Comparing the effectiveness of two types of cooling blankets for febrile patients.

A randomized controlled trial was conducted to compare the effectiveness of airflow- and waterflow-cooling blankets for febrile patients in intensive care unit. More patients in the airflow than in the waterflow-cooling blanket group reached the desired temperature of <38 degrees C at the end of 8h (94.1 versus 60.0%, chi2=2.86, P=0.047). Patients in the airflow blanket group also took less time than those in the waterflow blanket group to achieve the desired temperature (3.1 and 5.7h, respectively, U=2.00, P<0.001). These findings suggest that the airflow blanket is the cooling blanket of choice for febrile patients when external cooling is needed.
