外科术后患者发生压疮的危险因素分析

目的 分析外科术后患者发生压疮的危险因素，探讨有效的预防措施。方法对211例择期手术患者的一般资料，术前、术中和术后相关指标进行非条件Logistic回归分析。结果年龄、术前血红蛋白、淋巴细胞总数和术后首次下地时间是外科术后患者发生压疮的危险因素，OR值分别为0．950、0．952、0．288、1．021。结论术前的营养状况与术后压疮的发生密切相关，术前应对患者的营养状况进行全面评估，并进行有针对性的干预；术后在病情允许的前提下应鼓励患者尽早下地活动。

Risk Factors of Pressure Ulcers in Post-Operative Patients

Objective To analyze the risk factors of pressure ulcer in surgical patients after operation,so as to explore the feasible prevention measures.Methods Two hundred and eleven cases with selective operation were selected.Logistic regression analyses were used to analyze the patients' general data and pre-operative,intraoperative and post-operative indicators probable to induce pressure ulcer.Results Age,hemoglobin,lymphocyte and the first time up after surgery were significantly associated with the occurrence of pressure ulcers(odds ratio were 0.950,0.952,0.288,1.021,respectively).Conclusion The incidence of pressure ulcers is closely correlated with the preoperative nutrition status of patients.Nurses should evaluate the pre-operative nutrition status comprehensively,and then implement pertinent nursing interventions.The patients should be encouraged to move around earlier in reasonable conditions after operation.
