To explore the effect of a modified ice pack on physical cooling of patients with high fever in Emergency Department of Internal Medicine.

A total of 132 hyperthermia patients treated with physical cooling by ice pack in Emergency Department of Internal Medicine, the First Affiliated Hospital of Anhui Medical University from June to October in 2016 were selected and divided according to random number table method into observation group (n=67) and control group (n=65) . In the observation group, physical cooling was realized by modified ice pack, while in the control group, by the traditional ice bag. After 30 minutes of physical cooling, body temperature changes of patients were recorded. The data was collected by self-designed questionnaires. Application effect was evaluated from the aspects of range of body temperature decrease, humidity rate, displacement rate, compliance and satisfaction.

Range of body temperature decrease of patients in the observation group was larger than that in the control group (P<0.05) ; humidity rate and displacement rate in the observation group were lower than those in the control group, and compliance and satisfaction were higher than those in the control group (P<0.05) .

With low humidity rate, low displacement rate, high compliance and high satisfaction of patients, cooling effect of the improved ice pack is better than traditional ice pack to patients with acute high fever, which makes it worth promoting in clinic.
