Parturients showing for elective cesarean section will be randomized into 3 groups by a computer generated randomization list. Each randomization slip will be put in a sealed envelope until patient enrollment. Patients will be divided into Group C: control group, given intrathecal bupivacaine 12.5 mg. Group M25: intrathecal bupivacaine 12.5mg + morphine 25 microgram. Group M50: intrathecal bupivacaine 12.5mg + morphine 50 microgram.
This study is designed to see the effect of low dose intrathecal morphine on promting enhanced recovery after cesarean delivery with early ambulation and reduction of hospital stay.
