Abstract |
A modification of an i.v. regional anaesthesia (IVRA) technique is described in which the arm is re-exsanguinated before surgery (re-IVRA). IVRA and re-IVRA were compared for quality of operative field, sensory and motor block, quality of analgesia and blood concentrations of prilocaine, lignocaine and mepivacaine in a double-blind study in 120 patients undergoing hand surgery. Re-IVRA provided a significantly better surgical field without affecting sensory or motor block. Re- exsanguination improved tolerance of the tourniquet. Plasma concentrations in the re-IVRA group showed some increases, but these were not in the toxic range.
