Efficacy of Surfactant and Perinatal Risk Factors in NRDS With Different Gestational Ages

December 21, 2017 updated by: Li Wang, Daping Hospital and the Research Institute of Surgery of the Third Military Medical University

A Multicenter Clinical Study on the Comparison of the Efficacy of Surfactant and Perinatal Risk Factors in NRDS With Different Gestational Ages

Since exogenous surfactant replacement therapy was first used to prevent neonatal respiratory distress syndrome (NRDS)，it has become the main method of treatment of NRDS. However, in some infants, death is inevitable despite intensive care and surfactant replacement therapy, especially in near-term and term infants. The first goal of our study is to compare the therapeutic effect of pulmonary surfactant of infants at different gestational ages and to investigate whether exogenous surfactant replacement therapy is effective for all newborns with RDS. The second goal of our study is to further analyze the risk factors and causes of RDS in early preterm infants and near term/term infants.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

1 hour to 4 weeks (Child)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Probability Sample

Study Population

Infants with RDS who received surfactant therapy were recruited from 24 hospitals between January 2011 and December 2016.

Description

Inclusion Criteria:

Infants with RDS who received surfactant therapy were recruited between January 2011 and December 2016.

Exclusion Criteria:

Infants were excluded if they had any congeni- tal malformation, inherited metabolic abnormality, intrauterine infection, Rh/Rh incompatibility, pneumonia, pulmonary hypertension, meconium aspiration syndrome, or asphyxia.

early preterm infants with RDS
gestational age<34 weeks
Drug: Surfactant, Pulmonary，Curosurf
All NRDS were given an early endotracheal infusion of Curosuf, with an initial dose of 200mg/kg, and if the condition needed to be repeated. Compare the therapeutic effect of pulmonary surfactant of infants at different gestational ages and to investigate whether exogenous surfactant replacement therapy is effective for all newborns with RDS.
Other: Perinatal risk factors of NRDS
Compare the perinatal risk factors that were closely related to NRDS between early preterm infants with RDS and near term/term infants with RDS.
