Abstract: Objective: To investigate current status of temperature protection during the operations, and to provide the corresponding basis for the intervention. Methods: The patients who had surgeries in a tertiary Grade A hospital during 2015.1.1-6.30 were recruited by convinience sampling method. The questionnaire designed by the researchers was used to collect the data. Results: Totally 9 369 cases were data-collected. About 4 764 (50.8%) patients were taken temperature protection. About 1 353 (53.4%) patients who were older than 60 years old were taken temperature protection and the rate was higher than that in other age group (P<0.01). The ratio of keeping warm in different departments had significant difference (P<0.05). Among all methods of temperature protection, the warming blankets or warm air heater were used most frequently. Conclusion: The active warming measures during the operation is relatively low. It is very important to promote the awareness of warming patients actively, take different measures to maintain the stability of the patient's temperature, and to pay more attention to the elders.
