        성상 신경절 차단이 기관내 삽관에 따른 심혈관계 반응에 미치는 영향

        라은길(Eun Gil Rah),윤정수(Jung Su Yoon),오현주(Hy 대한통증학회 1994 The Korean Journal of Pain Vol.7 No.2

        N/A The impact of cardiovascular changes occurred by endotracheal intubation is risky for pa- tients with ischemic heart disease, or intracranial pathologic conditions typically impairing ce- rebral autoregulatory mechanisms. Therefore, multiple approaches have been utilized to limit the impact of intubation and re- duce damage of central nervous and cardiovascular systems. These approaches include modifi- cations in intubation technique to diminish circulatory stimuli and pharmacologic modifica- tions of either the sensory afferent path or the circulatory response itself. We tried the stellate ganglion block, a kind of sympathetic block, for the same purpose and evaluated the results. The results of study are as follows, 1) Blood pressure and heart rate increased significantly after intubation as compared with preintubation in both control group and SGB group. 2) The difference of the two groups is not found. We conclude the above method does not control cardiovascular consequences of endotracheal intubation.

        미추마취시 Lidocaine 과 혼합한 약제가 진통의 발현 및 지속시간에 미치는 영향

        라은길,양홍석 대한마취과학회 1997 Korean Journal of Anesthesiology Vol.32 No.1

        Background : caudal anesthesia is a safe and reliable technique for surgical anesthesia as well as an alternative to narcotics for postoperative analgesia for procedure below umbilicus. Onset time and duration of local anesthetics had been influenced by local anesthetics with combined drugs. We wanted that the time required for the onset of local anesthesia should be short and long enough to allow time for the contemplated surgery. Method : To investigated the effect of lidocaine with combined drugs, 120 ASA physical status I, II patients who underwent perianal surgery with caudal anethesia. The patients were diveded into 5 groups : control group received 1.5% lidocaine 27ml, group I received lidocaine with epinephrine (1:200,000), group II received lidocaine with morphine 2mg, group III received lidocaine with fentanyl 50 g, group IV received lidocaine with clonidine 75 g. We have compared the onset time and duration of analgesia of 5 groups. Results : 1. The onset time of analgesia for pin prick test were not significantly changes between groups. 2. The duration of analgesia was significantly more prolonged in group II(863.8 222.1 min) than other three group I, III, IV. 3. The most common side effect was urinary retention(20 cases, 16.7%) in all groups(n=120). 6 cases(24%) in group II(n=25), 2 cases(8%) in group III(n=25) were complained of pruritus. Bradycardia and hypotension were observed in group IV(n=20) (each 1 cases, 5%). Conclusons : It is suggested from the above results that the morhine group during caudal anesthesia can produce more prolonged duration of analgesia. (Korean J Anesthesiol 1997; 32: 91∼96)

        외래환자 마취시 Propofol-fentanyl 과 Propofol-N2O 의 비교

        김경중,김진윤,라은길,박선규 대한마취과학회 1997 Korean Journal of Anesthesiology Vol.33 No.3

        Background : The choice of anesthetic agents and adjuvants during outpatient surgery is of critical importance. Propofol is widely used for the induction and maintenance of outpatient anesthesia. Because propofol lacks analgesic properties, very high concentrations may be required when propofol is used as the sole anesthetic drug. Propofol is used with adjuvants such as nitrous oxide or opioid. This study was designed to evaluate the intraoperative hemodynamic response, recovery characteristics and side effects of propofol-fentanyl anesthesia compared with propofol-N2O anesthesia for outpatient surgery. Methods : Twenty six healthy and unpremedicated patients scheduled for outpatient surgery were randomly allocated to receive either propofol-N2O anesthesia(N-group) or propofol-fentanyl anesthsia (F-group). The patients in N-group were ventilated with nitrous oxide 60∼70% in oxygen and the patients in F-group were ventilated with oxygen 40% in nitrogen via laryngeal mask airway(LMA). Results : There was no sinificant difference in blood pressure during anesthesia, recovery time and side effects between two group. There was significant decrease of heart rate in F-group. Conclusion : We concluded that nitrous oxide and fentanyl are reasonable adjuvants of propofol anesthesia in outpatient anesthesia. (Korean J Anesthesiol 1997; 33: 441∼446)

        제왕절개술에서의 Propofol-Fentanyl, Propofol-Ketamine 마취와 Propofol-아산화질소 마취의 적용

        오수원,구길회,라은길,권종필 대한마취과학회 1999 Korean Journal of Anesthesiology Vol.36 No.1

        Background: According to the increasing rate of cesarean section, the efforts of seeking safer and more satisfactory obstetric anesthesia techniques have been continued. Propofol, 2,6 di-isopropyl phenol, is a relatively new intravenous anesthetic agent and has been used for induction and maintenance for total intravenous anesthesia (TIVA). Authors examined the anesthetic technique using following anesthetics combinations; N2O-propofol, fentanyl-propofol, ketamine-propofol and made comparison of these ones for intraoperative hemodynamic stability, maternal and fetal safety. Methods: Sixty patients (ASA physical status 1 or 2) scheduled for cesarean section were randomly allocated into three groups, group N (propofol-N2O, n=20), group F (propofol-fentanyl, n=20), group K (propofol-ketamine, n=20). We checked the changes of blood pressure and heart rates during operation, anesthetic induction time, neonatal status (Apgar score, umbilical vein blood gas analysis), presence of intraoperative awareness and recovery time. Results: No significant differences in intraoperative hemodynamic changes, induction time and baby status. Total propofol dosages were greater in group N than group K (p<0.05) and maternal recovery time was prolonged in group K than group N or F (p<0.05). Conclusions: Anesthetic management using propofol-N2O or propofol-fentanyl or propofol-ketamine for cesarean section would provide satisfactory anesthesia without significant adverse effects to both mother and fetus.
