A brachial plexus block plays an important role in providing perioperative analgesia for shoulder surgery; however, the inherent risk of phrenic nerve block and resulting hemidiaphragmatic paralysis may limit its use in patients with compromised pulmonary function. This study aimed to evaluate the safety, efficacy, maximum tolerated volume, and optimal biologic volume of 0.5% ropivacaine used in a single-injection retroclavicular brachial plexus block for arthroscopic shoulder surgery. ⋯ A single-injection retroclavicular brachial plexus block using 25 ml of 0.5% ropivacaine produced consistent block success with a minimal hemidiaphragmatic paralysis rate, suggesting the need for further studies to confirm this result in arthroscopic shoulder surgery.

Multicenter StudyIdentifying Variation in Intraoperative Management of Brain-Dead Organ Donors and Opportunities for Improvement: A Multicenter Perioperative Outcomes Group Analysis.
Intraoperative events and clinical management of deceased organ donors after brain death are poorly characterized and may consequently vary between hospitals and organ procurement organization (OPO) regions. In a multicenter cohort, we sought to estimate the incidence of hypotension and anesthetic and nonanesthetic medication use during organ recovery procedures. ⋯ Despite guidelines recommending maintenance of MAP >60 mm Hg in adult brain-dead organ donors, hypotension during recovery procedures was common. Future research is needed to clarify the relationship between intraoperative events with donation and transplantation outcomes and to identify best practices for the anesthetic management of brain-dead donors in the operating room.

Differences in Acute Postoperative Opioid Use by English Proficiency, Race, and Ethnicity After Total Knee and Hip Arthroplasty.
There is increasing interest in documenting disparities in pain management for racial and ethnic minorities and patients with language barriers. Previous studies have found differential prescription patterns of opioids for racial and ethnic minority group and patients having limited English proficiency (LEP) after arthroplasty. However, there is a knowledge gap regarding how the intersection of these sociodemographic factors is associated with immediate postoperative pain management. This study aimed to explore language and racial-ethnic disparities in short-term opioid utilization after total hip and knee arthroplasty. ⋯ We identified an association between LEP, racial-ethnic identity, and short-term postoperative OME utilization after total knee and hip arthroplasty. The observed differences in opioid utilization imply there may be language and racial-ethnic disparities in acute pain management and perioperative care.

Meta Analysis Comparative Study
High PEEP with recruitment maneuvers versus Low PEEP During General Anesthesia for Surgery - a Bayesian individual patient data meta-analysis of three randomized clinical trials.
The influence of high positive end-expiratory pressure (PEEP) with recruitment maneuvers on the occurrence of postoperative pulmonary complications after surgery is still not definitively established. Bayesian analysis can help to gain further insights from the available data and provide a probabilistic framework that is easier to interpret. The objective was to estimate the posterior probability that the use of high PEEP with recruitment maneuvers is associated with reduced postoperative pulmonary complications in patients with intermediate-to-high risk under neutral, pessimistic, and optimistic expectations regarding the treatment effect. ⋯ High PEEP with recruitment maneuvers demonstrated a moderate reduction in the probability of postoperative pulmonary complication occurrence, with a high posterior probability of benefit observed consistently across various prior beliefs, particularly among patients who underwent laparoscopy.
