Predictive value of blood glucose gap for perioperative blood transfusion in elderly patients with lower limb fracture surgery
Objective:To investigate the predictive value of blood glucose gap for perioperative blood transfu-sion in elderly patients undergoing lower limb fracture surgery.Methods:From January 2020 to November 2020,161 elderly patients with lower extremity fractures who underwent elective surgery in our hospital were selected,patients were divided into transfusion group(n=38)and non-transfusion group(n=123)according to whether or not they received blood transfusion during the perioperative period.The clinical data of the two groups were com-pared,and the ROC curve was drawn to analyze the predictive value of blood glucose gap for perioperative blood transfusion in elderly patients with lower extremity fracture.Results:Multivariate logistic regression analysis showed that age(OR=3.255,95％CI 1.078-9.832),BMI(OR=1.688,95％CI 0.958-2.974),operation time(OR=1.792,95％CI 0.880-3.650),Hb(OR=3.469,95％CI 1.799-6.689),blood glucose gap(OR=2.827,95％CI 1.432-5.581)were the important influencing factors of blood transfusion in the elderly patients with lower extremity fracture during perioperative period(P＜0.05).The results of ROC curve analysis showed that the area under the curve of age,BMI,operation time and GG in predicting perioperative blood transfusion in elderly pa-tients with lower limb fracture were 0.629,0.677,0.637 and 0.774,respectively,among which GG had the best predictive value.Conclusion:Blood glucose gap prediction of perioperative blood transfusion in elderly patients with lower extremity fracture may have good efficacy,and have advantages of easy access,simple calculation,and can provide reference for clinical identification of high blood transfusion population.
