AbstractA 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. This technique has the advantage of a much clearer "loss of resistance" on penetrating the neurovascular bundle. We have treated 219 patients using this technique and the blocks were given by both experienced staff and trainees. 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%.
