effects of alprostadil on respiratory parameters and hemodynamics of newborns with persistent pulmonary hypertension

Objective: To investigate the effects of alprostadil on respiratory parameters and hemodynamics of newborns with persistent pulmonary hypertension. Methods: According to random data table method, 80 newborns of pulmonary hypertension were randomly divided into the control group (n=40) and observation group (n=40), patients in the control group were given normal frequency ventilation, on the basis of the treatment of the control group, the observation group received alprostadil. The changes of respiratory parameters and hemodynamics were compared between the two groups before and after treatment. Results: The levels of respiratory parameters (SaO 2 , PaO 2 , PaCO 2 ) and hemodynamics (PA, PVR, SVR) in the two groups before treatment were not statistically significant. After treatment, The levels of SaO 2 , PaO 2 in the two groups were significantly higher than those in the same group before treatment, and the observation group levels were (90.71±8.92)%, (85.27±8.23) mmHg, which were significantly higher than those in the control group after treatment; The levels of PaCO 2 , PA, PVR and SVR in the two groups after treatment were significantly lower than those in the same group before treatment, and the observation group were (35.22±3.46) mmHg, (26.95±3.78) mmHg, (725.71±108.82) dyns/cm 5 , (1 125.27±152.23) dyns/cm 5 , which were significantly lower than that of the control group. Conclusion: Adding alprostadil based on conventional frequent ventilation thraphy can effectively improve blood pressure and oxygen saturation, and improve hemodynamics of newborns with persistent pulmonary hypertension, which has important clinical value.
