Review Case ReportsThe effect of statutory limitations on the authority of substitute decision makers on the care of patients in the intensive care unit: case examples and review of state laws affecting withdrawing or withholding life-sustaining treatment.
While the ethics and critical care literature is replete with discussion of medical futility and the ethics of end-of-life care decisions in the intensive care unit, little attention is paid to the effect of statutory limitations on the authority of substitute decision makers during the course of treatment of patients in the critical care setting. In many jurisdictions, a clear distinction is made between the authority of a health care power of attorney, who is legally designated by a competent adult to make decisions regarding withholding or withdrawing life-sustaining treatment, and of next-of-kin, who are limited in this regard. However, next-of-kin are often relied upon to consent to necessary procedures to advance a patient's medical care. ⋯ In this article, we will provide case examples of how statutory limitations on substitute decision making authority for next of kin can impede the care of patients. We will also review the varying jurisdictional limitations on the authority of substitute decision makers and explore their implications for patient care in the critical care setting. Finally, we will review possible ethical and legal solutions to resolve these impasses.

ReviewPercutaneous tracheostomy at the bedside: 13 tips for improving safety and success.
We have developed a set of routines and practices in the course of performing a large series (n = 70) of percutaneous dilational tracheostomy (PDT). The 13 tips discussed in this review fall into 4 categories. System factors that facilitate training, patient safety, and avoidance of crises including the use of appropriate personnel, importance of timing, use of premedication, and the utility and content of a preprocedure briefing. ⋯ We also discuss the management of common postprocedure problems including tracheostomy tube obstruction, malposition requiring tube exchange or replacement, and air leak. The practical considerations for successful execution of PDT involve common sense, thorough planning, and structured approaches to prevent adverse effects if the procedure does not go as smoothly as expected. These strategies will aid anesthesiologists and intensivists in improving their comfort level, safety, and competence in performing this beside procedure.

Review Case ReportsSystemic lupus-induced diffuse alveolar hemorrhage treated with extracorporeal membrane oxygenation: a case report and review of the literature.
We report the case of a 28-year-old patient with systemic lupus erythematosus (SLE) with rapid onset of dyspnea and hemoptysis found to have diffuse alveolar hemorrhage (DAH) with refractory hypoxemia successfully treated with venovenous extracorporeal membrane oxygenation (ECMO). The discussion includes clinical presentation, diagnosis, management, outcome, and a review of the available adult literature on the use of ECMO in patients with DAH. ⋯ Diffuse alveolar hemorrhage secondary to SLE is quite rare. The adult literature on the utilization of ECMO for DAH is limited mostly to antineutrophil cytoplasmic antibody (ANCA)-associated alveolar hemorrhage and a few reports of nonvasculitis DAH. Bleeding has been a contraindication to ECMO due to the need for systemic anticoagulation. Our case, along with a review of the literature, indicates that ECMO with anticoagulation can be safely utilized in patients with DAH. To our knowledge, this is the first reported adult case of DAH due to SLE successfully treated with ECMO.

Auto-positive end-expiratory pressure (PEEP) is a common but frequently unrecognized problem in critically ill patients. It has important physiologic consequences and can cause shock and cardiac arrest. ⋯ Sedation and fluid management are important adjunctive therapies. This analytic review discusses the prevalence, pathophysiology, and hemodynamic consequences of auto-PEEP and an approach to its treatment.

ReviewIntravenous lipid emulsion for the treatment of drug toxicity.
Intravenous lipid emulsion (ILE) has emerged as a powerful antidote for the treatment of drug toxicity in the past decade. Initial efficacy of ILE was shown in the setting of local anesthetic systemic toxicity (LAST), but recent case reports suggest its consideration in a variety of other drug toxicities. ⋯ Specifically, we will look at the evidence for using ILE in LAST as well as toxicity due to beta-blockers, calcium-channel blockers, and tricyclic antidepressants. We will also review the current dosing recommendations as well as potential side effects of ILE as an antidote.
