Abstract:
Objective To analyze the relevant factors of early warning in emergency patients with high risk of acute sores, explore the application value of transcutaneous oxygen pressure(TcPO2) and transcutaneous carbon dioxide pressure(TcPCO2)monitoring in the early warning of emergency patients with pressure ulcers. Methods This was a study of 186 consecutive emergency patients who were under care in the emergency department. The transcutaneous oxygen/carbon dioxide pressure monitor was used in monitoring the oxygen saturation of the skin of sacrococcygeal region and the chest. Meanwhile,the Braden scale was used in assessing risk factors for pressure ulcers and the receiver operating characteristic curve (ROC curve) was applied to evaluate the early prediction of pressure sore with TcPO 2/TcPCO2 monitor. Results Implementing the logistic regression model with six indicators, this research concluded that TcPO2 CV and PO2 were independent risk factors for the development of Braden scale in patients with high risk. The area under the ROC curve showed that TcPO2 CV had a excellent predictive value for the high-risk group and determined its cut-off value to be 20％. Which means patient with both a value of TcPO2CV over 20％ and a high risk of Braden scale had a larger possibility of pressure ulcers. Conclusions TcPO2 CV was an independent risk factor for patients under emergency care to develop pressure ulcers. A value of TcPO2CV over 20％indicated a high risk of pressure ulcers.
