The clinical efficacy of Shengyu decoction in the treatment of anemia after PFNA for elderly intertrochanteric fracture

Femoral intertrochanteric fractures (ITF) occur frequently in the elderly, accounting for 45% of all hip fractures. Postoperative anemia after fracture tends to cause ischemia, hypoxia in cells, tissues and organs, increasing the rate of blood transfusion, risk of infection, disability and mortality. Meanwhile, traditional Chinese medicine is widely used in the treatment of anemia for activating blood circulation and removing blood stasis.This study is a prospective, outcome assessor-, and data analyst-blinded randomized controlled clinical trial. The objective of this proposed study was to investigate whether Shengyu Decoction could improve the symptoms of anemia after proximal femoral nail antirotation in elderly ITF patients. After qualifying for screening, patients will be randomized into 2 groups with an allocation ratio of 1:1. Hemoglobin concentration, HBL, and HHS score are outcome measurements. The other outcomes also included time to get out of bed, discharge to home, 30-day readmission rates, and mortality.ITF is commonly occurring in senior citizens, and those who are senior in age generally suffer 1 or more basic diseases, whose nutritional status is already poor. Trauma and surgical stimulation not only aggravate the existing disease or induce corresponding cardiovascular complications, but also worsen the nutritional status, which can easily cause postoperative anemia in patients. Because of the limited clinical modalities available for the treatment of postoperative anemia after fracture surgery, and most of them have various side effects that are not easily tolerated by the elderly. Therefore, from a traditional Chinese medicine perspective, we proposed a protocol using mild Chinese herbal decoction to treat postoperative anemia in ITF.Registration number: OSF Registration number: DOI 10.17605/OSF.IO/JQ6ZF.
