Randomized comparison between transversus abdominis and erector spinae blocks in cesarean section

Keywords: Analgesia, Cesarean section, Erector spinae block, Regional anesthesia, Transversus abdominis block, Anesthesia


Introduction: Transversus abdominis plane (TAP) block provides somatic analgesia postoperatively in cesarean sections, however erector spinae plane (ESP) block has shown to provide both somatic and visceral analgesia.

Objective: To compare the efficacy of TAP and ESP blocks for pain control after cesarean section under spinal anesthesia.

Methods: In a double-blind superiority trial, pregnant patients undergoing cesarean section were randomized into either bilateral TAP or ESP block groups. Primary outcome was total consumption of patient-controlled analgesia (PCA) tramadol in the first 24 hours. Secondary outcomes included time required for first rescue analgesia, post-surgery visual analog score (VAS) for pain, patient satisfaction, and adverse effects.

Results: 50 pregnant patients were randomized into TAP and ESP blocks. There was no difference in the amount of PCA tramadol within the first 24 hours between both groups [100mg (63,125) in TAP group vs 75mg (38,100) ESP group]. Pain score at rest and on movement and patient satisfaction were comparable in both groups, with no difference in adverse effects. There was a slight difference in the median time for first rescue analgesia [210min (135,315) in TAP group and 270min (225,405) ESP group] (p=0.03).

Conclusion: TAP and ESP blocks provide similar analgesia with comparable consumption of tramadol in the first 24 hours post-cesarean section and no difference in pain scores at rest/on movement.
