QLB vs. Wound Infiltration in Cesarean Section

Summary

Effective postoperative analgesia after cesarean section (CS) is important because it enables early ambulation and facilitates breast-feeding. A 2009 Cochrane review concluded that wound infiltration with local analgesic after CS reduced opioid consumption. In addition, two regional anesthetic techniques, the transversus abdominis plane (TAP) block and the quadratus lumborum block (QLB), have been shown in multiple studies to reduce post-operative opioid consumption after CS. A recent randomized controlled trial showed that QLB is more effective in reducing morphine consumption post-CS compared to TAP. No randomized controlled trial to date, however, compared the analgesic effect of QLB with infiltration of the wound after CS. The objective of the study is to compare the analgesic effect of QLB type 2 with wound infiltration after CS.
