Objectives

Narrative objectives1

Pain at the laparoscopic port insertion site is a postoperative complaint in patients undergoing laparoscopic inguinal hernia repair. Although opioid-based analgesia is extremely effective, it is associated with postoperative side effects such as nausea and vomiting. Multimodal analgesia has recently become well-established because it reduces opioid use by combining non-opioid analgesics with a peripheral nerve block. Rectus sheath block (RSB) and transverse abdominis plane block are effective peripheral nerve blocks for laparoscopic surgery. RSB is simple to perform when surgical incisions are localized to the abdominal midline. Local anesthetic is injected into the space between the rectus abdominis muscle and the posterior layer of the rectus sheath, and spread lenticularly within this space. However, a potential complication of RSB is an internal injury due to peritoneal puncture. Injecting the local anesthetic into the rectus abdominis muscle produces an analgesic effect, reduces the likelihood of peritoneal puncture, and improves the safety of the procedure. We present a comparison of the analgesic effect achieved using the conventional RSB method with injection into the rectus sheath (hereinafter, original method), and the intramuscular RSB method involving injection into the rectus abdominis muscle (intramuscular method).
