Objectives : We evaluated the efficacy of ramosetron and ondansetron for preventing postoperative nausea and vomiting (PONV) in laparoscopic colectomy. Methods and Materials : Eighty patients who received laparoscopic colectomy were randomly divided into two groups: R group (ramosetron 0.1mg PO) and O group (ondansetron 4mg twice IV). Injection or oral medication was administered before the induction of anesthesia in each group. Injection was administered at the end of surgery in O group. General anesthesia was induced using propofol and rocuronium, and maintained with sevoflurane, remifentanil and air (FiO2 0.5), We investigated the incidences of PONV in each group by the Rhodes index of nausea, vomiting and retching (RINVR) at postoperative 6 and 24 hours. Results : The incidence of PONV was not different between group at each time points after surgery (at postoperative 6 hours: 20% in group R, 17.5% in group 0, at postoperative 24 hours; 12.5% in group R, 7.5% in group 0). There was no difference in the severity of PONV, satisfaction, rescue drug usage. Conclusion : Prophylactic therapy with ramosetron is as effective as conventional prophylactic therapy with ondansetron for preventing PONV in general anesthesia for laparoscopic colectomy.

It has been well known that respiratory status has affected the intracranial pressure by' changing the brain blood flow, and also ethanol has affected the respiratory system by inhibiting the respiratory center and has affected cardiovascular system by inhibiting the cardiac performance and decreasing the total peripheral resistance. However, effect of ethanol on intracranial pressure has not been studied satisfactorily. Thus, following experiment was performed to examine the change of the intracranial pressure after ethanol administration in the cats. Ethanol was infused intravenously by lg ethanol per kg body weight for 15 minutes. Intracranial pressure was measured through balloon inserted between epidura and skull. Arterial blood pH, Po_2, Pco_2, ethanol concentration were measured. The results obtained are surnmerized as follows. Blood ethanol concentration increased by linear and peaked at 15 minutes(blood ethanol concentration was 409±31 mg%). Po_2, Pco_2. and pH at 15 minutes were 80. 3±5. lmmHg, 49.2±3.3mmHg and 7.24 =0.015 respectively. Blood pressure began to decrease and arterial pulse pressure began to increase at 10 minutes and more and more at 15 minutes respectively. Intracranial pressure began to increase at 10 minutes (blood ethanol concentration was 316±33 mg%) and peaked as 168.7±11.4% contrast to control at 15 minutes and also amplitude of intracranial pulse wave was increased. From the above results, it was suggested that intracranial presssure and amplitude of intracranial pulse wave were increased significantly by inhibiting respiratory center and thereby dilatating cerebral blood vessels with intravenous ethanol administration.

PWM 인버터에 의해 구동되는 유도전동기에 발생되는 고주파 커먼 모드 전압은 전도성 EMI, 전동기 접지전류, 베어링 전류 및 다른 원치 않는 결과의 주원인이 된다. 인버터 제어의 무효벡터 스위칭 상태는 나머지 유효벡터 스위칭 상태에 비교하여 큰 커먼 모드 전압을 일으킨다. 그러므로 이 논문은 커먼 모드 전압을 완화하는 스위칭기법을 다룬다. 즉 정현파 PWM기법을 기본으로 한 커먼 모드 전압 제거방법을 제안하였다. PWM 신호는 각각의 정현파 기준신호와 120˚위상차가 나는 3개의 캐리어 파형과 비교하여 발생된다. 시뮬레이션과 실험적결과는 제안된 PWM 기법에서 커먼 모드 전압이 종래의 PWM 기법보다 약 66% 더 저감됨을 보였다. High frequency common mode voltage produced by PWM inverter fed induction motor is a major cause of conducted EMI. creation motor ground currents, bearing currents and other hamful products. The zero switching states of inverter control invoke large in comparison with the non-zero switching state of inverter control. We proposed a common mode voltage reduction method based on sinusoidal PWM technique. PWM signal are generated by comparing respective sinusoidal reference signal with three triangular carrier wave displaced of 120˚. Simulation and experimental result show that common mode voltages in the propsed PWM technique are reduced by approximate 66% more than conventional PWM technique.

A 57-year-old woman who was suffered from chronic back pain and radiating pain to left leg visited the local pain clinic. An accidental dural puncture happened at the L4-5 intervertebral space during the procedure with the loss of resistance technique using air. The epidural needle was removed, and a new insertion was done at the L3-4 intervertebral space with administration of the 0.5% lidocaine 8 ml mixed triamcinolone 40 mg. On the next day, she visited again the local pain clinic with complaining of headache. During an epidural autologuous blood patch procedure, she complained of a severe headache, nausea, vomiting, and developed generalized tremor of abrupt onset. There was no evidence of a dural puncture during the procedure. She was referred to our hospital at once. A brain CT scan showed air-filled cavities in basal cistern. She was given conservative treatment during 14 days. After 10 days, follow up brain CT scan showed no air-filled cavity in basal cistern. She was discharged from our hospital without complications.

Objective : There are controversies in pnmmg technique of rocuronium whether it can or can't shorten the onset time. We want to compare the effects of two different priming doses and intervals of rocuronium. Materials and Methods : After giving propofol, 50 patients were randomly assigned to 5 groups. Group I received a placebo, followed 3 min later by rocuronium 0.6 mg/kg. Priming doses and intervals of Group II, Ill, N, V were 0.06 rng/kg and 2 min, 0.12 mg/kg and 2 min, 0.06 rug/kg and 3 min, 0.12 mg/kg and 3 min, respectively. Total dose of rocuronium was 0.6mg/kg. Train of four (TOF) count or ratio and 1st twitch height of TOF (T1) were monitored with 15 secondsintervals. TOF ratio of each groups just before bolus injection, duration for TOF count to reach zero and duration for Tl to reach 95% depression after bolus injection were compared. Results : Duration for TOF count to reach zero and duration for Tl to reach 95% depression after bolus injection were decreased in priming groups compared to Group 1 (P < 0.01) In group V, significant depression of TOF ratio just before bolus injection was seen (P < 0.05). Conclusion : Priming technique with rocuronium is effective method to shorten the onset of neuromuscular block. But priming dose of rocuronium itself could cause hypoxia and aspiration in awake patients and should be used carefully. Priming dose of rocuronium 0.06 mg/kg and 2 minutes interval maybe relatively safe method.

To develop the functional pear fruitlet product, we prepared dried pear fruitlet and fermented pear fruitlet, respectively. Then we investigated their general characteristics, and viable cell number changes during the storage at room temperature. We also determined preference for their tastes. Dried pear fruitlet contained more ash and crude proteins as well as minerals than fermented pear fruitlet. However fermented pear fruitlet contained higher amount of edible fiber than dried pear fruitlet. Fungi were not detected from dried pear fruitlet during the storage experiment at room temperature. Numbers of bacteria from dried pear fruitlet were increased from 1.1☓105/g at the beginning to2.6☓106/g at the last day of experiment. When we determined change of fungi number during the storage of fermented pear fruitlet, we cannot detect fungi at the beginning but we detected 4.4☓102/g of fungi at the last day of storage experiment. Bacteria from fermented pear fruitlet were detected at around 1.0☓109/g during the storage periods. Preference for fermented pear fruitlet was superior to dried one.

저자들은 56세 여성 환자의 왼쪽 쇄골 하 정맥에 시행한 이식형 약제주입기 카테터의 삽입 후 발생한 비정상 위치에 대한 증례를 보고하고자 한다. 카테터의 끝은 환자의 늘 어진 가슴, 체위, 신체의 움직임, 카테터의 유동성 등의 영향으로 천자된 정맥 내에서 견인되고 뒤쪽으로 이동하였다. 환자는 어떠한 증상도 호소하지 않았지만 비정상 위치의 카테터는 심각한 합병증을 유발할 수 있기 때문에 제거되었다. 따라서 시술자는 약제주입기 삽입 전에 환자의 신체 상태와 단순 흉부 촬영상을 확인하고 카테터의 비정상 위치가 발생할 수 있는 위험 징후를 알아차려야 하겠다.
