Abstract
Objective To explore the effect of gender and internal fixation method on perioperative hidden blood loss in elderly patients with intertrochanteric fractures.Methods 80 elderly patients with intertrochanteric fractures in our hospital from May 2014 to July 2016 were selected and divided into group A and group B according to different internal fixation methods.45 cases in the group A were treated by dynamic hip screw,while 35 cases in the group B were treated by proximal femoral nail anti-rotation.Observed the hidden blood loss at the perioperative period of the two groups and its correlation with the intemal fixation method and the gender.Results The amount of hidden blood loss of the group A [(338.5±23.7)ml] was significantly lower than that of the group B [(445.8± 16.2) ml],with statistically significant difference (P＜0.05).The amount of hidden blood loss of the male patients was significantly lower than that of the female patients in both two groups,with statistically significant differences (P＜0.05).The amount of dominance blood loss of the group A [(197.2±17.9)ml] was higher than that of the group B [(125.7±13.1)ml],and the total amount of blood loss of the group A [(535.8±16.7)ml] was lower than that of the group B [(572.2±15.5)ml],with statistically significant differences (P＜0.05).The gender (OR=3.027,P=0.040) and the internal fixation method (OR=2.323,P=0.043) were correlated with hidden blood loss,with statistically significant differences (P＜0.05).Conclusions The hidden blood loss of the elderly male patients was less than that of the female patients,and the hidden blood loss of the patients treated by dynamic hip screw was less than that of the patients treated by proximal femoral nail anti-rotation.The gender and the internal fixation method were closely related to the hidden blood loss at the perioperative period of elderly patients with intertrochanteric fractures.关键词
