Randomized Controlled Trial
A randomised trial of bilateral erector spinae plane block vs. no block for thoracolumbar decompressive spinal surgery.
Major spinal surgery causes significant postoperative pain. We tested the efficacy and safety of bilateral erector spinae block on quality of recovery and pain after thoracolumbar decompression. We randomly allocated 60 adults to standard care or erector spinae block. ⋯ Erector spinae block reduced mean (SD) area under the curve pain during the first 24 postoperative hours: at rest, from 78 (49) to 50 (39), p = 0.018; and on sitting, from 125 (51) to 91 (50), p = 0.009. The cumulative mean (SD) oxycodone consumption to 24 h was 27 (18) mg in the control group and 19 (26) mg after block, p = 0.20. In conclusion, erector spinae block improved recovery and reduced pain for 24 h after thoracolumbar decompression surgery.

Randomized Controlled Trial
Impact of the pericapsular nerve group (PENG) block on postoperative analgesia and functional recovery following total hip arthroplasty: a randomised, observer-masked, controlled trial.
The pericapsular nerve group (PENG) block is a novel regional anaesthesia technique that aims to provide hip analgesia with preservation of motor function, although evidence is currently lacking. In this single-centre, observer-masked, randomised controlled trial, patients undergoing total hip arthroplasty received pericapsular nerve group block or no block (control group). Primary outcome measure was maximum pain scores (0-10 numeric rating scale) measured in the first 48 h after surgery. ⋯ The maximum pain score of patients receiving the pericapsular nerve group block was significantly lower than in the control group at all time-points, with a median (IQR [range]) of 2.5 (2.0-3.7 [0-7]) vs. 5.5 (5.0-7.0 [2-8]) at 12 h; 3 (2.0-4.0 [0-7]) vs. 6 (5.0-6.0 [2-8]) at 24 h; and 2.0 (2.0-4.0 [0-5]) vs. 3.0 (2.0-4.7 [0-6]) at 48 h; all p < 0.001. Moreover, the pericapsular nerve group showed a significant reduction in opioid consumption, better range of hip motion and shorter time to ambulation. Although no significant difference in hospital length of stay was detected, our results suggest improved postoperative functional recovery following total hip arthroplasty in patients who received pericapsular nerve group block.

Randomized Controlled Trial
The Effect of Erector Spinae Plane Blockade on Prevention of Postherpetic Neuralgia in Elderly Patients: A Randomized Double-blind Placebo-controlled Trial.
Postherpetic neuralgia (PHN) is the most common chronic complication following the onset of herpes zoster (HZ). Both the incidence of HZ and the proportion of patients with HZ who develop PHN rise with age. Ultrasound-guided erector spinae plane blockade (ESPB) has been reported to relieve neuropathic pain and PHN in elderly patients, but no randomized controlled trials have been conducted regarding the effect of ESPB on elderly patients with HZ in the acute or subacute phases. ⋯ For elderly patients suffering acute or subacute HZ, ESPB reduces the incidence of PHN at 12 weeks after treatment; it also decreases the occurrence of neuropathic pain, sleep disturbance, and anxiety/depression.

Ultrasound-guided nerve blocks have revolutionized the way we provide regional anesthesia. By providing effective perioperative pain control, regional anesthesia reduces opioid consumption, decreases length of stay, and increases patient/parental satisfaction. ⋯ They include failure to confirm intended block site, failure to optimize ultrasound images and identify artifacts, failure to recognize when regional anesthesia is an acceptable option, failure to implement alternative imaging techniques when anatomy is challenging, and failure to recognize disease states with abnormal anatomy that may require alternative blocks. These issues are easily addressed if the pediatric regionalist is cognizant of the appropriate ways to mitigate them, and, as such, we review strategies to avoid them.

Randomized Controlled Trial
The effect of erector spinae plane block on postoperative analgesia and respiratory function in patients undergoing laparoscopic cholecystectomy: A double-blind randomized controlled trial.
Laparoscopic cholecystectomy (LC) causes moderate-to-severe postoperative pain. Postoperative pain is one of the leading contributors to respiratory dysfunction following surgery. This study investigated the effect of erector spinae plane (ESP) block on postoperative analgesia and respiratory function in patients undergoing LC. ⋯ Bilateral ESP blocks provides adequate analgesia, allowing for a lower opioid requirement and significant respiratory function improvement after LC; therefore, we concluded that ESP block could be added to the multimodal analgesia protocol in LC.
