Comparison of posterior transversus abdominis plane block and erector spinae plane block for postoperative analgesia after caesarean section performed under spinal anesthesia: a prospective randomized trial.

Key Points

• To evaluate the effectiveness of two different analgesia techniques for postoperative pain relief after cesarean sections.
• Participants were randomized into two groups: TAPB and ESPB.
• Postoperative analgesia was assessed within the first 24 hours after surgery.
• Rescue analgesia requirements and onset of pain relief were recorded.
• Patients receiving ESPB required significantly less rescue analgesia within 24 hours.
• ESPB provided a faster onset of pain relief compared to TAPB.
• The duration of effective analgesia was longer in the ESPB group.
