    The study compared patient-controlled intravenous analgesia with and without background infusion in parturients post-cesarean delivery.

  • 2

    No significant differences were found in analgesia demands or pain scores between the background infusion and no background infusion groups.

  • 3

    The background infusion group had significantly higher opioid exposure measured in intravenous morphine equivalents postoperatively.

  • 4

    Multimodal analgesia included liposomal bupivacaine transversus abdominis plane block, epidural hydromorphone, and oral acetaminophen.

  • 5

    The addition of background infusion did not enhance analgesic efficacy and may not be necessary in multimodal analgesia regimens.
