Objective To explore the influencing factors of blood transfusion in patients with intertrochanteric fracture during perioperative period.

Methods Data of 281 cases with intertrochanteric fractures treated in Jinshan Hospital, Fudan University from January 2013 to January 2018 were collected, include gender, age, classification of fracture, hypertension, coronary heart disease, diabetes mellitus, cerebral infarction, preoperative levels of albumin, hemoglobin, platelet, and activated partial thromboplastin time (APTT), preoperative waiting days, surgical method, American Society of Anesthesiologists (ASA) classification and blood transfusion. The t test, rank sum test, χ² test and logistic regression were used for statistical analysis.

Results The transfusion rate was 45.20% (127/281). There were significant differences in gender, age, classification of fracture, diabetes mellitus, cerebral infarction, surgical method, ASA classification, preoperative waiting days and preoperative levels of albumin, hemoglobin, and platelet between the transfusion group and the non-transfusion group (P < 0.05). Multivariate logistic regression analysis showed that the influencing factors of blood transfusion were fracture type 4 or 5, preoperative hemoglobin < 90 g/L, history of cerebral infarction, and surgical method of artificial femoral head replacement or open reduction with proximal femoral nail antirotation.

Conclusions The influencing factors of perioperative blood transfusion of patients with intertrochanteric fracture include the classification of type 4 or type 5, preoperative hemoglobin < 90 g/L, history of cerebral infarction, artificial femoral head replacement or open reduction and proximal femoral nail fixation.
