Aim:
To identify risk factors associated with the failure of extubation of mechanically ventilated very-low-birth-weight newborns.
Study Design:
Prospective observational study. Assessment of the occurrence of extubation failure in relation to demographic and ventilation parameters, the SpO2/FiO2 ratio, the spontaneous breathing test (SBT) and values of the Silverman-Andersen score (SAS). Extubation failure was defined as the need for reintubation for any reason within 72 h after extubation.
Results:
Extubation failed in 14/50 (28%) patients. Tidal volume applied at the moment of extubation (p = 0.030), the values of the SpO2/FiO2 ratio (p = 0.006), SBT (p = 0.034) and SAS measured for 60 min after extubation and later (p = 0.010, p = 0.000001, p∼0.000, respectively) showed a significant association with reintubation.
Conclusions:
Measured TV, SpO2/FiO2 ratio, SBT at the moment of extubation and values of SAS starting 1 h after extubation might be valuable parameters in identifying those VLBW newborns in the risk to fail extubation.

Endotracheal Tube Extubation
Procedure
Extubation removes the endotracheal tube (ETT) from the patient on mechanical ventilation. It requires a well-coordinated, multidisciplinary approach involving physicians, nurses, respiratory therapists, and other healthcare professionals....

Acute Respiratory Failure-I
Definition: It is defined by specific criteria based on blood gas measurements. Hypoxemia happens when the partial pressure of oxygen (PaO2) falls below 60 mmHg. At the same time,...
