Brief summary

Spinal block with intrathecal morphine is a popular anesthetic technique in cesarean delivery. This technique brings about good maternal and neonatal outcomes as well as provides good postoperative pain control. Systematic review showed intrathecal morphine produced long period of pain control up to 27 hours. However, some patients still experienced moderate to severe pain which defined as postoperative pain score \>,= 4. From our institute survey, there were more than 50 percents of patients undergoing cesarean delivery receiving spinal block with intrathecal morphine experienced moderate to severe pain in the first 24 hours. The aim of the study is to determine the actual incidence and associated factors of patients whom experienced moderate to severe pain after spinal anesthesia with intrathecal morphine 200 mcg in cesarean delivery.

Detailed description

Spinal block with intrathecal morphine is a popular anesthetic technique in cesarean delivery. This technique brings about good maternal and neonatal outcomes as well as provides good postoperative pain control. Systematic review showed intrathecal morphine produced long period of pain control up to 27 hours. However, some patients still experienced moderate to severe pain which defined as postoperative pain score \>,= 4. From our institute survey, there were more than 50 percents of patients undergoing cesarean delivery receiving spinal block with intrathecal morphine experienced moderate to severe pain in the first 24 hours. Failure in achieve adequate pain control results in poor maternal satisfaction, effect breast feeding and may lead to chronic wound pain. The aim of the study is to determine the actual incidence of patients whom experienced moderate to severe pain after spinal anesthesia with intrathecal morphine 200 mcg in cesarean delivery. Also, factors that may involved moderate to severe postoperative pain will be analyzed and reported.
