Objective To analyze the related factors of hidden blood loss in elderly patients with intertrochanteric fracture of femur (IFF) during perioperative period.
Methods A total of 110 elderly patients with IFF who received surgical treatment were selected as research subjects, the hidden blood loss of patients was recorded on the first day before admission and third day after operation, the baseline data filling form was designed to record the related baseline data of patients, the hidden blood loss of patients with different characteristics of data was compared, the related factors that might affect the hidden blood loss in elderly patients with IFF were analyzed.
Results Of 110 elderly patients with intertrochanteric fracture of femur, the average total perioperative blood loss was (913. 62±169.84) mL, and the preoperative hidden blood loss was (254.91±57.83) mL and the hidden blood loss was (795.20±128.75) mL; the hidden blood loss of elderly patients with IFF combined with underlying diseases, type A3 of fracture, intramedullary fixation and general anesthesia was higher than that of patients without underlying diseases, type A1 and A2 of fracture, extramedullary fixation, the differences were statistically significant (P < 0.05); there was no statistically significant difference in the amount of hidden blood loss in elderly IFF patients with differed characteristics during perioperative period (P>0.05); the results of multiple linear regression analysis showed that combining with underlying diseases, type A3, intramedullary fixation were the influencing factors of more hidden blood loss in elderly patients with IFF (P < 0.05).
Conclusion Combining with underlying diseases, type A3 of fracture, and intramedullary fixation are the influencing factors of hidden blood loss in elderly patients with IFF.
