Abstract
KUMAR REDDY, Nimmala Vinod; PRABHU, Manjunath; KANAKALAKSHMI, Sushma Thimmaiah and MUHAMED, Shiyad. Randomized comparison between transversus abdominis and erector spinae blocks in cesarean section. Rev. colomb. anestesiol. [online]. 2023, vol.51, n.3, 30. Epub Sep 02, 2023. ISSN 0120-3347. https://doi.org/10.5554/22562087.e1072.
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).
Conclusions:
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.
