Abstract:
Objective To discuss the relationship between the clinical pathogenesis and progression in neonatal pulmonary hypertension in different stages.Methods Total 169 cases of pulmonary hypertension were admitted in our NICU from June 2006 to May 2012,all the cases were involved in this retrospective study.They were divided into two groups in chronological order:early group 79 cases (from June 2006 to May 2009) and late group 90 cases (from June 2009 to May 2012).The data records include gender,gestational age,protopathy,echocardiography examination results.Furthermore,the cause and development of neonatal pulmonary hypertension were analyzed in different stages.Results The admission time in the early group was later than the late group [(2.15 ± 1.2) d vs (1.41 ±0.70) d].Meconium aspiration syndrome in the early group were 25 cases (31.6％) and the late group were 14 cases (15.6％).Other complications,such as congenital diaphragmatic hernia,neonatal respiratory distress syndrome,aspiration pneumonia,wet lung/sepsis,neonatal asphyxia,neonatal infectious pneumonia had no difference between the two groups(P ＞0.05).Neonatal pulmonary hypertension in two groups had no statistical difference between term and post term patients,but premature in the early group (11 cases,13.9％) were less than the late group (23 cases,25.6％).Echocardiography was recorded after admission,mild and moderate pulmonary hypertension had no statistical differences in the two groups (P ＞ 0.05).The severe pulmonary hypertension cases in the early group were more than those in the late group (26 cases vs 17 cases).Conclusion Along with the improvement of perinatal monitoring and resuscitation technology in different stages,the cases of meconium aspiration syndrome with pulmonary hypertension are fallen down and the patients transferred to the superior hospital decreased.The amount of pulmonary hypertension in preterm infants increases,and the admission time of patients with neonatal pulmonary hypertension are shortened.The amount of severe pulmonary hypertension are less than those in the early time.It plays a positive role in best approach to improving treatment and outcomes.
