Dai et al reported risk factors for blood transfusion of an older adult with a traumatic femoral intertrochanteric fracture. The authors are from Affiliated Dongyang Hospital of Wenzhou Medical University in Dongyang, China.
Patient selection: age > 60 years, with intertrochanteric fracture
Tranfusion protocols used at institutions:
(1) preoperative transfusion: hemoglobin <= 90 g/L
(2) intraoperative transfusion: hemoglobin < 80 g/L
(3) postoperative transfusion: hemoglobin < 80 g/L
Predictors for blood transfusion:
(1) older age (mean nontransfused 77.7 +/- 8.7 vs 82.1 +/- 7 transfused)
(2) unstable fracture type (stable or unstable based on classification of Evans, modified by Jensen and Michaelsen)
(3) admission hemoglobin in g/L (mean nontransfused 117.5 +/-11.2 vs 99.5 +/- 11.5 transfused)
where:
• The table reports hemoglobin in mmol/L. However, the values given are too high for those units. They would be appropriate for g/L/
