title: Sequential forearm intravenous regional and infiltration anaesthesia: value for haemostasis.
abstract: Intravenous regional anaesthesia using 0.5% lignocaine with a forearm tourniquet is a satisfactory technique for operations on the distal forearm, wrist and hand. Since recovery of pain sensation is rapid, haemostasis after release of tourniquet becomes difficult and sometimes impossible. Local wound infiltration or metacarpal block with 1% lignocaine just before release of the tourniquet can allow subsequent haemostasis and wound closure to be carried out without causing pain. 55 patients received this sequential forearm intravenous regional and infiltrative anaesthesia. Subsequent haemostasis and wound closure could be carried out without pain in 51 patients (92.7%); three patients (5.5%) noticed mild discomfort but the operations could be finished without any additional anaesthetic agent. No complications were encountered with this modified technique.
