Objective : To explore the effect of evidence-based nursing in preventing perioperative hypothermia of patients undergoing thoracotomy .Methods : A total of 60 patients ,who were scheduled for thoracotomy with general anesthesia during August 2013 and May 2014 ,were selected and randomly divided into the evidence-based group and the control group with 30 cases in each .While the control group was treated with routine insulation measures ,the evidence-based group received warming with inflatable heating blanket .The changes of intraoperative body temperature in two groups were observed and recorded . The extubation time ,amount of bleeding ,incidence rate of shivering ,and situation of incision infection were compared between the two groups .Results : There was no significant difference between the two groups regarding general information .The body temperature of different time points in evidence-based group was significantly higher than that in control group one hour after surgery (P< 0 .05) .There were statistically significant differences regarding the amount of bleeding ,the time of extubation , the incidence rate of postoperative shivering ,and the rate of incision infection between the two groups (P< 0 .05) .Conclusions :Evidence-based nursing practice are conducive to reducing the incidence rate of intraoperative hypothermia in patients undergoing thoracotomy .It can also promote anesthesia recovery ,reduce the amount of bleeding ,and decrease the incidence rate of wound infection and shivering .It is worthy of clinical application .

Objective:To compare three kinds of stress injury risk factors assessment scales during intraoperative period, and to provide evidence for the prevention of intraoperative stress injury.Methods:Three assessment tools (Waterlow Risk Factor Assessment Scale, Munro Pressure Ulcer Assessment Scale and Scott Triggers Evaluation Scale) were used to assess the risk degree of 173 surgical patients in the Operating Room of Zhongshan Hospital Affiliated to Fudan University from January 2018 to June 2019. After the operation, a whole-body skin examination was performed to record the occurrence of pressure ulcer, and the reliability, validity, and prediction effect of every scale were compared.Results:The retest reliability of Scott Triggers Evaluation Scale and Munro Pressure Ulcer Assessment Scale was respectively 0.932 and 0.992, the expert content validity was respectively 0.759 and 0.705, the calibration correlation validity was respectively 0.381 and 0.190, the sensitivity was respectively 0.74 and 0.32 and specificity was respectively 0.58 and 0.89. The area under the ROC curve of Scott Triggers Evaluation Scale and Munro Pressure Ulcer Assessment Scale was larger than that of Waterlow Risk Factor Assessment Scale, which was 0.714 and 0.711, respectively.Conclusions:Scott Triggers Evaluation Scale and Munro Pressure Ulcer Assessment Scale can be used to evaluate the stress injury of surgical patients. At the same time, Scott Triggers Evaluation Scale is more accurate and convenient than the Munro Pressure Ulcer Evaluation Scale. Thus, Scott Triggers Evaluation Scale is recommended for clinical application.
