This study compares the incidence of pruritus (itching) requiring treatment between two doses of intrathecal morphine (0.1 mg vs 0.2 mg) when used for spinal anesthesia during cesarean section. The study aims to determine if the lower dose (0.1 mg) can reduce pruritus incidence while maintaining adequate pain relief.
