A response by the BARORECEPTORS to increased BLOOD PRESSURE. Increased pressure stretches BLOOD VESSELS which activates the baroreceptors in the vessel walls. The net response of the CENTRAL NERVOUS SYSTEM is a reduction of central sympathetic outflow. This reduces blood pressure both by decreasing peripheral VASCULAR RESISTANCE and by lowering CARDIAC OUTPUT. Because the baroreceptors are tonically active, the baroreflex can compensate rapidly for both increases and decreases in blood pressure.

Spinal cord-evoked potentials and muscle responses evoked by transcranial magnetic stimulation in 10 awake human subjects. (1/807)

Transcranial magnetic stimulation (TCMS) causes leg muscle contractions, but the neural structures in the brain that are activated by TCMS and their relationship to these leg muscle responses are not clearly understood. To elucidate this, we concomitantly recorded leg muscle responses and thoracic spinal cord-evoked potentials (SCEPs) after TCMS for the first time in 10 awake, neurologically intact human subjects. In this report we provide evidence of direct and indirect activation of corticospinal neurons after TCMS. In three subjects, SCEP threshold (T) stimulus intensities recruited both the D wave (direct activation of corticospinal neurons) and the first I wave (I1, indirect activation of corticospinal neurons). In one subject, the D, I1, and I2 waves were recruited simultaneously, and in another subject, the I1 and I2 waves were recruited simultaneously. In the remaining five subjects, only the I1 wave was recruited first. More waves were recruited as the stimulus intensity increased. The presence of D and I waves in all subjects at low stimulus intensities verified that TCMS directly and indirectly activated corticospinal neurons supplying the lower extremities. Leg muscle responses were usually contingent on the SCEP containing at least four waves (D, I1, I2, and I3).  (+info)

Effect of obesity and erect/supine posture on lateral cephalometry: relationship to sleep-disordered breathing. (2/807)

Craniofacial and upper airway anatomy, obesity and posture may all play a role in compromising upper airway patency in patients with the sleep apnoea/hypopnoea syndrome. The aim of this study was to investigate the relationship between obesity, facial structure and severity of sleep-disordered breathing using lateral cephalometric measurements and to assess the effect of body posture on cephalometric measurements of upper airway calibre variables in obese and non-obese subjects. Lateral cephalometry was carried out in erect and supine postures in 73 awake male subjects randomly selected from patients referred for polysomnography who had a wide range of apnoea/hypopnoea frequencies (1-131 events x h sleep(-1)). Subjects were divided into non-obese (body mass index (BMI) < 30 kg x m(-2); n=42) and obese (BMI > or = 30 kg x m(-2); n=31) groups. Significant but weak correlations were found between apnoea/hypopnoea index (AHI) and measurements reflecting upper airway dimensions: uvular protrusion-posterior pharyngeal wall (r=-0.26, p<0.05) and hyoid-posterior pharyngeal wall (r=0.26, p<0.05). Multiple regression using both upper airway dimensions improved the correlation to AHI (r=0.34, p=0.01). Obese subjects had greater hyoid-posterior pharyngeal wall distances than non-obese subjects, both erect (42+/-5 versus 39+/-4 mm, respectively (mean+/-SD) p<0.01) and supine (43+/-5 versus 40+/-4 mm, p<0.05). Skeletal craniofacial structure was similar in obese and non-obese subjects. In conclusion, measurements reflecting upper airway size were correlated with the severity of sleep-disordered breathing. Differences in upper airway size measurements between obese and non-obese subjects were independent of bony craniofacial structure.  (+info)

Mechanism for the posture-specific plasma volume increase after a single intense exercise protocol. (3/807)

To test the hypothesis that exercise-induced hypervolemia is a posture-dependent process, we measured plasma volume, plasma albumin content, and renal function in seven healthy subjects for 22 h after single upright (Up) or supine (Sup) intense (85% peak oxygen consumption rate) exercise. This posture was maintained for 5 h after exercise. Plasma volume decreased during exercise but returned to control levels by 5 h of recovery in both postures. By 22 h of recovery, plasma volume increased 2.4 +/- 0.8 ml/kg in Up but decreased 2.1 +/- 0.8 ml/kg in Sup. The plasma volume expansion in Up was accompanied by an increase in plasma albumin content (0.11 +/- 0.04 g/kg; P < 0.05). Plasma albumin content was unchanged in Sup. Urine volume and sodium clearance were lower in Up than Sup (P < 0.05) by 5 h of recovery. These data suggest that increased plasma albumin content contributes to the acute phase of exercise-induced hypervolemia. More importantly, the mechanism by which exercise influences the distribution of albumin between extra- and intravascular stores after exercise is altered by posture and is unknown. We speculate that factors associated with postural changes (e.g., central venous pressure) modify the increase in plasma albumin content and the plasma volume expansion after exercise.  (+info)

Brain activation during maintenance of standing postures in humans. (4/807)

The regulatory mechanism of bipedal standing in humans remains to be elucidated. We investigated neural substrates for maintaining standing postures in humans using PET with our mobile gantry PET system. Normal volunteers were instructed to adopt several postures: supine with eyes open toward a target; standing with feet together and eyes open or eyes closed; and standing on one foot or with two feet in a tandem relationship with eyes open toward the target. Compared with the supine posture, standing with feet together activated the cerebellar anterior lobe and the right visual cortex (Brodmann area 18/19), and standing on one foot increased cerebral blood flow in the cerebellar anterior vermis and the posterior lobe lateral cortex ipsilateral to the weight-bearing side. Standing in tandem was accompanied by activation within the visual association cortex, the anterior and posterior vermis as well as within the midbrain. Standing with eyes closed activated the prefrontal cortex (Brodmann area 8/9). Our findings confirmed that the cerebellar vermis efferent system plays an important role in maintenance of standing posture and suggested that the visual association cortex may subserve regulating postural equilibrium while standing.  (+info)

Abnormal norepinephrine clearance and adrenergic receptor sensitivity in idiopathic orthostatic intolerance. (5/807)

BACKGROUND: Chronic orthostatic intolerance (OI) is characterized by symptoms of inadequate cerebral perfusion with standing, in the absence of significant orthostatic hypotension. A heart rate increase of >/=30 bpm is typical. Possible underlying pathophysiologies include hypovolemia, partial dysautonomia, or a primary hyperadrenergic state. We tested the hypothesis that patients with OI have functional abnormalities in autonomic neurons regulating cardiovascular responses. METHODS AND RESULTS: Thirteen patients with chronic OI and 10 control subjects underwent a battery of autonomic tests. Systemic norepinephrine (NE) kinetics were determined with the patients supine and standing before and after tyramine administration. In addition, baroreflex sensitivity, hemodynamic responses to bolus injections of adrenergic agonists, and intrinsic heart rate were determined. Resting supine NE spillover and clearance were similar in both groups. With standing, patients had a greater decrease in NE clearance than control subjects (55+/-5% versus 30+/-7%, P<0.02). After tyramine, NE spillover did not change significantly in patients but increased 50+/-10% in control subjects (P<0.001). The dose of isoproterenol required to increase heart rate 25 bpm was lower in patients than in control subjects (0.5+/-0.05 versus 1.0+/-0.1 microg, P<0.005), and the dose of phenylephrine required to increase systolic blood pressure 25 mm Hg was lower in patients than control subjects (105+/-11 versus 210+/-12 microg, P<0.001). Baroreflex sensitivity was lower in patients (12+/-1 versus 18+/-2 ms/mm Hg, P<0.02), but the intrinsic heart rate was similar in both groups. CONCLUSIONS: The decreased NE clearance with standing, resistance to the NE-releasing effect of tyramine, and increased sensitivity to adrenergic agonists demonstrate dramatically disordered sympathetic cardiovascular regulation in patients with chronic OI.  (+info)

Incidence of bradycardia during recovery from spinal anaesthesia: influence of patient position. (6/807)

We administered 0.5% plain bupivacaine 4 ml intrathecally (L2-3 or L3-4) in three groups of 20 patients, according to the position in which they were nursed in the post-anaesthesia care unit (PACU): supine horizontal, 30 degrees Trendelenburg or hammock position (trunk and legs 30 degrees elevated). Patients were observed until anaesthesia descended to less than S1. The incidence of severe bradycardia (heart rate < 50 beat min-1) in the PACU was significantly higher in patients in the Trendelenburg position (60%) than in the horizontal (20%, P < 0.01) or hammock (10%, P < 0.005) position. After 90 min, following admission to the PACU, only patients in the hammock position did not have severe bradycardia. In this late phase, the incidence of severe bradycardia in the Trendelenburg group was 35% (P < 0.005) and 10% in patients in the supine horizontal position. In four patients, severe bradycardia first occurred later than 90 min after admission to the PACU. The latest occurrence of severe bradycardia was recorded 320 min after admission to the PACU. We conclude that for recovery from spinal anaesthesia, the Trendelenburg position should not be used and the hammock position is preferred.  (+info)

Pulmonary perfusion is more uniform in the prone than in the supine position: scintigraphy in healthy humans. (7/807)

The main purpose of this study was to find out whether the dominant dorsal lung perfusion while supine changes to a dominant ventral lung perfusion while prone. Regional distribution of pulmonary blood flow was determined in 10 healthy volunteers. The subjects were studied in both prone and supine positions with and without lung distension caused by 10 cmH2O of continuous positive airway pressure (CPAP). Radiolabeled macroaggregates of albumin, rapidly trapped by pulmonary capillaries in proportion to blood flow, were injected intravenously. Tomographic gamma camera examinations (single-photon-emission computed tomography) were performed after injections in the different positions. All data acquisitions were made with the subject in the supine position. CPAP enhanced perfusion differences along the gravitational axis, which was more pronounced in the supine than prone position. Diaphragmatic sections of the lung had a more uniform pulmonary blood flow distribution in the prone than supine position during both normal and CPAP breathing. It was concluded that the dominant dorsal lung perfusion observed when the subjects were supine was not changed into a dominant ventral lung perfusion when the subjects were prone. Lung perfusion was more uniformly distributed in the prone compared with in the supine position, a difference that was more marked during total lung distension (CPAP) than during normal breathing.  (+info)

Human muscle performance and PCr hydrolysis with varied inspired oxygen fractions: a 31P-MRS study. (8/807)

The purpose of this study was to use 31P-magnetic resonance spectroscopy to examine the relationships among muscle PCr hydrolysis, intracellular H+ concentration accumulation, and muscle performance during incremental exercise during the inspiration of gas mixtures containing different fractions of inspired O2 (FIO2). We hypothesized that lower FIO2 would result in a greater disruption of intracellular homeostasis at submaximal workloads and thereby initiate an earlier onset of fatigue. Six subjects performed plantar flexion exercise on three separate occasions with the only variable altered for each exercise bout being the FIO2 (either 0.1, 0.21, or 1.00 O2 in balance N2). Work rate was increased (1-W increments starting at 0 W) every 2 min until exhaustion. Time to exhaustion (and thereby workload achieved) was significantly (P < 0.05) greater as FIO2 was increased. Muscle phosphocreatine (PCr) concentration, Pi concentration, and pH at exhaustion were not significantly different among the three FIO2 conditions. However, muscle PCr concentration and pH were significantly reduced at identical submaximal workloads (and thereby equivalent rates of respiration) above 4-5 W during the lowest FIO2 condition compared with the other two FIO2 conditions. These results demonstrate that exhaustion during all FIO2 occurred when a particular intracellular environment was achieved and suggest that during the lowest FIO2 condition, the greater PCr hydrolysis and intracellular acidosis at submaximal workloads may have contributed to the significantly earlier time to exhaustion.  (+info)

This study suggests that acute stroke patients with some disability spend the vast majority of their sleep in the supine position. Regardless of the cause, given the known association between supine posture and AHI, this finding has important implications for the assessment of OSA severity in the acute stroke period, as well as possible postural treatment options for stroke patients with OSA. The effects of supine positioning may be even more important in the more severely disabled patients, as those with a higher NIHSS spend an even greater percent of sleep time in the supine position.. Supine sleep was much more prominent (median 100%) in our stroke population than other reported populations. Other studies have reported supine sleep to represent 25% of sleep in those without a sleep disorder, 30% to 50% in those with positional OSA,15-17 27% in those with nonpositional OSA,15 and 42% in those being screened for OSA in an outpatient laboratory where subjects were encouraged to sleep ...

OBJECTIVE: To test the null hypothesis that, after 28 weeks of gestation, uterine blood flow during supine rest and supine exercise is no different than uterine blood flow at left-lateral rest. DESIGN: In vivo experimental study in pregnant women. SETTING: Department of Obstetrics, MetroHealth Medical Center, Cleveland, OH, USA. POPULATION: Fourteen, physically active, late-pregnant women who continued supine exercise throughout gestation. METHODS: Studies were carried out between 29 and 38 weeks of gestation. Maternal blood pressure, maternal heart rate, and ultrasound estimates of volume blood flow in the right ascending branch of the uterine artery were obtained serially at rest in the left-lateral position, at rest in the supine position, during and immediately after 10 minutes of supine exercise, and again at rest in the left-lateral position. Exercise sessions included alternating 60- to 90-second periods of abdominal crunches and leg exercise at moderate/high intensity (Borgs rating of ...
The correct answer is C. RebelEM covered this paper last week.. It is a non-inferiority trial comparing VL in supine position and BUHE DL to DL in supine position. Because it was a non inferiority trial, we can not make a statement about superiority. DL in BUHE was non inferior to videolaryngoscopy. Intubation with video took 8 seconds longer than DL in BUHE. The authors did find both BUHE and videolaryngoscopy to give better views of the glottis compared to DL in supine position. This trial was conducted in a controlled and elective setting in the operating room though, so might not be applicable to our Emergency Department patients. Furthermore, the primary outcome is not patient centered. To me it is not clear why the authors chose not to include a group using VL in BUHE position.. ...
Methods: Thirty consecutive morbidly obese patients undergoing gastric banding were investigated. All subjects were studied the day before surgery (T0) and on postoperative day one (T1). Forced Vital Capacity (FVC) was measured, together with heart rate, mean arterial pressure and respiratory rate. At T0 measurements were taken in a random fashion with subjects in upright and in supine position. Subjects were then investigated after surgery in the supine position (T1). Postoperative pain was assessed at T1 using visual analogue scale. Intraoperative variables were also collected ...

The heart pumps a volume of blood into the lungs which after getting oxygenated is transported back to heart. This oxygenated blood is then pumped out of the heart and into the aorta and subsequently into the systemic circulation. As a consequence, at any given time the lungs (pulmonary vasculature) contain around 500ml of blood, thereby allowing them to function as a reservoir of the blood. This reservoir volume is increased by 500 ml when the person is in the supine or lying down position. This is because in supine position theres an increased venous return (due to the effect of gravity) to the right heart from the peripheries and therefore more blood accumulates in the central parts of body. Upon standing up, this extra 500ml of blood gets redistributed under the effect of gravity, to the now more dependent parts of the body which includes the peripheral tissues and the lower extremities..

The introduction of the supine sleep position to reduce the prevalence of Sudden Infant Death Syndrome has not altered the timing or sequence of infant rolling abilities, say authors of an article published online in Early Human Development. This information is valuable to health care providers involved in the surveillance of infants development, they add. Original normative age estimates for these 2 motor abilities are still appropriate. The aim of this study was to compare the order and age of emergence of rolling prone to supine and supine to prone before the introduction of back to sleep guidelines and 20 years after their introduction. The original normative data for the Alberta Infant Motor Scale (AIMS) were collected just prior to the introduction of back to sleep guidelines in 1992. Currently these norms are being reevaluated. Data of rolling patterns of infants 36 weeks of age or younger from the original sample (n=1,114) and the contemporary sample (n=351) were evaluated to compare ...
Background: Because stretch of the atrial myocardium is proarrhythmic for atrial fibrillation (AF) and a left lateral body position increases atrial dimensions in humans, we hypothesized that left lateral recumbence is a frequent AF-triggering body position in AF patients.Methods: We performed a questionnaire study of symptomatic paroxysmal AF (episodes of AF | 1 week) patients scheduled for a first AF ablation therapy at Catharina Hospital, Eindhoven, the Netherlands and at University Hospital, Bordeaux, France.Results: Ninety-four symptomatic paroxysmal AF patients were included [mean age 61 ± 11 years, median AF history of 29(48) months, 31% were females]. Twenty-two percent of patients reported a specific body position as a trigger of their AF symptoms. The triggering body position was left lateral position in 57% of cases, supine position in 33%, right lateral position in 10%, and prone position in 5% (p = 0.003 overall difference in prevalence). Patients with positional AF had a higher body mass

Methods: We compared plasma concentrations of free metanephrines in samples from patients with primary hypertension obtained after supine rest with those obtained in the sitting position without preceding rest. In the new blood pressure guidelines, they stated systolic blood pressure has been reported to be 3-10 mmHg higher in the supine (lying) than the seated position. of mercury, respectively.

Objective. To evaluate the potential relation between body position and sleep characteristics in normal infants.. Patients. Two groups of 3-month-old healthy infants were evaluated: 40 infants who usually slept supine, and 40 who usually slept prone. The two groups were matched for gender, gestational age, postnatal age, birth weight, and total recording time.. Recording techniques. The 80 infants were studied polygraphically during one night in the pediatric sleep laboratory. They were allowed to fall asleep in their usual sleep position, and every 3 hours were gently turned from prone to supine, or from supine to prone.. Results. In each group, 6 infants were excluded from the analysis, because they woke up after having been turned over. In both groups, no significant difference was seen between the prone and the supine body positions for the following variables: number of sleep state changes; number of gross body movements; percent of rapid eye movement sleep; saturation with oxygen, arterial ...
Paradoxically, for traditional reasons, it was kidney stone surgery in the prone position that became well-known world wide in spite of the fact that the intervention performed in the supine position has several advantages both from an anesthesiological and an operative aspect. Interestingly, in Mediterranean countries, the supine position is used in routine practice to treat large kidney stones, Zoltán Kiss told hirek.unideb.hu. According to the specialist the supine position typical in Hungary makes surgery particularly difficult. One difficulty is that the staff have to turn patients over during surgery and there are also patients who, due to, e.g., overweight or severe respiratory disease, cannot even be turned on their stomachs.. During the novel type of surgery which is regarded as a pioneering one special cushions are used to make sure the patient is in the appropriate, supine position. Then the kidney stones are removed through a 1 cm incison of the skin using endoscopy.. - Some of the ...

It remains unclear whether orthostatic stress evokes regional differences in cerebral blood flow. The present study compared blood flow in the internal carotid (ICA) and vertebral (VA) arteries during orthostatic stress (60° head-up tilt; HUT) in 6 healthy young men. ICA and VA blood flow were measured using Doppler ultrasonography. Dynamic cerebral autoregulation was also determined during supine (Supine) and HUT conditions, from the rate of regulation (RoR) in cerebrovascular conductance of the ICA and VA during acute hypotension induced by the release of bilateral thigh cuffs. The HUT decreased ICA blood flow by -9.4 ± 1.7% (P ,0.01 vs. Supine), leaving ICA conductance unchanged. In contrast, there was no significant difference in VA blood flow between Supine and HUT and VA conductance increased (+12.9 ± 0.8 %, P ,0.01). In addition, dynamic CA in both the ICA and VA was attenuated during HUT and the magnitude of the attenuation in RoR was greater in the VA [0.25 ± 0.03 /s Supine vs. 0.16 ...
Changes in the kinetics of the creatine kinase (CK) shuttle are sensitive markers of cardiac energetics but are typically measured at rest and in the prone position. This study aims to measure CK kinetics during pharmacological stress at 3 T, with measurement in the supine position. A shorter stressed saturation transfer (StreST) extension to the triple repetition time saturation transfer (TRiST) method is proposed. We assess scanning in a supine position and validate the MR measurement against biopsy assay of CK activity. We report normal ranges of stress CK forward rate (kf CK ) for healthy volunteers and obese patients. TRiST measures kf CK in 40 min at 3 T. StreST extends the previously developed TRiST to also make a further kf CK measurement during |20 min of dobutamine stress. We test our TRiST implementation in skeletal muscle and myocardium in both prone and supine positions. We evaluate StreST in the myocardium of six healthy volunteers and 34 obese subjects. We validated MR-measured kf CK
Dear Dr. Andersson:. More than two decades have passed since the first time my colleagues and I described the percutaneous nephroscopy technique in supine position [1,2,3]. Curiously, it is only during the last 5 years that interest in this technique has risen significantly.. Very few urologists have dared to perform this technique; when they do, they become its best defenders. Some of them have published their results [4,5,6]. Many others have not, despite having successful experience with it.. Today, many publications and editorial comments are appearing about the percutaneous nephrolithotomy in supine position [7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27]. These publications do nothing else but support the conclusions we already pointed out 22 years ago. Mainly, that it is an easy to perform and reproducible technique that has a smaller risk of hands irradiation and a more comfortable working position for the urologist. Additionally, that with this technique the calicial ...
Aim: Ultrasound assessment of morphological parameters of the internal jugular veins and vertebral veins in healthy individuals as well as their dependence on the patients position. Material: The examinations were conducted in 185 healthy individuals (101 females and 84 males) aged 18-89. Ultrasound examinations were conducted with the use of a linear probe with the frequency of 5-9 MHz in the supine (0°) and sitting position (90°). Results: In 154 cases (83.2%) on the left side and in 150 cases (81.1%) on the right side, the jugular veins were completely closed in the sitting position. In 31 cases (16.8%) on the left side and in 35 cases (18.9%) on the right side, they were merely narrowed. By contrast with the jugular veins, the cross-sectional area (CSA) of the vertebral veins was greater in the sitting position than in the supine position in a statistically signifi cant way. The CSA values of the jugular veins in the supine position ranged from 0 cm2 to 4.3 cm2. There were no ...

Our study demonstrated that the average excursions of the bilateral tsh receptor during tidal breathing (right: 11.0 mm, 95% CI 10.4 to 11.6 mm; left: 14.9 mm, 95% CI 14.2 to 15.5 mm) were numerically less than those during forced breathing in previous studies using other modalities 2; 7 ; 8. Using fluoroscopy, Alexander reported that the average right excursion was 27.5 mm and the average left excursion was 31.5 mm during forced breathing in the standing position in 127 patients (2). Using ultrasound, Harris et al. reported that the average right diaphragm excursion was 48 mm during forced breathing in the supine position in 53 healthy adults (7). Using MR fluoroscopy, Gierada et al. reported that the average right excursion was 44 mm and the average left excursion was 42 mm during forced breathing in the supine position in 10 healthy volunteers (8). The difference in diaphragmatic excursion during tidal breathing versus forced breathing is unsurprising ...

A stent crimping tool for firmly and uniformly crimping a stent onto a balloon catheter is constructed from a stationary plate and a sliding platform connected to the stationary plate and slidable linearly relative thereto. A closing plate is hinged to the sliding platform so that it at least partially overlies the stationary plate in a down position, and swings away from the stationary plate to an up position, whereby the stent already having been hand crimped onto the balloon catheter is placed on the stationary plate from a lateral position, and the closing plate is moved to the down position to hold the stent between the closing plate and the stationary plate so that an external force on the closing plate as well as translational motion of the closing plate together crimp the stent onto the balloon catheter. The surfaces engaging the stent may be covered by elastomeric pads having ridges corresponding in location to respective rings or cylindrical elements of the stent.
