Abstract：Objective To analyze the overt and occult blood loss before and after operations in the elderly intertrochanteric fracture treated with intramedullary fixation and extramedullary fixation to provide data support for perioperative period treatment .Methods The clinical data of 64 cases of intertrochanteric fracture treated with ex-tramedullary fixation and 87 cases treated with intramedullary fixation from Jan .2010 to Dec.2013 were retrospec-tively analyzed , and the overt ,occult blood loss and blood transfusion before and after opertations were analyzed ,u-sing SPSS 13.0 statistical package.Results In the intramedullary fixation group,the average blood loss was (65.7 ±3.4)ml during operation.The average overt blood loss was (70.4 ±4.6)ml after operation and the average oc-cult blood loss was (431.6 ±17.8) ml.In the extramedullary fixation group ,the average blood loss was (94.5 ± 7.4)ml during operation.The average overt blood loss was (80.4 ±4.7)ml and the occult blood loss was (298.4 ±5.3)ml after operation.The blood loss during operation and overt blood loss after operation in the extramedullary fixation group was larger than that of the intramedullary fixation group ,while the occult blood loss of the extramedul-lary fixation group was smaller than that of the intramedullary fixation .The total blood loss and the occult blood loss of the intramedullary fixation gronp was bigger than that of the extramedullary fixation group .Conclusion There is much occult blood loss in both two groups for the internal fixation of the intertrochanteric fracture after operation , but more occult blood loss in the intramedullary fixation group .This reminds surgeons to monitor the life vital signs after internal and external fixation in order to decrease the complication .
