ABSTRACT
One hundred fifty-three patients with hypoxia of both sexes,underwent hip arthroplasty from January 2012 to January 2014,aged 65-97 yr,weighing 41-80 kg,living in areas at altitude above 1800 m,of American Society of Anesthesiologists physical status Ⅱ-Ⅵ,were selected.The hemoglobin (Hb) at 3-4 days after operation was collected,and the patients were divided into 3 groups depending on whether or not postoperative anemia occurred:no anemia group (Hb＞ 110 g/L);mild anemia group (90 g/L≤ Hb≤ 110 g/L);moderate anemia group (70 g/L ≤ H b＜ 90 g/L).The 36-item Short-Form Health Survey score and Harris Hip Score at 28 days after operation were collected.There was no significant difference between the three groups in the postoperative 36-item Short-Form Health Survey score and Harris Hip Score (P＞0.05).Postoperative mild and moderate anemia did not affect the short-term outcome after hip arthroplasty in elderly patients in high-altitude regions.
