The clinical courses of 63 survivors of cardiopulmonary arrest were reviewed to determine the incidence and temporal occurrence of noncardiac complications and their relationships to mortality. Complications were grouped as occurring within 48 hours or less, within 48 to 96 hours, or more than 96 hours after cardiopulmonary arrest. ⋯ Pneumonia and liver function test abnormalities were each significantly correlated with increased mortality. Septicemia, acute renal failure, and adult respiratory distress syndrome each occurred in three (5%) to four (7%) of the 63 patients and were always associated with mortality.

Randomized Controlled Trial Clinical Trial
Phosphate therapy in diabetic ketoacidosis.
To determine the efficacy of phosphate replacement in the therapy for diabetic ketoacidosis (DKA), 44 patients were randomly assigned to three treatment groups: those who received no phosphate replacement, those who received 15 mmole of sodium phosphate at the fourth hour, or those who received 15 mmole of sodium phosphate at 2, 6, and 10 hours. All patients were treated with intravenous insulin injection (0.1 units/kg/hr), fluids, and potassium. ⋯ Phosphate therapy did not affect the duration of DKA, dose of insulin required to correct the acidosis, abnormal muscle enzyme levels, glucose disappearance, or morbidity and mortality. Although theoretically appealing, phosphate therapy is not an essential part of the therapy for DKA in most patients.

The records of 40 patients with cancer and 684 patients without cancer admitted to a medical critical care unit were reviewed for the purpose of comparing survival. Patients with cancer had a higher mortality (55%, 22/40) than the patients without cancer (17%, 118/864). Patients with cancer and respiratory failure had a higher mortality (75%, 18/24) than patients without cancer but with respiratory failure (25%, 66/273) and a higher mortality than patients with cancer but without respiratory failure (25%, 4/16). ⋯ Patients with cancer but without respiratory failure had a mortality of 25% (4/16). All eight patients with cancer admitted to the hospital because of life-threatening metabolic disturbances survived. In deciding whether to apply critical care techniques to a patient with cancer, the physician should consider the specific nature of the life-threatening illness.
