目的：探讨人工关节置换术后低氧血症的发生规律，提出护理对策。方法监测2013年1—4月行人工关节置换术患者100例的围术期指尖血氧饱和度（ SpO2），进行曲线描记，对不同手术类型患者围术期SpO2变化进行对比研究。结果人工关节置换术患者围术期SpO2变化曲线几近一致， SpO2最低值主要集中在手术当日，术后第1～2天表现为明显的低氧血症，在第3～5天表现出平稳上升恢复的趋势；单侧膝关节置换术患者在手术当日及术后第1天SpO2检测值分别为（91．9±2．5）％和（92．9±2．0）％，均低于单侧髋关节置换术患者[（93．3±2．2）％、（93．7±2．0）％]，差异有统计学意义（t值分别为－2．789，－2．231；P＜0．05）。结论人工关节置换术患者围术期SpO2的变化有一定的规律，术后1d容易发生无症状性低氧血症，尤以膝关节置换术为著，应加强护理干预，预防低氧血症的发生。

Objective To find out the law of occurrence, clinical characteristics and interventions of hypoxemia after artificial joint replacement.Methods From January to April 2013, totals of 100 patients underwent artificial joint replacement and were retrospectively analyzed.Perioperative pulse oximetry ( SpO2 ) was measured and recorded its curved line, and then we compared Perioperative changes of SpO2 curve for different types of surgery.Results During perioperative period, the curves of SpO2 were stable and nearly consistent.After operation, the lowest value of SpO2 usually happened in the first day, and patients usually performed hyoxemia in one to two days;but the value of it would steady increase to normal in three to five days. For unilateral joint replacement patients, the values of SpO2 were one to two days after operation and three to five days after operation(91.9 ±2.5)%,(93.7 ±2.0)% which were less than the unilateral hip replacement [(93.3 ±2.2)% and (93.7 ±2.0)%](t=-2.789,-2.231,respectively;P<0.05).Conclusions For artificial joint replacement in perioperative period, the change of SpO2 has certain law that hyoxemia normally occur in the first day after operation especially for knee replacement patients.Medical staff should enforce nursing intervention to prevent it.
