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.

Randomized Controlled Trial Clinical TrialLow-dose ketamine infusion for analgesia during postoperative ventilator treatment.
In a randomized, double-blind study with placebo, ketamine was used as an analgesic during ventilator treatment in the period of recovery after major abdominal surgery. Forty patients were orally intubated and ventilated by means of a volume-controlled ventilator. Twenty of them received an i.v. bolus of 30 mg of ketamine followed by an 8-h infusion of 1 mg per minute. ⋯ Dreams and hallucinations were recalled in three patients in the control group and five in the ketamine group. Only one control and two ketamine patients experienced these as unpleasant. In this investigation, ketamine infusion in a low dose appeared to offer satisfactory analgesia and to permit tolerance of the orotracheal tube.

Randomized Controlled Trial Clinical TrialAnaesthetic temperature and shivering in epidural anaesthesia.
The mechanism of shivering during epidural analgesia remains unclear. This study investigates the role of the temperature of the local anaesthetic injected extradurally. Forty patients admitted for elective caesarean section under epidural anaesthesia were studied; 20 were given bupivacaine warmed to 37 degrees C (warm group) and 20 were given bupivacaine stored at 4 degrees C (cold group); the occurrence of shivering in both groups was recorded. ⋯ This difference was statistically significant (P less than 0.03). The results suggest that there are thermosensory mechanisms in the human spinal canal. In our view, epidural anaesthetic solutions should be warmed to body temperature prior to injection to reduce the incidence of shivering.
