The objective of this study was to compare the effect of adding meperidine or sufentanil to hyperbaric bupivacaine in patients undergoing elective cesarean delivery (CD) under spinal anesthesia.

The primary outcome was the first analgesic request time, and secondary outcomes included an analgesic requirement in the first 24 h and intraoperative and postoperative side effects.

This was a randomized, double-blind clinical trial in which patients were allocated into two groups.

One group received preservative-free meperidine 12.5 mg (1 mL) in addition to 0.5% 10 mg (2 mL) of hyperbaric bupivacaine for spinal anesthesia. The other group received sufentanil 5 μg (1 mL) added to 0.5% 10 mg (2 mL) of hyperbaric bupivacaine.
