Randomized Controlled Trial Comparative StudySurgical Pleth Index And Analgesia Nociception Index for intraoperative analgesia in patients undergoing neurosurgical spinal procedures, a comparative randomized study.
The Surgical Plethysmographic Index (SPI) and the Analgesia Nociception Index (ANI) have been suggested for the non-invasive intraoperative monitoring of nociception/anti-nociception balance. We aimed to compare patterns of intraoperative use of opioids, postoperative cortisol levels and postoperative pain scores after intraoperative analgesia guided either by ANI, SPI or anesthesiologist's judgment. ⋯ Both ANI and SPI guidance significantly modified intraoperative opioid use, but no modification of postoperative cortisol levels and postoperative pain was observed.

Randomized Controlled Trial Comparative StudySensory assessment and block duration of transmuscular quadratus lumborum block at L2 versus L4 in volunteers: a randomized controlled trial.
The efficacy of an ultrasound guided transmuscular quadratus lumborum block (QLB) for perioperative analgesia of the upper and lower abdomen remain debatable. The purpose of this study was to compare the cutaneous sensory blocked area (CSBA) between QLB blocks performed at the L2 vs. L4 levels. ⋯ Ultrasound guided transmuscular QLB injection of 0.375% 20 mL ropivacaine at the L2 level produced a widespread cutaneous sensory blockade and a prolonged sensory block to cold sensation compared with the L4 level.
