Effects of transversus abdominis and erector spinae plane blocks on postoperative pain control and postpartum depression after cesarean section: a randomized prospective study

With the ESP block, no significant difference was observed compared to the TAP block in terms of total analgesic duration, opioid consumption, postpartum depression, or patient satisfaction, except for the postoperative 1-h VAS pain score. This suggests that the ESP block does not provide clear superiority over the TAP block.
