BACKGROUND: It has been a standard practice in many institutions to combine light general anesthesia with epidural block for abdominal and pelvic surgery. We attempted to prove the effectiveness of prehydration and to find an suitable epidural local anesthetic dose in terms of hemodynamic stability for upper abdominal surgery. METHODS: For preliminary studies, 11 patients scheduled for elective upper abdominal surgery had received general anesthesia immediately after epidural anesthesia. After epidural injection of 10~16 mL of 2% plain lidocaine into the T9~10 intervertebral space, the changes in blood pressure were observed. Thirty-two patients scheduled for elective upper abdominal surgery were divided into two groups. In group A (study group), after prehydration with Hartmann solution (10 mL/kg), 5~7 mL of 2% plain lidocaine was injected into T8~9 or T9~10 intervertebral space and general anesthesia was then induced. Group B (control group) received general anesthesia only. RESULTS: There were no significant differences in hemodynamics between the epidural with general anesthesia and the control group except SVR (systemic vascular resistance). SVR in group A increased in contrast to the group B in which it remained unchanged. CONCLUSIONS: The combined epidural and general anesthesia, using prehydration and 0.5~1 mL/segment of 2% plain lidocaine at the T8~9 or T9~10 intervertebral space was safe without significant hemodynamic changes.

Acute multifocal hemorrhagic retinal vasculitis is a disorder of abrupt onset, of unilateral or bilateral visual loss associated with mild anterior uveitis multifocal retinal vasculitis, retinal hemorrhage, retinal capiHary nonperfusion,papillitis, vitritis. After the onset of the disease, recurrent episode of intraocular inflammation, vasculitis, and visual loss ate commonly seen associated with the late complications of secondary vitreous hemorrhage, neovascular glaucoma, and epiretinal membrane formation. In 1988, Blumenkranz and associates were the first to report 7 cases of this disease in America. The mode of presentation, associated symptoms, and fundus findings are suggestive of herpes class virus infection, although the etiology remains unknown. We experienced a case of acute multifocal hemorrhagic retinal vasculitis associated with multifocal retinal vasculitis, retinal hemorrhage and neovascu lar complications.

Although rare, agranulocytosis is the most serious, potentially fatal side effect of antithyroid drug. We experienced a 13-year-old girl who developed methimazole-induced agranulocytosis at 1 month after the initiation of treatment. Her granulocyte count recovered after discontinuation of methimazole and treatment with broad spectrum-antibiotics, G-CSF, and methylprednisolone. After recovery from agranulocytosis she was treated with radioiodine ablation therapy. Early detection and proper management of antithyroid drug-induced agranulocytosis is very important.

A 29 years old man was scheduled for carinal resection & tracheobronehial reconstruction under the diagnosis of malignant tumor in the carina. 1 ml of morphine-scopolamine was given intramusculary for premedication. After induction with pentothal-Na and succinylcholine, anesthesia was maintained with halothane, N2O, and flaxedil (Gallamine). Radial artery cannula was inserted for blood gas analyze sampling, and EKG was monitored continuously. Tumor mass was infiltrated from carina to right upper lobe opening and right lower lobe had severe bronchiectatic change. Right pneumonectomy, resection of carina and end to end anastomosis of trachea and left bronchus were performed without any trouble. During this procedure, anesthesia had been continued with left bronchial tube which was intubated through operating field. Left bronchial ventilation had increased resistance, elevated PCO2, and lowered pH & PO2. Partial ohstruction of left upper bronchial opening was suspected during this left bronchial ventilation due to deep bronchial intubation.

The purpose of the present study is to measure the viscosity of liquid in the capillary tube viscometer using the unsteady flow concept. The capillary tube viscometer is consisted of a small cylindrical reservoir, capillary tubes, and the mass flow rate measuring system interfaced with computer. Two capillary tubes with 1.152 and 3.002 mm (inner diameter) are used to determine the diameter effects on the viscosity measurements. The instantaneous shear rate and gravitational driving force in the capillary tube are determined by measuring the mass flow rate through the capillary tube instantaneously. The measured viscosities of water and aqueous Separan solution as the blood analogue fluid are in good agreement with the reported experimental data.

For the evaluation of exercise induced R wave amplitude changes in lead V5 (big up tri, openR) and multiple leads(summation operatorR), we studied 20 normal subjects and 21 ischemic heart disease patients with positive exercise test. All underwent submaximal, multiple leads multistage treadmill exercise testing. 14 to 20 normal subjects(70%) there were decreased R wave amplitude in multiple leads on treadmill exercise testing. 16 of 21 patients(76%) there were increased R wave amplitude on treadmill exercise testing. In normal group, R wave amplitude between rest and exercise was significantly decreased in lead V5 and multiple leads. In patients grous, R wave amplitude between rest and exercise was significantly increased in lead V5 and multiple leads. It is suggested exercise induced R wave amplitude changes probably enhance the diagnostic reliability by ST segment changes on treadmill exercise testing.

BACKGROUND: Laryngeal mask airway (LMA) is a useful instrument for routine anesthesia. It permits spontaneous or positive pressure ventilation but its use in obstetric anesthesia has not been described. In this study, we evaluated the effectiveness and the side effects of the LMA during elective cesarean sections. METHODS: Institutional approval and patients' permission were obtained. One thousand sixty-seven patients scheduled for elective an cesarean section, that have been NPO for more than 6 (6-48) hours were evaluated. They were premedicated with an H2 receptor blocker (ranitidine 50 mg i.m.) 1 hour before the operation. They were anesthetized with penthotal sodium (3-4 mg/kg), vecuronium (1 mg/10 kg i.m.) and then a 3 or 4 LMA was inserted after the mask ventilation with 100% oxygen for 1 min. The cuff was inflated with air 15.3 +/- 2.6 ml. On auscultation, air entry was good in both lungs. Anesthesia was maintained by 50% oxygen in N2O with 0.7 - 1.0% enflurane. Analgesics (tramadol 30 mg i.v.) was given incrementally after delivery of the baby. Manual assisted ventilation was used throughout the procedure. The number of insertion attempts, cuff volume and the incidences of complications were evaluated. RESULTS: In 1051 patients, the LMA was inserted on the first attempt. In 16 patients more than 2 attempts were needed and change to endotracheal intubation were needed in 7 cases. The mean cuff volume was 15 +/- 2.6 ml at insertion and increased to 18.5 +/- 3.2 ml after removal. The average airway pressure was 20 cmH2O during positive pressure ventilation, above that pressure air leakage was detected in 16 cases. Complications noted were mild sore throat in 5 cases, and blood tinged after removal of LMA in 3 cases but gastric distention was not detected. No incidence of aspiration was noted. CONCLUSIONS: In this study, the LMA proved to be a useful tool for the management of patients presenting for elective an cesarian section. There is the remote possibility of aspiration which did not happen in our study.

BACKGROUND: Analysis of the species and antimicrobial susceptibility trend of bacterial and fungal isolate from blood can provide the clinicians with important informations for the treatment of the patients. METHODS: We analyzed the species and antimicrobial susceptibility trends of microorganisms isolated from blood cultures from 1986 to 1996 at Kyunghee Medical Center. Identification of organism was based on conventional methods or commercial kit systems. Antimicrobial susceptibility test was done by the NCCLS disk diffusion method. RESULTS: The positive blood culture was obtained from 3,559 patients. Among the patients 95.6% showed aerobic and facultative anaerobic bacteria, 0.9% anaerobes, and 3.6% fungi. Escherichia coli was isolated most frequently, followed by Coagulase-negative staphylococcus, Staphylococcus aureus, Pseudomonas aeruginosa, Klebsiella pneumoniae, Enterococcus, alpha- hemolytic Streptococcus and Serratia. The proportion of patients with E. coli decreased from 34.5% in 1986 to 22.1% in 1996, while that of S. aureus increased from 9.7% to 13.9%. Proportion of methicillin-resistant S. aureus and the third generation cephalosporin-resistant K. pneumoniae increased during the study period. CONCLUSIONS: We conclude that E. coli is the most common cause of bacteremia at Kyunghee Medical Center. The third generation cephalosporin-resistant K. pneumoniae and methicillin- resistant S. aureus are increasing in proportion.
