It is unclear what the body mass index (BMI) should be when performing surgery involving the airway at an outpatient surgery facility. The objective of this study was to evaluate the association of Class 3 obesity versus a composite cohort of Class 1 and 2 obesity with same-day hospital admission following outpatient tonsillectomy in adults. ⋯ These results contribute data that may help practices - especially freestanding ambulatory surgery centers - decide appropriate BMI cutoffs for surgery involving the airway. Whether this is considered clinically significant enough to rule out eligibility will differ from practice-to-practice and will depend on surgical volume, resources available and financial interests.

Observational Study
The impact of invasive respiratory support on the development of postoperative atrial fibrillation following cardiac surgery.
Postoperative atrial fibrillation (POAF) is a frequent complication after cardiac valve- or coronary artery bypass (CABG) surgery and is associated with increased mortality. While it is known that prolonged postoperative invasive ventilation triggers POAF, the impact of ventilatory settings on POAF development has not been studied yet. ⋯ The ventilatory settings of plateau pressure, driving pressure, and respiration rate after cardiac surgery influence POAF occurrence probability. Optimized postoperative care such as lung-protective ventilation and increased awareness towards postoperative ventilatory efforts should be considered to prevent POAF development and poor patient outcome.
