A previous retrospective study suggested that an anemia prevention may shorten hospitalization and improve recovery, stating the usefulness of a proper therapy for preventing anemization, in order to get a better functional recovery and reduce hospitalization length. The present study analyzed the association of preoperative and postoperative hemoglobin levels with rehabilitation outcomes to check these results in the Rehabilitation Unit.
The study enrolled 104 patients, 94 underwent hip replacement surgery and 10 knee replacement. Patients were functionally studied through the six-meter walking test (6MWT) at admittance and at discharge from the Rehabilitation Unit.
Preoperative hemoglobin has no correlation either with the results of WT executed at discharge nor with the improvement of it compared to the WT executed at admittance, while there is a significant relationship with the results of the WT executed at admittance. Age impacts on the result of 6MWT at admittance, on the one at discharge and on the improvement as well.
Despite movement weakening by anemization due to surgery, patients transferred to the Rehabilitation Unit after total hip- and knee replacement, are able to get a better movement performance independently on hemoglobin loss.
先前的回顾性研究表明，贫血预防可能会缩短住院时间并促进康复，这表明适当的治疗对于预防贫血症的发生是有用的，以获得更好的功能恢复并缩短住院时间。本研究分析了术前和术后血红蛋白水平与康复结果的关系，以在康复单元中检查这些结果。
该研究纳入了 104 名患者，其中 94 名接受了髋关节置换手术，10 名接受了膝关节置换手术。患者通过入院时和离开康复单元时的 6 米步行测试（6MWT）进行功能研究。
术前血红蛋白与出院时执行的 WT 结果以及与入院时执行的 WT 相比的改善均无相关性，而与入院时执行的 WT 结果有显著关系。年龄会影响入院时的 6MWT 结果、出院时的结果以及改善程度。
尽管手术导致贫血会削弱运动能力，但接受全髋关节和膝关节置换后转入康复单元的患者能够独立于血红蛋白丢失获得更好的运动表现。
