Randomized Controlled Trial
Anterior quadratus lumborum block at the lateral supra-arcuate ligament versus transmuscular quadratus lumborum block for postoperative analgesia in patients undergoing laparoscopic nephrectomy: A randomized controlled trial.
The analgesic efficacy of transmuscular quadratus lumborum block (TQLB) to decrease the need for opioid consumption after laparoscopic nephrectomy has been demonstrated in several studies. However, the effect of an anterior QLB approach at the lateral supra-arcuate ligament (QLB-LSAL) in this surgical context is unclear. Here, we aimed to compare postoperative analgesic effects of the two block approaches in laparoscopic nephrectomy. ⋯ The results indicate that, compared to TQLB, QLB-LSAL is a beneficial nerve block that can reduce postoperative opioid consumption, making it a potentially superior approach to achieve multimodal analgesia after laparoscopic nephrectomy.

A lateral mini-thoracotomy approach to cardiac surgery causes severe and complicated postoperative pain compared to the sternotomy approach. In this study we assessed the benefits and risks of intermittent bolus erector spinae plane block (ESPB) via a catheter for patients who underwent cardiac surgery through a lateral mini-thoracotomy. ⋯ Intermittent bolus ESPB is relatively safe and correlated with a reduction in the use of opioids and antiemetics for cardiac surgery through a lateral mini-thoracotomy.
