Abstract
There is little known about the time of the day and the nature of it (business day/non-business day) at which extubation is performed, and whether it is safe during the night.
Objective: to describe the frequency of nocturnal extubation (NE) and non-business day extubation (nBDE). In addition, to determine the association between these and clinical outcomes.
Patients and Method: Retrospective cohort study of patients under 18 years of age who received invasive mechanical ventilation (MV) and underwent an extubation attempt in a high complexity Pediatric Critical Patient Unit (PCPU) between 01/01/2018 to 12/31/2021. Primary exposure: NE, which was defined as that performed between 20:01 and 8:00 hours. Its association with extubation failure (EF), duration of invasive MV, and length of stay in the PCPU was evaluated.
Results: 146 patients were included [58.9% males, age 1.14 (0.25 - 5.5) years]. NE was performed in 17.8%. Nocturnal extubation was not associated with EF nor was the day of extubation. The EF was 3.8% in NE and 5% in daytime extubation (DE) (p = 0.80). Duration of invasive MV was shorter in NE than DE [48 (24-73.5) vs. 72 (48-96) h, p = 0.02].
Conclusions: NE was not associated with EF. Patients with NE had shorter duration of invasive MV, and the latter was associated with EF. Withdrawal of invasive MV should be considered at the first opportunity and be determined by clinical factors, rather than time of day.
