Review Case ReportsAcute respiratory distress syndrome from chlorine inhalation during a swimming pool accident: a case report and review of the literature.
Chlorine inhalation can result in significant morbidity and mortality. The most common clinical ramification is mucosal irritation. Rarely, depending upon the degree of exposure, patients can develop acute respiratory distress syndrome. ⋯ Despite limited data to support the decision, the patient was started on treatment with corticosteroids. She recovered completely from her illness and was discharged home without supplemental oxygen. A concise discussion of chlorine inhalation injury and a literature review on the utility of inhaled and/or systemic corticosteroids for this clinical entity is presented.

Fungal infections are increasing nationwide, paralleling increases in the number of immunosuppressed hosts. Most of the candida infections seen in the intensive care unit are likely due to iatrogenic factors such as hyperalimentation, catheters, broad-spectrum antibiotics, and postprocedure complications that are prevalent in intensive care unit patients. Delays in appropriate therapy are common and may compromise care. ⋯ The issue of antifungal prophylaxis has to be balanced against issues of resistance, and current guidelines are reviewed here for prophylactic use of fluconazole only in selected intensive care unit patients. Finally, several new antifungal agents are available to treat the emerging resistant fungi, with better toxic/therapeutic ratios than in the past. Thus, there are an increasing number of safer and more effective options for treating fungal infections in the intensive care unit.

Transfusion-related acute lung injury (TRALI) refers to a clinical syndrome of acute lung injury that occurs in a temporal relationship with the transfusion of blood products. Because of the difficulty in making its diagnosis, TRALI is often underreported. Three not necessarily mutually exclusive hypotheses have been described to explain its etiogenesis: antibody mediated, non-antibody mediated, and two hit mechanisms. ⋯ Diuretics are generally not indicated, as hypovolemia should be avoided. Compared with many other forms of acute lung injury, including the acute respiratory distress syndrome, TRALI is generally transient, reverses spontaneously, and carries a better prognosis. A variety of prevention strategies have been proposed, ranging from restrictive transfusion strategies to using plasma derived only from males.

ReviewNonventilatory interventions in the acute respiratory distress syndrome.
Acute respiratory distress syndrome was first described in 1967. Acute respiratory distress syndrome and acute lung injury are diseases the busy intensivist treats almost daily. The etiologies of acute respiratory distress syndrome are many. ⋯ Most of these therapies either have not been studied in large trials or have failed to show a benefit in terms of long-term patient mortality. Many of these therapies have shown promise in terms of improved oxygenation and may therefore be beneficial as rescue therapy for severely hypoxic patients. Recommendations regarding the use of each of these strategies are made, and an algorithm for implementing these strategies is suggested.

Overt status epilepticus and persistent obtundation after a witnessed clinical seizure are neurologic emergencies. Early recognition and intervention in the electroclinical syndrome of status epilepticus reduces morbidity, although treatment of the underlying etiology is also critical. ⋯ This review is written from the perspective of the intensive care unit clinician, and the approach and opinions expressed stem from clinical experience and review of the current literature. Particular attention is given to an overall approach to the management of convulsive status epilepticus in adults and older children as well as exploring novel approaches and diagnostic tools that may prove useful in difficult-to-control status epilepticus.
