Clinical evaluation of etidocaine in continuous caudal analgesia for pelvic floor repair and post-operative pain relief

Abstract

A randomized double-blind trial compared 1-0% etidocaine and 1-5% lignocaine (both with 1/200,000 adrenaline), for caudal anaesthesia for pelvic floor repair. Etidocaine was highly effective for the surgical procedure, with rapid onset of action, adequate muscle relaxation and longer duration of action. Its use for post-operative analgesia may be hindered by the concomitant immobilization of the legs. The problem of tachyphylaxis with etidocaine needs further investigation.
