Randomized Controlled Trial Clinical TrialPropofol emulsion for induction and maintenance of anaesthesia. A combined technique of general and regional anaesthesia.
To provide general anaesthesia with endotracheal intubation during regional blockades, three dose regimens of propofol emulsion were studied: induction 2 mg kg-1, infusion rate 9 mg kg-1 h-1 (Group 1); induction 2.5 mg kg-1, infusion rate 12 mg kg-1 h-1 (Group 2); induction 2.5 mg kg-1, infusion rate 9 mg kg-1 (Group 3). Each group comprised 10 healthy (ASA class 1 or 2) unpremedicated patients. The induction times measured from the start of injection until counting ceased (+/- 50 s) and until eye-lash reflex disappeared (+/- 80 s) showed no statistical differences between groups. ⋯ Apart from a short period of euphoria, recovery was uneventful. There was no tendency to fall asleep again. None of the combinations of induction doses and infusion rates provided good anaesthesia conditions for an acceptable number of patients.

Randomized Controlled Trial Clinical TrialHalothane, enflurane and isoflurane anaesthesia for adenoidectomy in children, using two different premedications.
In 48 children subjected to adenoidectomy, comparisons of airway problems, heart rates, cardiac arrhythmias, ventilation and stress hormone reactions were studied during halothane, enflurane and isoflurane anaesthesia. Sixteen children were anaesthetized with either of the three agents and eight patients in each group received diazepam 0.25 mg kg-1 and atropine 0.015 mg kg-1 rectally (DA) as premedication and the remainder diazepam 0.5 mg kg-1, morphine 0.15 mg kg-1 and scopolamine 0.01 mg kg-1 (DMS) rectally. All children were intubated and breathing spontaneously. ⋯ Plasma ACTH and cortisol were similar with all three agents. During induction of anaesthesia in the DA-premedicated halothane group, however, plasma catecholamines were higher than in the group which received DMS, in contrast to the findings during enflurane and isoflurane anaesthesia. The DMS premedication decreased the response of plasma ACTH, cortisol and plasma catecholamines to surgery.

Randomized Controlled Trial Clinical TrialEvaluation of the efficacy of elastic compression stockings in prevention of hypotension during epidural anaesthesia for elective caesarean section.
The ability of graduated compression elastic stockings to prevent hypotension during elective epidural caesarean section was evaluated. Twenty women were randomly assigned to two groups of ten, one group being fitted with the stockings. The incidence and degree of hypotension were the same in both groups. Graduated compression elastic stockings are of no benefit in reducing the incidence of maternal hypotension during caesarean section.

Randomized Controlled Trial Comparative Study Clinical TrialThe effect of bupivacaine and morphine on pain and bowel function after colonic surgery.
Sixty patients scheduled for colonic surgery were randomly allocated to four groups according to postoperative pain medication: I. Control group, the patients received oxycodone intramuscularly (0.15 mg kg-1) on request. II. ⋯ Pain intensity (visual analogue scale) was lower in Groups II and III at 3 h and in Group IV at 24 h compared to the control Group I. All the epidurally treated groups needed less additional analgesics than the control Group I. Postoperatively bowel movements occurred on the second day in Group II (bupivacaine) as compared to the fourth day in all other groups (P less than 0.05).

Randomized Controlled Trial Comparative Study Clinical TrialPropofol vs thiopentone as anaesthetic agents for short operative procedures.
In a randomized open study, 120 healthy female patients were included. For short gynaecological procedures they were anaesthetized with either propofol 2.5 mg X kg-1 (n = 60) or thiopentone 5 mg X kg-1 (n = 60) in combination with nitrous oxide/oxygen (67%/33%). Supplementary doses of propofol (10-20 mg) or thiopentone (25-50 mg) were given when necessary during the procedure. ⋯ Otherwise, the side-effects were similar in both groups. We conclude that propofol is similar to thiopentone in its anaesthetic qualities during induction and maintenance of short anaesthetic procedures. Propofol was associated with a more rapid emergence from anaesthesia than thiopentone.
