103.0-96.4 The normal core temperature range. Remember that body heat fluctuates quite a bit during a typical day. Exercise might raise core temperature from a standard 98.6 to temperatures as high as 103.0. Body temperature may also fall as low as 96.4 at rest. Temperatures in our limbs tend to stay 1-2 degrees ...

Accidental hypothermia (AH) is defined as an involuntary decrease in core body temperature to | 35 °C. The management of AH has been progressing over the last few decades, and numerous techniques for rewarming have been validated. However, little is known about the association between rewarming rate (RR) and mortality in patients with AH. This was a multicentre chart review study of patients with AH visiting the emergency department of 12 institutions in Japan from April 2011 to March 2016 (Japanese accidental hypothermia network registry, J-Point registry). We retrospectively registered patients using the International Classification of Diseases, Tenth Revision code T68: hypothermia. We excluded patients whose body temperatures were unknown or ≥ 35 °C, who could not be rewarmed, whose rewarmed temperature or rewarming time was unknown, those aged | 18 years, or who or whose family members had refused to join the registry. RR was calculated based on the body temperature on arrival at the hospital,
Objective(s): The aim of this study wasto investigate the effects of mild hypothermia therapy on oxidative stress injury of rabbit brain tissue after cardiopulmonary resuscitation (CPR). Materials and Methods: Rabbit models of cardiac arrest were established. After the restoration of spontaneous circulation, 50 rabbits were randomly divided into normothermia and hypothermia groups. The following five time points were selected: before CPR, immediately after CPR, 2 hr after CPR (hypothermia group reached the target temperature), 14 hr after CPR (hypothermia group before rewarming), and 24 hr after CPR (hypothermia group recovered to normal temperature). Glutathione (GSH) concentrations in both the blood and cerebrospinal fluid of the normothermia and hypothermia groups were measured. Results:At 2, 14, and 24 hr after CPR, the GSH concentrations in both the blood and cerebrospinal fluid were significantly higher in the hypothermia group than in the nomorthermia group. Conclusion:Mild hypothermia therapy
When you body temperature falls below 35ºC (95ºF) then this is considered to be hypothermia. It can be classified as mild or severe. Mild hypothermia is a temperature between 35ºC (95ºF) and 32ºC (89.6ºF). Severe hypothermia is a body temperature below 32ºC (89.6ºF).However, the first signs and symptoms of hypothermia becomes evident once the body temperature drops below 36.5ºC (97.7ºF).. The body temperature is maintained by several factors that are regulated by a part of the brain known as the hypothalamus. If the body temperature rises too high, then the hypothalamus initiates cooling mechisms. Blood vessels on the skin surface widen so that heat can be passed out from the blood into the environment. Sweat is released on the skin surface to help cool down the body.. When the body temperature drops too low then the hypothalamus has to find ways too warm the body. This is done by increasing metabolic activity so that more heat is generated by the body. For example, shivering is an ...
Background and Purpose. Studies have shown that inter-ischemia hypothermia is able to reduce the size of myocardial infarctions and improve their clinical outcomes. The present study determined whether inter-ischemia hypothermia induced by pharmacological approach induced stronger neuroprotection in ischemic brains. Methods. Adult male Sprague-Dawley rats were studied in 4 groups: (1) sham; (2) stroke; (3) stroke treated with pharmacological hypothermia before reperfusion (inter-ischemia hypothermia); and (4) stroke treated with pharmacological hypothermia after reperfusion is initiated (inter-reperfusion hypothermia). The combination of chlorpromazine and promethazine with dihydrocapsaicin was used to induce hypothermia. To compare the neuroprotective effects of drug-induced hypothermia between the groups, brain damage was evaluated using infarct volume and neurological deficits. In addition, mRNA expressions of NADPH oxidase subunits and glucose transporter subtypes were determined by real-time PCR.

We showed in a previous experimental study that moderate hypothermia during CPB increases IL10 blood concentrations and blunts TNFα production (2). We demonstrate here that systemic moderate hypothermia leads to increased gene expression and synthesis of IL10 in the myocardium after CPB and that this is related to myocardial protection. Despite the short observational period of 6 h, which did not allow us to extrapolate the outcome of the animals investigated, a substantial clinical benefit could be noticed, wherein the need for inotropic support to maintain stable hemodynamics was less in animals that were in moderate hypothermia during surgery. This cardioprotective effect of moderate hypothermia related to anti-inflammatory cytokine balance shown here could justify its use in clinical practice, especially in patients with severe preoperative heart failure in whom pro-inflammatory cytokine synthesis in the myocardium is thought to contribute to myocardial dysfunction (4).. The mechanisms by ...

Stroke remains a disease with a serious impact on quality of life but few effective treatments exist. There is an urgent need to develop and/or improve neuroprotective strategies to combat this. Many drugs proven to be neuroprotective in experimental models fail to improve patient outcome in a clinical setting. An emerging treatment, therapeutic hypothermia (TH), is a promising neuroprotective therapy in stroke management. Several studies with TH in experimental models and small clinical trials have shown beneficial effects. Despite this, implementation into the clinical setting is still lacking due to methodological considerations as well as hypothermia-related complications. This paper discusses the possible opportunities and limitations of the use of TH in animal models and the translation into the clinic.
Accidental hypothermia has a high mortality and is associated with cardiac arrhythmias. To determine the incidence of arrhythmias and their importance 22 patients with accidental hypothermia (core temperature less than 35 degrees C) were studied by 12 lead electrocardiography and continuous recording of cardiac rhythm. Although 14 of the patients died (64%), only six died while hypothermic. Prolongation of the Q-T interval and the presence of J waves were related to the severity of the hypothermia. Supraventricular arrhythmias, including atrial fibrillation, were common (nine cases) and benign. Ventricular extrasystoles were also common (10 cases), but ventricular tachycardia or fibrillation did not occur during rewarming. In eight patients who died while being monitored the terminal rhythm was asystole. There was no correlation between the severity of hypothermia or the rate of rewarming and the clinical outcome. In the absence of malignant arrhythmias there is no indication for using ...
They suffered from profound acute hypothermia.To understand how this might have been prevented, we need to understand what happens as hypothermia develops. Chronic hypothermia is the lowering of the core temperature below 95 °F (35 °C) over a period of six hours or longer. This develops by simply not having enough clothing to maintain a thermal balance with the environment. The body uses vasoconstriction to reduce heat loss to the extremities by shutting down blood flow to them. The rescue of a chronic hypothermic individual requires the prevention of further heat loss. When the core temperature is above 90 °F (32 °C) virtually any method of handling the victim is fine. Heat may be added rapidly or slowly. The victim may engage in any activity they want. Just get them heat, shelter, food, hydration and rest.. Profound chronic hypothermia occurs when the core temperature is slowly lowered (six hours or more) to below 90 °F (32 °C). The vasoconstriction at this point will have caused a ...
Clinical efficacy of hypothermia in neonatal hypoxic-ischemic (HI) encephalopathy is limited, in part, by the delay in instituting hypothermia. In a piglet model of HI, half of the neurons in putamen already show ischemic cytopathology by 6 h of recovery. We tested the hypothesis that treatment with the SOD-catalase mimetic EUK-134 at 30 min of recovery provides additive neuronal protection with a clinically relevant delay of 4 h in the onset of whole body hypothermia. Anesthetized piglets were subjected to 40 min of hypoxia (10% inspired O2) followed by 7 min of airway occlusion and resuscitation with epinephrine and chest compressions. Body temperature was maintained at 38.5 °C in normothermic groups and at 34 °C in hypothermic groups from 4 h through 24 h of recovery. All groups were mechanically ventilated and sedated with continuous fentanyl and pancuronium infusion during the 4 -24 h period to reduce the stress of hypothermia and shivering. At 10 days of recovery, viable neurons ...
Victims of severe accidental hypothermia are prone to fluid extravasation but rarely develop lung edema. We hypothesize that combined hypothermia-induced increase in pulmonary vascular resistance (PVR) and a concomitant fall in cardiac output protect the lungs against edema development. Our aim was to explore in hypothermic- isolated blood-perfused rat lungs whether perfusion at constant pressure influences fluid filtration differently from perfusion at constant flow ...

Purpose of the study: Early out-of-hospital induction of mild hypothermia after cardiac arrest needs an easy to use and accurate core temperature monitoring, which might be achievable with tracheal temperature measurement. The aim of the study was to evaluate which tracheal temperature site (Ttra) reflects best pulmonary artery temperature (Tpa) during the induction of mild hypothermia.. Methods: Eight pigs (29 -38 kg) were anesthetized and intubated with a specially designed endotracheal tube with three temperature probes: Ttra1 was attached to the wall of the tube, 1 cm proximal to the cuff-balloon, without contact to the mucosa; Ttra2 and Ttra3 were placed on the cuff-balloon with tight contact to the mucosa, whereas Ttra3 was covered by a plastic tube to protect the mucosa. Core temperature was measured with a pulmonary artery catheter (Tpa). Pigs were cooled with a new surface cooling device (Emcoolspad®, Vienna, Austria). Data are presented as mean (±SD), and mean differences (95% ...
10 patients received hypothermia, while 9 were normothermic controls. It took an average of 3.5 hours to reach the target temperature of 32º C. In 9 out of 10 patients, the target was overshot, and the entire cooling and rewarming process lasted an average of 47.4 hours. There was a measurable, but non-statistically significant trend (P = 0.14) towards better clinical outcome in the hypothermic group: 50% of the hypothermic patients and 90% of the normothermic patients had bad outcomes. There was also a trend towards reduced infarct volume in the hypothermic cohort. Sinus bradycardia was the only complication to occur with a significantly higher frequency in the hypothermia group than in the control group. Researchers conclude that induced moderate hypothermia in acute ischemic stroke is both feasible and safe. A larger study of poststroke cooling is underway.. ...
Cardiac arrest occurs when the heart suddenly stops beating and blood flow to the body is halted. It can occur while people are in the hospital because of a medical condition or while people are out of the hospital as a result of an accident or other cause. Cardiac arrest is a serious event that is associated with high rates of death and long-term disability. When a person experiences cardiac arrest,insufficient amount of blood flow and oxygen can result in brain injury.. Therapeutic hypothermia is a therapy that involves a controlled lowering of the body temperature and then maintenance of this lower temperature for a period of time. Therapeutic hypothermia has been successfully used in adults who experience cardiac arrest to improve survival rates and health outcomes, and it has also been studied in newborn infants who have suffered from perinatal asphyxia. The purpose of this study is to evaluate the efficacy of therapeutic hypothermia at improving survival rates and reducing brain injury in ...

Dr. Shankaran is continuing to study the hypothermia therapy. In a study submitted for publication that involves the same two groups of babies, MRIs tend to be more favorable for the hypothermia group, she said. Her team is also looking at variations on how best to use hypothermia. For instance, they are studying whether more time - 120 hours instead of 72 - and a lower temperature - 32 degrees instead of 33.5 - might deliver better results.. Donna Ferriero, MD, the W.H. and Marie Wattis Distinguished Professor and chair of the department of pediatrics at the University of California, San Francisco, said it is not fully understood why hypothermia therapy helps prevent brain injury in babies.. We still dont know the true mechanism at work, she told Neurology Today. We think we are slowing the metabolism and thus ultimately preventing cell death.. Dr. Ferriero was part of a research team that investigated the use of Cool-Cap, a brain-cooling cap that works on the same principle as whole-body ...
Enteral Feeding during therapeutic hypothermia, 978-3-659-61988-5, The basic provision of nutrition in the critical care population has been associated with reduced length of stay and improved outcome. Often catabolic, these patients are at risk of malnutrition. Government bodies advise and expect those requiring mechanical ventilation during critical illness to be enterally fed wherever possible. Cardiac arrest victims treated with neuroprotective therapeutic hypothermia often encounter the postponement of enteral feed until normothermia is restored. This is due to a lack of research evidence surrounding the ability for a hypothermic patient to absorb feed formulas. This is the first known study that sought to identify what percentage of feed could be tolerated by cooled victims of cardiac arrest during three distinct phases of therapeutic hypothermia. This included 24 hours at target temperature (32-34°C), 24 hours rewarming to 36.5°C and 24 hours maintained at a core temperature below 37.5°C. A

Dogs and cats commonly lose heat when anesthetized. Maintaining body temperature within a narrow range is important for cardiac function, metabolism, normal enzyme activity, nerve conduction, and hemostasis. Several studies report that small patients, for example cats weighing less than 2 kg, are more likely to die than cats weighing between 2-6 kg and that senior patients and those undergoing long procedures also carry a higher perioperative risk.1-3 It has been suggested that these increased risks may be related to hypothermia. In cats, Redondo and colleagues correlated intraoperative hypothermia with mortality.4 The negative impact of hypothermia is greatly underestimated and its occurrence often goes undetected because intra-operative temperatures are not often monitored.. Thermal Balance. Homeothermy, a balance between heat loss and heat gain involves complex sensing mechanisms that drive the mechanisms controlling heat loss or gain in the correct direction. Heat gains can be obligatory or ...
Hypothermia is a condition characterized by a dangerously low body temperature. Its a medical emergency caused when the body loses heat faster than it produces. It occurs when the normal body temperature (98.6 For 37 C) drops below 95 F or 35 C. The drop in temperature can thus impact the normal functioning of vital organs such as the heart, nervous system etc.. If not treated in a timely manner, hypothermia may cause a complete failure of the heart and respiratory system, leading eventually to death. This condition happens due to exposure to cold weather or immersion in cold water. So, keeping yourself safe during the winter weather is key to avoiding this serious illness.. ...

Patients often regain consciousness 3 days or more after arrest. Physicians may be making premature predictions about which patients are not likely to survive following cardiac arrest - and even withdrawing care -- before the window in which comatose patients who have received therapeutic hypothermia are most likely to wake up, according to two new studies from the Perelman School of Medicine at the University of Pennsylvania. The research helps to better define the proper timeframe and manner in which doctors may be able to predict which patients will regain consciousness after the use of therapeutic hypothermia, which preserves brain and other organ function following cardiac arrest.. Patients treated with hypothermia often dont regain consciousness until three or more days after their cardiac arrest, according Penn research that will present today at the American Heart Associations annual Scientific Sessions (Abstract #10778. But in a separate Penn study published online this week in ...

Diagnosis. Low body temperature and history of exposure to cold are the common criteria for diagnosis. There are other ways your cats temperature can become below normal, so your veterinarian will carefully examine your cat to see if any of these other factors are contributing to the hypothermia.. Treatment. How intense the rewarming effort depends on your cats body temperature. For rectal temperatures slightly below normal (approximately 96° F to 100° F), drying your cat and covering him with blankets or warm towels is usually sufficient. For lower rectal temperatures, hot water bottles and similar external warming methods will be used as well. For severely hypothermic cats (rectal temperature below 90° F), warmed intravenous (IV) fluids, and even a warm water enema will also be used to bring your cats temperature back to normal. If there are any other factors contributing to the hypothermia, your veterinarian will address those as well.. ...

Dr Beat Walpoth is speaking at the World Extreme Medicine Conference. Dr Beat Walpoth, Director of Cardiovascular Research at the University Hospital of Geneva (http://www.hug-ge.ch/), Switzerland, is a leading surgeon and expert on rewarming victims of hypothermia using extracorporeal life support (ECLS).. The technique has been adapted from cardiac surgery as early as the 60s and 70s when patients were cooled down to core temperatures around 20°C in order to perform complex cardiac surgical repairs in a state of deep hypothermic cardiac arrest with good survival after rewarming to normothermia.. Dr Beat Walpoth said, Such operations would be impossible in normothermia because the brain has a tolerance to anoxia - not being perfused by blood - of about three minutes. However, when you cool the body to 20˚C, the brains tolerance is extended to around 30 minutes.. After the first successful rewarming of a patient in cardiac arrest with accidental hypothermia by Professor Ulrich Althaus ...
almost all fading kittens exhibit similar symptoms. Profound lethargy, low body temperature, pale gums, low respiratory rate, and failure to root and nurse or eat are nearly universal signs of the syndrome. However, these signs can be caused by a large number of problems. ( Inadequate mothering, Trauma and hypothermia are two causes of fading kitten syndrome that truly come on suddenly. Trauma occurs most frequently when a kitten falls from height or is crushed. Hypothermia occurs when kittens are separated from one another and the mother in a chilly environment. Note that hypothermia can be either a cause or a result of a fading kitten crisis. Almost all fading kittens in crisis will exhibit hypothermia. Infectious organisms are frequent culprits in fading kitten syndrome. Kittens are at risk of sepsis from bacterial infections. Viral infections with organisms such as feline herpesvirus, calicivirus, panleukopenia, FIV/feline AIDS, and feline leukemia virus may trigger the syndrome. Parasitic ...
The effects of small variations in brain temperature have been tested in a number of stroke and brain injury models. For example, intraischemic hypothermia after transient global ischemia protected the CA1 hippocampus and dorsolateral striatum from neuronal necrosis (142) and attenuated cognitive and sensory motor deficits (143). In dogs, mild hypothermia at 34°C also resulted in significant improvement in neurologic function after cardiac arrest (144). Mild temperature reductions dramatically reduced infarct volume after transient focal ischemia (145, 146), whereas profound temperature reductions (24°C) or extended periods of mild hypothermia were required to reduce infarct volume after permanent focal ischemia (147, 148).. One of the limitations of postischemic hypothermia appears to be the therapeutic window. Although dramatic protection is observed if hypothermia is induced during or immediately after the ischemic insult, lesser degrees of protection are observed as a delay in the ...
Disturbed homeostasis as a result of tissue stress can provoke leukocyte responses enabling recovery. Since mild hypothermia displays specific clinically relevant tissue-protective properties and interleukin (IL)-22 promotes healing at host/environment interfaces, effects of lowered ambient temperature on IL-22 were studied. We demonstrate that a 5h exposure of endotoxemic mice to 4°C reduces body temperature by 5.0 degrees and enhances splenic and colonic il22 gene expression. In contrast, tumor necrosis factor (TNF)-a and IL-17A were not increased. In vivo data on IL-22 were corroborated using murine splenocytes and human peripheral blood mononuclear cells (PBMC) cultured upon 33°C and polyclonal T cell activation. Upregulation by mild hypothermia of largely T-cell-derived IL-22 in PBMC required monocytes and associated with enhanced nuclear T-cell NFATc2. Notably, nuclear factor of activated T cells (NFAT) antagonism by cyclosporine A or FK506 impaired IL-22 upregulation at normothermia and
Cerebral arteries are innervated by nitric oxide (NO)-mediated vasodilator nerves, and hypoxia has been shown to attenuate neurogenic vasorelaxation. The present study examines the effects of hypothermia on neurogenic vasorelaxation and on the hypoxia-induced inhibition of the neurogenic vasorelaxation response. In isolated canine cerebral arteries, relaxant responses to transmural electrical stimulation (5 Hz for 40 s), mediated via NO synthesized from L-arginine, were not influenced by lowering the bathing media temperature from 37°C to 30°C but were attenuated at 25°C. On the other hand, relaxations caused by nicotine and exogenous NO were not significantly attenuated but were prolonged by cooling to 25°C. The responses associated with nerve stimulation by electrical pulses or nicotine were depressed by hypoxia (from about 500 mmHg of partial O,SUB,2,/SUB, pressure to about 45 mmHg) under normothermia. However, hypothermia at 25°C prevented the inhibition by hypoxia of the neurogenic ...
The primary objective of this Phase 2 HASTIER study, as an ancillary study to ICTuS 2, is to compare key imaging measurements for serial changes in recanalization and reperfusion between hypothermia and normothermia treatment arms as intermediate outcomes of treatment effect. Secondary exploratory analyses include imaging of the neurovascular impact of reperfusion with hypothermia and tPA, including blood-brain barrier changes or permeability, hemorrhagic transformation, and infarct growth.
Dont ever think that boating activities wont expose you to the risk of hypothermia. Wear rain gear when it rains. A windbreaker over a fleece jacket works very well to protect against the wind. Hypothermia can occur on what begins as a warm, sunny day. In remote areas, carry matches and go ashore if you need to build a fire. Also carry an extra jacket, hat, and blankets. Remember that, as a responsible operator, you should tell your passengers what to bring along for the outing.. ...
It is therefore difficult to distinguish between someone who is very cold and a corpse. Resuscitation continues until core temperature is normalised, at which time brain death can be confirmed or excluded.. The big problem with moderate to severe hypothermia is that heart muscle becomes very irritable at low temperature. Death occurs because of ventricular fibrillation (VF) - a rapid, dis-coordinated movement of the heart muscle which is ineffective at pumping blood. VF can be triggered by rough handling (a bumpy ambulance ride or a sudden jolt is sufficient). Standard treatment for VF is DC electric countershock, which attempts to reset the heart muscle. It is usually ineffective until core temperature exceeds 30°lC, however. CPR is performed until cardio-pulmonary bypass is initiated, or the victim warms up enough.. Frostbite or frostnip may arise in extremities whose temperature drops below freezing. At somewhat warmer temperatures immersion in cold water can lead to similar injuries ...

OBJECTIVE: Mild hypothermia has a protective effect on ischemic stroke, but the mechanisms remain elusive. Here, we investigated microRNA (miRNA) profiles and the specific role of miRNAs in ischemic stroke treated with mild hypothermia. MATERIALS AND METHODS: Male adult Sprague Dawley rats were subjected to focal transient cerebral ischemia. Mild hypothermia was induced by applying ice packs around the neck and head of the animals. miRNAs expression profiles were detected in ischemic stroke treated with mild therapeutic hypothermia through miRNA chips. Reverse transcription-polymerase chain reaction (RT-PCR) was used to verify the change of miRNA array. Western blot and adenosine triphosphate (ATP) assay kits were used to detect the changes of protein expression and ATP levels, respectively. miR-15b mimic and its control were injected into the right lateral ventricle 60 min before the induction of ischemia. RESULTS: The results showed that mild hypothermia affected miRNAs profiles expression. We ...
Intravenous delivery of cold fluids to reduce body temperature quickly after a heart attack and improve neurologic outcomes may not be as effective in children as it is in adults.
1. Plasma concentrations of glucose, lactate, amino acids, non-esterified fatty acids, glycerol, ketone bodies, insulin and cortisol were measured in 43 elderly patients with hypothermia. In 15 of these patients forearm arteriovenous differences were also measured. Core temperatures ranged from 25.9 to 35.5°C.. 2. The metabolic state was of mobilization of glycogen and triacylglycerol stores, with high plasma concentrations of lactate and lipid metabolites. The plasma concentration of glucose was raised in those with hypothermia of a short duration (,6 h). In other patients it was low in those with core temperatures around 30°C, but below this temperature it was variable and often high. Concentrations of other metabolites or hormones were not related to core temperature.. 3. Plasma concentrations of cortisol were high and positively correlated with those of lactate and glycerol, suggesting active involvement in stimulation of muscle glycogenolysis and of lipolysis.. 4. Plasma concentrations of ...
During therapeutic hypothermia, doctors reduce a patients body temperature to prevent cellular damage. See how therapeutic hypothermia saves lives.
The weather is extremely unpredictable. One day its 60 degrees and raining, the next its 80 degrees with sunshine. Winters can be even worse with unexpected cold fronts. With extremely cold temperatures, hypothermia is a possibility for dogs. Hypothermia, occurring in both humans and pets, is a condition characterized by abnormally low body temperatures. There are three phases of hypothermia: mild, classified as a body temperature of 90-99 degrees Fahrenheit; moderate, classified as a body temperature of 82-90 degrees Fahrenheit; and severe, classified as a body temperature of less than 82 degrees Fahrenheit. With hypothermia, the dog is no longer able to control a normal body temperature resulting in an abnormal heartbeat and difficulties breathing. Generally, hypothermia results from spending too much time outside in the cold. Although there is not a specific time limit for a given temperature a dog should be left outside, Dr. Stacy Eckman, lecturer at the Texas A&M College of Veterinary Medicine

We normally think of exposure to cold environmental temperatures, particularly combined with windy and/or wet conditions, as the cause of most cases of hypothermia, but in the veterinary setting, anesthesia and surgery are most typically to blame. Some anesthetic agents disrupt the physiologic processes that regulate temperature and cause blood vessels to dilate thereby increasing heat loss. Surgery often involves exposing internal organs to colder than normal temperatures, blood loss, and the administration of cool intravenous fluids. Certain diseases (e.g., shock, poisonings) can also lead to hypothermia in dogs ...
Patients will be randomized into either a normothermic group (target surgical temperature 36.5°C) or a hypothermic group (target surgical temperature 33°C). Hypothermic patients will be surface-cooled during the procedure, and warmed immediately after the aneurysm clip is placed. All patients will receive a standardized anesthetic, and their surgeries will be performed according to local standards.
