Objective To investigate the effect of continuous quality improvement (CQI) on the prevention of acute pressure ulcer (PU) in major orthopedic surgery. Methods 244 cases underwent major orthopedic surgery in our hospital between January 2012 and January 2014 were selected and divided into group A and group B in accordance with the order of admission, with 122 cases in each. Group A received traditional care measures, group B received CQI preventive care measures. And the nursing effect of the two groups was compared. Results The preoperative PU assessment rate, PU knowledge awareness rate of nurses, correct place-ment rate of surgical position, rate of satisfaction with position placement in surgeons in group B was 97.54%, 95.08%, 93.44%, 90.16%, respectively, significantly higher than 63.93%, 80.33%, 77.05%, 65.57%, respectively in group A (P<0.05);the incidence of pressure ulcer in group B was 1.64%, significantly lower than 10.66% in group A (P<0.05). Conclusion CQI preventive care carried out in orthopedic surgery can improve the quality of care and PU prevention effect, reduce the incidence of acute PU, which should be applied widely.%目的：探讨持续质量改进(CQI)护理措施预防骨科大手术中形成急性压疮(PU)的效果。方法整群收集2012年1月-2014年1月该院骨科接受大手术治疗的患者244例，根据入院先后顺序分为A组与B组，各122例。 A组行传统护理措施，B组行CQI预防护理措施，比较两组的护理效果。结果B组术前压疮评估率、护理人员术中压疮知识知晓率、手术体位安置正确率以及手术医生对体位安置的满意率依次为97.54%、95.08%、93.44%、90.16%，均显著高于A组的63.93%、80.33%、77.05%、65.57%(P<0.05)；B组的压疮发生率为1.64%，显著低于A组的10.66%(P<0.05)。结论在骨科大手术中实施CQI预防护理有利于提高护理质量与PU预防效果，降低急性PU发生率，值得推广应用。
