About this trial
Study Design This retrospective observational study aims to evaluate and compare the effects of two regional anesthesia techniques, Erector Spinae Plane (ESP) block and Retrolaminar Block (RLB), on postoperative recovery quality in women undergoing elective cesarean section (CS). Postoperative pain after CS is common, particularly in the first 24-72 hours, and can affect mobility, breastfeeding, and overall well-being. Effective pain management is therefore critical for both patient comfort and maternal-infant bonding.
Participants and Methods Medical records of adult women aged 18-45 years, with a singleton pregnancy at ≥37 weeks, who underwent elective CS under spinal anesthesia in our clinic, were retrospectively reviewed. Patients who had received either ESP or RLB immediately after surgery were included. Both blocks had been performed under ultrasound guidance at the T9 level using 20 mL of 0.25% bupivacaine, according to institutional practice. Standard perioperative care and analgesia protocols were applied to all patients.
Outcomes The primary outcome was postoperative recovery quality, assessed 24 hours after surgery using the Turkish version of the Obstetric Quality-of-Recovery Score (ObsQoR-11T), a validated tool addressing physical, emotional, and functional aspects of recovery. Secondary outcomes included postoperative pain intensity (Visual Analog Scale), opioid consumption, adverse events, and patient satisfaction, as documented in patient files.
Conclusion This retrospective study will provide evidence on which block technique more effectively improves recovery quality after CS and may help optimize postoperative analgesia strategies in Turkish obstetric populations.
