Randomized Controlled Trial Clinical Trial
Analgesia following femoral neck surgery. Lateral cutaneous nerve block as an alternative to narcotics in the elderly.
In a prospective controlled randomised trial on patients undergoing operative repair of fractured neck of femur via a lateral incision, the postoperative analgesic requirements of one group of patients who received a lateral cutaneous nerve block were compared with a second group who received no block. The former group were found to need significantly less intramuscular pethidine in the first 24 hours, and 44% required no supplementary analgesia whatsoever during this period. The time to first dose of opioid in the remainder was greatly increased. No untoward sequelae associated with the nerve block were seen.

Randomized Controlled Trial Clinical Trial
Mental function and morbidity after acute hip surgery during spinal and general anaesthesia.
Forty elderly patients (mean age 78.9 years) undergoing acute surgery for hip fracture were given at random either spinal analgesia with bupivacaine 0.75% or general anaesthesia with diazepam, fentanly and N2O/O2. Mental function was studied pre-operatively with an abbreviated mental test and 1 week and 3 months postoperatively in both groups. Mortality and number of complications was similar in the two groups, but a shorter time of ambulation was seen in the spinal group compared to the general anaesthetic group. No persistent impairment in mental function was found after acute hip surgery under spinal or general anaesthesia and the only advantage of regional technique was a shorter time of ambulation.

A case is reported of a 23-year-old man who became hypothermic within 4 hours of exposure. Full physical recovery occurred within 5 hours of an asystolic cardiac arrest using simple rewarming techniques.

The depth of the epidural space at different intervertebral interspaces was measured in 1000 parturients. Overall the median distance from the skin to the epidural space was 4.7 cm, but this varied with the lumbar interspace at which it was measured, being greatest at the third (L3-4) interspace (4.93 cm) and least at the first (L1-2) interspace (4.23 cm). The clinical significance of these findings is discussed.
