Midlatency auditory evoked potentials during anaesthesia with increasing endexpiratory concentrations of desflurane.
Under general anaesthesia with the volatile anaesthetics halothane, enflurane and isoflurane, midlatency auditory evoked potentials (MLAEP) are suppressed dose-dependently. Therefore, MLAEP have been used to measure depth of anaesthesia and to indicate intraoperative awareness. Desflurane is a new volatile anaesthetic and its effect on MLAEP have not been studied previously. ⋯ Based on these observations, endexpiratory concentrations of > or = 4.5 vol % desflurane should suppress awareness phenomena such as auditory perceptions during anaesthesia.

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.

Infants with Beckwith-Wiedemann syndrome usually present different abnormalities which may require surgical correction. Anaesthetic management may be complicated by abnormal airway anatomy, congenital heart disease and severe hypoglycaemia. Careful preoperative evaluation, perioperative monitoring and suitable choice of anaesthetic technique are required for a successful outcome. We report the perioperative management of a patient with Beckwith-Wiedemann syndrome presenting for omphalocoele surgery on his first day of life and for bilateral inguinal hernia repair four months later.

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.

Comparative StudyRecovery of psychomotor function following general anaesthesia in children: a comparison of propofol and thiopentone/halothane.
The present study was undertaken to compare immediate recovery and recovery of complex psychomotor function in 20 children (aged 6-12 years) following general anaesthesia with either thiopentone/halothane or propofol. Early recovery of psychomotor skills was significantly faster in the propofol group than in the thiopentone/halothane group. ⋯ The results indicate that the recovery of psychomotor function in paediatric patients following general anaesthesia with propofol is significantly faster than with thiopentone/halothane. This has important implications for parental satisfaction, the time over which patients need to be monitored in the recovery room and for the discharge criteria after daycase surgery.
