Was supplemented by 500 U every 20 minutes. The venous effluent dripped into a small reservoir, which drained into the right atrium via a large silicon rubber catheter previously placed through the right external jugular vein. Volumetric flow measurements were obtained by collecting timed samples of sagittal sinus blood in a plastic tuberculin 1 ml ; syringe. Cerebrovascular reactivity was assessed by measuring CBF before and during CO2 inhalation for 2 minutes at an ETCO2 of 8%. The experiments were continued only when CBF increased by 50%. CBF and O2 consumption measurements were taken before and 2-4 minutes after the i. v. injection of ketamine Ketalar, Parke-Davis, 1 mg kg ; , and only after the EEG displayed a characteristic high-voltage, lowfrequency pattern, 1213 which corresponded to the highest steady flow observed in our pilot studies and previous reports." GROUP 2. CBF was measured in 5 animals with a H2 clearance technique that allowed flow recording and sampling without heparinizing the rabbit. The sagittal sinus was exposed as described for Group 1, and an insulated platinum electrode 75 fim diameter, 0.5 mm bare tip ; held in a micromanipulator was advanced into the sinus via a 26-gauge needle hole. A 20-gauge 1 lA inch Teflon cannula Angiocath, Deseret ; was inserted through the confluens and advanced with a micromanipulator until its tip was just dorsal to the implanted electrode. This size of cannula was chosen as it allowed free flow of blood around the cannula. The cannula was flushed with a heparin-saline solution 2 U ml ; rate of 0.1 ml 10 min. CBF was calculated in ml 100 g min using the H2 clearance technique described by Aukland et al14 and Aukland13 as previously used in rabbits.1011 Five percent H2 was added to the inspired gas mixture until the H2 polarographic current between the platinum electrode in the sinus and a distant subcutaneous Ag-AgCl electrode reached a sustained plateau for 3 minutes. H2 inflow was then stopped, and the H2 concentration H2 current ; was continuously recorded during the whole desaturation period until the H2 current returned to baseline. The calculation was based on the expression K 100 X In2 X Tfc, where K is the blood flow and Tvi is the half-time of the washout slope in minutes. 1416 The half-time was taken at between 60 and 30% of the plateau H2 current. Previous observations10 indicated that during this interval, the arterial H2 concentration was negligible and the slope was monoexponential. Arterial and sagittal sinus blood samples were collected half-way during the H2 washout period. The effect of ketamine was studied after a control clearance was measured. Ketaminr 1 mg kg ; was injected after the H2 current reached and maintained a second steady level for 3 minutes. Two to four minutes after the injection of ketamine, H2 inflow was stopped and arterial and venous samples were again taken. This approach, based on our observations with volumetric flow measurement and the findings of Reicher et al, 9 allowed estimation of the highest blood flow, which peaks at 2-4 minutes and remains at this level for. Ten healthy volunteers seven men and three women; mean age 35.2 years, SD 9.2 ; participated in this study. The subjects were in good health and underwent a brief medical evaluation. The subjects were free of psychiatric disorders on clinical examination and on the Structured Clinical Interview for DSM-III-R 19 ; . All of these subjects had been drug- and alcohol-free for at least 6 months, and all concurrently participated in a separate study examining the effects of ketamine on healthy volunteers. Fifteen patients 10 men and five women; mean age 33.4 years, SD 9.5 ; who met the DSM-IV criteria for schizophrenia N 14 ; or schizoaffective disorder N 1 ; were admitted to the 4th Floor East Patient Care Unit of the National Institutes of Health NIH ; Clinical Center in Bethesda, Md., or the Neurosciences Center of NIH at St. Elizabeths Hospital in Washington, D.C. Two patients were free of antipsychotic drugs, and 13 patients were undergoing pharmacotherapy during the rating period. Antipsychotic drug treatment was with olanzapine N 6 ; , clozapine N 2 ; , risperidone N 3 ; , and fluphenazine N 2 ; . All patients were clinically stable but symptomatic at the time of assessment. The healthy volunteers and patients with schizophrenia were gender- and age-matched age differences: t 0.47, df 23, p 0.64 ; . After a complete description of the study to the subjects, written informed consent was obtained. Ketamune was administered as a bolus followed by constant infusion over 1 hour to the healthy volunteers in a double-blind, placebo-controlled fashion, as previously described 6, 7, 10 ; . Formal thought disorder was rated using the Scale for the Assessment of Thought, Language, and Communication to assess specific aspects of thought disorder during a 15-minute interview. Healthy volunteers were rated during infusions of ketamine and placebo. Ratings were conducted by a single experienced investigator C.M.A. ; . To compare ketamine-induced thought disorder with thought disorder in patients with schizophrenia, independent t tests two-tailed ; were conducted with the scores from the Scale for the Assessment of Thought, Language, and Communication obtained from the patients with schizophrenia and the scores obtained from the healthy volunteers during ketamine infusions. Scores from the Scale for the Assessment of Thought, Language, and Communication were analyzed in. 68. Binschadler, D. D., and Bennett, J.

Antagonist. In the current study picrotoxin restored the amplitude of inspiratory activity depressed by ketamine and reduced an apneustic prolongation of the inspiratory phase. Picrotoxin eliminated the ketamine-induced prolongation of STD of and shortened but it even on more to the level comparable with the control condition. This means that picrotoxin acts not only on the GABA-ergic properties ketamine also other inhibitory mechanisms activated by sustained stimulation of the vagus nerve. V agal stimulation evokes inhibitory post-synaptic potential IPSP ; in inspiratory neurons in the ventral respiratory group 9 ; . This medullary region sets the intensity of the inspiratory activity 10 ; . NMDA receptors seem not involved in IPSPs, while GABA antagonism depresses them. Picrotoxin augments post-synaptic neuronal excitability and increases the efficacy of excitatory synaptic inputs 11 ; , which may increase the initial amplitude of and lanoxin.

93 either exteroceptive stabbing, burning ; or proprioceptive squeezing, cramp-like ; in nature. It can be continuous or intermittent, and its intensity may be mild to excruciating. Phantom sensations, stump pain, and PLP are closely associated. PLP usually is less severe in amputees without phantom sensations or stump pain24, 25. It seems to be less likely if the initial amputation is treated actively and a prosthesis promptly used26. A recent survey in 590 ex-servicemen found that PLP persisted in 47% of the amputees, disappeared in 16%, and required treatment in 55%. In this survey PLP was so severe VAS 8.7 ; in 25% that they sought pain consultation. A large, older military survey found nearly identical figures25. Predisposing factors. Age, site of amputation, or preamputation pain intensity seem not to influence the persistence of late 6 months ; PLP20, 2325, 27. No conclusive data link the type of anesthetic used during amputation and the incidence of PLP. Despite earlier claims28, 29, a well-controlled, randomized trial did not show a reduction in the incidence of PLP by preemptive epidural analgesia30. This question is important as preamputation epidural analgesia is not without risk. The study did, however, show that active pain control decreased the incidence and severity of chronic pain problems. Treatment. Treatments must reflect solid clinical experience or experimental evidence. No single form of treatment claims success19. Recently it has been suggested that transcutaneous electrical nerve stimulation TENS ; , paracetamol with or without a weak opioid ; , and nonsteroidal anti-inflammatory drugs NSAIDs ; are more effective for PLP than injections, "centrally acting" analgesics like tricyclics or anticonvulsants, and strong opioids24. Simpler methods of pain relief appear to be more effective and are more accessible in countries with landmine problems. Clinical experience31 and that of the voluntary agency Douleur Sans Frontires in the developing world suggests that neurolytic blockade of neuromas may reduce stump pain and that TENS can reduce PLP32. Evidence for efficacy of second-line therapies for PLP usually is based on small numbers and limited follow-up3339. These treatments include calcitonin, beta-blockers, neuroleptics, injection of local anesthetic drugs into the contralateral side, neurosurgery, and central stimulation. Other treatment methods may have been tried unsuccessfully and not reported, or not published owing to negative results. There is increased interest in the use of NMDA antagonists in chronic pain conditions even though side effects limit their current use. They may also have a place in the preemptive management of postamputation pain problems. The wide use of ketqmine in developing countries may yield data about the role of this NMDA antagonist to reduce PLP40, 41. Sympathetic blockade has been used diagnostically and therapeutically. However, neurolytic block normally requires radiologic control and its effect gradually wears off42. Discussion Those who produce and use armaments rarely consider their long-term effects upon health. From a military point of view landmines continue to be considered an effective weapon, due to their low cost and deterrent capabilities.

Children undergoing surgery of at least 30 minutes, it does not delay discharge from the PACU.21 Oral ketamune 3-10 mg kg-1 has been used successfully as a premedication in children. It preserves airway reflexes, but secretions, blood or gastric regurgitant can trigger laryngospasm. Ketamije stimulates the cardiovascular system, increasing heart rate and blood pressure. Finally, parents should be apprised of the appearance of the dissociative state produced by ketamine.2 and lescol.

PHYSICIAN PEARLS: DXM recreational doses typically range from 1.5-30 mg kg, with alcohol mimicking effects at 1.5 mg kg, hallucinations at about 2.5-3.0 mg kg, and disassociation occurring about 7.5-15 mg kg. Respiratory depression and or anesthesia risk increases from 15 mg kg upward, with anesthesia almost certain above 30 mg kg. Ketamine's recreational dosage varies, but anesthesia may occur as low as 1.5-2.0 mg kg. Histamine Release: DXM in particular may cause idiopathic histamine release hives, uticaria, etc ; commonly called the "Robo-Itch". In addition extra-pyramidal Symptoms may develop. Benadryl is an appropriate agent for both of these conditions. Spatial Disassociation: Commonly called the "Robo Walk" this is the result of mild disassociation and decrease in motor function most commonly seen in DXM. While not a problem per se, this does produce a fall hazard for the patient.

We have previously reported beneficial effects of thioperamide treatment in a rat model of inflammatory bowel disease. Here we present data on its influence on colonic haemodynamics. Colitis was induced in ketamine xylazine-anaesthetised rats by intracolonic administration of 2, 4, 6-trinitrobenzene sulfonic acid TNBS, 25mg in 0.8ml 37% ethanol ; . The animals were injected daily with thioperamide 2mg kg i.p. ; or saline. Controls received 0.8 ml of saline. At 5 and 7 days after TNBS rats underwent a midline laparotomy under urethane anaesthesia for haemodynamic measurements. Inferior mesenteric artery blood flow IMBF ; was measured using ultrasonic transit time technique Transit Time Flowmeter Type 700, electrode type 1RB2006, Hugo Sachs Elektronik, Germany ; . Macroscopic scoring of colonic damage was performed using a 10 point rating scale.Tissue and plasma histamine concentrations were measured by fluorimetric and radioenzymatic assays, respectively. There was increased IMBF at 5 and 7 day of colitis in both groups in comparison to the control. Interestingly, in thioperamide-treated rats, IMBF was significantly lower than in salinetreated animals at 7 day after induction of colitis 2.790.47 vs. 3.880.61ml min ; . Macroscopic damage score was significantly increased at 5 and 7 day of colitis in comparison to the control. There were no significant changes in mucosal damage between the two groups 5 days after TNBS installation, however, at 7 day, the scoring in thioperamide-treated was significantly lower than in saline-injected rats 4.33 vs. 6.66, P 0.013 ; . The colonic histamine concentrations were significantly decreased while plasma histamine levels were higher in TNBS-rats saline-treated compared to the thioperamide-treated ones. We conclude that histamine, acting via H3 H4 receptors, influences inferior mesenteric blood flow in TNBS-induced colitis. The study supports and extends our previous observations that thioperamide treatment accelerates healing processes in inflamed colon and levothroid.
