Ten obstetric patients received 17-20 ml of autologous blood through an extradural catheter after inadvertent dural puncture. The time interval from dural puncture to prophylactic extradural blood patch ranged from 90 to 660 min. One of the 10 patients developed a mild occipital headache, which required no further intervention.

Randomized Controlled Trial Comparative Study Clinical Trial
Extradural bupivacaine or lignocaine anaesthesia for elective caesarean section: the role of maternal posture.
Extradural anaesthesia was induced in 64 patients in either the sitting or the lateral position, for elective Caesarean section with either 0.5% plain bupivacaine or 2% lignocaine with adrenaline 1 in 200,000. Onset was significantly shorter and a significantly greater number of patients were ready for surgery within 35 min following injection of lignocaine in the lateral position. ⋯ Significantly more patients who had received the first injection of local anaesthetic agent in the sitting position required ephedrine to correct maternal hypotension. Most frequently, hypotension coincided with transfer of patients to theatre and thus was associated with movement of the patient in the presence of extensive sympathetic block.

Randomized Controlled Trial Clinical Trial
Learning fibreoptic intubation: use of simulators v. traditional teaching.
This study compared a graduated training programme with that of a traditional teaching method to facilitate the learning of the technique of fibreoptic nasotracheal intubation. Thirty-two anaesthesia trainees were randomly assigned to two groups. ⋯ Nasotracheal intubation was accomplished significantly more often by the trainees in the graduated programme (86 out of 96 (89.6%) v. 64 out of 96 (66.5%) (P less than 0.01). The results demonstrate that trainees who undergo a graduated training programme using simulators are initially more successful at awake fibreoptic nasotracheal intubation than those who have learned in the traditional manner, and that the conditions of the investigation were acceptable to the trainees and patients.
