老年人压疮临床相关影响因素初探

目的研究个体化综合方案治疗老年人压疮疗效的相关影响因素。方法选取2014年3月至2016年12月期间，应用个性化综合治疗方案对99例老年Ⅳ期压疮患者进行治疗，通过创床局部组织氧饱和度（rSO_2）等方法，对疗效进行比较分析。结果影响愈合主要危险因素有低蛋白血症、血细菌培养阳性、心肺功能障碍和周围血管血运障碍，且心肺功能障碍和周围血管血运障碍具有较高的特异性和阳性预测值；rSO_2检测数据显著提升组的患者与其创面愈合率呈正相关。结论血细菌培养阳性、心肺功能障碍、周围血管血运障碍、低蛋白血症是导致治疗老年人压疮失败率增高的危险因素。同时压疮创床rSO_2检测可作为临床疗效预估的参考指标。

Objective To study the related factors of individualized comprehensive program in the treatment of elderly patients with pressure sores. Methods 99 cases of elderly patients （ Ⅳ pressure sores ） were applied to individualized comprehensive treatment between March 2014 and December 2016, and the curative effect was compared and analyzed by means of local tissue oxygen saturation （ rSO_2 ） . Results The main risk factors for wound healing were hypoproteinemia, positive blood culture, cardiopulmonary dysfunction and peripheral vascular dysfunction. It also had high specificity and positive predictive value for cardiopulmonary dysfunction and peripheral vascular dysfunction. There was a positive correlation between the rSO_2 detection data and the wound healing rate. Conclusion Positive blood bacteria culture, cardiopulmonary insufficiency, peripheral blood vessel obstruction, and hypoproteinemia are the risk factors for the increased failure rate of senile pressure sore. And the rSO_2 test of the pressure sore can be used as a reference index for the prediction of clinical efficacy.
