Perioperative hypersensitivity reactions may be difficult to diagnose during general anesthesia. Postinduction hypotension is the most common sign but is not specific. It was recently suggested that low end-tidal carbon dioxide (ETco2) might be a marker of anaphylaxis (Ring and Messmer grades III to IV immediate hypersensitivity reactions) in hypotensive patients under mechanical ventilation. To test this hypothesis, the authors compared ETco2 in patients with a diagnosis of anaphylaxis and in patients with severe hypotension from any other cause after the induction of anesthesia. ⋯ In case of severe hypotension after anesthesia induction, a low ETco2 contributes to the diagnosis of anaphylaxis, in addition to the classical signs of perioperative immediate hypersensitivity.

A 27-year-old man with a history of bronchiolitis obliterans caused by a severe viral illness during early childhood that necessitated lung transplantation who was receiving tacrolimus therapy presented with rapidly worsening mental status. Prior to his change in mental status, his postoperative course was complicated by severe primary graft dysfunction and acute renal failure due to acute tubular necrosis that required continuous renal replacement therapy (CRRT). The patient had a prolonged intubation that required periodic BAL for mucous plugging. ⋯ After arousing that morning, the patient became combative, violent, and confused. This altered mentation progressed throughout the day to somnolence and lethargy, necessitating endotracheal intubation for airway protection. The patient experienced subsequent hypotension that necessitated low-dose epinephrine and vasopressin infusions.

Pro-Con Debate: Anesthesiologist- Versus Hospitalist- Run Preoperative Clinics and Perioperative Care.
In this Pro-Con commentary article, we discuss the models, value propositions, and opportunities of preoperative clinics run by anesthesiologists versus hospitalists and their role in perioperative care. The medical and anesthesia evaluation before surgery has pivoted from the model of "clearance" to the model of risk assessment, preparation, and optimization of medical and psychosocial risk factors. ⋯ There is ongoing debate regarding which model of preoperative assessment provides the most optimal preparation for the patient undergoing surgery. This article hopes to shed light on this debate with the data and perspectives on these care models.
