Influenza A 2009 (H1N1) virus in admitted and critically ill patients.
The influenza A 2009 (H1N1) virus is a pandemic respiratory infection commanding international attention. More information is needed on patient demographics, illness severity, and risk indicators. ⋯ A high percentage of patients with H1N1 presented with underlying comorbid conditions including asthma and pregnancy. Traditional markers of pneumonia severity including CURB-65 score, Pneumonia Severity Index (PSI), serum lactate, and AG did not correlate with ICU admission in patients with H1N1. Strong ion gap effectively identified significant acid-base disturbances not identified by lactate or AG, however the trend of greater ICU admission rates among patients with elevated SIG did not reach statistical significance. Further study is needed to identify clinical tools to aid in risk-stratifying H1N1 patients.

Short-term outcomes in premature neonates adhering to the philosophy of supportive care allowing for weight gain and organ maturation prior to cardiac surgery.
Prematurity is a recognized risk factor for morbidity and mortality following cardiac surgery. The purpose of this study was to examine short-term outcomes following cardiac surgery in premature neonates adhering to our institutional philosophy of supportive care allowing for weight gain and organ maturation. ⋯ Early outcome seems independent of weight, prematurity, cardiopulmonary bypass, and type of first intervention. Importantly, there was no statistical difference in mortality between the 2 groups, regardless of how they were treated. Further long-term follow-up is needed in this patient population.

Posterior reversible encephalopathy syndrome (PRES) is characterized by headache, altered mental status, visual disturbances, and seizures. Radiological features typically include edema of the posterior cerebral regions, especially of the parietooccipital lobes. Atypical imaging features, such as involvement of anterior cerebral regions, deep white matter, and the brain stem are also frequently seen. ⋯ Treatment of severe hypertension, seizures, and withdrawal of causative agents represent the hallmarks of specific therapy in PRES. Delay in diagnosis and treatment may lead to permanent neurological sequelae. Therefore, awareness of PRES is of crucial importance for the intensivist.

Critical care management of major disasters: a practical guide to disaster preparation in the intensive care unit.
Recent events and regulatory mandates have underlined the importance of medical planning and preparedness for catastrophic events. The purpose of this review is to provide a brief summary of current commonly identified threats, an overview of mass critical care management, and a discussion of resource allocation to provide the intensive care unit (ICU) director with a practical guide to help prepare and coordinate the activities of the multidisciplinary critical care team in the event of a disaster.

Pandemic influenza: implications for preparation and delivery of critical care services.
In a 5-week span during the 1918 influenza A pandemic, more than 2000 patients were admitted to Cook County Hospital in Chicago, with a diagnosis of either influenza or pneumonia; 642 patients, approximately 31% of those admitted, died, with deaths occurring predominantly in patients of age 25 to 30 years. This review summarizes basic information on the biology, epidemiology, control, treatment and prevention of influenza overall, and then addresses the potential impact of pandemic influenza in an intensive care unit setting. Issues that require consideration include workforce staffing and safety, resource management, alternate sites of care surge of patients, altered standards of care, and crisis communication.
