[The popliteo-femoral block, a rarely used form of regional anesthesia. With special reference to the use of peripheral nerve stimulators].
Blockade of the sciatic nerve in the fossa poplitea is a rarely used form of regional anaesthesia. A new method of identification of the tibial and peroneal nerve and their blockade in combination with blockade of the femoral nerve using a peripheral nerve stimulator, is described. Results in 300 patients during a 12 month period are described and discussed.

[Identification of the peridural space with the infusion method in relation to the incidence of inadvertent puncture of the dura].
In 868 cases the identification of the epidural space was performed by plugging a running infusion drip. After accurate identification of the epidural space the patient received either 0.5% or 0.75% bupivacaine without adrenalin for operations on the lower extremities, at the perineum and for lower and upper abdominal surgery. Analgesia was adequate. ⋯ Thus the frequency of this complication was below 1%. This is - even according to the latest publications - quite a satisfactory result. An unidentified accidental dural puncture and associated complication did not occur.

Comparative Study[Comparative studies on general anesthesia versus peridural anesthesia in primary cesarean section].
In a prospective interdisciplinary study involving the departments of gynaecology, anaesthetics and paediatrics, the influence on both the mother and neonate of general as opposed to epidural anaesthesia was compared in 47 planned caesarean sections. Neither maternal or foetal risk factors were present in these cases, and the cardiotocogram was always normal before the anaesthetic was applied. Methods. ⋯ Acid-base and PCO2 values were not markedly influenced by either of the techniques used, but the maternal capillary PO2 levels were very much higher in the general anaesthetic group. The neonates born under general anaesthetic had a lower 1 min Apgar score, as a result of the relatively long induction-delivery time, of on average 17 min. The 5 and 10 min Apgar scores and the neurophysiological development of the babies revealed no differences between the two groups.

[Position of the spinal cord and the depth of the peridural space as a function of spinal column kyphosis and age].
A dry tap may occur when performing a spinal anaesthetic, especially when there is an extreme kyphosis. The puncture can be at normal level or higher. ⋯ This fact is especially important in anatomical length variations of the medulla spinalis. If all the causes for a dry tap are borne in mind then this can easily be prevented by a simple manoeuvre, which we describe in the text.

[Modification of axillary plexus block with the loss-of-resistance method using a blunt needle].
A modification of the method of brachial plexus block is described using the "loss of resistance"-test and a needle with an extra short 45 degrees bevel (the Crawford bevel). This report is presented firstly to describe this needle and secondly because it is not necessary to search for paraesthesiae before injecting. ⋯ The initial failure rate was 3.7%, but a second attempt was successful in 2.3% to give an overall failure rate of 1.4%. No nerve injuries were observed and troublesome haematomas from accidental puncture of the artery were 2.7%.
