Randomized Controlled Trial Comparative Study Clinical Trial
ICI 35868 (Diprivan): a new intravenous induction agent. A comparison with methohexitone.
ICI 35868 (Diprivan) has been used as an induction agent in patients undergoing minor gynaecological surgery and as the sole anaesthetic agent during bronchoscopy, and its effects were compared with those of methohexitone. The new agent proved to be satisfactory, although induction of anaesthesia was significantly longer than following methohexitone. complications were similar with both drugs. ICI 35868 deserves full investigation as an intravenous anaesthetic agent.

This is a report of a case of inadvertent release of an arm tourniquet only 5 minutes after intravenous regional anaesthesia with 150 mg of bupivacaine without serious effect.

Randomized Controlled Trial Comparative Study Clinical Trial
Maternal opinion about analgesia for labour. A controlled trial between epidural block and intramuscular pethidine combined with inhalation.
In a randomised controlled trial epidural analgesia with bupivacaine 0.5% (mean dose 112.8 mg) was compared with pethidine (mean dose 200 mg) and inhalational analgesia in primipara (28 and 30 mothers) and multipara (17 and 18 mothers). Mothers who had an uneventful pregnancy and labour and agreed to have either treatment were studied during labour and followed-up at interviews for 5 months after delivery. Epidural block was rated significantly superior in respect of pain relief and comfort, there were no differences between the groups in reports of perineal discomfort. ⋯ Very few mothers, in each group, reported something missing in their experience of childbirth. Two thirds of each group would use the same method again. Epidural block can therefore be recommended to uncommitted mothers as a satisfying and effective method of pain relief for labour.

Randomized Controlled Trial Comparative Study Clinical Trial
ICI 35868 (Diprivan): a new intravenous anaesthetic. A comparison with Althesin.
ICI 35868 (Diprivan), 1-2 mg/kg was used to induce anaesthesia in 20 patients, and the results compared with induction of anaesthesia by Althesin 0.5 ml/kg given to a similar group of 20 patients. ICI 35868 was effective in inducing anaesthesia, but produced more respiratory depression, and cardiovascular effects which were significantly different from those produced by Althesin. ICI 35868 gave a smoother induction. It is concluded that ICI 35868 is a promising new induction agent which may also find application for the maintenance of anaesthesia.

Randomized Controlled Trial Comparative Study Clinical Trial
Anaesthesia for surgical correction of fractured femoral neck. A comparison of three techniques.
Sixty patients with fractured neck of femur and scheduled for surgical correction were randomly allocated to receive one of three anaesthetic techniques: general anaesthesia; spinal analgesia; psoas compartment block. The patients in the local anaesthetic groups also received a light general anaesthetic. There was little difference in the pre-, intra- and postoperative events, and no difference in postoperative mortality.
