Abstract:
Objective:To investigate the early warning value of transcutaneous oxygen pressure and transcutaneous carbon dioxide pressure (TcPO 2/TcPCO 2) monitoring in patients with pressure injury in ICU. Methods:A prospective clinical observation study was conducted. Patients were selected in the department of critical care medicine of Shenzhen Hospital Affiliated to University of Chinese Academy of Sciences from December 2020 to June 2022. The general information of all patients were recorded. The data of TcPO 2 and TcPCO 2 were monitored respectively in left lying position, supine position and right lying position. According to the Braden score of patients, they were divided into low risk group and high risk group, and the monitoring results of TcPO 2/TcPCO 2 were analyzed. Results:The study included a total of 80 patients, with 46 patients in the low risk group and 34 patients in the high risk group. There were no significant differences in gender and age between the two groups (both P>0.05). There were significant differences in the Braden score and the incidence of pressure injury between the two groups (both P<0.05). There were statistically significant differences in TcPO 2 at various time points in the left lying position, supine position and right lying position between the low risk and the high risk groups (all P<0.001). Except for the 15th minute of the left lying position and right lying position, there were statistically significant differences in TcPCO2 at all other time points in the supine and right lying positions between two groups (all P<0.05). There were statistically significant differences in TcPO 2/TcPCO 2 values at various time points in different positions between two groups (all P<0.001). In supine position, TcPO 2 and TcPO 2/TcPCO 2 were positively correlated with the Braden score ( r=0.680, 0.741). TcPCO 2 was negatively correlated with the Braden score ( r=-0.771). The Braden score, TcPO 2, TcPCO 2 and TcPO 2/TcPCO 2 all have moderate diagnostic value. The cut-off values were 12.50, 41.48 mmHg, 52.29 mmHg and 0.91, respectively. And the AUC were 0.899, 0.727, 0.816 and 0.719, respectively. However, there were no significant differences in AUC between the TcPO 2, TcPCO 2, TcPO 2/TcPCO 2 and Braden score (all P>0.05). Conclusions:TcPO 2, TcPCO 2 and TcPO 2/TcPCO 2 values all have higher diagnostic value about pressure injury for patients in ICU. TcPO 2/TcPCO 2 monitoring has early risk warning value for the occurrence of pressure injury in ICU, which is worthy of clinical promotion.
