英文摘要 | The transcutaneous oxygen tension (TcPO2) and transcutaneous carbon dioxide tension (TcPCO2) were measured in a neonatal intensive care unit (NICU) to assess their reliability and accuracy in predicting arterial pressure of oxygen (PaO2) and carbon dioxide (PaCO2). Arterial blood gas was drawn for gas analysis and compared with TcPO2 and TcPCO2 using a transcutaneous monitor operated with an electrode temperature of 41℃. The electrode was attached to the skin of the chest after calibration, and recording was begun after stabilization. In total, 34 TcPO2/PaO2 and 35 TcPCO2/PaCO2 paired comparisons were obtained from 22 patients, including 12 term and 10 preterm infants. Eight patients required intubation with ventilation therapy. TcPO2 significantly differed from PaO2 (TcPO2=56.8±23.2 mmHg vs. PaO2=72.2±28.4 mmHg, mean±SD, p<0.001). TcPCO2 also significantly differed from PaCO2 (TcPCO2=52.9±14.0 mmHg vs. PaCO2=44.2±11.8 mmHg, p<0.001). The correlation coefficient in the TcPO2/PaO2 and TcPCO2/PaCO2 groups were 0.627 and 0.635, respectively. In conclusion, TcPO2 and TcPCO2 monitoring at 41℃ does not seem to be a reliable and accurate measurement for PaO2 and PaCO2 in neonates with a variety of illnesses. |
