Geriatric hip fracture is an important disease that affects the health life of the elderly in
China. Geriatric hip fracture is often complicated by a variety of comorbidities due to
advanced age. And anemia is a common comorbidity. At present perioperative management of
geriatric hip fracture, transfusion is only indicated for moderate and severe anemia, while
no special medical intervention for mild anemia in China. More and more studies have found
that iron can not only correct anemia, but also improve cardiac function, patients' quality
of life and function. This study investigated the effect of perioperative iron
supplementation on activity tolerance in elderly patients with hip fracture complicated with
iron deficiency anemia. The study was a randomized, parallel controlled clinical study. Due
to the requirements of the ethics committee, the unblinded setting was cancelled due to
ethical considerations. Research will be grouped according to whether to accept iron
supplementation treatment, are divided into 2 groups, respectively, iron treatment group and
the traditional method. The method of randomization was stratified block randomization. The
experimental group added to the intravenous iron sucrose during perioperative period
according to the degree of iron deficiency. If there is still a iron deficiency or anemia at
discharge, oral ferrous lactate is added after discharge. The outcomes include 6-minute walk
distance, Harris score, EQ-5D score six months after surgery, perioperative blood transfusion
rate, and so on in the two groups.
