The use of a halothane meter in routine paediatric anaesthesia with controlled ventilation is described. The results demonstrate the accuracy achieved in the control of the alveolar halothane concentration. Measurement of the alveolar halothane concentration revealed responses to surgical stimulation otherwise obscured by neuromuscular blockade, and this may indicate insufficient depth of anaesthesia.

Clinical Trial Controlled Clinical Trial
Effect of Diazepam at the neuromuscular junction. A clinical study.
In patients undergoing surgery under general anaesthesia diazepam 0.16 mg kg-1 had no effect on mechanical twitch height of the adductor pollicis muscle of the thumb when the ulnar nerve was stimulated at the wrist. The muscle responses were evoked by single, repeated supramaximal stimuli at 0.2 Hz and "train-of-four" stimulation at 2 Hz for 2 s. Diazepam 0.16 mg kg-1 had no effect on the depth or recovery of neuromuscular blockade produced by suxamethonium, tubocurarine, pancuronium, fazadinium or alcuronium.

Randomized Controlled Trial Comparative Study Clinical Trial
Nefopam in postoperative pain.
Three comparable groups of surgical patients were given nefopam 0.2 mg kg-1 or 0.4 mg kg-1 or morphine 0.15 mg kg-1 for pain relief after operation. Nefopam 0.4 mg kg-1 was equi-analgesic with morphine 0.15 mg kg-1 and produced no obvious cardiovascular or respiratory side-effects.
