RESUMO
Objective To explore the effects of insulation measures on blood coagulation during laparotomy in the aged patients. Methods Sixty patients were randomly divided into the experimental group and the control group with 30 cases in each group from September 2007 to August 2008. The experimental group received a series of insulation measures based on general perioperative nursing care, which was given to the control group. Patients' temperature, platelet count (PLT), prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TV),fibrinogen (Fbg) were measured and these preand postoperative values together with blood loss during operation were compared between two groups. Results No significant change was seen in perioperative body temperature in the experimental group, the incidence rate of hypothermia was lower, the change in coagulation index was better than that of the control group. Conclusions These results suggested that mild hypothermia could influence aged patients' blood coagulation function and increase blood loss during laparotomy. Active insulation measures can maintain the stability of patients" temperature.
