Comparative Study
Comparison of heparinized and nonheparinized solutions for maintaining patency of arterial and pulmonary artery catheters.
Arterial and pulmonary artery catheters are often used in the management of critically ill patients. If heparin were not necessary to maintain the patency of arterial and pulmonary artery catheters, these patients could avoid exposure to heparin. ⋯ The failure rate of pulmonary artery catheters was not affected by the use of nonheparinized solutions. Arterial catheters failed less often when they were maintained with heparinized solutions. The authors recommend that all arterial catheters be maintained with heparinized solutions, unless use of heparin is contraindicated.

Randomized Controlled Trial Comparative Study Clinical Trial
Rewarming cardiac surgical patients: warm water vs warm air.
Hypothermia is experienced by 60% to 90% of adult patients after surgery. The detrimental physiological consequences of prolonged hypothermia are a significant risk for cardiac surgical patients. ⋯ The data suggest that rewarming with a circulating-water blanket produces normothermia more rapidly than rewarming with a warm convective-air blanket in adult patients who are hypothermic after cardiac surgery.

Although sleep is important for physical and psychological health, no research has assessed the sleep of children in a pediatric ICU and the factors that affect sleep. ⋯ Patients in the pediatric ICU sleep significantly less than is normal for children of the same ages, and their patterns of sleep are seriously disturbed. Because noise, light, and contact with caregivers are significant predictors of sleep state, health professionals can use these findings to structure the environment and the care they give to promote the sleep of critically ill children.
