We report a novel block technique aimed to provide lumbosacral, abdominal, and hip analgesia: The quadro-iliac plane (QIP) block. ⋯ The local anesthetic applied from a place where the QLM reaches its largest volume and the fascial plane creates a closed gap in the caudal area may exhibit a more rounded and extensive spread.Quadro-iliac plane block, involves the administration of local anesthetic to the posterior aspect of the QLM at its origin from the iliac crest. According to our cadaver study, this technique may be a promising option for alleviating acute and chronic pain in the lumbosacral, lower abdominal, and hip regions.

Randomized Controlled Trial
Craniocaudal spread and clinical translation for combined erector spinae plane block and retrolaminar block in soft embalmed cadavers: a randomised controlled equivalence study.
Erector spinae plane (ESP) block spread can be unpredictable. We previously improved the spread of ESP injection by addition of retrolaminar (RL) injection. However, it is not clear whether spread at high thoracic levels is similar to spread at midthoracic levels. Our primary objective was to demonstrate that craniocaudal dye spread was equivalent after combined ESP and RL injection using a 19 G Tuohy needle at the third (T3) and sixth (T6) vertebrae in soft embalmed Thiel cadavers. ⋯ Combined ESP and RL injections showed equivalent and consistent spread at T3 and T6 injection sites. A pilot study confirmed translation to patients.

Effect of Neurostimulator Usage on Block Success in Costoclavicular Block: A Randomized Controlled Trial.
The need of a neurostimulator for a successful nerve block was questioned in different block types after ultrasound had become standard. ⋯ Neurostimulator use did not affect block success in the CCB. Neurostimulator utilization prolonged block application time explicitly and did not change the complication rate. Ultrasound and injection pressure manometer are sufficient for a safe and successful CCB.

A thoracic paravertebral block can be a useful opioid-sparing technique for controlling postoperative pain after thoracic and visceral abdominal surgery. ⋯ Paravertebral block via the thoracic intervertebral foramen achieved consistent dye spread into the thoracic paravertebral space and epidural space, capturing retropleural organs.
