Case Reports
A 44-Year-Old Woman with Dyspnea and Hemoptysis in the Setting of Remote Bariatric Surgery.
A 44-year-old woman was transferred to the ED from an outside hospital because of hemoptysis and concern for left-sided pulmonary infiltrate with associated pleural effusion. The patient presented to this outside hospital multiple times over the past 3 months because of left-sided shoulder pain, diffuse myalgias, and supraventricular tachycardia. On her third visit, she was found to have a left-sided pleural effusion and underwent diagnostic and therapeutic thoracentesis; 1.5 L of fluid was removed. ⋯ Before her transfer, the patient experienced foul-smelling, maroon-colored hemoptysis as well as anemia that required a higher level of care. On arrival to the ED, she was in acute hypoxic respiratory failure. The patient was intubated emergently and was admitted to the medical critical care unit for further treatment.

A 62-year-old White man with a history of orthotopic liver transplantation 16 years ago for alcoholic liver cirrhosis on chronic immunosuppression and recurrent decompensated cirrhosis of his graft liver complicated by ascites, hepatic encephalopathy, and esophageal varices presented to the hospital with altered mental status. Over the last few weeks, he had reduced frequency of bowel movements and subsequently developed altered sensorium 3 days before presentation. On arrival to the hospital, he was disoriented and had asterixis consistent with hepatic encephalopathy. ⋯ He subsequently underwent a bronchoscopy with BAL and transbronchial biopsy. BAL fluid was negative for bacterial, fungal, and acid-fast bacilli cultures. Pathology from the transbronchial biopsy showed atypical epithelioid cells in intravascular spaces.

Atrial fibrillation (AF) is a common complication of sepsis. It is unclear whether norepinephrine, an α- and β-agonist, and phenylephrine, an α-agonist, are associated with different heart rates among patients with sepsis and AF. ⋯ In patients with sepsis and AF, the initiation of phenylephrine was associated with modestly lower heart rate compared with norepinephrine. Heart rate at vasopressor initiation appeared to be an important effect modifier. Whether modest reductions in heart rate are associated with clinical outcomes requires further study.

Asthma exacerbations can be life-threatening, with 25,000 to 50,000 such patients per year requiring admission to an ICU in the United States. Appropriate triage of life-threatening asthma is dependent on both static assessment of airway function and dynamic assessment of response to therapy. Treatment strategies focus on achieving effective bronchodilation with inhaled β2-agonists, muscarinic antagonists, and magnesium sulphate while reducing inflammation with systemic corticosteroids. ⋯ However, mechanical ventilation in these patients often requires controlled hypoventilation, adequate sedation, and occasional use of muscle relaxation to avoid dynamic hyperinflation, which can result in barotrauma or volutrauma. Sedation with ketamine or propofol is preferred because of their potential bronchodilation properties. In this review, we outline strategies for the assessment and management of patients with acute life-threatening asthma focusing on those requiring admission to the ICU.
