Abstract:
Objective To analyze of the risk factors for persistent pulmonary hypertension of newborn(PPHN) after resuscitation in neonatal asphyxia.Methods Total 92 cases of PPHN in neonatal asphyxia were admitted in NICU,Beijing Children's Hospital Affiliated to Capital Medical University from Jan.2009 to Dec.2013 as PPHN group.According to patients condition,to case-control study method were randomly selected 92 cases without PPHN in neonatal asphyxia in the same period as control group.Except for other serious complications with PPHN,such as respiratory distress syndrome,meconium inhalation,pulmonary hemorrhage,neonatal severe pulmonary infection and diaphragmatic hernia.Apgar score and rescue measures after asphyxia based on the newborn perinatal questionnaire and body temperature,blood sugar,arterial blood gas and echocardiography on admission were recorded.Results Respiratory treatment of PPHN group and control group were 71 cases (77.2％) vs 28 cases (30.4％),respectively.There was significant difference (x2 =6.380,P =0.012).On admission,mean arterial pressure [(32.36 ± 11.52) mmHg],temperature [(34.3 ±0.28) ℃],blood sugar [(2.56 ±0.77) mmol/L] and arterial blood pH value (7.16 ±0.21) in PPHN group were lower than those of the control group [(38.55 ± 9.18) mmHg,(36.5 ± 0.71) ℃,(3.46 ± 0.53) mmol/L,7.21 ±0.14].For mild and severe asphyxia cases in the PPHN group,blood gas and pulmonary hypertension had no statistical difference after rescucitation in the delivery hospital.Conclusions Acidosis,hypothermia,low blood pressure and hypoglycaemia after resuscitation in neonatal asphyxia are major risk factors for genesis of PPHN.This research shows that rescue after asphyxia timely,early and respiratory support effectively,monitoring closely,treatment of hypoglycemia and hypothermia,correct acidosis and maintain blood pressure can play a positive role in decreasing the morbidity of PPHN in neonatal asphyxia.
