Evaluation of ultrasound-guided transversalis fascia plane block for postoperative analgesia in cesarean section: A prospective, randomized, controlled clinical trial
MetadataShow full item record
Study objective: Cesarean Delivery (CD) is a commonly performed obstetric procedure. Adding a regional anesthesia technique to multimodal analgesia in CD, may improve the quality of postoperative analgesia. In this study we evaluated the efficacy of Transversalis Fascia Plane Block (TFPB) for postoperative analgesia management in CD. Design: Blinded, prospective, randomized study. Setting: Postoperative recovery room & ward, tertiary university hospital, Istanbul, Turkey, Patients: Seventy-five patients (ASA II-III) scheduled to undergo Cesarean delivery were recruited. Following exclusion, 70 patients were randomized into two equal groups (block and control group). Interventions: Standard multimodal analgesia (routine paracetamol and tramadol PCA in addition to diclophenac sodium as rescue analgesia) was performed in Group C while TFPB block was also performed in the intervention (TFPB) group. Measurements: The primary outcome was tramadol consumption within the first 24 h. The secondary outcome was Numeric Rating Scale (NRS) scores during rest and movement/coughing. Main results: Tramadol consumption in the first 24 h was 175 ± 72.32 mg in the control and 101.42 ± 51.45 mg in the TFPB group (p < 0.05). NRS was lower in Group TFPB during the first 3 h and at the 12th hour. There was no difference in NRS scores at other hours. Conclusion: Bilateral ultrasound guided TFPB leads to effective analgesia and a decrease in analgesia requirement in first 24 h in patients undergoing CD. © 2019 Elsevier Inc.
