老年人实时体表压力分布与经皮组织氧分压监测临床意义

Clinical effect on monitoring of real-time interface pressure distribution and transcutaneous partial pressure of oxygen in the elderly patients

目的探讨人体实时压力分布与压疮易患部位皮肤微循环的关系。方法选取入院符合准入老年患者54例,通过Braden评分分组后测定各部位经皮氧分压;通过建立可视压力分布平台,间隔2h实时测定体表平均压力和骶尾部经皮氧分压。结果 Braden评分各组中肩部和髋部在不同分组中的经皮氧分压差异无统计学意义(P>0.05),但是各组骶尾部经皮氧分压差异有统计学意义(P<0.05);间隔2h后的骶尾部平均压力变化无显著性差异(P>0.05),而经皮氧分压则有显著性差异(P<0.05)。结论老年人压疮易患部位皮肤微循环改变与其发生压疮风险有一定关联性,加强压疮易患部位实时体表压力监测和经皮氧分压测定为临床早期干预提供客观依据,有助于降低压疮发生率。

Objective To investigate the relationship between real-time interface pressure distribution and skin microcirculation in prone areas of pressure ulcer. Methods 54 elderly patients admitted to hospital were selected and divided into three groups by Braden score. Transcutaneous partial pressure of oxygen (tcPO2) were measured in the shoulder, hip and sacrococcyx, and the mean body surface pressure of the sacrococcyx were measured in realtime by establishing visual pressure distribution platform. Real-time measurement of mean body surface pressure and transcutaneous partial pressure of oxygen were measured in the sacrococcyx at intervals of 2 hours. Results There was no significant difference in the tcPO2 between shoulder and hip in different groups (P>0.05), but there was significant difference in the sacrococcyx of each group (P<0.05), and the mean body interface pressure of sacrococcyx after 2 hours was no significantly different in each group (P>0.05), and the tcPO2 of sacrococcyx after 2 hours was significantly different in each group (P<0.05). Conclusion The changes of skin microcirculation and the body interface pressure are related to the risk of pressure ulcer, and the real-time body interface pressure monitoring and the tcPO2 measurement in the elderly patients might help to provide basis for the early intervention and to reduce the incidence of pressure ulcer.
