Intrathecal Morphine for Inguinal Hernia Repair.

The Comparison of Two Different Doses of Morphine Added to Spinal Bupivacaine for Inguinal Hernia Repair.

The aim of this study was to compare the effects of two different doses of intrathecal morphine (0.1 mg and 0.4 mg) combined with 7.5 mg of heavy bupivacaine on postoperative block regression times, postoperative analgesia and the severity of side effects, for inguinal hernia repairs.

The purpose of this study was to compare spinal anesthesia with low dose heavy bupivacaine combined with 0.1 mg or 0.4 mg of morphine in inguinal hernia repair surgeries. Anesthesia onset time (sensory and motor blocks) as well as postoperative recovery (first mobilisation, first voiding) time were compared. Also the postoperative pain management and side effects (nausea, vomiting and pruritus) were assessed.
