Background: Some studies reported that lowering central venous pressure (LCVP) during liver resection could significantly reduce the intra-operative blood loss, however it is still controversial concerning LCVP induced renal dysfunction, hypovolemia, hemodynamic instability. This study evaluated the association of low central venous pressure with blood loss during liver resection comparing the control group. Methods: A total 62 patients aged 20 to 70 underwent hepatectomy by the same group of surgeon were randomized into group L (CVP<10 mmHg, n = 30) and control group C (CVP>10 mmHg, n = 32) during dissection and lobectomy period. Data such as age, sex, concurrent disease, liver resection site (right or left), pre-, intra- and postoperative day 3 hemoglobin, blood urea nitrogen, creatinine, bleeding time, prothrombin time, activated partitial thromboplastin time, intraoperative blood loss, urine output, transfusion volume, length of hospital stay were collected and compared between the two groups and t-test was used for comparison of results. Results: The difference of total blood loss between two groups was 193.6 ± 432.2 ml (group L; 589.1 ± 380.8 ml, group C; 782.7 ± 316.7 ml), however statistically insignificant (P value = 0.1243). Additionally, there were no significant differences in other data including the length of hospital stay. Conclusions: Our results suggest maintaining CVP under 10 mmHg is not effective in reducing blood loss during liver resection. (Korean J Anesthesiol 2007; 52: 663~8)

임상연구 : 갑상선절제술과 유방절제술에서 Propofol과 Remifentanil을 이용한 전정맥마취 시 마취 유지 및 각성의 비교

Background: This study investigated the effect of type of surgery on consumption of propofol and remifentanil and recovery index. Methods: Fifty female patients (ASA physical status 1, 2) scheduled for thyroidectomy (Group I) or mastectomy (Group II) received total intravenous anesthesia (TIVA) with propofol and remifentanil. The anesthesia was maintained with target-controlled infusion (TCI) of propofol and remifentanil under bispectral index (BIS) monitoring. The effect site concentration of propofol was controlled for maintaining BIS values within the range of 45-50. The effect site concentration of remifentanil was controlled for maintaining blood pressure and heart rate within 20% of baseline values. Blood pressure, heart rate, BIS, effect site concentration of propofol and remifentanil were measured before induction, during induction, at the beginning of operation, at the end of operation, and during recovery. The time from discontinuation of propofol to eye opening and regaining of orientation, total amount of propofol and remifentanil used, and the amount of drug per body weight kilogram per hour were investigated. Results: There were no significant differences between Group I and II on the amount of remifentanil used. Although the amount of propofol consumed per body weight kilogram per hour was larger in Group II, there were no significant differences of recovery index between Group I and II. Conclusions: There were no significant differences in the amount of propofol and remifentanil consumed and recovery index in thyroidectomy and mastectomy under TIVA. The larger amount of propofol consumed per body weight per hour in Group II was thought as a result of shorter operation time than Group I. (Korean J Anesthesiol 2007; 53: 169~73)

Objectives: To investigate the relationship of internet addiction and depression, and evaluate other possible related factors. Methods: Data was based on the questionnaires from 300 college students in Seoul. Gender, age, major, family income, academic performance, people they live with, location, and main use of internet were included. We used Young's Internet Addiction Test and Beck Depression Inventory(BDI) to measure the depression and addiction degree. Results: In logistic regression analysis, it was found that gender, depression degree and main use of internet were significant variables. There were 136 males, 144 females in this study, and the risk of being addicted to internet were 10.9 times(CI:2.67~44.68) higher in male than female. People with moderate depression (Beck's Depression Inventory(BDI) Score>20) also had higher risk(11.4 times, CI:2.03~63.95) to be addicted in internet than normal group. Lastly, in case of internet use, people who use internet for games and chatting were 6.38(CI:1.38~29.63) and 4.84 times(CI:1.30~18.06) risky compare to the group with web surfing. Conclusion: The result of this study suggests that there is noticeable relationship of internet addiction and depression. However we do oat have evidence of exact relation between them, therefore more studies should be done.

증례보고 : 에피네프린 국소 침윤 후 발생한 급성 고혈압 시베타 차단제 투여 후에 발생한 급성 심부전
이지연 ( Ji Yeon Lee ),김종훈 ( Chong Hoon Kim ),이성진 ( Sung Jin Lee ),전나형 ( Na Hyung Jun ),박윤곤 ( Wyun Kon Park ) 대한마취과학회 2007 Korean Journal of Anesthesiology Vol.52 No.5
Topical epinephrine can cause severe hypertension, ventricular tachycardia, myocardial ischemia, cardiac arrest or pulmonary edema. The increased blood pressure and left ventricular afterload, as well as decreased left ventricular compliance caused by epinephrine may also decrease the cardiac output. If a beta blocker is used in these situations, the resulting decreased contractility and inability to increase the heart rate may further compromise the cardiopulmonary function. A 26 year-old man developed tachycardia and hypertension following the local infiltration of epinephrine 2 ml (1:10,000) around the nasal mucosa and an intramucosal injection of epinephrine 7.2 ml (1:100,000). He was treated with intravenous esmolol 10 mg. He showed a decreasing heart rate and blood pressure, depressed ST segments and inverted T waves. At the same time, the pulsation of the femoral arteries was not palpable. Cardiac massage was started. He was treated with intravenous atropine 0.5 mg and epinephrine 5μg. He recovered from circulatory failure after this treatment and his ECG showed a normal sinus rhythm. (Korean J Anesthesiol 2007; 52: 591~5)
