[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%.

A new device for continuous axillary plexus block is described. Using the "loss-of-resistance"-method as in peridural anesthesia it allows a safe introduction of a catheter within the neurovascular axillar sheath. ⋯ The main field of application for this device is seen in the management of pain postoperatively, mobilisation of contracted joints as well as in sympathetic block for peripheral vascular disease of various etiology. Furthermore, its allows the anaesthesia of the axillary plexus for operations of long duration (i.e. plastic surgery).
