Analgesic effects of different patient-controlled intravenous analgesia infusion modes post cesarean section under multimodal analgesia: a retrospective cohort study
Comparative Analysis of Patient-Controlled Intravenous Analgesia Infusion Strategies Following Cesarean Delivery
Overview
This study investigates the analgesic efficacy of patient-controlled intravenous analgesia (PCIA) with and without background infusion in parturients receiving multimodal analgesia after cesarean delivery. The findings indicate that background infusion does not enhance analgesic efficacy and is associated with increased opioid consumption.
Background
Expand on the consequences of chronic pain and the necessity for effective pain management.

Key Findings
No significant difference in PCIA demands between groups at 0-24 h and 24-48 h.
Higher 48-h intravenous morphine equivalent doses were observed in the background infusion group.
Background infusion did not improve rest/ambulation pain scores compared to no background infusion.
Multimodal analgesia including liposomal bupivacaine TAP block was utilized in both groups.
Increased opioid exposure was noted with background infusion despite no enhanced analgesic effect.
Clinical Implications
Clinicians should consider avoiding background infusion in PCIA for parturients receiving multimodal analgesia after cesarean delivery, as it does not improve pain control and increases opioid consumption. This approach aligns with contemporary guidelines advocating for opioid-sparing strategies.
Conclusion
Reinforce the alignment with current clinical guidelines for postoperative care.
