Abstract: Objective To investigate the effects of transverse abdominis plane(TAP) block on postoperative analgesia in old patients undergoing laparoscopic inguinal hernia repair. Methods Forty consecutive cases of old patients with laparoscopic inguinal hernia repair were randomly divided into observation group (group A) and control group (group B), 20 cases in each group. After general anesthesia induction, patients received ultrasound -guided TAP block, with 0.25% ropivacaine 1.5 mg/kg (group A) or saline(group B). Two groups of patients were given 40 mg parecoxib sodium and patient-controlled intravenous analgesia on postoperative. Observe the rest- visual analogue scales (VAS) score after surgery at 2 (T1), 6(T2), 12 (T3), 24 h (T4) data on the number of patients with nausea and vomiting were collected. Results The VAS score of group A were lower than group B at T1, T2 , T3 (P<0.05). VAS at T4 there were no significant different (P>0.05). The PCA pressing times of group A was (4.9±1.2), were less than group B(8.6±2.2)(P<0.05). Compared with group A, the rate of occurrence of symptoms such as dizziness, nausea, vomiting were 45%,40%,20%, were more in group B(P<0.05). Conclusions TAP block improved postoperative analgesia in old patients undergoing laparoscopic inguinal hernia repair, and also reduced the dose of opioid drugs and for that matter their side effects.
