A CONTROLLED AND RANDOMIZED STUDY OF COMPARING ANAESTHETIC EFFICACY OF INTRATHECAL NALBUPHINE HYDROCHLORIDE WITH BUPIVACAINE AND BUPIVACAINE ALONE FOR INFRAUMBILICAL SURGERIES:A PROSPECTIVE STUDY

Abstract

Over the years, the technique has been refined and has evolved into the modern concept of intrathecal, spinal or subarachnoid block. Spinal effects are produced by slow injection of a small volume of local anaesthetic solution containing dextrose (to make it hyperbaric).Among the regional techniques available, spinal anaesthesia is an attractive option when the surgical site is below umbilicus.
