Abstract

Background: This section is under preparation and will be included in the next issue.

Objectives: In preterm or low birth weight infants, does gradual versus abrupt discontinuation of supplemental oxygen influence mortality, retinopathy of prematurity, lung function, growth or development?

Search strategy: The standard search strategy of the Cochrane Neonatal Review Group was used. This included searches of the Oxford Database of Perinatal trials, MEDLINE, previous reviews including cross references, abstracts, conferences and symposia proceedings, expert informants, journal handsearching mainly in the English language. An additional literature search of the MEDLINE, EMBASE, and CINAHL databases was conducted in order to locate any trials in addition to those provided by the Cochrane Controlled Trials Register (CENTRAL/CCTR).

Selection criteria: All trials utilising random or quasi-random patient allocation, in which gradual weaning was compared with abrupt discontinuation of supplemental oxygen in preterm or low birth weight infants, were eligible for inclusion.

Data collection and analysis: The methodological quality of the eligible trial was assessed independently by each author for the degree selection, performance, attrition and detection bias. Data were extracted and reviewed independently by the each author. Results were compared and differences resolved as required. Data analysis was conducted according to the standards of the Cochrane Neonatal Review Group.

Main results: The results of the one small trial of 51 infants included in this systematic review indicate a significant reduction in vascular retrolental fibroplasia (i.e. severe ROP) for infants weaned gradually from high oxygen concentrations compared with abrupt discontinuation (RR 0.22, 95% CI 0.07-0.68). This finding was independent of the duration of oxygen therapy.

Reviewer's conclusions: The results of this systematic review provide additional evidence linking routine exposure to high ambient oxygen in the early neonatal period to the development of ROP in preterm/LBW infants. However, due to small numbers and historical oxygen monitoring techniques, they provide little assistance to clinicians with regard to the most appropriate method of oxygen weaning, gradual or abrupt, in modern neonatal care settings.

The authors of this review are currently conducting a randomized, controlled trial of the effect of higher versus standard oxygen saturation targeting on long term growth and development of preterm infants.
