The number of caesarean deliveries has been increasing. Although intrathecal morphine (ITM) can relieve pain and is widely applied in caesarean deliveries, it is associated with many side effects.

This study mainly compares the analgesic and adverse effects of ITM and TAPB in caesarean delivery. |
