Effect of erythropoietin on hemorrhage of hip replacement surgery / 中国生化药物杂志

ABSTRACT

Objective To investigate the effect of erythropoietin on hemorrhage in hip replacement surgery .Methods 48 cases undergoing elective hip replacement surgery in our hospital From June 2014 to October 2016 were selected and devided into control group and experimental group according to the conditional similarity, 24 cases in each group, then the application of erythropoietin in hip replacement surgery was explored.For the experimental group, erythropoietin was injected subcutaneously at three, five and seven days before operation, the dose was 250 U/(kg· times).The control group received 0.9%sodium chloride injection of the same volume of saline, and the other treatments were the same as in the experimental group.Preoperative situation, hemoglobin (Hb) levels, blood pressure (diastolic pressure and systolic blood pressure) at one day before surgey and three, seven and 14 days after surgey were compared and analyzed.Results There were no significant difference in body weight, hemoglobin (Hb), and age between the two groups before operation.The levels of Hb in the experimental group and the control group at 3 and 7 days after operation were compared, the difference was statistically significant (P<0.05), 14 days after the surgey, Hb returned to normal in the experimental group, while the Hb level in the control group was still significantly lower than that in the control group before surgey, the difference was statistically significant (P<0.05).There was no significant difference in diastolic blood pressure and systolic blood pressure between the two groups.Conclusion Preoperative erythropoietin mobilization in patients with hip replacement surgery can reduce the amount of bleeding during and after operation , and the adverse reactions are not obvious.
