Risk factors of the peri-operative hidden blood loss in artificial femoral head replacement
To investigate the risk factors of peri-operative hidden blood loss in the artificial femoral head replacement.
Methods
2
Retrospective analysis was conducted on the clinical data of 106 patients who underwent artificial femoral head replacement in our hospital from January 2019 to August 2022. The peri-operative hidden blood loss was calculated according to Gross equation. The peri-operative condition of the patients was counted. The univariate analysis was used to determine the factors related with peri-operative hidden blood loss. Indicators with statistically significant differences in univariate analysis were included in the multivariate
Logistic
regression analysis model to screen out the independent risk factors for peri-operative hidden blood loss.
Results
2
The mean hemoglobin levels before surgery and 72 hours after surgery were (103.44±15.67)g/L and (85.65±14.53)g/L respectively, with a statistically significant difference between them (
t
=16.650,
P
<
0.05).The mean peri-operative hidden blood loss was (262.43±85.79)mL. There were 94 patients with anemia,with an incidence of 88.68%. Twenty-nine patients received blood transfusions,with an transfusion rate of 27.36%. The univariate analysis showed that peri-operative hidden blood loss was related to age,fracture type,time from injury to surgery,preoperative anticoagulation (
P
<
0.05). Multivariate
Logistic
regression analysis revealed that age≥80 years old,intertrochanteric femur fracture, time from injury to surgery≥5 days, and preoperative anticoagulation were independent risk factors for peri-operative hidden blood loss in artificial femoral head replacement (
P
<
0.05).
Conclusion
2
Peri-operative hidden blood loss in artificial femoral head replacement is affected by a variety of factors, and its risk factors include age≥80 years old,intertrochanteric femur fracture, time from injury to surgery≥5 days, and preoperative anticoagulation. Patients with the above symptoms should be paid clinical attention and intervention should be initiated as early as possible to avoid peri-operative hidden blood loss and improve the prognosis of patients.
