Randomized Controlled Trial Comparative Study Clinical Trial
General anaesthesia versus epidural anaesthesia for primary caesarean section--a comparative study.
Forty-seven healthy parturients undergoing elective Caesarean section were randomly allocated to either general anaesthesia (n = 24) or epidural anaesthesia (n = 23) under standardized anaesthetic and surgical conditions. Seven women of the epidural group required additional systemic analgesia or sedation following delivery of the neonate. Nine of 24 newborns obtained 1-min Apgar scores below 7 after general anaesthesia compared to only 3/23 after epidural anaesthesia. ⋯ Our investigation did not show either the incision-delivery interval or the start of operation-delivery interval to play a role in neonatal outcome. Epidural anaesthesia is superior to general anaesthesia in Caesarean section under normal conditions with regard to neonatal outcome. Whether this is also true for critical conditions cannot be concluded from this study.

Randomized Controlled Trial Clinical Trial
Thoracolumbar epidural anaesthesia and isoflurane to prevent hypertension and tachycardia in patients undergoing abdominal aortic surgery.
Cardiovascular and hormonal responses to reconstructive abdominal aortic surgery were studied in 20 patients anaesthetized either with moderate-dose fentanyl (20 micrograms kg-1) combined with isoflurane, nitrous oxide and oxygen (n = 10), or with thoracolumbar epidural bupivacaine combined with isoflurane, nitrous oxide and oxygen (n = 10). After the start of operation, hypotension occurred in four patients in the epidural group. In both groups, the aortic cross-clamping caused slight increases both in mean arterial pressure and in calculated systemic vascular resistance, and a significant decrease in cardiac index. ⋯ At the same time, plasma vasopressin and adrenaline increased significantly in both groups, whereas plasma noradrenaline did so only in the fentanyl group. The results suggest that thoracolumbar epidural bupivacaine combined with low-dose isoflurane in nitrous-oxide-oxygen prevents intra-operative hypertension and tachycardia, but it may cause hypotension. Post-operative hypertension and tachycardia as well as the increase in plasma noradrenaline are prevented by epidural administration of bupivacaine-fentanyl.

Randomized Controlled Trial Comparative Study Clinical Trial
Total intravenous anaesthesia with propofol or etomidate.
In combination with fentanyl, propofol was compared with etomidate for total intravenous anaesthesia in 21 women (ASA Grades I-II) admitted for elective hysterectomy. They received either propofol (bolus 1.5 mg kg-1, infusion 9 mg kg-1 h-1 for 10 min thereafter 6 mg kg-1 h-1) or etomidate (bolus 0.10 mg kg-1, infusion 3 mg kg-1 h-1 reduced to 0.6 mg kg-1 h-1). Fentanyl 10 micrograms kg-1 was given for induction followed by an infusion of 30 micrograms kg-1 h-1 for 10 min reduced to 6 micrograms kg-1 h-1 for the first hour and successively reduced over time. ⋯ Nausea and vomiting were more pronounced in the etomidate group, and mental side-effects were only seen after etomidate. After 3 months, more patients in the etomidate group complained of reduced power of concentration. We conclude that total intravenous anaesthesia with either propofol or etomidate is equally easy to manage, but in the recovery situation propofol was advantageous in time and quality.

Randomized Controlled Trial Comparative Study Clinical Trial
Post-operative analgesia following femoral-neck surgery--a comparison between 3 in 1 femoral nerve block and lateral cutaneous nerve block.
A prospective controlled randomized trial on patients receiving surgery for fractured neck of femur was carried out, in which post-operative analgesic requirements in three separate groups were compared. Patients in Group 1 acted as controls, whilst those in Groups 2 and 3 received lateral cutaneous nerve blocks and 3 in 1 femoral nerve blocks, respectively. Patients in Group 3 needed significantly less analgesia than the other two groups, and the time to first administration of analgesia was significantly longer. No complications of either of the nerve blocks was noted.

Randomized Controlled Trial Clinical Trial
Is the diagnosis of significant residual neuromuscular blockade improved by using double-burst nerve stimulation?
Although DBS is more sensitive than TOFC, manual assessment of DBS fade can only detect residual paralysis at TOF ratio < 0.7.
