Objective To know the influence of heat preservation intervention on temperature among aged patients who had accepted abdomen surgery. Methods Divided 40 aged patients into the heat preservation group and the routine temperature group, there were 20 cases in the each group. Heat preservation intervention were used in the heat preservation group, while the routine nursing cares were used in the routine temperature group. Compared the incidence rate of shivering and the changing of temperature during the course of operation between the two groups. Results There was no significant difference in the heat preservation group about changing of temperature during the course of operation, while the difference in the routine group was significant. The incidence rate in the shivering in routine group was significant higher than that of in the beat preservation group. Conclusions It is necessary for aged patents about heat preservation during the operation, which can avoid low body temperature and promote satisfactory prognosis.
