Antibiotics play a crucial role in preventing surgical site infections, yet adherence to Infectious Disease Society of America guidelines varies widely. This qualitative study aimed to explore factors influencing perioperative antibiotic administration and assess the potential impact of a clinical decision support tool on guideline adherence. ⋯ Nonadherence to antibiotic guidelines in the perioperative setting often results from a lack of structured workflow. The 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.

Randomized Controlled Trial Multicenter Study
Chewing gum to treat postoperative nausea and vomiting in female patients: a multicenter randomized trial.
Postoperative nausea and vomiting is common after general anesthesia, with consequences for patient outcomes, satisfaction with care, and healthcare costs. The aim was to compare a new treatment, chewing gum, with a widely used intravenous agent, ondansetron, to treat postoperative nausea and vomiting in female patients in the postanesthesia care unit. ⋯ Chewing gum cannot be recommended as an alternative to ondansetron for treatment of postoperative nausea and vomiting in female patients administered antiemetic prophylaxis.

Multicenter Study
Covert perioperative strokes in older patients having non-cardiac surgery (PRECISION): a prospective cohort analysis.
Perioperative strokes may promote postoperative neurocognitive dysfunction. This study thus evaluated the incidence of postoperative strokes and the association between strokes and postoperative neurocognitive outcomes in older patients recovering from noncardiac surgery. ⋯ Among patients aged 60 yr and older who had major noncardiac surgery, mainly intracranial, one in nine patients experienced a perioperative covert stroke. Covert strokes more than doubled the risk of postoperative delirium and long-term neurocognitive decline. Covert perioperative strokes are common and clinically meaningful.

Effects of Sub-Anesthetic Oro-Mucosal Dexmedetomidine on Sleep in Humans: A Randomized, Controlled Pharmacokinetics-Pharmacodynamics Study.
The locus coeruleus noradrenergic system may provide a potential new target for pharmacologic insomnia treatment, particularly in patients suffering from elevated distress. The selective α 2 -noradrenergic agonist dexmedetomidine attenuates locus coeruleus activity in subanesthetic doses, yet no adequate nonparental delivery systems of dexmedetomidine are currently available. To examine the feasibility of oromucosal dexmedetomidine administration, the authors developed two distinct-one sublingual and one buccal-oromucosal, fast-disintegrating dexmedetomidine formulas tailored for self-administration. Here, the authors established the formulas' pharmacokinetic and pharmacodynamic profiles. ⋯ The favorable pharmacokinetic and pharmacodynamic profile of oromucosal dexmedetomidine delivery warrants further dose-finding and clinical studies to establish the exact roles of α 2 receptor agonism in pharmacologic sleep enhancement and as a possible novel mechanism to alleviate stress-related insomnia.
