Abstract:
A total of 60 infants with severe persistent pulmonary hypertension (PPHN) at our NICU from January 2006 to December 2012 were divided into research group[(n =32,high-frequency oscillatory ventilation(HFOV) plus sildenafil)]and control group (n =28,HFOV only).Mean pulmonary arterial pulmonary arterial (MPAP),blood gas analysis,oxygenation index (OI),PO2 to fraction of inspired oxygen ratio (PO2/FiO2) before and after treatment were compared between two groups.After 3-day treatment,MPAP (mm Hg)(32 ±6) vs.(43 ±9)mm Hg,PCO2(mm Hg)(36 ±9) vs.(43 ±9),OI(56 ±22) vs.(85 ±21) in research group were significantly lower than those in control group(P ＜ 0.05) ; in comparison with control group,PO2(mm Hg) (89 ±15) vs.(72 ±22),PO2/FiO2(mm Hg) (223 ± 18) vs.(196 ±24) in research group were significantly higher(P ＜ 0.05).The time of ventilation use (d) (5.4 ± 1.3) vs.(6.3 ± 1.6) in research group was shorter than that of control group(P ＜0.05) while research group showed a higher clinical efficiency rate(％) (81.2 vs.50.0) (P ＜0.05).A combination of HFOV and sildenafil for severe PPHN can significantly reduce MPAP,shorten the duration of ventilation use and improve cure rate.
