With estimated global post-operative mortality rates at 1-4% leading to approximately 3-12 million deaths per year, an urgent need exists for reliable measures of perioperative risk. Existing approaches suffer from poor performance, place a high burden on clinicians to gather data, or do not incorporate intraoperative data. Prior work demonstrated that intraoperative anesthetics induce prefrontal EEG oscillations in the alpha band (8-12Hz) that correlate with post-operative cognitive outcomes. ⋯ Intraoperative EEG alpha power is independently associated with post-operative mortality and adverse outcomes, suggesting it could represent a broad measure of post-operative physical resilience and provide clinicians with a low-burden, personalized measure of post-operative risk.

The locus coeruleus (LC) noradrenergic system may provide a potential new target for pharmacological insomnia treatment, particularly in patients suffering from elevated distress. The selective α2 noradrenergic agonist dexmedetomidine attenuates LC activity in sub-anesthetic doses, yet no adequate non-parental delivery systems of dexmedetomidine are currently available. To examine the feasibility of oro-mucosal dexmedetomidine administration, we developed two distinct - one sublingual and one buccal - oro-mucosal, fast-disintegrating dexmedetomidine formulas tailored for self-administration. Here we established their pharmacokinetic and pharmacodynamic (PK-PD) profiles. ⋯ The favorable PK-PD profile of oro-mucosal dexmedetomidine delivery warrants further dose-finding and clinical studies, to establish the exact roles of α2 receptor agonism in pharmacological sleep enhancement and as possible novel mechanism to alleviate stress-related insomnia.

Extracorporeal cardiopulmonary resuscitation (ECPR) for refractory in-hospital cardiac arrest has been associated with improved survival compared with conventional cardiopulmonary resuscitation (CPR). Perioperative patients represent a unique of the inpatient population. This study aims to describe and analyze the characteristics and outcomes of patients who received ECPR for perioperative cardiac arrest (POCA). ⋯ The use of ECPR for adults with POCA can be associated with excellent survival with neurologically favorable outcomes in carefully selected patients. Longer CPR time, higher lactate levels, and lower pH were associated with increased mortality. Given the small sample size, no other prognostic factors were identified, though certain trends were detected between survival groups.

Antibiotics play a crucial role in preventing surgical site infections, yet adherence to Infectious Disease Society of America (IDSA) guidelines varies widely. This qualitative study aimed to explore factors influencing perioperative antibiotic administration and assess the potential impact of a clinical decision support (CDS) tool on guideline adherence. ⋯ Non-adherence to antibiotic guidelines in the perioperative setting often results from a lack of structured workflow. Our interviews provide a foundation for developing a clinical decision support tool tailored to provider needs, aiming to improve user satisfaction and promote better adherence to perioperative antibiotic guidelines.
