Midazolam, a water soluble benzodiazepine, was compared with diazepam as a sedation for spinal anesthesia. Forthy healthy patients were allocated at random to receive midazolam 0.1mg/kg or diazepam 0.2mg/kg at 15 min after tetracaine inction for spinal anesthesia and increments of half of the initial dose every 2 min to induce sleep. Mean dose of midazolam 8.5 mg and diazepam 17.1 mg were injected for sedation throughout surgery. There was no difference concerning sedation level during surgery and speed of recovery. With the same degree of sedation, midazolam produced a higher frequency of anterograde amnesia(70% vs. 30%). Uenous tolerance was better for midazolam. Neither drug caused obstruction of airway nor significant cardiovascular change. Higher degree of amnesia and venous tolerance with midazolam may be advantages of sedation for spinal anesthesia.

Since Dongboo City Hospital cares patients with medicaid and poor socio-economic status in large percentage, we analized all the newborns delivered at the hospital from 1984 to 1992 by their birth weights, gender, gestational age and their Medical Care System. We found our babies?mean birth weight was lower than National standard mean birth weight of 1975 and 1985 (published by KPA) and also lower than other reported studies. But the fact than mean birth weight has been increasing since 1990 is encouraging.

BACKGROUND: Ropivacaine closely resembles bupivacaine with propyl group substitutes for butyl group at the same position. Ropivacaine is presented as 100% S-isomer with important implication of safety and less cardiotoxic than bupivacaine. Because of this, ropivacaine is used as an epidural anesthesia. However this study was performed to evaluate clinical effects of ropivacaine for spinal anesthesia. METHODS: Thirty patients (ASA I-II) scheduled for elective lower extremity operation were randomly selected and received spinal anesthesia with 3 ml of 0.75% isobaric ropivacaine. The patients were placed in the lateral position and dura puncture was performed at the L3-4 interspace using the median or paramedian approach with a 25 G Quincke spinal needle. After spinal anesthesia, sensory block was assessed using the pin-prick test every 2 min., motor block was assessed using a four-point scale, and circulatory variables were monitored every 5 min. RESULTS: The mean sensory block level was T 8.6 and the maximum sensory block level was T4. Time needed for extremity motor block was 10.8 min. and 25 of 30 patients reached Bromage scale 3. Duration of motor and sensory block were 260.6 min. and 422.3 min. Hemodynamic changes (arterial pressure and pulse) were stable during anesthesia and complications were rare. CONCLUSIONS: We concluded that 0.75% isobaric ropivacaine was suitable for spinal anesthesia with good lower extremity sensory and motor block, and it was long-lasting without any specific complications.

The occurrence of injuries and death caused by traffic accidents have been increasing during last few decades in Korea, which resulted in enormous personal, social and economic loss in terms of death, disability, labour days and medical costs incurred for treatment. Generally, it is well known and even became an hot sociopolitical issue that the duration of hospital stay for traffic accident patients are much longer than that of other patients with the similar condition. The objective of the study is to find out epidemiologic characreristics and management pattern of traffic accident patients in a general hospital of medium-sized, industrialized town. This study was carried out on 177 cases injured by motor vehicle accidents, who were admitted and treated in a general hospital from Feb. 1, 1997 to Sept. 30, 1997. The results obtained are as followings: The most of the patients(44%) were 20-30 years old age group although the occurrence of injuries was more frequent among older ages, 50's for male and 60's for female being 2.1 times more frequent among male. The traffic accidents occurred most frequently(14.1%) in the morning(06:00-08:00) and afternoon(14:00-16:00), and on Saturdays(20.3%); the (14.1% traffic accidents were frequent during weekends for passengers whereas it was more frequent during weekdays for pedestrian. Old and child pedestrians were most vulnerable subjects to traffic accidents. The most common site injured was head(19.9%) and the injury types were fracture of lower extremity(9.3%), skull fracture(8.6%) and rib fracture(8.6%) for both sexes; rib fractures/thoracic spine fractures(12.0%) for female and tibia/ fibula fractures(11.6%) for male. Mean days of hospital stay presumptively judged by the doctor who examined, made diagnosis and admitted the patient was 43.8 days compare to 38.4 days of actual mean days of hospitalixation. On the other hand, the optimal mean days of hospital stay for the patients determined by two doctors independently was estimated to be 26.6 days. Thus the difference between actual days of hospitalization and optimal days of hospitalization was 11.7 days, which can be regarded as excess hospitalization days. It consists 30.5% of actual hospitalization days, an enormous waste of resources. The only factor associated with this excess hospitalization was payment responsibility for the hospital cost; when the hospitalization expenses are to be paid by the person inflicted the injury there were always excess days of hospitalization regardless of insurance status.

The incidence of gastric cancer is high in old age group and low in young age group, extremely rare in child age. So the diagnosis of gastric cancer in young age is often delayed, and this, with other factors such as poorly differentiated histopathologic tendency and rapid growing nature, makes the prognosis poorer than in other age guoup. Therefore it should always be remembered that the young who has gastric symptom may have malignancy in his stomach in spite of the age. We report a case of early gastric cancer in a 16-years old male with the review of the literature.

Phylloides tumor is very similar to giant fibroadenoma in that they have benign appearance in breast radiologic image. Fibroadenoma has no malignant potential, but phylloides tumor is locally recurrent, invasive and may occasionally metastasize. It thus appears that evaluation of the differential point of the two tumor groups by radiologic study is very important. We retrospectively compared sonographic find;.ngs of 6 cases of phylloides tumor with those of 4 cases of fibroadenoma, which proved pathologically in Ye mgnam University Hospital from 1984 to 1986. The mean age of the patients were 31.8 years old(from 14 to 41 years old) in phylloides tumor and 28.8 years old (from 17 to 40 years old) in giant fibroadenoma, respectively. The viewpoints of this analysis were size, shape and contour of the masses, internal echo pattern, posterior enhancement, and especially the existence of peripheral cyst or septal band echo. We found that diffenentiation of these two tumors by sonography was difficult. But peripheral cyst was found only in phylloides tumor and septal band echo was found largely in giant fibroadenoma. Although the existence of peripheral cyst or septal band echo in the breast mass was not pathognomonic findings, we suggest that the existence of septal band echo is preferential finding to fibroadenoma, and peripheral cyst is preferential finding to phylloides tumor.

Pulmonary artery sling is a rare congenital condition in which the left pulmonary artery arises anomalously fmm the right pulmonary artery extrapericardially and encirdes the right main stem bronchus and passes between the trachea and esophaghus to reach the hilum of the left lung. Respiratory obstruction vesults from compression of the lower area of trachea and right main stem bronchus. It is rare cause of respiratory distress in the new bom and may be associated with significant morbidity and mortality. We experienced the case of pulmonary artery sling with diffuse trachea stenosis and congenital heart disease (pulmonary atresia and PDA) and confirmed the anomaly by bronchogram and MRI. The presumed cause of death was respiratory obsruction due to pulmonary artery sling.
