Association of time of day and extubation success in very lo
A Study was conducted to determine the association of overnight extubation (OE) with extubation success.

Retrospective cohort study was donee in three NICUs. Infants without congenital anomalies, less than 1500 grams at birth, who were ventilated and received an extubation attempt were included. Primary exposure was OE and outcome was extubation success defined as no mechanical ventilation for at least 7 days after extubation.

--A total of 76/379 infants received OE. Infants extubated during the daytime were older and had higher illness severity markers.

--Extubation success rates did not differ for overnight (75%) versus daytime extubations (76%) after adjusting for confounders.

Conclusively, though infants in this cohort undergoing daytime and OE were dissimilar, extubation success rates did not differ. Larger multicenter studies are needed to test these findings and identify markers of extubation readiness in preterm infants.
