Randomized Controlled TrialUltrasound-guided transverse abdominis plane block, ilioinguinal/iliohypogastric nerve block, and quadratus lumborum block for elective open inguinal hernia repair in children: a randomized controlled trial.
Ultrasound-guided ilioinguinal/iliohypogastric (II/IH) nerve blocks and transverse abdominis plane (TAP) blocks are widely used for postoperative analgesia in children undergoing inguinal hernia repair (IHR). Quadratus lumborum block (QLB) provides analgesia for both upper and lower abdominal surgery. Very few randomized controlled trials in children have assessed the efficacy of QLB in IHR. Thus, this study was designed to find the comparative effectiveness of QLB versus TAP and II/IH blocks in children undergoing open IHR. ⋯ QLB provides a prolonged period of analgesia and leads to decreased opioid consumption compared with TAP blocks and II/IH nerve blocks in children undergoing open IHR.

Randomized Controlled TrialDepth of cervical plexus block and phrenic nerve blockade: a randomized trial.
Cervical plexus blocks are commonly used to facilitate carotid endarterectomy (CEA) in the awake patient. These blocks can be divided into superficial, intermediate, and deep blocks by their relation to the fasciae of the neck. We hypothesized that the depth of block would have a significant impact on phrenic nerve blockade and consequently hemi-diaphragmatic motion. ⋯ We studied the characteristics and side effects of cervical plexus blocks by depth of injection. Diaphragmatic dysfunction was most pronounced in the deep cervical plexus block group.

Randomized Controlled TrialED90 of spinal 2-chloroprocaine 1% in ambulatory knee arthroscopy up to 45 min: a randomized biased-coin- up-and-down sequential allocation trial.
A short acting spinal anesthetic facilitates smooth flow since quick recovery of motor function will facilitate unassisted ambulation. The aim of this study was to estimate the effective dose (ED90) of intrathecal 2-chloroprocaine 1% in outpatient knee arthroscopy. ⋯ The ED90 of 2-chloroprocaine 1% in knee arthroscopy was estimated to be 27.8 mg. In an external population, the ED90 resulted in successful anesthesia in 98% of the patients (95% CI 89% to 100%).
