title: [Risk factors of perioperative blood loss in elderly patients receiving proximal femur locking compression plate fixation for intertrochanteric fractures].
abstract: OBJECTIVE
  To analyze the risk factors of perioperative blood loss in elderly patients with intertrochanteric fractures treated with proximal femur locking compression plate (PFLCP) fixation.
  
  
  METHODS
  A retrospective analysis was carried out in an cohort of 178 elderly patients undergoing PFLCP fixation for intertrochanteric fractures between February 2010 and December 2014. The preoperative and postoperative blood biochemistry, intraoperative and postoperative of blood loss and blood transfusion were analyzed, and the impact of the factors including age, height, body weight, complications, and operation time was evaluated on perioperative blood loss.
  
  
  RESULTS
  The average volume of perioperative blood loss was 637.67 ± 251.57 mL, mean operating time was 130.93 ± 31.02 min, and recessive blood loss was 240.51 ± 195.92 mL in these patients. The volume of perioperative blood loss was associated with the patients' age and the operating time but not with body weight, height, gender, or hypertension.
  
  
  CONCLUSIONS
  Large volume of blood loss may occur in elderly patients undergoing PFLCP fixation for intertrochanteric fractures in close relation with the patient's age and the duration of operation.
