Procedure: Intubate-Surfactant-Extubate(INSURE)
Procedure: less invasive surfactant administration(LISA)
Registration Number

Anhui Provincial Hospital
Brief Summary

To evaluate the efficacy of less invasive surfactant administration(LISA )technique in the treatment of neonatal respiratory distress syndrome(NRDS) by comparing with the traditional Intubate-Surfactant-Extubate(INSURE) technique.

Detailed Description

Background: Neonatal Respiratory distress syndrome (NRDS) is the most common cause of respiratory problems in premature babies. Surfactant administration involved with endotracheal intubation and mechanical ventilation has proven to be a effective treatment, however, it is associated with a risk of barotrauma, volutrauma and bronchopulmonary dysplasia(BPD). In recent years, some studies have demonstrated that prophylactic INSURE did not lead to a higher survival without BPD, and LISA technique is recommended. However there is no multicenter and Large sample research about it. The aim of this multicenter trial is to compare the efficacy between LISA-treated and INSURE-treated premature Preterm babies with respiratory distress syndrome(RDS).

Methods/Design:In this multicenter, randomized, cohort, prospective trial, 200 preterm infants from 18 neonatal intensive care units in AnHui province whose gestational age (GA) less than 32 weeks with a diagnosis of RDS will be randomized to LISA-treated group and INSURE-treated group.

The primary outcomes include rate of intubation,incidence of bronchopulmonary dysplasia(BPD).The secondary outcomes include arterial blood gas analysis,severity of RDS,the incidence of Patent ductus arteriosus(PDA),Pneumothorax,Abdominal Distention,Neonatal Necrotizing Enterocolitis(NEC,\>Stage II), Retinopathy of Prematurity( ROP,≥ Stage II), Intraventricular Hemorrhage (IVH, ≥ Grade Ⅲ), Periventricular Leukomalacia(PVL) , mortality, days on noninvasive respiratory support,days on supplemental oxygen and days of hospitalization.Other secondary outcomes include scores of Gesell development Scales of infant development at 3 years of corrected age.

Primary Outcome Measures
NameTimeMethod
The incidence of bronchopulmonary dysplasiaat a post-menstrual age of 36 weeks or at discharge

BPD was diagnosed and classified based on the Practical neonatology 4th edition:Need for O2 supplementation(FiO2\>0.21) for at least 28 days after birth.

Rate of intubationduring the first 3 days after birth

The criteria for endotracheal mechanical ventilation were as follows: severe apnea and bradycardia (defined as recurrent apnea with \> 3 episodes per hour associated with heart rate \< 100/min, a single episode of apnea that required bag and mask ventilation), hypoxia (FiO2\>0.6 with PaO2\<50mmHg or TcSO\<0.85), severe respiratory acidosis (PaCO2 \> 60 mmHg with pH\<7.20).
