Socioeconomic, Patient, and Hospital Determinants for the Utilization of Peripheral Nerve Blocks in Total Joint Arthroplasty.
While peripheral nerve blocks (PNBs) are associated with various improved outcomes in patients undergoing total hip or knee arthroplasty (THA/TKA), disparities in PNB utilization have been reported. This study assessed the importance of socioeconomic, demographic, clinical, and hospital determinants in explaining PNB utilization using the population-attributable risk (PAR) framework. Subsequently, we examined the association between PNB use and 3 secondary outcomes: Centers for Medicare and Medicaid Services (CMS)-defined complications, 90-day all-cause readmissions, and length of stay >3 days. ⋯ Among THA and TKA patients on Medicare, large variations exist in the utilization of PNBs by clinical and hospital variables, while demographic and socioeconomic variables played a limited role. Given the consistent benefits of PNBs, particularly in TKA patients, more standardized provision may be warranted to mitigate the observed variation.

Data on the effectiveness of erector spinae plane block (ESPB) for patients undergoing liver surgeries is limited and inconclusive. We hereby aimed to systematically review if ESPB can provide adequate analgesia after liver surgery. ⋯ ESPB may not provide any significant postoperative analgesia in liver surgery patients. There was a tendency of reduced opioid consumption with ESPB. Limited data also showed that ESPB and spinal analgesia had no difference in pain scores and 24-hour analgesic consumption.

Randomized Controlled Trial
Ultrasound-guided lesser occipital nerve combined with great auricular nerve block for vestibular schwannoma craniotomy via a suboccipital retrosigmoid approach: a prospective, double-blind randomized controlled trial.
This aim of this study was to investigate the analgesic efficacy and safety of lesser occipital nerve combined with great auricular nerve block (LOGAB) for craniotomy via a suboccipital retrosigmoid approach. ⋯ Chictr.org.cn ChiCTR2000038798.

Effects of popliteal plexus block after total knee arthroplasty: a randomized clinical trial.
Motor-sparing peripheral nerve blocks enhance multimodal opioid-sparing strategies after total knee arthroplasty. We hypothesized that adding a popliteal plexus block to a femoral triangle block could reduce 24-hour opioid consumption after total knee arthroplasty, compared with standalone femoral triangle block or adductor canal block. ⋯ Adding a popliteal plexus block to a femoral triangle block resulted in a statistically significant reduction of 24-hour postoperative opioid consumption after total knee arthroplasty. However, no differences were found in pain scores. Popliteal plexus block did not impair the lower leg muscles.

Acute reversal of respiratory distress after a preoperative single-shot interscalene nerve block.
Diaphragmatic paresis is a known complication of the interscalene block used for postoperative analgesia in shoulder surgery. A technique involving the injection of normal saline through the interscalene catheter to alleviate this condition has shown promise. This method, termed the "washing-off" technique, dilutes the local anesthetic around the phrenic nerve, mitigating respiratory symptoms. ⋯ The "washing-off" technique's mechanism may involve dilutional effects, pH changes or local sodium concentration alterations affecting the phrenic nerve. This case demonstrates its effectiveness in an acute setting, enabling surgery under regional anesthesia without intubation or any additional analgesia. The previously considered placebo effect appears unlikely here.
