Comparison between Single Injection Transthecal and Subcutaneous Digital BlocksFrom the Department of Orthopaedic Surgery, Tan Tock Seng Hospital, Singapore Correspondence: Dr Low Chee Kwang, Department of Orthopaedic Surgery, Tan Tock Seng Hospital, Moulmein Road, Singapore 308433. A randomized double blinded study was performed on 142 patients to evaluate two different techniques of single injection digital anaesthesia. In group A, 86 digits in 71 patients were anaesthetized by a single injection transthecal technique using 3 cc of lignocaine and bupivacaine mixture. Anaesthesia of the whole digit was achieved in 83 (97%) digits. In group B, 80 digits in 71 patients were anaesthetized with a single injection subcutaneous technique using the same amount of anaesthetic mixture. Total anaesthesia of the digit was achieved in 75 (94%) digits. These two techniques were found to have no differences in effectiveness, distribution, onset and duration of anaesthesia.
