조남수,이경운,김용배 대한응급의학회 1996 대한응급의학회지 Vol.7 No.2

Our study was made on 96 cases of ketamine anesthesia, who visited to emergency department of Chosun university hospital. This patient was not controlled by verbal order and lidocaine anesthesia, and indication for the use of ketamine(from 1 to 5 years old). Dosage of ketamine in the intramuscular injection was 5mg/kg, in the intravenous injection was 2mg/kg. The results were as follows; 1. After the ketamine injected, expending time doing induction was for 2∼4 minutes in cases of intramuscular injection, and expending time doing induction was for 20∼60 seconds in cases of intravenous injection 2. After the ketamine injected, patient`s awake time was 50±5 minutes in case of intramuscular injection, and that is 20±5 minutes in cases of intravenous injection. 3. Injected ketamine caused increased blood pressure, pulse rate, and respiration rate, and saturation of oxygen was maintained 92-98% level. 4. In adverse effect, the presence of spontaneous eye opening, mild a groan, purposeless involuntary movement and increased excretion of saliva was appeared. 5. Advantage of ketamine injection was that one attendant was enough for restraining the patient, and reduced pain sense, and operator performed various procedures easily on stable condition. From the above results, it was considered in emergency department that indications for ketamine anesthesia are primary closure of simple facial laceration, burn dressing, and some diagnostic procedures( cardiac & ureteric catheterization, cystoscopy) in pediatric patients. It was considered, that all procedures should be performed under fullfill all the condition such as professional control devices(esp. central monitoring system) and basic CPR instruments and ketamine anesthesia-skilled doctor.

조규종,김원,최옥경,임경수 대한응급의학회 1999 대한응급의학회지 Vol.10 No.4

Backgrouds : Headache is one of the common symptoms complained by patients at the emergency department. Postural headache is the characteristic symptom that is aggravated at upright position and relieved at recumbent position. This postural headache is associated with low cerebrospinal fluid (CSF) pressure. Spontaneous intracranial hypotension(SIH) is an unusual syndrome of postural headache and low CSF pressure without a precipitating event. The diagnosis of SIH is confirmed by 60mmH2O or less CSF opening pressure on lumbar puncture. However, the cases of SIH with normal CSF opening pressure have been reported. so it is needed to complement the diagnostic criteria of SIH. Methods : A retrospective descriptive study with reviewing medical records of 10 patients who had been admitted at Asan Medical Center from Apr. 1995 to Jul. 1999 was done. Analyses were done of 22 variables of age, sex, clinical symptoms, spinal analysis findings, radiologic findings and therapeutic modality. Fisher's exact test and Mann-Whitney test were applied for statistical analysis (p-value < 0.05). Results ; 1. The male to female ratio was 3:7, and the mean age was 37.30±5.96 years. 2. Postural headache was characteristic symptom & complained by all patients. 3. The mean CSF pressure was 22.8±30.8 mmH2O. 4. Brain MRI demonstrated the pachymeningeal enhancement in all patients. 5. Radioisotope cisternography demonstrated slow ascent of tracer to the cerebral convexity in 88.9% patients, early soft tissue uptake suggestive of CSF leakage & rapid urinary accumulation of tracer in 66.7% patients, respectively. 6. 90.0% of all patients were recovered with autologous epidural blood patches, and 10.0% were recovered with conservative management. Conclusion : The SIH is an unusual syndrome. but we can diagnose the SIH in the patient, complains of a postural headache, if any following two or more criteria are present. 1. 60mmH2O or less CSF opening pressure on lumbar puncture. 2. Brain MRI finding : the pachymeningeal enhancement. 3. Cisternography findings : slow ascent of tracer to the cerebral convexity, early soft tissue uptake suggestive of CSF leakage & rapid urinary accumulation of tracer.

Background: Recently, a few studies demonstrated that melatonin reduced the severity of myocardial reperfusion injuries, such as reperfusion arrhythmias. However, it is uncertain whether the melatonin reduces reperfusion arrhythmias in thus anesthetized animals because results were obtained using isolated hearts. Thus, to see whether melatonin reduces reperfusion arrhythmias in anesthetized animals, we examined the effect of melatonin on the incidence of reperfusion arrhythmias in an anesthetized-cat model of regional ischemia. Method: Adult mongrel male cats(n=30, 2.9∼4.2 kg) were anesthetized under positive-pressure artificial ventilation with room air. The animals of the control group(n=15) were subjected to 20-minute left anterior descending coronary artery(LAD) occlusion followed by abrupt reperfusion. The animals in experimental group(n=15) were divided into two. Group I(n=6) was pretreated with melatonin, 1 mg/kg, before occluding the LAD. Group II(n=9) was pretreated with melatonin, 10 mg/kg. The animals in experimental group were subjected to ischemia/reperfusion insult following drug treatment: melatonin was applied intra-peritoneally for 3 minutes just before LAD coronary artery ligation. The Fisher's exact test was used to compare the data from different animal groups. p<0.05 was considered significant. Results: The incidence of ventricular fibrillation(VF) during the reperfusion phase in group II(pretreated with melatonin, 10 mg) was significantly smaller than that in the control group(p-value = 0.0029). However, no statistically significant difference of VF incidence was found between group I(pretreated with melatonin, 1 mg) and the control group. Conclusion: Employing an anesthetized-cat model of regional cardiac ischemia, we investigated the dose-dependant effects of melatonin on reperfusion-induced arrhythmia. The cats pretreated with 10 mg/kg of melatonin before ischemia had a significantly reduced incidence of lethal reperfusion-induced arrhythmia, but there was no difference between the cats pretreated with 1 mg/kg of melatonin before ischemia and the control group.

Background: Superior colliculus is a part of midbrain, and participates in the visual reflexes, It receives afferent fibers from optic nerve, visual cortex, and spinotectal tract. After optic deprivation, the microscopic structure of the superior colliculus changed. Calcium-binding proteins (CBPs) Play an important role in the neuronal protection, differentiation and reorganization of the central nervous system, Objectives and Methods: The effects of neonatal retinal deafferentation on a CBPs, calbindm D-28k (CB), Parvalbumin (PB) and calretimn (CR), and the existence of colocalization between the CBPs were examined immunohistochemically in the rat superior colliculus. Results: On the experimental (contralateral to enucleation) side of superior colliculus, the number of CB-immunoreactive (IR) cells was reduced (77.4% compared to control), but not fibers. The number of PB-IR neurons and fibers was also reduced on the experimental side (88.5% compared to control), In the other hand, the CR-IR cells were dramatically increased (642% compared to control), but CR-IR fibers were markedly decreased on the experimental side. The colocalization between CB-CR and PV-CR was rarely observed in the superior colliculus Conclusion: These results suggest that the changes of retinotectal projection may alter the expressional pattern of CBPs in different manners; relatively stable in CB- and PV-IR neurons and plastic in CR-IR neurons.

In this study, we have measured scintillating light generated in a fiber-optic dosimeter by high energy photon and electron beams using a charge-coupled device. The intensity of Cerenkov lights are also measured and characterized as functions of incident angles and energies of the high energy beams from a clinical linear accelerator. To minimize or remove Cerenkov light, a simple subtraction method using a background optical fiber and wavelength discrimination method using optical filters are investigated. Also, the intensities of Cerenkov light induced by high energy photon and electron beams are compared.
