| Sumario: | Objective The aim of this study was to evaluate and compare the postoperative analgesic efficacy of intrathecal buprenorphine with ultrasonography (USG)-guided transversus abdominis plane (TAP) block in patients of cesarean section.
Materials and Methods: Sixty American Society of Anesthesiologists grade I and II pregnant women aged between 20 and 40 years requiring lower segment cesarean section were included in this study.
Study Design A prospective randomized comparative study.
Study Groups Group A received intrathecal hyperbaric bupivacaine 0.5% 1.8 mL with 60 µg buprenorphine. Group B received intrathecal hyperbaric bupivacaine 0.5% 1.8 mL with 0.2 mL sterile normal saline and at the end of surgery USG-guided bilateral TAP block was given with 20 mL 0.25% bupivacaine on each side of abdomen.
Results The mean ± standard deviation of time to first rescue analgesia in Group A and group B was 9.17 ± 0.64 hours and 5.59 ± 0.50 hours, respectively. Distribution of mean time to first rescue analgesia among the cases studied is significantly higher in group A compared with group B. The distribution of paracetamol and tramadol requirement in first 24 hours among the cases studied was significantly higher in group B compared with group A.
Conclusion The addition of buprenorphine to intrathecal hyperbaric bupivacaine has advantages over USG-guided TAP block for postoperative analgesia after cesarean section—longer duration of postoperative analgesia, lower analgesic requirements over first 24 hours, and cost–effectiveness. |
