Although there are many peri-operative measures to reduce core temperature loss during operation, rapid drop has been experienced in the first sixty minutes following induction of general anesthesia. Recently, preoperative warming has been emphasized to prevent inadvertant hypothermia during operation. The purpose of this study is to find the effect of preoperative warming on reducing rectal temperature drop in surgical patients. With informed consent, 46 female adult patients, scheduled for total abdominal hysterectomy or salpingo-oophorectomy in the Seoul National University Hospital from September 3, 1996 to September 19, 1996 were divided into two groups. The variables of age and body surface were matched between the two groups as possible. Among them, 24 patients were preparatively covered up to the shoulders with a forced-air warming blanket(WARM TOUCHTM). set between 36-40degrees C for prewarming, and the other 22 patients(control group)were not before the induction of anesthesia. Rectal temperature was measured by mercury thermometer for rectum after admission to the operating room and by rectal probe which was inserted in the rectum just before the induction during the operation. The rectal temperature was monitored and recorded at every fifteen minutes for the first sixty minutes after the induction and each step during the surgery(intubation, surgical draping, peritoneum opening, one hour and the end of the operation) Collected data were analyzed by means of t-test, Repeated Measures Analysis of Variance with PC-SAS. The results of this study are as following. (1) There was no significant difference between the two groups in age, weight, height, room temperature, basal rectal temperature, operation time. (2) Temperature gradient of the rectal temperature in the warming group was less steeper than that in the control roup during the first sixty minutes after general anesthesia. (3) The rectal temperature measured at every fifteen minutes for the first sixty minutes and the end of surgery after the general anesthesia showed the difference between the two groups during surgery. (4) There was no rectal temperature difference during the intubation, however there was significant temperature difference between the two groups from draping to the end of surgery. In conclusion, prewarming of the surgical patient before induction resulted in increased the skin temperature and heat content, which relieved the dangerous core temperature drop which is potential to be provoked within one hour after induction of the surgical patients and kept the rectal temperature higher than that of the control group during surgery. The suggestions from this study shown below : First, further study is needed to find the preventive effect of the core temperature drop in the first sixth minutes after anesthetic induction by preoperative warming for gastrorectal, thoracic surgery patients who man have the core temperature drop during the operation. Second, in other to keep patient normothermia during the surgery, it needs to study whether using pre-and peri-operative warming can prevent hypothermia or not. Finally, the study of the peroperative warming effect on surgical patients' relaxation and thermal discomfort before the operation is needed because most patients in the case group said to have felt thermal comfort ; 'comfortable' and 'good'.

Balloon-tipped, flow-directed (Swan-Ganz) catheters are used commonly for monitoring of cardiac function in patients undergoing cardiac surgical procedures. We report a case of pulmonary hypertension with hypoxemia which may be caused by incorrect positioning of pulmonary artery catheter (PAC) during CABG. Pulmonary arterial pressure (PAP) of 70/40 mmHg which was nearly high as systemic pressure was measured when we tried to wean patient from cardiopulmonary bypass. But, TEE (transesophageal echocardiography) showed nonspecific finding. PAP decreased soon and maintained about 33/16 mmHg for a few minutes. But, the PAP elevated high to 70/40 mmHg again and the arteral oxygen tension (PaO2) decreased to 61.2 mmHg. When we withdrew the PAC to the depth of 35 cm, the PAP and systolic pressure returned to normal range and PaO2 elevaed to 320 mmHg. End tidal CO2 was elevated from 30 mmHg to 35 mmHg.

BACKGROUND: Presently, it is well known that there are neurological and systemic complications after carbon monox-ide (CO) intoxication. Until recently, delayed-onset movement disorders after CO intoxication were rarely reported. We analyzed 32 patients with delayed onset movement disorders after CO intoxication. METHODS: We reviewed the medical records of 242 patients admitted to the Yonsei University Medical Center from January 1986 to December 1996 due to CO intoxication. Patients were analyzed with respect to movement disorders, onset, latency, and radiological findings. RESULTS: Among the 242 patients of CO intoxication, 32 (13.2%) patients had delayed-onset movement disorders. Of these, 23 (71.9%) had parkinsonism, 5 (15.6%) had dystonia, 3 (9.4%) had chorea, and 1 (3.1%) had myoclonus. The mean age of the patients was 46.66 +/-16.91 years. Among the 4 patients with CO intoxication occuring at age 17 or younger (Childhood group), 2 had parkinsonism and 2 had focal dystonia. The mean age of the Childhood group was 1 7 . 7 5 +/-6.99 years. Among the 28 patients with CO intoxication occuring at age 18 or older (Adult group), 21 (75%) had parkinsonism, 3(10.7%) dystonia, 3(10.7%) chorea, and 1(3.6%) myoclonus. Among the 3 patients with dystonia in the Adult group, 1 had focal dystonia and 2 had segmental dystonia. The mean age of the adult group was 50.79 +/-1 3 . 4 6 years. The mean latency between CO intoxication and the onset of movement disorders was 27.20 +/-27.94 weeks in the Childhood group and 9.60 +/-14.97 weeks in the Adult group. The mean latency between CO intoxication and the onset of movement disorders was 6.44 +/-6.76 weeks in parkinsonism, 41.76 +/-27.99 weeks in dystonia, 4.0 weeks in chorea, and 8.0 weeks in myoclonus. The mean latency in dystonia was longer than in the others. Among the 23 patients who underwent brain computed tomography, 12 (52.2%) had abnormal findings. Low density lesions were found in the globus pallidus (13.0%), cerebral white matter (13.0%), and both globus pallidus and cerebral white matter (17.4%). One (14.3%) patient showed cortical atrophy while another patient showed both cortical atrophy and low density in cerebral white matter. CONCLUSIONS: The development of a delayed-onset movement disorder after CO intoxication is not rare. In our research, the radiological findings of patients with delayed-onset movement disorders after CO intoxication were inconsistant. The findings revealed no correlations with the various types of delayed-onset movement disorders.

Nimodipine, a potent, central active, calcium channel blocker, is known to relieve vasospasm, increase cerebral blood flow(CBF) and affect positively on clinical outcome in patients with subarachnoid hemorrhage. Experimentally, the potent effects on both vascular dilatation and increasing CBF were proven. However, there are still controversies and many debates at present about the actual clinical effects of nimodipine on subarachnoid hemorrhage. To evaluate the clinical effectiveness of nimodipine on aneurysmal subarachnoid hemorrhage in our series, we analyzed 122 consecutive patients with ruptured aneurysms who underwent operations between October, 1993 and June, 1995. These patients were grouped as follow: Group I consisted of 63 cases(52%) in which the patients were treated with nimodipine and Group II consisted of 59 cases(48%) in which the patients were treated conventionally. Administration of nimodipine was started immediately after the radiological diagnosis of ruptured aneurysm. The dose of nimodipine was 0.5microg/kg/min via continuous intravenous infusion for 7 to 10 days after the subarachnoid hemorrhage. After a course of intravenous treatment, oral administration of nimodipine was then continued for up to 21 days after subarachnoid hemorrhage in a dose of 60mg every four hours. We analyzed two groups based on patient's age, sex, aneurysmal location and size, timing of surgery, presence of hypertension, Hunt-Hess grade, presence of vasospasm on preoperative angiography and Fisher's CT classification. We also analyzed the incidence of delayed ischemic deficits(DID) and outcome(GOS) in each group. There were no significant differences in any of these parameters between nimodipine-treated group and the control group(p>0.05) and also, no significant differences in the distribution of DID or outcome between two groups (p>0.05). Based on these results, we conclude that nimodipine does not provide any significant beneficial effects on the prevention of DID and outcome in the patients with aneurysmal subarachnoid hemorrhage.

BACKGROUND: This study was performed to evaluate our experience on laparoscopic appendectomy. METHODS: Retrospective analysis was performed on 2,856 patients who had been operated by laparoscopic appendectomy under diagnosis of acute appendicitis at the Sung-Ae Hospital and Kwang-Myoung Sung-Ae Hospital from October 1991 to July 1998. RESULTS: Among 2,856 patients who had undergone laparoscopic appendectomy,2,379 patients (83.3%) were operated due to simple acute appendicitis, 275 patients (9.6%) due to perforated appendicitis. Operation time was 44.6 minutes for simple acute appendicitis and 60.3 minutes for perforated appendicitis. In perforated appendicitis, intra-peritoneal irrigation and drain insertion was performed. The length of hospital stay in patient with simple acute appendicitis was 3.7 days (5.82 days in conventional appendectomy) and patients with perfotrated appendicitis was 6.1 days (9.91 days in conventional appen-dectomy). Complications such as wound infection, intra-abdomen abscess, trocar site bleeding, subcutaneous emphysema developed in 43 (1.5%) patients (79/1,947, 4.5% in conventional appendectomy). In 202 (7.1%) patients, appendix was normal, but another diseases were detected, including acute pelvic inflammation, ovarian cyst, mesenteric lymphadenitis, enteritis, diverticulitis in order. CONCLUSION: Overall complication rate was lower in laparoscopic appendectomy compared with conventional appendectomy and the length of hospitalization of laparoscopic appendectomy was shorter. When the acute appendicitis is suspected, especially in the reproductive women, the laparoscopic approach would be better diagnostic and therapeutic value than conventional method. Therefore laparoscopic appendectomy would be replaced with conventional appendectomy.

Epidural nerve block is the most widely practiced procedure in the pain clinic. Accidental dural puncture during epidural nerve block also has been associated with postdural puncture headache and total spinal anesthesia. Especially, total spinal anesthesia is the most serious complication of epidural nerve block and can lead to a life threatening conditions. We have experienced two cases in whom total spinal anesthesia occurred during epidural nerve block for neck and lower back pain control. Immediately after epidural nerve block, the patients became unresponsive and apneic with loss of muscle tone in all extremity. We performed resuscitations and about 3 hours later the patients recovered completely without any complication.

Membranous lipodystrophy is a peculiar type of fat necrosis, present in patients with various types of skin diseases. It is charaeterized by the presence of microcysts and macrocysts lined by amorphous eosinophilic material with a crenelated arabesque appearance and microgranules in the subcutis with massive fat necrosis. The eosinophilic lining and microgranules stain positively with periodic acid-Schiff, are resistant to diastase, and also stain with Sudan black B. We report three cases of subcutanous membranous lipodystrophy in patients with erythema induratum, posttraumatic panniculitis and morphea with typical clinical and histopathologic findings.

OBJECTIVE: Vasospasm of cerebral vessels remains a major source of morbidity and mortality after an aneurysmal subarachnoid hemorrhage (SAH). The purpose of this study was to evaluate the safety and efficacy of transluminal balloon angioplasty (TBA) for SAH-induced vasospasm. METHODS: Eleven patients with an angiographically confirmed significant vasospasm (>50% vessel narrowing and clinical deterioration) were studied. A total of 54 vessel segments with significant vasospasm were treated by TBA. Digital subtraction angiography was used to confirm the presence of vasospasm, and TBA was performed to dilate vasospastic arteries. Medical and angiographic reports were reviewed to determine technical efficacy and for procedural complications. RESULTS: TBA using Hyper-Glide or Hyper-Form balloons (MicroTherapeutics, Irvine, CA) was successfully accomplished in 88.9% vasospastic segments (48 of 54), namely, in the distal internal carotid artery (100%, n=7), the middle cerebral artery (100%), including the M1 (n=10), M2 (n=10), and M3 segments (n=4), in the vertebral artery (100%, n=2), basilar artery (100%, n=1), and in the anterior cerebral artery (ACA), including the A1 (66%), A2 (66%), and A3 segments (100%). Vessel diameters significantly increased after TBA. There were no cases of vessel rupture or thromboembolic complications. GCS at one day after TBA showed an improvement in all patients except one. CONCLUSION: This study suggests that TBA using Hyper-Glide or Hyper-Form balloons is a safe and effective treatment for subarachnoid hemorrhage-induced cerebral vasospasm.

PURPOSE: Streptococcus pyogenes is an important cause of invasive diseases in children. We aimed to describe the clinical characteristics of invasive infections due to S. pyogenes in children in Korea. METHODS: A retrospective study of children under 18 years of age with invasive infections due to S. pyogenes at Seoul National University Children's Hospital between March 1992 and December 2012, and Seoul National University Bundang Hospital between March 2003 and December 2012 was conducted. Demographic factors, clinical characteristics, laboratory findings, treatment, mortality and morbidity of all patients were reviewed. RESULTS: A total of 30 among 36 cases identified as invasive disease due to S. pyogenes were available for review. There was a predominance for male subjects (male:female=2.75:1). The median age was 50 months (range 12 days to 15 years) and 53.3% were under 5 years of age. Skin and soft tissue infections (9/30, 30.0%), bacteremia without identified focus (4/30, 13.3%) and bone and joint infections (6/30, 20.0%) were the most frequent clinical presentations. Streptococcal toxic shock syndrome (3/30, 10.0%) pulmonary, abdomen and central nervous system infections (2/30, 6.7%) were also seen. There was a peak in number of patients in year 2012 (9/30, 30.0%). There were no cases of mortality. Erythromycin and clindamycin resistance rates were low by 3.8% and 7.5%, respectively. CONCLUSION: We studied the clinical presentations of invasive infections due to S. pyogenes during the past 20 years in Korean children. The findings of this study help us understand the characteristics of the disease, enhancing early recognition and prompting adequate antibiotic therapy which is important in reducing morbidity and mortality.
