Objective To investigate the effects of different times of transversus abdominis plane block on postoperative pain in children undergoing laparoscopic surgery. Methods A total of 80 patients, ASA grade Ⅰ-Ⅱ, aged 2-7, scheduled for elective laparoscopic high ligation of pediatric hernia sac were recruited and randomly divided into preoperative group(group B, n=40) and postoperative group(group A, n=40). The two groups received bilateral transversus abdominis plane block before and after surgery respectively. The FLACC scores at 2, 4, 6, 12 and 24 h after surgery and the press times of self-control analgesia pump were recorded. The anesthesia time, operation time, postoperative extubation time and the highest PAED score during PACU stay were also compared between the two groups. The dosages of propofol and remifentanil, chills, vomiting, subcutaneous haematomas, urinary retention and other adverse reactions were also recorded. Results Compared with group A, the FLACC scores were significantly decreased at 2, 4 and 6 h after surgery(P0.05). The press times of self-control analgesia pump and the dosages of remifentanil were significantly decreased in group B than in group A(P0.05). There were no significant differences in the anesthesia time, operation time, postoperative extubation time, the highest PAED score during PACU stay and the incidence adverse reactions between the two groups(P0.05). Conclusion Preoperative transversus abdominis plane block can significantly reduce postoperative pain in children undergoing laparoscopic surgery and reduce the use of analgesics during surgery compared with postoperative transversus abdominis plane block, with good clinical safety.
