Reliability Testing of Silverman-Andersen Retraction Score in Preterm Infants

February 13, 2020 updated by: St. Olavs Hospital
Depending on their gestational age, preterm infants need several weeks with different types of breathing-support due to immature development of the lungs, respiratory muscles, chest-wall and respiratory center in the brain. WHO's recommendation on interventions to improve preterm birth outcomes underline the need for more research on respiratory support in infants born preterm. This study will test inter-rater and intra-rater reliability of the Silverman-Andersen Retraction Score, which is a systematic clinical scoring tool for the respiratory work and the severity of respiratory distress in preterm infants. It will examine if there is consistency in the assessments done by doctors and nurses, and also if the observations correlate with technological monitoring. This easy to use scoring tool will help to determine the grade of respiratory distress, to assess respiratory exacerbation, to decide when to start weaning from respiratory support, and to give the best respiratory treatment to the child. This study will contribute to optimize care for preterm infants with respiratory distress.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

34-32 GA
premature infants born <34,6-32,1 weeks of gestational age (GA) receiving different types of non-invasive and invasive respiratory support, and severity of respiratory distress assessed by Silverman-Andersen Retraction Score.
Diagnostic test: Silverman-Andersen Retraction Score
The Silverman-Andersen Retraction Score (SAs) is used to assess severity of respiratory distress in newborn and preterm infants without respiratory support.The score comprises 4 inspiratory categories of movements (thoraco-abdominal, intercostal, xiphoid, and chin movements) and one expiratory category (grunting).
Other Names:
  • SAs
32-28 GA
premature infants born <32-28,1 weeks of gestational age (GA) receiving different types of non-invasive and invasive respiratory support, and severity of respiratory distress assessed by Silverman-Andersen Retraction Score.
