Ultrasound guided tap block: Comparison of analgesic efficacy of levobupivacaine and ropivacaine

Journal Title: Medpulse International Journal of Anesthesiology - Year 2019, Vol 10, Issue 2

Abstract

Study objective: Ultrasound guided transverse abdominis plane (TAP) block is an effective method of providing postoperative analgesia in patients undergoing abdominal surgeries. We compared the postoperative analgesic efficacy of 0.5% levobupivacaine and 0.5% ropivacaine and post-operative hemodynamic variables after total abdominal hysterectomy (TAH) performed through a Pfannenstiel incision. Design: A prospective randomized double blinded study. Setting: Operating room of Navodaya Medical College Hospital and Research Centre, Raichur. Patients: Seventy female patients aged 45-60 years, of ASA-PS I or II, scheduled for elective TAH under general anesthesia, were recruited in this study. Interventions: Patients were randomized into 2 groups (Group L-0.5% levobupivacaine, Group R- 0.5%ropivacaine). At the end of surgery, bilateral TAP block given under ultrasound guidance. Measurements: Duration of postoperative analgesia, time for requirement of first rescue analgesic, VAS score and postoperative hemodynamic variables were assessed for 48hours postoperatively. Statistical analysis was done using SPSS 18.0, and R environment ver.3.2.2. ANOVA/Chi-square/ Fisher Exact test to assess significance of the study. Results: Patients in Group R had longer duration of postoperative analgesia, 15.33±0.40 hours than Group L, 14.16±0.24 hours. Postoperative VAS score hours (p<0.001) was lower up to 14hours in group-L compared to 16 hours in group-R. 65.7%patients required rescue analgesic at 14th hour in group L whereas; in group R were 80% patients required first dose of rescue analgesic at 16th hour. Hemodynamic parameters were comparable in both the groups. Conclusion: 0.5% ropivacaine in ultrasound guided TAP block provides longer duration of post-operative analgesia, delays the requirement of first dose of rescue analgesic. Whereas, its hemodynamic stability is comparable with 0.5% levobupivacaine.
