Randomized Controlled Trial Clinical Trial
[Does the difference in anesthetic methods influence postoperative nitrogen balance?].
To evaluate the influence of anesthesia on postoperative nitrogen balance after upper abdominal surgery, twenty-seven patients undergoing the surgery were investigated. They were allocated randomly to three groups receiving different anesthetic methods, i.e., epidural anesthesia, general anesthesia or balanced anesthesia. In the epidural anesthesia group, anesthesia was maintained with 0.5% isoflurane, nitrous oxide and oxygen supplemented with epidural analgesia extending from Th 1 to L 3. ⋯ Postoperative values of IL-6 and CRP also did not differ significantly among the three groups. Postoperative WBC was significantly higher in the balanced anesthesia group than in other two groups. The results suggest that the difference in anesthetic methods does not influence postoperative nitrogen balance.

[Study on combined acupunctural and general anesthesia in pneumonectomy].
Combined acupunctural and general anesthesia in pneumonectomy were studied. The result showed that general anesthesia complemented with electro-acupuncture at He Gu (LI 4) and San Yang Luo(SJ 8) reduced amount of Fentanyl 38-85 micrograms/h compared with general anesthesia alone. ⋯ It was considered that acupuncture in combination with general anesthesia could reduce dosage of anesthetics and the inhibition of physiological function. It is a practical and acceptable anesthetic method by the surgeon and patient.

Comparative Study
[Cost effectiveness of local regional anesthesia in a remote area].
Loco-regional anesthesia techniques are considered as a simple and economic solution to problems posed by anesthesia in developing countries. However the cost benefits of some techniques are reduced by cardiovascular effects that affect the quantity and nature of peroperative vascular filling usually necessary during general anesthesia. The purpose of the present study was to ascertain the relative costs of these methods by comparing the quantity of crystalloid solution and blood administered during loco-regional anesthesias and general anesthesias in a general hospital center in Africa. ⋯ These findings indicate that loco-regional anesthesia performed under standardized conditions does not significantly change the quantity and nature of preoperative filling usually necessary during general anesthesia. Thus these techniques can be considered as cost-effective in developing countries even though the long period necessary for practitioners to learn them results in a transient increase in cost. A prospective study by surgical groups with experience using loco-regional anesthesia is needed to confirm this study.

Randomized Controlled Trial Comparative Study Clinical TrialTherapeutic suggestion has not effect on postoperative morphine requirements.
This study was designed to confirm the effect of therapeutic intraoperative auditory suggestion on recovery from anesthesia, to establish the effect of preoperative suggestion, and to assess implicit memory for intraoperative information using an indirect memory task. Sixty consenting unpremedicated patients scheduled for elective gynecologic surgery were randomly divided into three equal groups: Group 1 received a tape of therapeutic suggestions preoperatively, and the story of Robinson Crusoe intraoperatively; Group 2 heard the story of Peter Pan preoperatively and therapeutic suggestions intraoperatively; Group 3 heard the Crusoe story preoperatively and the Peter Pan story intraoperatively. A standardized anesthetic technique was used with fentanyl, propofol, isoflurane, and nitrous oxide. ⋯ No indirect memory for the Crusoe story could be demonstrated. This study did not confirm previous work which suggested that positive therapeutic auditory suggestions, played intraoperatively, reduced PCA morphine requirements. In contrast, a positive implicit memory effect was found for a story presented intraoperatively.

Randomized Controlled Trial Comparative Study Clinical TrialRenal and hepatic function in surgical patients after low-flow sevoflurane or isoflurane anesthesia.
The safety of low-flow sevoflurane anesthesia, which produces higher concentrations of toxic compounds, has been questioned. One hundred surgical patients received sevoflurane or isoflurane anesthesia at a total flow rate of 1 L/min. End-tidal CO2 concentrations and inspired and end-tidal anesthetic concentrations were monitored during anesthesia. ⋯ In both groups, total bilirubin, direct bilirubin, aspartate aminotransferase, and alanine aminotransferase were increased postoperatively. There was no difference between groups. Low concentrations of Compound A were present in low-flow sevoflurane anesthesia, but no significant differences in clinical laboratory values were observed between low-flow sevoflurane and isoflurane anesthesia.
