Objective:

To examine the clinical efficacy of the rectus sheath block (RSB) in managing perioperative pain during midline laparotomies and compare it to alternative anaesthetic methods, such as neuraxial blocks and systemic opioids.

Key Findings:
  • RSB provides effective analgesia for midline abdominal incisions, reducing reliance on systemic opioids and enhancing overall pain management.
  • The technique is enhanced by ultrasound guidance, improving safety and reliability.
  • RSB targets somatic pain, necessitating multimodal analgesia for comprehensive visceral pain management.
Interpretation:

The RSB is a valuable addition to multimodal analgesic strategies in ERAS protocols, offering targeted pain relief with fewer systemic side effects.

Limitations:
  • Complications from RSB, while uncommon, can occur, particularly from inadvertent vascular puncture, leading to hematoma or other issues.
  • Further research is needed to optimize techniques and assess long-term outcomes.
Conclusion:

The rectus sheath block is an effective, opioid-sparing technique for managing postoperative pain in midline laparotomy, aligning with contemporary ERAS principles and enhancing recovery.
