Strategies for managing transient tachypnoea of the newborn - a systematic review.

OBJECTIVE: To conduct a systematic review of strategies for the management of transient tachypnoea of the newborn (TTN).

METHODS: The Cochrane Collaboration and PRISMA guidelines were used for conducting and reporting this systematic review, respectively. The Cochrane Central Register of Controlled Trials, PubMed, CINAHL and EMBASE databases were searched in February 2016. Only randomised and quasi-randomised controlled trials (RCTs) assessing any intervention for the management of TTN in infants <7 days of age, born at 35 or more weeks with a clinical diagnosis of TTN were eligible for inclusion. Primary outcomes included the duration of respiratory support, oxygen support, tachypnoea and hospitalisation.

RESULTS: Nine RCTs with moderate risk of bias were included. The interventions assessed included furosemide (2 trials, n = 100), inhaled salbutamol (2 trials, n = 94), inhaled epinephrine (1 trial, n = 20), restrictive fluids (2 trials, n = 146) and non-invasive ventilation (2 trials, n = 80). Amongst all interventions, inhaled salbutamol significantly reduced the duration of hospitalisation (2 trials, n = 94) [mean difference (MD) - 1.63 days (95% CI -2.71 to -0.55); p = 0.003] and duration of oxygen requirement (1 trial, n = 37) [MD - 43.10 h (95% CI -81.82 to -4.38; p = 0.03] without adverse effects.

CONCLUSION: Limited low-quality evidence exists on the effects of different management strategies for TTN. The safety and efficacy of inhaled salbutamol in the treatment of TTN can be assessed in a large RCT.
