Comparison of Acute Airway/Respiratory Complications and Intervention Requirements in Extubations Performed During On-Hours Versus Off-Hours

Perioperative airway/respiratory complications are a major driver of morbidity and mortality. While UK audits NAP4 and NAP7 extensively examined major critical events (e.g., cardiac arrest), prospective standardized data on acute, more frequent extubation-phase complications-such as desaturation, laryngospasm, obstruction, bronchospasm, and aspiration-remain scarce. Off-hours procedures carry additional risks related to increased workload, reduced senior supervision, and clinician fatigue, though current evidence is inconclusive and requires further human-factors research using validated tools like the Karolinska Sleepiness Scale (KSS). This prospective cohort study at Kocaeli City Hospital aims to compare the incidence of acute airway/respiratory complications and intervention requirements during extubation and the first 30 minutes post-extubation between on-hours (08:00-16:00) and off-hours (\>16:00). Notably, this will be the first prospective observational study to specifically test NAP7's off-hours risk findings at the extubation stage, with the goal of strengthening patient safety and guiding institutional quality improvement.

Trial of Spontaneous Breathing Test

The hypothesis is that the Spontaneous Breathing Test (SBT) without pressure support (PS) is not inferior to the SBT with pressure support in relation to the following outcomes: a) extubation failure; b) time on MV. The main objective of this study is to determine whether SBT without PS is non-inferior to SBT with PS in relation to the primary outcome: a) extubation failure; and secondary outcomes: b) length of stay in the PICU and c) days free of MV. Pacients will be randomized to 2 arms: 1. SBT with PS 2. SBT without PS (with PEEP only)
