경막외 Morphine의 첨가제로 사용한 Fentanyl과 Bupivacaine의 술후 진통효과 비교
안선연(Sun Yeon An),손 용(Yong Son),정영표(Young P 대한통증학회 1997 The Korean Journal of Pain Vol.10 No.2
N/A Backgound: The present study was undertaken to determine whether fentanyl or bupivacaine is a better adjuvant to epidural morphine with respect to postoperative analgesic use and with fewer incidence of side effects. Methods: We evaluated the clinical effects in 62 patients having cesarean section, divided in 3groups randomly. Group I(n 19) was received epidural marphine 4 mg, group II(n=22) was received epidural morphine 2 mg plus fentanyl 50 μg and group III(n=21) was received morphine 2 mg plus 0.25% bupivacaine 10 ml epidurally. We measured the first request time of analgesic for postoperative pain, the number of supplemental analgesics within 24 hours and the incidence of side effects postoperatively. Results: The first request time of analgesic for postoperative pain was significantly shorter in group III than in group I and IL The analgesic use in the first 24 hours was significantly more in group III than in group I and II. The side effects were significantly fewer incidence in group II than in group I and III. Conclusions: In conclusion, the combined use of epidural morphine and fentanyl provided better analgesia than the combined of epidural morphine and bupivacaine.

There has not been particular attention focused on the comparative benefits and risks of propofol anesthesia with inhalation anesthesia in the operations of long duration. This study was assessed the anesthetic efficacy and the speed of recovery from propofol or enflurane anesthesia in patients undergoing the long term operations. The propofol group (n=25) receiver 2.0 - 2.5mg/kg propofol intravenously for the induction of anesthesia and followed by propofol infusion(6 - 12mg/kg/h). The enflurane group (n=25) was induced as the propofol group and followed by enflurane(1-2 MAC) addministration. All patients received nitrous oxide (50%) in oxygen immediately after tracheal intubation. All anesthetic agents were stopped at the time of last stitch. The hemodynamic changes were recorded and the recovery was assessed with the time from discontinuation of all anesthetics to extubation and the indices of consciousness at early recovery(recall name, eye opening on command, raise hand on request and coughing on request). The recovery tests showed no differences between the groups. Systolic pressure after intubation in propofol group was significantly increased (p<0.05), compared with enflurane group. In propofol group, seven patients received fentanyl because of light anesthetic depth. The frequency of nausea and vomiting was similar between the groups. In conclusion, the long propofol anesthesia was not associated with faster recovery than enflurane anesthesia and propofol as an agent of anesthetic maintenance was unfavorable.

Background : There were several studies for the incidence of gastroesophageal reflux associated with the laryngeal mask airway(LMA), but the results of those studies were much different from one another. This conflicting results may be due to the time of the removal of LMA, which has been usually after the arousal(when the patient can open the mouth on command). So, the authors investigated the incidence of the gastroesophageal reflux and the regurgitation of gastric contents above the upper esophageal sphincter associated with the difference of the time of the removal of LMA. Methods : Sixty three patients scheduled for elective orthopedic surgery with a standardized general anesthetic technique were allocated randomly to Group A(n=34, LMA was removed when the rejection signs such as struggle, restlessness, swallowing and cough came out.) or Group B(n=29, LMA was removed after arousal). For the detection of reflux and regurgitation episodes during anesthesia, a pH monitoring probe was positioned in the lower esophagus and a methylene blue(50 mg) gelatine capsule was swallowed just before induction. At the end of anesthesia, the episodes of reflux and regurgitation of gastric contents were analyzed according to the pharyngeal blue staining or pH≤4. Results : The incidence of reflux(pH≤4) from the time of the rejection signs to the removal of LMA and the total incidence of reflux in Group B were significantly higher than that of Group A. No patient in both group showed pharyngeal staining of methylene blue. There was no clinical evidence of aspiration of gastric contents in either group. Conclusion : Maintenance of LMA until the patient can open the mouth on command seems to increase the incidence of the gastroesophageal reflux. (Korean J Anesthesiol 1998; 34: 956∼960)
