The use of a low-power nerve stimulator to aid nerve location during the performance of sciatic nerve block was compared with a conventional anatomically based technique. The success rate, both in terms of the production of an effective block and the duration of postoperative analgesia, was significantly higher in the stimulator groups than in the non-stimulator groups. The implications of the study for both clinical and teaching practice are discussed.

Randomized Controlled Trial Clinical Trial
Postoperative headache in young patients after spinal anaesthesia.
Spinal anaesthesia was performed on 247 young adult patients with a 25-G needle. Rectal administration of indomethacin had no significant effect on the incidence of postdural puncture headache, which occurred in 16.8% of patients who received the drug compared to 24.5% who received a placebo. A history of headache pre-operatively did not influence the incidence of postlumbar puncture headache.

An historically prospective study of the rates of early retirement due to permanent ill health, early retirement between 60 and 64 years of age for other reasons, and deaths while in post, among consultant anaesthetists in England was carried out. The control group comprised consultants in four other hospital specialty groups. Approximately two-thirds of all consultants employed in the five specialties at National Health Service hospitals in England during 1966-83 were included in the study. ⋯ The number of deaths in post was also raised. For the smaller group of female anaesthetists there was not a statistically significant excess of ill-health retirements, but the number of early retirements between 60 and 64 was significantly greater than expected (p less than 0.005), as was the number of deaths in post (p less than 0.001). Possible causes of these excesses are discussed.
