Preoperative versus postoperative ultrasound-guided rectus sheath block for improving pain, sleep quality and cytokine levels in patients with open midline incisions undergoing transabdominal gynecological surgery: a randomized-controlled trial.

ABSTRACT:

Background

Nerve block is usually performed before surgery because it inhibits reflection of the skin incision and reduces the amount of intraoperative anesthetic used. We hypothesized that performing rectus sheath block (RSB) after surgery would result in a longer duration of the analgesic effects and have a subtle influence on sleep time after surgery but that it would not decrease the perioperative cytokine levels of patients undergoing gynecological surgery.

Methods

A randomized, double-blinded, controlled trial was conducted from October 2015 to June 2016. Seventy-seven patients undergoing elective transabdominal gynecological surgery were randomly assigned to the following two groups: a general anesthesia group who received 0.5% ropivacaine hydrochloride RSB preoperati
