Abstract
Objective:
To characterize clinical outcomes of infants born after previable rupture of membranes (pROM, < 23 weeks gestation and latency period ≥ 2 weeks) in relation to refractory hypoxic respiratory failure (rHRF).
Study Design:
pROM neonates categorized as rHRF (FiO2 > 0.6 for ≥ 2 h) and treated (high frequency ventilation + inhaled nitric oxide) were compared with no rHRF group. Primary outcome was survival until discharge. Factors associated with rHRF and mortality were identified.
Result:
Overall, mortality and disability rates were 28% and 22%, respectively. Treated rHRF group (n = 32) had longer period of ROM, mortality was (31% vs. 14%; p = 0.20), with similar survival-without-disability (54% vs. 47%; p = 0.67). Higher gestational age at birth [1.57 (1.03,2.39)] and cesarean delivery [12.6 (1.22,125)] were associated with increased survival.
Conclusion:
Birth after pROM is associated with high rates of adverse outcomes, independent of latency period. Following treatment, rHRF infants may have similar long-term outcomes as those without rHRF.
