Randomized Controlled Trial Clinical Trial
Efficacy of a nerve stimulator in regional analgesia; experience in a resident training programme.
Forty interscalene brachial plexus regional blocks and twenty sciatic-femoral lower limb blocks were performed by 1st and 2nd year anaesthesia residents. Nerve trunk location was equally but randomly divided between use of a peripheral nerve stimulator and reliance on paraesthesiae. ⋯ It is concluded that the stimulator is not a useful adjunct for nerve location, except in those patients who are unable to co-operate in eliciting paraesthesia. In such patients the stimulator permits a comparable success rate.

Randomized Controlled Trial Comparative Study Clinical Trial
[Axillary plexus block with long-acting local anaesthetics (a comparative study of etidocaine and bupivacaine) (author's transl)].
Brachial and axillary plexus blockade was carried out on volunteers using a mixture of etidocaine 1% with adrenaline, and bupivacine 0,5% with adrenaline. Both drugs are long-acting local anaesthetics. ⋯ With the latter motor blockade seems to be more strongly influenced and significantly outlasts sensory sympathetic nerve block. The results and findings of other authors are discussed, and whether the different behaviour of the 2 long acting local anaesthetics in this context implies a different affinity of the drugs to the different types of nerves.

Randomized Controlled Trial Comparative Study Clinical Trial
Effect of intercostal nerve blockade during operation on lung function and the relief of pain following thoracotomy.
The use, during operation, of intercostal nerve blocks with lignocaine and bupivacaine for the relief of pain following thoracotomy was assessed in 138 patients. Irrespective of the method used to evaluate efficacy, it was not possible to demonstrate a lasting effect of clinical significance favouring either local anaesthetic agent. This form of treatment, although free from serious side effects, had no beneficial effects on lung function and is not recommended for the relief of pain following surgery.

Randomized Controlled Trial Clinical TrialThe shape of the amniotic pressure curve before and after paracervical block during labour.
Paracervical block (PCB) given during labour reduces the uterine activity necessary for cervical dilatation. The aim of the present investigation was to find out whether this effect of PCB changes the form of the amniotic pressure curve. A preliminary investigation showed that the ascending limb of the amniotic pressure curve, A, consists of three phases. ⋯ The changes typical of PCB did not occur after epidural block. The discovery of the six phases of the amniotic pressure curve, their change after PCB and the results of other investigators make possible a suggestion of the basic physiological processes that influence amniotic pressure during coordinated labour contractions. It is held that the form of the amniotic pressure curve can be explained in terms of contraction, relaxation, and propagation of a contraction and a relaxation wave.
