Comparative study of analgesic effect of simple lidocaine and ropivacaine-plus in inguinal hernia tension-free repair in adults / 中华普通外科杂志

ABSTRACT

Objective To investigate the analgesic effect of lidocaine plus ropivacaine in inguinal hernia tension-free repair under local anesthesia.Methods A total of 815 patients with unilateral inguinal hernia admitted to Chaoyang Hospital from July 2013 to Jane 2014 were enrolled in this retrospective study.The patients were divided into 2 groupslocal anesthesia using a combination of 1％ lidocaine (l0 ml) and 0.75％ ropivacaine (10 ml) in observation group (n =412),and 1％ lidocaine (20 ml) were administered in control group (n =403).Postoperatively heart rate (HR),mean arterial pressure (MAP),pain intensity (VAS),analgesic demand,adverse events and hospital duration were assessed.Results There was no significant difference between the 2 groups in postoperative hemodynamic monitoring (all P ＞ 0.05).VAS score in observation group were lower than those in control group at 1,3,6 and 9 h.The former needed significantly less pain killer (all P ＜ 0.05).Conclusion Ropivacaine decreases postoperative pain level after tension-free inguinal hernia repair without additional risk of perioperative events.
