Effects of Ropivacaine Combined with Ketorolac Transverse Abdominis Plane Block on Postoperative Analgesia in Patients Undergoing Gynecological Laparoscopic Surgery

Abstract
Objective — To observe the effects of ropivacaine combined with ketorolac transverse abdominis plane (TAP) block on postoperative analgesia in patients undergoing gynecological laparoscopic surgery. Methods — 90 ASAⅠorⅡpatients, aged 18-65 years and weighting 40-80 kg, scheduled for gynecological laparoscopic surgery were recruited and divided into three groups using random number table:ropivacaine combined with ketorolac 15 mg/side for TAP block (KR group), ropivacaine for TAP block and 30 mg preoperatively intravenous ketorolac (KIVR group) and ropivacaine for TAP block alone (R group) with 30 patients in each group. Intraoperative opioid consumption, Bruggrmann comfort scale (BCS) scores at 2h (T1), 4h (T2), 8h (T3), 12h (T4), 16h (T5), 24h (T6) after surgery were recorded. Adverse reactions such as nausea and vomiting, respiratory depression, local anesthetic poisoning, gastrointestinal bleeding, and complications related to TAP block operation were recorded. Results — The total consumpsion of sufentanil was higher in the R group than that in the KIVR group and KR group (P < 0.05). The total dosage of remifentanil in R group was higher than that in KR group (P < 0.05). The BCS scores of the three groups at T3, T4, T5 and T6 were lower in R group than that in KR group (P < 0.05) while R Group was lower than KIVR group at T3 and T4 (P < 0.05), and KIVR group was lower than KR group at T5 and T6. There was no statistically differences in BCS score between the three groups at T1 and T2 (P > 0.05). No statistical differences in the incidence of adverse reactions among all groups were observed. Conclusion — Ropivacaine combined with ketolorac transverse abdominisplane block reduced the intraoperative opioid consumption, improved postoperative comfort score and do not increased the incidence of adverse reactions in gynecological laparoscopic surgery.
