- Design
- Systematic review and meta-analysis of 17 randomised trials
- Population
- 1,317 near- and full-term infants with transient tachypnea of the newborn
- Primary outcome
- Durations of respiratory support, tachypnea and hospital stay
- Effect
- Respiratory support −14.85 h (−25.05 to −4.65); tachypnea no change (−9.93 h, −25.42 to 5.56)
Transient tachypnea of the newborn is common and self-limiting, but tempting to treat. This meta-analysis pooled 17 randomised trials (1,317 infants) of nebulised salbutamol for it.
Salbutamol was associated with shorter durations of respiratory support (mean 14.9 hours less), CPAP, oxygen and hospital stay. But it did not shorten the tachypnea itself (mean −9.9 hours, 95% CI −25.4 to +5.6) or the NICU stay, and the certainty of all the evidence was rated low to very low. The apparent benefits on support duration sit alongside no effect on the defining symptom.
The honest reading is that this is not a basis for routine salbutamol in transient tachypnea. Supportive care remains the treatment; if salbutamol is trialled in a more severe case, it should be as a considered exception, not a default, and stopped if it is not clearly helping.
- Salbutamol was linked to shorter respiratory support, oxygen and hospital stay in transient tachypnea.
- It did not shorten the tachypnea itself or the NICU stay.
- The certainty of all outcomes was low to very low.
- Keep supportive care as standard; do not adopt salbutamol routinely.
Why it matters
It checks an intuitively appealing treatment before it becomes habit on weak evidence.
Don't overread it
Significant reductions in support duration on low-certainty evidence, with no effect on the tachypnea itself, do not establish that salbutamol works.
The statistics, in plain English
A statistically significant result on a secondary duration can still be unreliable when the certainty is graded very low and the defining outcome — the tachypnea — does not move; that pattern argues against a real treatment effect.
