To determine if peripheral venous blood gas values for pH, partial pressure of carbon dioxide (Pco(2)) and the resultant calculated bicarbonate (HCO(3)) predict arterial values accurately enough to replace them in a clinical setting. ⋯ Arterial and venous blood gas samples were strongly correlated, and there were only small differences between them. A survey of emergency physicians suggested that the differences are too large to allow for interchangeability of results; however, venous values may be valid if used in conjunction with a correction factor or for trending purposes.

Although temporal lobectomy is an effective alternative treatment for many patients with medication-resistant epilepsy, the risk of cognitive morbidity is not inconsequential. The ability to predict cognitive outcome is increasingly dependent on convergent information from multiple sources, including direct (e.g., Wada test) and indirect (e.g., psychometric testing) functional assessments along with magnetic resonance imaging studies that detect structural abnormalities. This brief review summarizes the relationship between imaging and function at baseline and predicting cognitive outcome following temporal lobectomy.

Treatment and toxicokinetics of acute pediatric arsenic ingestion: danger of arsenic insecticides in children.
To describe the toxicokinetics and management of acute pediatric arsenic ingestion. ⋯ Recovery from arsenic poisoning was attributable to the restoration and maintenance of adequate cardiac output and renal perfusion in early shock, which allowed depot intramuscular British anti-Lewisite to circulate and eliminate the poison. Although an intravenous antiarsenical chelating agent would be advantageous in treating shock from arsenic poisoning, none is currently available. We urge the immediate use of British anti-Lewisite therapy on patient presentation with suspected toxic arsenic ingestion.

To compare patient, nurse, and physician assessments of quality of care and patient satisfaction in selected critical care units. ⋯ Patients, nurses, and physicians viewed quality of care and patient satisfaction differently. Nurses' and physicians' perspectives were more related to their views of the work environment than to organizational factors, patient characteristics, or commonly used outcome measures.
