Analysis of hypothermia factors for elderly patients with malnutrition during proximal femoral nail antirotation internal fixation under general anesthesia
To analyze the incidence and risk factors of hypothermia in elderly patients with malnutrition during proximal femoral nail antirotation (PFNA) internal fixation under general anesthesia.
Methods
2
A total of 139 elderly patients underwent PFNA internal fixation under general anesthesia were selected,and the nutritional status scores 1 day before surgery ranged from 0 to 11 points. Univariate and multivariate
Logistic
binary regression analysis was performed to analyze the related factors that may lead to intraoperative hypothermia.
Results
2
Among 139 elderly patients with preoperative nutritional scores of 0 to 11 points,79 cases (56.83%) developed intraoperative hypothermia. The results of univariate and multivariate
Logistic
binary regression analysis suggested that age≥75 years old,mini nutritional assessment short form (MNA-SF) nutritional score 0 to 7 points,BMI

,duration of general anesthesia ≥2 hours,intraoperative flushing fluid volume≥1 000 mL and intraoperative fluid volume≥1 000 mL were the risk factors for the occurrence of intraoperative hypothermia in elderly patients (

Conclusion
2
The incidence of intraoperative hypothermia during PFNA internal fixation under general anesthesia in elderly patients with mainutrition before operation is high,and patients with poor nutritional status are more likely to develop intraoperative hypothermia. Patients with older age,poor nutritional status,lower BMI,longer duration of general anesthesia,and more intraoperative flushing fluid volume and intraoperative fluid volume are likely to lead to intraoperative hypothermia. The use of warm blanket can reduce the incidence of intraoperative hypothermia.
