Purpose: Pain in terminal cancer patients may be refractory to systemic analgesics or associated with adverse drug reactions to analgesics. Epidural analgesia has been effectively used in such patients for pain control. However, this method does not provide pain relief to all patients. The efficacy and complications of continuous epidural analgesia were evaluated for expanding efficacy in terminal cancer patients. Materials and Methods: The charts of patients who received epidural analgesia for over 5 years for the control of terminal cancer pain were reviewed retrospectively. Results: Ninety-six patients received 127 epidural catheters. The mean duration for epidural catheterization was 31.5±55.6 (5-509) days. The dose of epidural morphine increased by 3.5% per day. The efficacy of epidural analgesia at 2 weeks follow up revealed improved pain control (n=56), as the morphine equivalent drug dose dropped from 213.4 mg/day to 94.1 mg/day (p<0.05) at 2 weeks follow up. Accordingly, after 2 weeks institution of epidural analgesia, there was a significant reduction in the proportion of patients with severe pain, from 78.1% to 19.6% (p<0.05). Conclusion: Epidural analgesia was an effective pain control method in patients with terminal cancer pain, however, a systematized algorithm for the control of cancer-related pain in needed.

전연수,김대우,강유진,김용신,인장혁,길호영 대한정맥마취학회 2001 정맥마취 Vol.5 No.1

Background: It has been known that the awareness during anesthesia is quite a frequent problem, especially in pregnant woman. The causes of awareness are not definitive. The purpose of this study is to find out if there is any difference between pregnant and nonpregnant woman in depth of anesthesia using the bispectral index (BIS) and effect site concentration at induction, maintenance and recovery. Methods: We allocated 20 nonpregant women who would receive abdominal surgery for 1 hour as group 1 and 20 pregnant women scheduled for cesarean section under general anesthesia as group 2. Anesthesia was induced with propofol target concentration (C_T) 6 ㎍/㎖, 3 min mode using Diprifusor_TM and maintained with propofol (C_T) 4 ㎍/㎖-N_2O 3 L/min-O_2 2 L/min. In each group, we measured induction time, induction dosage, effect site concentration for BIS_50 during induction. And average BIS, ratio of below BIS_40 or above BIS_60 were checked throughtout the maintenance. Also we measured the BIS and the effect site concentration of propofol at the time of eye opening and recovery of orientation. Results: There was no significant difference in elapsed time, propofol dosage, effect site concentration for BIS_50 during induction, nor in average BIS, ratio of below BIS_40 or above BIS_60 during maintenance between groups. At the time of eye opening and recovery of orientation, there was significant higher effect site concentration in pregnant group (P < 0.05) while BIS showed no difference. Conclusions: According to the result, there was no significant difference on BIS throughout the the recovery of anesthesia the effect site concentration was higher in pregnant woman, which means higher requirement of anesthetic drugs in pregnant woman. In conclusion, we have to consider proper use of anesthetics for prevention of awareness during anesthesia.

Structural and Electrochemical Characterization of LiFePO4 Synthesized by Hydrothermal Method

전연수,김은미,진보,전대교,한젠지,구할본 한국전기전자재료학회 2007 Transactions on Electrical and Electronic Material Vol.8 No.1

Phospho-olivine LiFePO4 cathode materials were prepared by hydrothermal reaction. Carbon black was added to enhance the electrical conductivity of LiFePO4. The structural and morphological performance of LiFePO4 and LiFePO4-C powders were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM) and transmission electron microscope (TEM). LiFePO4/Li and LiFePO4-C/Li cells were characterized electrochemically by cyclic voltammogram (CV), charge/discharge experiments and ac impedance spectroscopy. The results showed that the discharge capacity of LiFePO4/Li cell was 147 mAh/g at the first cycle and 118 mAh/g after 30 cycles, respectively. The discharge capacity of LiFePO4-C/Li cell with 5 wt% carbon black was the largest among LiFePO4-C/Li cells, 133 mAh/g at the first cycle and 128 mAh/g after 30 cycles, respectively. It was demonstrated that cycling performance of LiFePO4-C/Li cell with 5 wt% carbon black was better than that of LiFePO4/Li cell.

Countless efforts have been made to improve the road safety audit system through accident and traffic pattern analysis for the post-opening phase of the road, enhancing domestic road safety conditions and decreasing the number of fatalities. The study aims to analyze road safety audit factors and traffic accidents for the post-opening phase of the road in order to derive significant conclusions. First, the study collected and classified road-related data from 25 self-governing districts, Gu, in Seoul, and proposed definition of each classification. Subsequently, an accident density regression model using road safety data was developed. The result of the multiple regression analysis proved that factors such as population density, number of cars per person, facility per sidewalk length, middle-scale road length had a higher impact on accident density than any other factors. However, the study had limitations in analyzing data separated by road types due to the difficulties concerning data collection. Nevertheless, the study will ostensibly be a good source of information for those who are interested in studying further for identifying influences in road safety. 국내 교통사고 사망자 수를 줄여 교통안전을 달성할 목적으로 도로교통 안전진단 제도는 운영단계의 교통사고·교통 패턴을 분석해 개선되었다. 이 연구는 도로안전진단항목 검토와 운영단계의 교통사고 분석을 실시해 시사점을 도출하고자 한다. 먼저 이 연구는 서울특별시 25개 자치구를 대상으로 도로 데이터를 도로안전진단항목에 따라 분류하였고 그 정의를 제시하였다. 그다음은 다중회귀분석과 선행연구 검토를 수행하여 교통사고밀도 영향요인 통계분석과 시사점을 도출하였다. 다중회귀분석을 수행한 결과, 인구밀도·1인당 자동차 등록대 수·보도연장 당 보도상 영업시설물·중로연장이 교통사고 밀도에 통계적으로 유의미한 양(+)의 영향을 주는 것으로 분석되었다. 분석결과에 따라 교통사고 밀도를 종속변수로 하는 최적의 다중회귀모델을 제시하였다. 이 연구는 자료 수집의 어려움으로 도로 위계별 분류에 따른 교통사고 밀도 분석, 도로의 특정 구간·교차로 등을 바탕으로 한 연구를 수행하지 못한 한계가 있다. 이 연구결과를 바탕으로 앞으로 도로 위계별 교통사고 영향분석연구, 실제 도로구간과 시설물에 관한 구체적인 연구 등을 수행할 수 있을 것이다.

A 70-year-old male was performed TURP (Transurethral resection of the prostate) under the diagnosis of benign prostate hyperplasia. Under general anesthesia, two times of TURP and suprapubic prostatectomy were performed for bleeding control during 8 hours. At the end of the operation, hypotension with bradycardia, severe ST elevation, QRS widening, T wave inversion and ventricular tachycardia on EKG appeared. Under the assumption of the diagnosis of hyponatremia, we treated with NaHCO3 and lasix, but cardiac arrest was followed by cardiopulmonary resuscitation. During postoperative five days, patient's cardiopulmonary status was supported by cardiotonic drugs and mechanical ventilation. We report this case to recall TURP syndrome and its management with the review of the relevant literatures.

Background: Postoperative pain degree is variable according to the site, type, and method of operation. This study compared the pain degree and amount of analgesics required among 3 types of operation. Methods: Ninety patients were selected that cesarean section (Group I, n = 30), open total hysterectomy (Group II, n = 30), laparoscopic total hysterectomy (Group III, n = 30) were scheduled. Patients received PCA with basal rate 2 ml/h, bolus 1 ml, lockout interval 5 min using fentanyl and ketorolac. We evaluated VAS at 30 min, 2, 6, 12, 18, 24, 36, 48 h postoperatively, demand of button and attempt of button, 6 hourly used amount of analgesics; side effects and degree of satisfaction after 24, 48 h postoperatively. Results: The rest VAS decreased below 30 at 6 hr in group I & II and at 2 hr in group III. More analgesics were needed for the first 6 hr compared with remained time in 3 groups (group I vs. group II vs. group III, P < 0.05). Total amount of analgesics including loading dose were fentanyl 1,536 ± 342μg, ketorolac 167 ± 34 mg for group I; 1,212 ± 215μg, 132 ± 30 mg for group II; 866 ± 125μg, 97 ± 27 mg for group III (group I vs. group II vs. group III, P < 0.05). Conclusions: The postoperative pain was painful as order of cesarean section, open total hysterectomy, and laparoscopic total hysterectomy. The pain was reduced 6 hr in laparotomy and 2 h in laparoscopy. (Korean J Anesthesiol 2007; 52: 166~71)
