An analysis of peri-operative hidden blood loss after emergency operation for intertrochanteric fracture of femur in elderly patients

Objective: To evaluate the preliminary usage of PFN in surgical treatment of intertrochanter fractures caused by osteoporosis in old patients and to explore peri- operative hidden blood loss following emergency operation. Methods: Twenty-eight patients treated with PFN,from January 2011 to January 2013,with comminuted intertrochanter fracturescaused by osteoporosis were studied. Peri- operative hidden blood loss were analyzed. PFN was implanted by closed reduction and mini incision. Results: The mean hidden blood loss was 811 m L,the mean observed blood loss was 92 m L,the mean total blood loss was903 m L,each accounts for 10. 2% and 89. 8% in total blood loss,hidden blood loss was much more than observed blood loss.There were no difference between male and female group,obesity and normal group. Conclusion: Hidden blood loss was the major part of total blood loss after emergency operation for intertrochanteric femur fracture. It is very important to supplement the blood volume during peri- operative period. The gender and obesity are not the risk factors of the hidden blood loss.
