ICU压疮发病特征及氧合作用和血流灌注指标与压疮发生的相关性研究

【目的】分析 ICU压疮发病特征及氧合作用和血流灌注指标与压疮发生的相关性。【方法】113例ICU患者分为压疮组（26例）与非压疮组（87例）。比较两组患者入院时的一般情况、氧合作用与血流灌注指标，并对有意义的指标进行进一步的 Logistic回归分析。【结果】压疮的多发部位为骶尾部、臀部及肩胛部，大多数压疮患者的分期为Ⅰ期或Ⅱ期；压疮组平均年龄及入院诊断为呼吸系统疾病与外伤患者的比例明显高于非压疮组（P＜0．05）；压疮组与非压疮组动脉血酸碱度（pH）、动脉二氧化碳分压（PaCO2）、收缩压（SBP）、舒张压（DBP）、平均动脉压（MAP）及Braden评分比较有统计学意义（P ＜0．05）；多因素分析结果显示高龄（β＝1．637，OR＝5．140）、呼吸系统疾病（β＝1．592，OR＝4．914）、外伤（β＝1．748，OR＝5．743）是 ICU患者发生压疮的危险因素，而高 MAP（β＝-1．528，OR＝0．217）、高Braden评分（β＝-1．705，OR＝0．182）是保护因素。【结论】高龄、呼吸系统疾病、外伤是 ICU患者发生压疮的危险因素，而高 MAP、高 Braden评分是保护因素。

Study on the Characteristics of Pressure Ulcer in ICU and the Correlation of the Occurrence with Oxygenation and Perfusion Index

Objective]To explore the characteristics of pressure ulcer in ICU and the correlation of the oc-currence with oxygenation with perfusion index.Methods]Totally 1 1 3 patients in ICU were divided into pressure ulcer group（n=26）and non-pressure ulcer group（n=87）.General information on admission,oxy-genation and perfusion index between two groups were compared.Meaningful indicators were taken for further logistic regression analysis to identify the correlation.Results]Multiple sites of pressure ulcer were sacrococ-cygeal region,hip and scapular.Most patients with pressure ulcer were divided into stageⅠ and Ⅱ.The av-erage age and the proportion of hospital admission diagnosis of respiratory disease and trauma in pressure ulcer group were obviously higher than those in non-pressure ulcer group（P〈0.05）.There were significant differ-ence in pH,PaCO2 ,SBP,DBP,MAP and Braden score between two groups（P〈0.05）.Multivariate analy-sis showed that the advanced age（β= 1.637,OR= 5.140）,respiratory diseases（β=1.592,OR=4.914）and trauma（β=1.748,OR=5.743）were risk factors for the occurrence of pressure ulcer in ICU patients,while high MAP（β=-1.528,OR=0.217）,high Braden score （β= -1.705,OR=0.182）were protective factors.Conclusion]The advanced age,respiratory diseases and trauma are risk factors for the occurrence of pressure ulcer in ICU patients,while high MAP and high Braden score are protective factors.
