Analysis of Efficacy of Hyaline Membrane Disease of Newborn Treated with Pulmonary Surfactant by Endotracheal Instillation

Abstract

Objective To study the efficacy and safety of pulmonary surfactant used in hyaline membrane disease(HMD)of newborn treatment.Methods 67 cases of HMD children were treated.And pulmonary surfactant was used by intratracheal instillation.Clinical manifestation,blood gas analysis,X-ray chest film and complication before and after treatment were observed and recorded.Results 65 cases of children were recovered and discharged(97.01％),while 2 cases were dead.The PO2 increased significantly after the surfactant was given(P＜0.05),while the PCO2 decreased significantly(P＜0.05),and situation of skin cyanosis was relieved.X-ray chest films in 24 hours showed that 62 cases were improved(92.54％),while 4 cases were not obvious(5.97％),and there was hemorrhage image in the last 1 caes(1.49％).There were 5 cases of complication,involving 3 cases of pneumonia,1 case of intracranial hemorrhage and 1 case of pulmonary hemorrhage.Conclusion Clinical symptoms could be impurved rapidly,pulmonary oxygenation could be ameliorated,the need of mechanical ventilation could be lower and the rate of incidence of complication and death could be reduced effectively by using pulmonary surfactant early.
