Efficacy of combined ultrasound guided anterior and posterior rectus sheath block for postoperative analgesia following umbilical hernia repair: Randomized, controlled trial

Conclusion Addition of ultrasound anterior rectus sheath block together with posterior rectus sheath block added more significant analgesia than if we perform posterior rectus sheath alone. This was evidenced by decrease in Intraoperative rescue fentanyl, PACU morphine analgesia, 24h morphine and pain assessment score.
