U.S., Nov. 6 -- ClinicalTrials.gov registry received information related to the study (NCT07919340) titled 'Comparison of the Effectiveness of the Longitudinal Subcostal Versus Anterior Approach to Quadratus Lumborum Block for Post-Cesarean Analgesia' on Nov. 01.

Brief Summary: **Brief Summary**

This assessor-blinded randomized clinical trial compared the analgesic effectiveness of longitudinal subcostal (QL-LS) and anterior (QL-A) quadratus lumborum blocks following cesarean section. Both approaches provided comparable pain control at rest and during movement. The QL-LS group demonstrated a significantly longer time to first rescue analgesia than the QL-A group (419.5 vs. 295.5 minutes; p < 0.001), without a significant difference in 24-...
