[Retracted] Effects of Pulmonary Surfactant Combined with Noninvasive Positive Pressure Ventilation on KRT-14 and ET-1 Levels in Peripheral Blood and Therapeutic Effects in Neonates with Respiratory Distress Syndrome

Figure 1

Changes of blood gas indexes before and after treatment. (a) There was no significant difference in PaO₂ between the observation group () and the control group () (, ). PaO₂ in both groups was significantly increased after treatment (), and it in the observation group () was significantly higher than the control group () (, ). (b) There was no significant difference in PaCO₂ between the observation group () and the control group () (, ). PaCO₂ in both groups was significantly decreased after treatment (), and it in the observation group () was significantly lower than the control group () (, ). (b) There was no significant difference in PaO₂/FiO₂ between the observation group () and the control group () (, ). PaO₂/FiO₂ in both groups was significantly increased after treatment (), and it in the observation group () was significantly higher than the control group () (, ). denotes ; denotes .
