Randomized Controlled Trial
Ultrasound-guided retrolaminar block versus ilioinguinal nerve block for postoperative analgesia in children undergoing inguinal herniotomy: A randomized controlled trial.
Ultrasound-guided retrolaminar block (RLB) is a new, safe and technically easy nerve block. To our knowledge, no studies have evaluated its analgesic efficacy in pediatric patients. This study aimed to compare the postoperative analgesic efficacy of RLB and ilioinguinal nerve block (INB) in pediatric patients undergoing unilateral inguinal herniotomy. ⋯ Retrolaminar block is superior to ilioinguinal nerve block in providing postoperative analgesia in pediatric patients undergoing unilateral inguinal herniotomy.

Meta Analysis
Effect of prone versus supine position in COVID-19 patients: A systematic review and meta-analysis.
To review the effects of prone position and supine position on oxygenation parameters in patients with Coronavirus Disease 2019 (COVID-19). ⋯ Our meta-analysis demonstrated that prone position improved PaO₂/FiO₂ ratio with better SpO₂ than supine position in COVID-19 patients. Given the limited number of studies with small sample size and substantial heterogeneity of measured outcomes, further studies are warranted to standardize the regime of prone position to improve the certainty of evidence. PROSPERO Registration: CRD42021234050.

Randomized Controlled Trial
Application of a new serratus anterior plane block in modified radical mastectomy under ultrasound guidance: A prospective, randomized controlled trial.
Post-operative pain is a significant concern following modified radical mastectomy in breast cancer patients. The serratus anterior plane block has recently been described as an effective technique for post-operative analgesia of modified radical mastectomy. The purpose of this study was to evaluate the analgesic efficacy and safety of a new serratus anterior plane (SAP) block for post-operative pain of mastectomy. ⋯ SAP block significantly attenuated post-operative pain and decreased opioids consumption in breast cancer patients undergoing modified radical mastectomy.

Randomized Controlled Trial
Combination of real-time needle-tip pressure sensing and minimal intensity stimulation limits unintentional intraneural injection during an ultrasound-guided peripheral nerve block procedure: A randomized, parallel group, controlled trial.
Ultrasound guidance does not eliminate the risk of intraneural injection, which must be avoided during PNB. Combining ultrasound guidance (USG), nerve stimulation (NS), and injection pressure monitoring is advocated to prevent nerve injury during PNB. We hypothesized that combining patient-tailored dynamic NS and real-time pressure sensing (RTPS) could reduce the incidence of intraneural injection and nerve puncture during USG PNB compared with a traditional fixed thresholds (Control) procedure. ⋯ Under the conditions of the study, dynamic triple monitoring combining RTPS, NS and USG decreases intraneural injection and unintentional needle-nerve contact and puncture during a PNB procedure.
