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.

Comparative Study Clinical Trial Controlled Clinical TrialA comparative study between etidocaine and bupivacaine in ulnar nerve block.
The long-acting local anaesthetics bupivacaine and etidocaine were compared in a double-blind study using ulnar nerve block. Eleven volunteers took part in the study. Solutions used were: bupivacaine 0.25% and 0.5% and etidocaine 0.5% and 1 %. ⋯ Differences were seen in the degree of motor block in favour of etidocaine. The sympathetic block seemed to be more intense and of longer duration with bupivacaine. Etidocaine had a shorter time of onset in all nerve fibres.

In this paper, a description is given of a simple, rapid method of peripheral nerve block by means of electrical nerve stimulation. This method gives optimal results and does not require cooperation by the patient. Since optimal sedation is permissible, the method is painless.

Comparative Study Clinical TrialAxillary plexus block with etidocaine.
Axillary plexus block has been used to compare 0.5% and 1.0% etidocaine (with adrenaline 5 mug/ml) in 32 patients in an open label study. The injected volume was 30 ml. The time to total analgesia and motor block was around 10-12 minutes. ⋯ The time from injection to return of total sensation and motility was 8.5-10 hours. Adequate analgesia was achieved in all patients but two (one in each group). No noteworthy differences were found between the two solutions.
