Ketamine-induced peripheral analgesia in rats. (1/1131)

AIM: To examine whether ketamine may directly act at peripheral nociceptors to produce analgesia. METHODS: Wistar rats were anesthetized with urethane. As a nociceptive flexion reflex (FR), C responses from the posterior biceps semitendinosus (PBST) muscle was evoked by electrical stimulation (2 ms, 80 V, 2-3 pulses, 0.5 Hz) via a pair of stainless steel needles inserted subcutaneously applied to the two toes of ipsilateral hindpw. RESULTS: Subcutaneous injection of ketamine (36 mmol.L-1, 5 microL) into the ipsilateral hindpaw produced an inhibition of C responses. At 9 min after application of ketamine, injection of naloxone (1%, 5 microL) into the same area annulled ketamine-induced inhibition. CONCLUSION: Ketamine as a dissociate anesthetic acts on peripheral nociceptors to produce analgesia, which is related to activity of peripheral opioid receptors.  (+info)

Mechanisms of bronchoprotection by anesthetic induction agents: propofol versus ketamine. (2/1131)

BACKGROUND: Propofol and ketamine have been purported to decrease bronchoconstriction during induction of anesthesia and intubation. Whether they act on airway smooth muscle or through neural reflexes has not been determined. We compared propofol and ketamine to attenuate the direct activation of airway smooth muscle by methacholine and limit neurally mediated bronchoconstriction (vagal nerve stimulation). METHODS: After approval from the institutional review board, eight sheep were anesthetized with pentobarbital, paralyzed, and ventilated. After left thoracotomy, the bronchial artery was cannulated and perfused. In random order, 5 mg/ml concentrations of propofol, ketamine, and thiopental were infused into the bronchial artery at rates of 0.06, 0.20, and 0.60 ml/min. After 10 min, airway resistance was measured before and after vagal nerve stimulation and methacholine given via the bronchial artery. Data were expressed as a percent of baseline response before infusion of drug and analyzed by analysis of variance with significance set at P< or =0.05. RESULTS: Systemic blood pressure was not affected by any of the drugs (P>0.46). Baseline airway resistance was not different among the three agents (P = 0.56) or by dose (P = 0.96). Infusion of propofol and ketamine into the bronchial artery caused a dose-dependent attenuation of the vagal nerve stimulation-induced bronchoconstriction to 26+/-11% and 8+/-2% of maximum, respectively (P<0.0001). In addition, propofol caused a significant decrease in the methacholine-induced bronchoconstriction to 43+/-27% of maximum at the highest concentration (P = 0.05) CONCLUSIONS: The local bronchoprotective effects of ketamine and propofol on airways is through neurally mediated mechanisms. Although the direct effects on airway smooth muscle occur at high concentrations, these are unlikely to be of primary clinical relevance.  (+info)

Effect of i.v. ketamine in combination with epidural bupivacaine or epidural morphine on postoperative pain and wound tenderness after renal surgery. (3/1131)

We studied 60 patients undergoing operation on the kidney with combined general and epidural anaesthesia, in a double-blind, randomized, controlled study. Patients were allocated to receive a preoperative bolus dose of ketamine 10 mg i.v., followed by an i.v. infusion of ketamine 10 mg h-1 for 48 h after operation, or placebo. During the first 24 h after surgery, all patients received 4 ml h-1 of epidural bupivacaine 2.5 mg ml-1. From 24 to 48 h after operation, patients received epidural morphine 0.2 mg h-1 preceded by a bolus dose of 2 mg. In addition, patient-controlled analgesia (PCA) with i.v. morphine (2.5 mg, lockout time 15 min) was offered from 0 to 48 h after operation. Patients who received ketamine felt significantly more sedated at 0-24 h, but not at 24-48 h after operation, compared with patients who received placebo (P = 0.002 and P = 0.127, respectively). There were no significant differences in pain (VAS) at rest, during mobilization or cough, PCA morphine consumption, sensory block to pinprick, pressure pain detection threshold assessed with an algometer, touch and pain detection thresholds assessed with von Frey hairs, peak flow or side effects other than sedation. The power of detecting a reduction in VAS scores of 20 mm in our study was 80% at the 5% significance level. We conclude that we were unable to demonstrate an (additive) analgesic or opioid sparing effect of ketamine 10 mg h-1 i.v. combined with epidural bupivacaine at 0-24 h, or epidural morphine at 24-48 h after renal surgery.  (+info)

Impact of network activity on the integrative properties of neocortical pyramidal neurons in vivo. (4/1131)

During wakefulness, neocortical neurons are subjected to an intense synaptic bombardment. To assess the consequences of this background activity for the integrative properties of pyramidal neurons, we constrained biophysical models with in vivo intracellular data obtained in anesthetized cats during periods of intense network activity similar to that observed in the waking state. In pyramidal cells of the parietal cortex (area 5-7), synaptic activity was responsible for an approximately fivefold decrease in input resistance (Rin), a more depolarized membrane potential (Vm), and a marked increase in the amplitude of Vm fluctuations, as determined by comparing the same cells before and after microperfusion of tetrodotoxin (TTX). The model was constrained by measurements of Rin, by the average value and standard deviation of the Vm measured from epochs of intense synaptic activity recorded with KAc or KCl-filled pipettes as well as the values measured in the same cells after TTX. To reproduce all experimental results, the simulated synaptic activity had to be of relatively high frequency (1-5 Hz) at excitatory and inhibitory synapses. In addition, synaptic inputs had to be significantly correlated (correlation coefficient approximately 0.1) to reproduce the amplitude of Vm fluctuations recorded experimentally. The presence of voltage-dependent K+ currents, estimated from current-voltage relations after TTX, affected these parameters by <10%. The model predicts that the conductance due to synaptic activity is 7-30 times larger than the somatic leak conductance to be consistent with the approximately fivefold change in Rin. The impact of this massive increase in conductance on dendritic attenuation was investigated for passive neurons and neurons with voltage-dependent Na+/K+ currents in soma and dendrites. In passive neurons, correlated synaptic bombardment had a major influence on dendritic attenuation. The electrotonic attenuation of simulated synaptic inputs was enhanced greatly in the presence of synaptic bombardment, with distal synapses having minimal effects at the soma. Similarly, in the presence of dendritic voltage-dependent currents, the convergence of hundreds of synaptic inputs was required to evoke action potentials reliably. In this case, however, dendritic voltage-dependent currents minimized the variability due to input location, with distal apical synapses being as effective as synapses on basal dendrites. In conclusion, this combination of intracellular and computational data suggests that, during low-amplitude fast electroencephalographic activity, neocortical neurons are bombarded continuously by correlated synaptic inputs at high frequency, which significantly affect their integrative properties. A series of predictions are suggested to test this model.  (+info)

Haemodynamic stability and ketamine-alfentanil anaesthetic induction. (5/1131)

We have determined if alfentanil could obtund the haemodynamic instability commonly seen at induction of anaesthesia with ketamine. Five groups of ASA I and II patients received ketamine 1 mg kg-1 i.v., preceded by saline (group 1) or alfentanil 10, 20, 30 or 40 micrograms kg-1 (groups 2-5, respectively). Heart rate (HR), mean arterial pressure (AP), postoperative patient complaints and dysphoria were noted. All groups showed increases (P < 0.05) in both HR and AP after administration of ketamine, which were progressively smaller as the dose of alfentanil increased. After tracheal intubation, all groups showed further increases in HR and AP, with groups 3-5 (alfentanil 20-40 micrograms kg-1) showing significant obtundation (P < 0.05) of these increases compared with group 1. No patient in any group reported postoperative dysphoria or dissatisfaction with their anaesthetic. Ketamine 1 mg kg-1 with alfentanil 20-40 micrograms kg-1 provided statistically significant obtundation of the haemodynamic instability that is common with ketamine alone.  (+info)

Prolonged analgesic effect of ketamine, an N-methyl-D-aspartate receptor inhibitor, in patients with chronic pain. (6/1131)

We examined the role of N-methyl-D-aspartate (NMDA) receptors in chronic (pathological) pain in humans by using the NMDA receptor antagonist ketamine as a probe. Thirty patients with neuropathic pain in the trigeminal area were given an i.m. injection of ketamine 0.4 mg/kg combined with midazolam 0.05 mg/kg. Pethidine 1.0 mg/kg served as a control. Three different response patterns were observed. Ketamine caused a long-term (6-24 h) analgesic effect partly dissociated from the mental side effects in 8 of the 26 patients who completed the study; these patients also had a slight analgesic effect of pethidine. In nine patients, ketamine caused a short-lasting (<2 h) analgesic effect closely associated with the mental side effects, whereas pethidine caused little or no analgesia. The remaining nine patients did not experience any reduction of pain after either drug in spite of characteristic side effects. One week after the i.m. challenge the patients received either 4.0 mg/kg ketamine hydrochloride or placebo capsules to be taken orally as a nightly dose for three consecutive nights. Five of the eight patients who had a long-term analgesic effect of the i.m. challenge reported decreased pain on days after ketamine. None of the others reported an analgesic effect. The phenomenon of long-term depression of pain in a subgroup of patients was thus confirmed when ketamine was given p.o. These findings indicate that NMDA receptors are involved in the perception and maintenance of pathological pain in some patients. In others, pain appears to be mediated by NMDA receptor-independent mechanisms. We suggest that NMDA receptor-independent transmission in central pain pathways may contribute to the reduced efficiency of analgesic drugs often seen in chronic pain states.  (+info)

Acid-base disturbance during hemorrhage in rats: significant role of strong inorganic ions. (7/1131)

The present study tests the hypothesis that changes in the strong inorganic ion concentrations contribute significantly to the acid-base disturbance that develops during hemorrhage in the arterial plasma of rats in addition to lactate concentration ([Lac-]) increase. The physicochemical origins for this acid-base disorder were studied during acute, graded hemorrhage (10, 20, and 30% loss of blood volume) in three groups of rats: conscious, anesthetized with ketamine, and anesthetized with urethan. The results support the hypothesis examined: strong-ion difference (SID) decreased in the arterial plasma of all groups studied because of an early imbalance in the main strong inorganic ions during initial hemorrhagic phase. Moreover, changes in plasma [Lac-] contributed to SID decrease in a later hemorrhagic phase (after 10% hemorrhage in urethan-anesthetized, after 20% hemorrhage in ketamine-anesthetized, and after 30% hemorrhage in conscious group). Inorganic ion changes were due to both dilution of the vascular compartment and ion exchange with extravascular space and red blood cells, as compensation for blood volume depletion and hypocapnia. Nevertheless, anesthetized rats were less able than conscious rats to preserve normal arterial pH during hemorrhage, mainly because of an impaired peripheral tissue condition and incomplete ventilatory compensation.  (+info)

Actions of ketamine and its isomers on contractility and calcium transients in human myocardium. (8/1131)

BACKGROUND: Ketamine has a species-dependent inotropic effect on myocardium. The authors' aim was to investigate the direct inotropic effect and the corresponding intracellular Ca2+ transients of ketamine and its isomers on human myocardium. METHODS: Right auricular myocardial strips obtained during open heart surgery were exposed to increasing concentrations (73 microM, 360 microM, and 730 microM) of racemic ketamine (n = 12), S(+)-ketamine (n = 12), or R(-)-ketamine (n = 11). Isometric force, isotonic shortening, contractility, relaxation, and time to maximal isotonic and isometric force were assessed. Ten muscle strips in each group were loaded with the calcium-sensitive fluorescent dye FURA-2/AM for simultaneous measurements of calcium transients. RESULTS: Compared with the initial control maximal isometric developed force, maximal isotonic shortening amplitude, contractility, and relaxation increased by 12.5-22.4% after perfusion with S(+)-ketamine at the concentration of 73 microM (P < 0.05). In contrast, no changes were seen after addition of 73 microM R(-)-ketamine. The effect of racemic ketamine (73 microM) was between that of the two isomers. At the highest concentration (730 microM) ketamine and its isomers decreased maximal isometric developed force, maximal shortening amplitude, contractility, and relaxation by 26.8-57.4% (P < 0.05), accompanied by a significant decrease of the intracellular calcium transient (by 21.0-32.2%, P < 0.05). CONCLUSIONS: In contrast to R(-)-ketamine, S(+)-ketamine increased isometric force, isotonic shortening, contractility, and relaxation at low concentrations (73 microM) compared with the initial control. At higher concentrations (730 microM) a direct negative inotropic action was observed after perfusion with ketamine and its isomers, which was accompanied by a decreased intracellular Ca2+ transient.  (+info)

The World Health Organizations Expert Committee on Drug Dependence are gathered this week in Geneva to consider ketamine hydrochloride and several other drugs for scheduling under the Convention on Psychotropic Substances, a treaty established in 1971 as an international control system for the manufacture, distribution, transfer and use of drugs. How the WHOs scrutiny of ketamine might impact U.S. supplies - if at all - is unknown. In the United States, organized veterinary medicine has been on high alert for months given ketamines importance to animal health care. Ketamine has played a role in veterinary medicine for half a century as an anesthetic and adjunct to pain control, and it remains a critical drug in equine medicine. Regulators are taking a harder look at ketamine because its popularity as a recreational drug has increased worldwide, with China becoming the epicenter of global ketamine consumption and production, as reported by the BBC and other news media. Right now, the ...
Increasing preclinical and clinical evidence underscores the strong and rapid antidepressant properties of the glutamate-modulating NMDA receptor antagonist ketamine. Targeting the glutamatergic system might thus provide a novel molecular strategy for antidepressant treatment. Since glutamate is the most abundant and major excitatory neurotransmitter in the brain, pathophysiological changes in glutamatergic signaling are likely to affect neurobehavioral plasticity, information processing and large-scale changes in functional brain connectivity underlying certain symptoms of major depressive disorder. Using resting state functional magnetic resonance imaging (rsfMRI), the „dorsal nexus (DN) was recently identified as a bilateral dorsal medial prefrontal cortex region showing dramatically increased depression-associated functional connectivity with large portions of a cognitive control network (CCN), the default mode network (DMN), and a rostral affective network (AN). Hence, Sheline and ...
Unresolved inflammation underpins the pathogenesis of allergic airway diseases, such as asthma. Ketamine, accepted as a promising therapy for resistant asthma, has been demonstrated to attenuate allergic airway inflammation. However, the anti-inflammatory mechanism by ketamine in this setting is largely unknown. We aimed to investigate whether autophagy was involved in the protective effect of ketamine on allergic airway inflammation. Female C57BL/6 mice were sensitized to ovalbumin (OVA) and treated with ketamine at 25, 50, or 100 mg/kg prior to OVA challenge. In this model, the pulmonary morphological findings and airway inflammation were significantly inhibited at 50 mg/kg but not at 25 or 100 mg/kg. Moreover, 50 mg/kg ketamine abrogated the increased concentrations of inflammatory cytokines in bronchoalveolar lavage fluid (BALF) of allergic mice, as well as activated the expression of phosphorylated mammalian target of rapamycin (p-MTOR) and inhibited autophagy in

AbstractIt has been suggested that ketamine cause injury during developing brain. Minocycline could prevent neuronal cell death through the activation of cell survival signals and the inhibition of apoptotic signals in models of neurodegenerative diseases. Here we investigated the protective effect of minocycline against ketamine-induced injury in neural stem cell(NSC) from neonatal rat. Ketamine (100μM/L) significantly inhibited NSC proliferation, promoted their differentiation into astrocytes and suppressed neuronal differentiation of NSCs. Moreover, the apoptotic level was increased following ketamine exposure. Minocycline pretreatment greatly enhanced cell viability, decreased caspase-3-like activity, even reversed the differentiation changes caused by ketamine. To elucidate a possible mechanism of minocycline neuroprotective effect, we investigated the phosphoinositide3- kinase pathway using LY294002, a specific PI3K inhibitor. Immunoblotting revealed that minocycline enhanced the phosphorylation

While it can sometimes take weeks for the effects of antidepressant treatments to appear, intravenous ketamine can produce antidepressant effects in as little as two hours. However, ketamines effects fade after three to five days. New animal research by Chi-Tso Chiu et al. explores whether adding lithium to ketamine treatment can produce more sustained antidepressant effects.. Mice who are restrained by being placed in a tube for several hours (chronic restraint stress) exhibit a behavioral and neurochemical profile that resembles human depression. When Chiu and colleagues pretreated these stressed mice with sub-therapeutic doses of lithium (600 mg/L) in their drinking water for several weeks, a sub-therapeutic dose of ketamine (2.5 mg/kg of body weight) was enough to produce robust antidepressant effects in the mice, while neither drug alone was effective at these doses.. The combination of ketamine and lithium also restored the density of spines on the dendrites of neurons in the medial ...
Patients in palliative care need rapid-acting pharmacological options for psychological distress. N-methyl-D-aspartate antagonist ketamine is known to have a fast onset of anti-depressant and anxiolytic action. Its S-enantiomer S-ketamine (or esketamine) is an analgesic used as a routine treatment for refractory pain as an intravenous infusion (0.25 mg/kg over 45 min). This study investigates whether S-ketamine pain therapy has a positive impact on psychological distress caused by anxiety and depression in palliative care. Patient routine data from a palliative care unit of a tertiary care hospital were used in a retrospective analysis after positive ethics approval. Eight patients, who received analgesic S-ketamine treatment, were compared to a control group matched by gender and age. The main analysis was conducted using three-way mixed MANOVA followed by two-way mixed ANOVA. Target variables were the values for anxiety and depression in the state-trait anxiety-depression inventory STADI. The

A 2017 series of articles by researcher Chittaranjan Andrade in the Journal of Clinical Psychiatry reviews the last 10 years of research on ketamine, the anesthetic drug that in smaller doses (0.5 mg/kg of body weight) can bring about rapid antidepressant effects. Ketamine is typically delivered intravenously (though it can also be delivered via inhaler, injected under the skin or into muscles, and least effectively by mouth). Ketamine can improve depression in less than an hour, but its effects usually fade within 3 to 5 days. Repeating infusions every few days can extend ketamines efficacy for weeks or months.. Andrade cited a 2016 meta-analysis of nine ketamine studies by T. Kishimoto and colleagues in the journal Psychological Research. The meta-analysis found that compared to placebo, ketamine improved depression beginning 40 minutes after IV administration. Its effects peaked at day 1 and were gone 10-12 days later. Remission rates were better than placebo starting after 80 minutes and ...

It has also been used in human medicine for paediatric burn cases and dentistry, and in experimental psychotherapy. It is being abused by an increasing number of young people as a club drug, and is often distributed at raves and parties.
Background Low-dose ketamine has been shown to exert analgesic effects. Whether ketamine-induced pain relief may be quantitated by somatosensory evoked cerebral potentials has not been established. Methods Thirty healthy volunteers were assigned randomly to one of three groups. Subjects of group 1 (n = 10, control) were given saline as placebo. In groups 2 (n = 10) and 3 (n = 10), intravenous ketamine (0.25 mg. kg-1 and 0.50 mg. kg-1, respectively) was administered. The following variables were recorded at baseline and for 50 min after drug administration: electroencephalographic (EEG) data, somatosensory-evoked late cortical responses (SEP) elicited by intracutaneous stimulation of the fingertip (2-3 fold pain threshold), heart rate, mean arterial blood pressure, and end-tidal PETCO2 via a tight-fitting mask. Electroencephalographic spectral power in selected frequency bands and frequency percentiles were calculated from the spontaneous EEG segment preceding each somatosensory stimulus. ...
The induction of mTOR signalling suggests that the ability of ketamine to increase synaptogenesis is mediated by stimulation of this protein synthesis regulatory pathway. To directly test this hypothesis, the influence of rapamycin, a selective inhibitor of mTOR (figure 3), on synaptogenesis was examined. Rapamycin pretreatment completely blocked ketamine-induction of spine number and function of layer V pyramidal neurons in the PFC [42]. In addition, rapamycin pretreatment completely blocked the induction of the synaptic proteins PSD95, GluR1 and synapsin I, resulting from ketamine administration. These findings provide direct evidence that ketamine-induction of synaptogenesis requires mTOR signalling and synaptic protein synthesis.. Next, studies were conducted to determine whether the behavioural actions of ketamine are also dependent on mTOR signalling. Pretreatment with rapamycin completely blocked the antidepressant effects of ketamine in the FST, LH and NSF test [42]. Moreover, the rapid ...
N-methyl- D-aspartate (NMDA) receptors are involved in the development of central sensitization associated with chronic refractory pain syndromes. NMDA antagonists may modulate the CNS function, offering a novel approach to the treatment of chronic pain. Some studies suggest that ketamine, administered by intravenous infusion or orally, may be effective in relieving pain. However, intravenous ketamine may induce serious side effects such as vivid hallucination and psychosis. Recent reports suggest low dose ketamine may offer effective pain relief with remarkably few side effects.. ...
UT Southwestern Medical Center scientists have identified a key protein that helps trigger ketamines rapid antidepressant effects in the brain, a crucial step to developing alternative treatments to the controversial drug being dispensed in a growing number of clinics across the country.
Ketamine Infusion Therapy is NOT a first-line treatment for chronic pain. However, it is very effective in patients who arent getting enough relief from their current treatment approaches, or who wish to reduce their opioid intake.
Researchers implanted prisms in mouse brains to watch how ketamine affects neurons. The findings could lead to more effective antidepressant treatments.
TY - JOUR. T1 - Ketamine for analgosedation in critically ill patients. AU - Erstad, Brian L. AU - Patanwala, Asad E. PY - 2016/10/1. Y1 - 2016/10/1. N2 - Purpose The purpose of this narrative review is to provide practical and useful guidance for clinicians considering the use of intravenous ketamine for its analgosedative properties in adult, critically ill patients. Methods MEDLINE was searched from inception until January 2016. Articles related to the pharmacological properties of ketamine were retrieved. Information pertaining to pharmacology, pharmacokinetics, dosing regimens, adverse effects, and outcomes was obtained from relevant studies. Results Although the primary mechanism for ketamines pharmacological effects is N-methyl-D-aspartate blockade, there are several potential mechanisms of action. It has a very large volume of distribution due to its lipophilicity, which can lead to drug accumulation with sustained infusions. Ketamine has several advantages compared with conventional ...
A study confirms the antidepressant effects of intravenous ketamine at the standard 0.5 mg/kg dose and hints that a lower dose might also have some benefit with fewer side effects.
Preparation of the animals. A total of 45 adult Sprague Dawley rats of both sexes, weighing from 250 to 400 gm, were used in the present study. All surgical and animal care procedures adhered to the guidelines for the use and care of experimental animals of the Canadian Council of Animal Care. The Animal Care Committee of Laval University also approved our experimental protocol. The animals were first anesthetized with a solution of 10 cc ketamine hydrochloride (100 mg/ml) plus 1.5 cc xylazine (100 mg/ml) administrated intramuscularly (0.1 cc solution per 100 gm body weight). A local anesthetic (Xylocaine 2% or Marcaine 0.75%) was also administrated in the ears and forehead of the rats before their heads were placed in a stereotaxic apparatus (David Kopf Instruments, Tujunga, CA). The anterograde tracer biotin dextran amine (BDA) (Molecular Probes, Eugene, OR) was injected bilaterally in the dorsal or ventral tier of the SNc, the VTA, or the RRF using the stereotaxic coordinates of the atlas of ...

Even if severe hypoxia/ischemia did occur, it could not account for the neuroapoptosis response to ketamine because 4-6 h after ketamine administration, an increase in apoptotic profiles is evident both as a caspase-3 activation response and as ultrastructurally confirmed apoptotic morphology. However, when one intentionally induces hypoxia/ischemia and examines the developing brain 4-6 h later, there is no increase in apoptotic profiles, either by caspase-3 activation or ultrastructural criteria. It is illogical to argue that anesthesia-induced apoptosis is caused by hypoxia/ischemia if one cannot demonstrate that intentionally induced hypoxia/ischemia reproduces the anesthesia-induced apoptosis phenomenon. What one does find in the brain 4-6 h after hypoxia/ischemia, as we have demonstrated previously,3 and also very recently,4 is excitotoxic neurodegeneration. (See Young et al. 4 for a detailed presentation of evidence directly addressing and clarifying this issue.) Soriano et al. challenge ...
Commence infusion at 1ml/hr (60mcg/kg/hr) and increase by 1ml/hr every 6hours until a maximum dose of 4ml/hr (240 mcg/kg/hr) is reached. The maximum rate should be achieved by 18 hours from commencing infusion.. If the child has difficulty tolerating the increased rate changes at 6 hourly intervals this can be extended to 12 hour intervals, this decision will be made by the complex pain service. If the child is unable to tolerate 12 hour interval increases then the rate is maintained at the highest tolerable dose.. If the child shows a reasonable response from a lower rate than the recommended maximum of 4ml/hr, then the infusion is maintained at this lower dose. This decision will be made by the complex pain service.. ...

Results of this study show ketamine acts on the mu, kappa, and delta opioid receptors as an agonist (we already know ketamine acts on the NMDA receptor as an antagonist). The study conclusion shows that activation of the opioid receptors by ketamine is necessary for its antidepressant effects. The study proved the above findings by administering study patienst naltrexone (an opioid receptor antagonist) prior to the administration of IV ketamine therapy. Those subjects that received naltrexone prior to receiving the IV ketamine infusion therapy showed decreased effects of the ketamine on depressive symptoms.. Read More ...

TY - JOUR. T1 - Initial experience with iv ketamine infusion for treatment of post sternotomy pain in a patient with a total artificial heart. AU - Maher, Dermot P.. AU - Loyferman, Rusty. AU - Yumul, Roya. AU - Louy, Charles. PY - 2015/1/1. Y1 - 2015/1/1. N2 - The implantation of total artificial hearts (TAHs) via midline sternotomy for the treatment of severe biventricular cardiac dysfunction is associated with complex postoperative pain management. Ketamaine increases blood pressure by raising sympathetic outflow and cardiac ouput; however, ketamine is a direct vasodilator on isolated arterial tissues. In the setting of a TAH with a mechanically fixed cardiac output, a ketamine infusion for postoperative pain control has the potential to decrease blood pressure due to direct arterial vasodilation. We present the initial experience with a ketamine infusion in a patient with a TAH with minimal observed decreases in blood pressure and significantly improved postoperative pain.. AB - The ...
Acute pain management in the emergency department with low-dose ketamine may provide pain relief comparable with morphine at 30 minutes.
Drugs such as phencyclidine (PCP) and ketamine (Special K) were developed as general anesthetics. They produce distortions in both sight and sound and a general feeling of detachment (you feel far away from your body). Dextromethorphan, a widely available cough suppressant, when taken in high doses, can produce effects similar to PCP and ketamine. Nitrous oxide, sometimes known as laughing gas, is also a member of this same category of substances.. PCP, ketamine, and dextromethorphan work by preventing a neurotransmitter, glutamate, from attaching to its receptors in the brain. Glutamate is involved in the perception of pain, responses to the environment, and memory. Although low doses of the anesthetics increase heart rate, higher doses can depress consciousness and breathing. Combining this category of substances with alcohol or other sedatives is extremely dangerous.. These dissociative anesthetics carry the risk of extreme psychological dependence. They separate your perceptions from ...
Our own clinical experience has been that many patients referred to our clinic have been on an SSRI for prolonged periods with little or no impact on their symptoms, and this has led us to investigate other potential pharmacotherapies, in particular the anticonvulsant lamotrigine. Lamotrigine acts at the presynaptic membrane to reduce the release of glutamate, and it has been shown to reverse depersonalisation-related phenomena induced by the N-methyl-d-aspartate (NMDA) receptor antagonist ketamine in healthy individuals (Anand et al, 2000). In the absence of large-scale randomised controlled trials, and in the presence of conflicting published data (see below), the efficacy of lamotrigine (whether as monotherapy or in conjunction with an SSRI) is not yet firmly established, but it is often our first-line treatment for the condition.. An initial study of lamotrigine monotherapy in four patients with primary depersonalisation found substantial benefits in all cases (Sierra et al, 2001), but a ...
Traditional medications merely dull pain signals in the brain. Low-dose Ketamine Infusions actually reboots your neurotransmitters. Immediate and sustained relief from chronic pain is possible.
Schizophrenia patients are waiting for a treatment free of detrimental effects. Psychotic disorders are devastating mental illnesses associated with dysfunctional brain networks. Ongoing brain network gamma frequency (30-80 Hz) oscillations, naturally implicated in integrative function, are excessively amplified during hallucinations, in at-risk mental states for psychosis and first-episode psychosis. So, gamma oscillations represent a bioelectrical marker for cerebral network disorders with prognostic and therapeutic potential. They accompany sensorimotor and cognitive deficits already present in prodromal schizophrenia. Abnormally amplified gamma oscillations are reproduced in the corticothalamic systems of healthy humans and rodents after a single systemic administration, at a psychotomimetic dose, of the glutamate N-methyl-d-aspartate receptor antagonist ketamine. These translational ketamine models of prodromal schizophrenia are thus promising to work out a preventive noninvasive treatment against

Purpose: Determine the stability of fentanyl 10 mcg/mL in 0.9% sodium chloride, fentanyl 10 mcg/mL in 5% dextrose, fentanyl 50 mcg/mL, hydromorphone 100 mcg/mL in 0.9% sodium chloride, ketamine 10 mg/mL, midazolam 0.4 mg/mL in 5% dextrose, midazolam 5 mg/mL, morphine 1 mg/mL in 0.9% sodium chloride, morphine 1 mg/mL in 5% dextrose, and pentobarbital 50 mg/mL when stored as single drug entities at room temperature in polypropylene syringes. Methods: Four 5 mL samples of each drug and concentration were prepared in 10 mL polypropylene syringes. The samples were stored at ambient room temperature in a locked cabinet. Triplicate determinations of drug concentration for each sample were performed initially, on day 50 or 51, and on day 100 using high-performance liquid chromatography with diode-array detection. Results: With the exception of the hydromorphone 100 mcg/mL dilution, all compounds were found to contain greater than 95% of their initial concentration remaining at 100 days. Each sample remained
To assess the prevalence of intraoperative penile erection in our endourology practice and the utility of intravenous ketamine in the management of the condition. Of 402 endoscopic urological procedures performed in our clinic over a 4-year (2015-2019) period, a total of 9 cases with intraoperative penile erection impeding instrumentation during endourological surgery were included. Data on patient age, weight, height, American Society of Anesthesiologists (ASA) physical status classification system scores, type and duration of surgery, type and level of anesthesia, onset of erection, treatment characteristics and treatment outcome were recorded for each patient. The mean (SD) age was 68.3 years (range, 66.0-77.0 years). ASA physical status category I and II were noted in 55.6 and 44.4% of patients, respectively. All cases received spinal anesthesia (n = 9) at T8-10 dermatome levels, for TURP in 7 (77.8%) cases and for TURBT in 2 (22.2%) cases. The onset of penile erection was post-urethroscope in 7 (77
N-methyl-D-aspartate (NMDA) receptor antagonists administered to healthy humans results in schizophrenia-like symptoms, which preclinical research suggests are due to glutamatergically altered brain oscillations. Here, we examined resting-state electroencephalographic activity in 21 healthy volunteers assessed in a placebo-controlled, double-blind, randomized study involving administration of either a saline infusion or a sub-anesthetic dose of ketamine, an NMDA receptor antagonist. Frequency-specific current source density (CSD) was assessed at sensor-level and source-level using eLORETA within regions of interest of a triple network model of schizophrenia (this model posits a dysfunctional switching between large-scale Default Mode and Central Executive networks by the monitor-controlling Salience Network). These CSDs were measured in each session along with subjective symptoms as indexed with the Clinician Administered Dissociative States Scale. Ketamine-induced CSD reductions in slow (delta/theta
Because posttraumatic tension disorder (PTSD) is an extremely debilitating condition, prevention can be an important analysis topic. personnel that were treated for serious burns uncovered that those sufferers who acquired received the dissociative anesthetic ketamine during medical procedures had considerably lower prices of PTSD than those that hadnt, although their accidents had 49671-76-3 IC50 been more serious than those from the control group. Within this research, no relationship between PTSD and morphine similar units during functions was noticed [27]. Again, such as opioids, the pharmacological ramifications of ketamine (e.g., hallucinations and psychomotor retardation) make it unsuitable for principal avoidance. Although antidepressants will be the most commonly utilized medications to take care of the symptoms of PTSD, the data for feasible secondary as well as principal precautionary effects is normally scarce [28]. Tests on benzodiazepines, a course of medications that could cause ...
Narconon Drug Rehab in Georgia warns that ketamine abuse can have deadly effects.. We have seen many cases where ketamine, or Special K, has been abused by teens because of its hallucinogenic effect, comments Mary Rieser, Executive Director.. What many teens dont realize is that Ketamine can be very addictive and can cause death.. Ketamine can be purchased on the internet, so be aware of your childs internet activity. dont let them become another Ketamine casualty. Ketamine is a rapidly acting general anesthetic. Its pharmacological profile is essentially the same as phencyclidine. Like PCP, ketamine is referred to as a dissociative anesthetic because patients feel detached or disconnected from their pain and environment when anesthetized with this drug. Unlike most anesthetics, ketamine produces only mild respiratory depression and appears to stimulate, not depress, the cardiovascular system. In addition, ketamine has both analgesic and amnesic properties and is associated with less ...
I am grateful for the opportunity to share our experience with Kalypso, in particular, with Laney who runs The Woodlands clinic. To us, Laney IS Kalypso. To begin with, Laney creates an environment upfront that causes the patient and his/her caregivers to feel at ease. Laney is confident about what Kalypso has to to offer and she relays that confidence to others. She is realistic as well as thorough in the way she explains the Ketamine treatments. And she delivers. Laney listens intently to the patient to determine, along with the consent of the patient, what the makeup of the infusion needs to be. Her knowledge of the contents of each infusion is outstanding! Outstanding! She is sensitive to the progress of the patient as to whether any adjustments may or may not need to be made. BTW, regarding follow-up with the patient: LANEY takes the initative to follow up by text or phone call bc she genuinely wants to know the degree to which the specialized ketamine infusion has effected the patient. ...

Exposure of urothelium to ketamine resulted in apoptosis, with cytochrome c release from mitochondria and significant subsequent caspase 9 and 3/7 activation. The anaesthetic mode‐of‐action for ketamine is mediated primarily through N‐methyl Daspartate receptor (NMDAR) antagonism; however, NHU cells were unresponsive to NMDAR agonists or antagonists and no expression of NMDAR transcript was detected. Exposure to non‐cytotoxic concentrations of ketamine (≤1 mM) induced rapid release of ATP, which activated purinergic P2Y receptors and stimulated the inositol trisphosphate receptor to provoke transient release of calcium from the endoplasmic reticulum into the cytosol. Ketamine concentrations ,1 mM were cytotoxic and provoked a largeramplitude increase in cytosolic [Ca2+] that was unresolved. The sustained elevation in cytosolic [Ca2+] was associated with pathological mitochondrial oxygen consumption and ATP deficiency ...

Repost from the old site.. At the time I was into getting high, roughly 1973-1988, there wasnt a lot of good information that most of that stuff was bad for you, or certainly that it was bad for your brain. There was a lot of information that said that drugs could be used recreationally in moderation without problems. That was the spirit of the age. Its dead and gone now, maybe forever.. I keep thinking that if I knew then what I know now, I would not have gotten into drugs as much as I did. The drugs all seem so much worse now because our information is greater. My use was really a product of an era as opposed to just some general degenerate tendency of mine.. Cocaine.. Towards the end of the period, cocaine had turned from the Yuppie Party Drug into the Evillest Drug of Them All.

We still thought we could use the ...

A 28-year-old woman presented to us in November 2010 because of deranged liver function test results; predominantly she had raised ductal enzyme levels (gamma-glutamyl transferase, 1088; reference range, 12-57 IU/mL); alkaline phosphatase (ALP) 579 (reference range, 46-127) IU/mL, alanine transaminase (ALT) 183 (reference range, 10-57) IU/mL with normal bilirubin levels. Upon further questioning, she had been a ketamine abuser for 5 years and was followed up by psychiatrists. She was completely asymptomatic and physical examination yielded nil abnormal. Her ALP level was excessive (154 IU/mL) and her ALT level was 48 IU/mL. Ultrasound of hepatobiliary system (HBS) showed a dilated common bile duct (CBD) of 1.1 cm in diameter with tapering over lower end. A gallstone was present in the gallbladder. Therefore, the endoscopic retrograde cholangiopancreatography (ERCP) was performed in November 2011, and showed a 5-cm stricture at the lower end of the CBD together with small bilateral segmental ...
The present study was assigned to evaluate and compare two regimes of general anesthesia in rabbits. Twelve adult local breed rabbits from both sexes weighing (1.1-1.6( Kg. were divided equally into two groups each group consisted of six animals. Group(A) was injected intramuscularly by atropine1% at a dose 0.5mg/kg B.W as premedication, after 10min. the animals were injected xylazine 2% and ketamine hydrochloride 10% at a dose of 10 mg/kg, 50mg/kg B.W, respectively. Group(B) were injected intramuscularly by diazepam 10% at a dose 1mg/kg B.W. as premedication, after 10min. the animals were injected as same in group (A). The results of the physiological parameters of the self control at the period of zero time concerning heart rate, respiratory rate and rectal body temperature in group(A) were 147.3±0.577beats/minute; 130±0.577 breath/minute; 38.1±0.577 ºC respectively, while in group(B) were 151.6±0.57 beats/minute; 153.3±0.57 breath/minute; 38±0.57 ºC respectively.

Like Ketamine treatments for bipolar and autism, Ketamines ability to target the glutamatergic transmission (the excitable impulses) in the brain is exactly what makes Ketamine such an effective alternative. While most traditional medications treat for dopamine, that model does not often work (in fact, it doesnt for the majority of people struggling with serious mental health difficulties). For schizophrenic patients, this is very good news. Ketamine is able to greatly help schizophrenic patients needing improved sensory processing and higher-level functions, like memory, far better than traditional medication. In addition to this good news, according to Dr. Joshua T. Kantowitz, Ketamine has great potential in not only treating schizophrenia, but also helping doctors understand schizophrenia better.. However, unlike for bipolar and autism, Ketamine therapy isnt as straightforward when treating schizophrenia. Because of the long list of schizophrenia symptoms, its important that both the ...

With ketamine anesthesia in cats, reflexes such as palpebral, gag, etc. tend to be preserved even at surgical planes of anesthesia.

Ketamine is an N-methyl-d-aspartate receptor antagonist, a dissociative anaesthetic agent and a treatment option for major depression, treatment-resistant depression, and bipolar disorder. Its strong psychostimulant properties and easy absorption make it a favourable candidate for substance abuse. Ketamine entered Hong Kong as a club drug in 2000 and the first local report of ketamine-associated urinary cystitis was published in 2007. Ketamine-associated lower-urinary tract symptoms include frequency, urgency, nocturia, dysuria, urge incontinence, and occasionally painful haematuria. The exact prevalence of ketamine-associated urinary cystitis is difficult to assess because the abuse itself and many of the associated symptoms often go unnoticed until a very late stage. Additionally, upper-urinary tract pathology, such as hydronephrosis, and other complications involving neuropsychiatric, hepatobiliary, and gastrointestinal systems have also been reported. Gradual improvement can be expected ...
Ventilation according to the open lung concept (OLC) consists of recruitment maneuvers, followed by low tidal volume and high positive end-expiratory pressure, aiming at minimizing atelectasis. The minimization of atelectasis reduces the right ventricular (RV) afterload, but the increased intrathoracic pressures used by OLC ventilation could increase the RV afterload. We hypothesize that when atelectasis is minimized by OLC ventilation, cardiac function is not affected despite the higher mean airway pressure. After repeated lung lavage, each pig (n = 10) was conventionally ventilated and was ventilated according to OLC in a randomized cross-over setting. Conventional mechanical ventilation (CMV) consisted of volume-controlled ventilation with 5 cmH2O positive end-expiratory pressure and a tidal volume of 8-10 ml/kg. No recruitment maneuvers were performed. During OLC ventilation, recruitment maneuvers were applied until PaO2/FiO2 > 60 kPa. The peak inspiratory pressure was set to obtain a tidal volume
Palavras-chave: neoplasia, cirurgia, canídeos selvagens.. ABSTRACT. It is reported a case of cutaneous papillomatosis in a six-year old, male Bush Dog (Speothus venaticus), from the Zoo of Curitiba, Paraná, Brazil. The patient was submitted to general anesthesia with the association of ketamine hydrochloride, xylazine hydrochloride and atropine sulfate, for routine clinical examination. There were found tumors in both sides of the face, mostly around the nostrils, on the lips, and under the right eye. They measured 0.4 to 2.0 cm in diameter and up to 0.5 cm in height, and were surgically removed. Samples were collected and microscopically examined.Histologically, epidermis showed irregular endophytic and exophytic hyperplasia with short and irregular papilliform formations, as well as compact orthokeratosis. The epidermal granulous layer showed irregular and coarse granules of queratohyalin, suggesting a viral etiology.The proliferative keratinocytes did not show significant signs of atypia, ...
The piglets from which samples have been taken included animals from different ages, as early as 1 day old. Administer a combination of 2 mL Xylazine (Rompum(R) 100 mg per mL) mixed in a 10-mL bottle of Ketamine hydrochloride (Ketaset(R) 100 mg per mL) intramuscularly to small piglets (1-15 days old) at a dose between 0.1 mL to 0.3 mL, according to their size. After 10 minutes, place the pig in a sitting position, extending the neck toward the front in order to facilitate visualization of the internal structures. After gently retracting the tongue, introduce a laryngoscope (Jorvet 80 mm blade) into the oropharyngeal cavity. Position the tube above the tip of the epiglottis as the reference point for the intubation.

Pinpointing the volume of malpractice promises relevant to the usage of reasonable sedation is tough. It has been estimated that close to a person in just about every five hundred malpractice statements requires complications linked to endoscopic sedation [27]. (Knowledge on promises connected to sedation from the unexpected emergency Division setting are usually not readily available.) Prospective legal challenges relevant to reasonable sedation are related to a failure to administer sedation in accordance with the common of treatment, failure to obtain ideal knowledgeable consent, as well as the patients discharge position [27,124]. Moreover, affected person expectation of agony-cost-free methods may perhaps raise the risk of malpractice statements for two good reasons: people statements of insufficient sedation, and oversedation as a method to be sure a ache-free standing [27 ...
Ketamine, typically thought of as an anesthesia medicine or even a club drug, is now generating a lot of interest among pain management specialists as a useful approach to hard-to-treat migraines and chronic pain.
Stephen E. Lankenau, PhD, Mailman School of Public Health, Columbia University, 722 W. 168th St., Suite 1040, New York, NY 10032, 212-305-5736, [email protected] Parochially known as Special K, Vitamin K, or simply K, ketamine is a conger of phencyclidine (PCP). Used for many years as an anesthetic in emergency and veterinary medicine, ketamine has recently emerged in a non-clinical context as one of several synthetic substances classified as club drugs. Like other so-called club drugs, such as MDMA, GHB, and Methamphetamine, most available information about ketamine stems from studies focused on club drug environments and populations, notably MSM venues. Much of this data has presumed non-injected modes of administrating ketamine, and HIV risk has been assessed in relation to increased risk for sexual transmission. Recent ethnographic data from New York indicates the previously unrecognized use of injection as a mode of administration ketamine - a practice that is prevalent among ...
