A Comparative Study of Analgesic Efficacy of Intrathecal Bupivacaine with Ketamine Versus Bupivacaine with Magnesium Sulphate in Parturients Undergoing Elective Caesarian Sections.

Background And Aims: Spinal anaesthesia is the most preferred technique of anaesthesia in parturient, undergoing lower segment caesarean sections (LSCS) which provides effective pain relief during intra operative and early postoperative period. However, recent studies demonstrate that about 50%-70% of patients experience moderate to severe pain after LSCS indicating that postoperative pain remains poorly managed. The aim of our study was to compare intrathecal magnesium sulphate (Mgso4) and ketamine as adjuvants to hyperbaric bupivacaine in parturients posted for elective caesarean sections under spinal anaesthesia to determine their effectiveness in extending the duration of analgesia.
