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
Intercostal nerve blockade producing analgesia after appendicectomy.
Intercostal nerve blockade of the 10th, 11th and 12th thoracic nerves on the right side was compared with i.m. papaveretum as analgesia after appendicectomy. Patients with intercostal nerve blockade had significantly less pain at 0, 4, 8 and 12 h after operation and required less papaveretum (mean 0.26 mg kg-1/24 h) compared with the controls (mean 0.62 mg kg-1/24 h). There were no complications in either group. Intercostal nerve blockade may provide better quality analgesia following appendicectomy than i.m. papaveretum alone.

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.

Randomized Controlled Trial Clinical Trial
Effects of posture and baricity on spinal anaesthesia with 0.5% bupivacaine 5 ml. A double-blind study.
In four groups of 10 patients, 0.5% bupivacaine 5 ml was used in spinal anaesthesia for gynaecological surgery. Group 1 received plain solution in the sitting position, group 2 plain solution in the lateral position, group 3 hyperbaric solution in the sitting position and group 4 hyperbaric solution in the lateral position. All patients were returned to the horizontal supine position, the sitting subjects 2 min after, and the lateral subjects immediately after, spinal injection. ⋯ There was, however, considerable scatter within each group. Posture had some effect on the speed of onset of the analgesia, but no significant effect on the final outcome. The use of 0.5% bupivacaine as a test dose in extradural blockade is discussed.
