[Differences in patient sensitivity to currently used non-depolarized curaremimetics and factors which affect it].
A whole number of factors which affect the depth as well as duration of the block after administration of non-depolarizing myorelaxants, both positively and negatively. However, the effect in one patient can be predicted only with difficulty--as this paper showed--as neither the hydration level, age nor kalemia concentration had any effect on the depth of the neuromuscular block. Neither in patients, otherwise healthy, is it possible to predict the degree of the neuromuscular block after administering a standard dose of curaremimetic. ⋯ The determination of the actual block depth can help to control relaxation according to the needs of the surgeon or anaesthesiologist, and according to the individual patient's sensibility. A different sensibility response to myorelaxants was found in pipecuronium, vecuronium and even in atracurium. It corresponds approximately to gaussian curve of frequency.

Comparative Study Clinical Trial Controlled Clinical TrialInterpleural administration of bupivacaine after cholecystectomy: a comparison with intercostal nerve block.
Pethidine requirements and verbal pain scores were recorded in 36 patients after cholecystectomy via subcostal incision. All patients also received 20 ml 0.5% bupivacaine with adrenaline 1/200,000. Group 1 (12 patients) received unilateral intercostal nerve blocks. ⋯ Small asymptomatic pneumothoraces were noted on chest X-ray in six of the 24 patients with interpleural catheters. Both types of local anaesthesia produced lower pain scores than pethidine alone (P less than 0.05) with 25% of intercostal nerve blocks and 63% of interpleural catheters requiring no pethidine in the following three hours. The provision of catheter 'top-ups' between six and 18 hours after surgery also resulted in lower pain scores and a reduction in pethidine requirements (P less than 0.05).

Randomized Controlled Trial Clinical Trial
Study of the effectiveness of bupivicaine infiltration of the ilioinguinal nerve at the time of hernia repair for post-operative pain relief.
The effect on post-operative pain relief and analgesic requirements of direct ilioinguinal nerve block using 0.5% bupivicaine (Marcain) at the time of hernia repair was studied. Sixty patients were randomly allocated into two groups, A and B, both being well matched for age, numbers and sex. Those in whom nerve block was used (Group A) required significantly less intramuscular opiates and strong oral analgesics (co-dydramol) than those who did not receive bupivicaine (Group B) during the first 24 hours post-operatively.
