Abstract:

Objective To investigate the effect of ultrasound-guided transverse abdominis muscle plane block combined with rectus abdominis muscle block and laryngeal mask general anesthesia on patients undergoing laparoscopic tension-free hernia repair surgery. Method 50 patients who underwent tension-free hernia repair surgery at Xuzhou Mining Group Second Hospital from October 2022 to June 2024 were selected and randomly divided into a control group and an observation group using a random number table, with 25 patients in each group. The control group received transverse abdominis muscle plane block combined with laryngeal mask anesthesia, while the observation group received ascending rectus abdominis muscle block on the basis of the control group, and the anesthesia effect was compared. Result The observation group had better instantaneous blood pressure at the beginning of surgery than the control group, and used less remifentanil during surgery. The visual analogue scale scores at all postoperative time points were lower than those in the control group, and the differences were significant (P ＜ 0.01). Conclusion Ultrasound guided transverse abdominis muscle plane block combined with rectus abdominis muscle block and laryngeal mask general anesthesia can achieve good analgesic effect.
