Clinical observation on monitoring different body parts of neonatal intensive care unit critically ill newborns by percutaneous oxygen partial pressure and carbon dioxide partial pressure / 中国实用护理杂志

ABSTRACT

Objectives@#Study on the accuracy and influencing factors of neonatal intensive care unit (NICU) critically ill newborns different body parts monitoring by percutaneous oxygen partial pressure (TcpO2) and carbon dioxide partial pressure (TcpCO2), in order to provide a basis for non-invasive monitoring of critically ill newborns in ICU.@*Methods@#60 cases of critically ill newborns requiring blood gas analysis were selected as research cases during July 2017 to March 2018 in Wuxi City Maternity and Child Hospital Neonatology. According to the randomized control principle, three groups were divided, chest group (20 cases), abdomen group (20 cases), leg group (20 cases). The chest group placed the electrodes of the transcutaneous gas analyzer on newborns′ anterior chest. The abdomen group placed the electrodes on newborns′ abdomen. And the leg group placed the electrodes on the inner thigh. PaO2 and PaCO2 values were collected from the blood gas results of critically ill newborns. TcpO2 and TcpCO2 values were recorded. And at the same time, the electrode shedding situation was observed as well. Compare transcutaneous data and arterial blood data, and do analysis.@*Result@#The chest group TcpO2 (69.05±9.17) mmHg(1 mmHg=0.133 kPa), TcpCO2 (46.9±10.57) mmHg, PaO2 (76.4±8.64) mmHg, PaCO2 (40.65±4.74) mmHg, the PaO2 and PaCO2 values were obviously different from the blood gas analysis results (t=-2.608, 2.413, P<0.05). The abdomen group and the leg group had no significant differences (P>0.05) . And the electrode sheet shedding rate was 30% in the chest group, 25% in the abdomen group, and 10% in the leg group, the three groups had no significant differences (χ2=2.553, P>0.05) .@*Conclusion@#NICU critically ill newborns thigh skin monitoring by percutaneous oxygen partial pressure and carbon dioxide partial pressure has high accuracy, and the electrode sheet shedding rate is relatively low. Therefore, it is a safe and effective clinical monitoring method, of great significance for monitoring changes in the condition of critically ill newborns.
