Postoperative analgesic efficacy of intertransverse process block vs. erector spinae plane block in total laparoscopic hysterectomy: a randomized double-blind trial.
Intertransverse process block cut postoperative morphine-equivalent opioid use vs erector spinae plane block
Postoperative analgesic efficacy of intertransverse process block vs. erector spinae plane block in total laparoscopic hysterectomy: a randomized double-blind trial.
Due to multiple factors, patients will experience significant postoperative pain following laparoscopic total hysterectomy (total hysterectomy), predominantly manifesting as visceral pain.
We hypothesized that intertransverse process block would further reduce the perioperative opioid dosage and improve visceral pain in total hysterectomy patients when compared with erector spinae plane block.
Were assigned by randomization to either an intertransverse process block or erector spinae plane block group.
Intertransverse process block patients needed less morphine equivalent than erector spinae plane block patients after surgery
The intertransverse process block group also exhibited significantly lower Numerical Rating Scale (Numerical Rating Scale) scores for visceral pain upon awakening and at 2, 4, 6, 8, and 24 h after surgery when compared to the erector spinae plane block group ( p < 0.001).
Similarly, Numerical Rating Scale scores for incisional pain were significantly lower in the intertransverse process block group immediately after awakening and at 4, 6, and 8 h postoperatively ( p < 0.05).
Compared with erector spinae plane block, intertransverse process block more effectively reduced perioperative opioid consumption and provided superior and sustained postoperative visceral analgesia for patients undergoing total laparoscopic hysterectomy.
In addition, intertransverse process block was associated with improved short-term postoperative recovery quality.
In future, studies need to elucidate the underlying mechanisms of intertransverse process block and optimize the volume and concentration of local anesthesia for administration.
