Intraoperative factors associated with unplanned return to the operating room after emergent hemorrhage control surgery.

Background: Unplanned return to the operating room (uROR) is associated with worse outcomes and increased mortality. Little is known regarding intraoperative factors associated with uROR after emergent surgery in trauma patients. The objective of this study was to identify intraoperative factors associated with uROR after emergent hemorrhage control procedures in bleeding trauma patients.

Impact of Outpatient Antihypertensive Medication Use on Epinephrine Resistance in Anaphylaxis.

Background: There has been an increase in allergy-related emergency department (ED) visits over the past several years. Underlying cardiovascular disease or respiratory disease and concurrent beta blocker or angiotensin-converting enzyme inhibitor use have been identified as potential risk factors for severe or refractory anaphylactic reactions. Conflicting evidence exists regarding the association between antihypertensive (AH) use and the incidence of refractory anaphylaxis.
