Clinical Variables Specific to Timing of Tracheal Extubation Following Pediatric Cardiac Surgery

Area of Science:

• Pediatric Cardiac Surgery
• Anesthesiology
• Intensive Care Medicine

Background:

• Tracheal extubation timing in pediatric cardiac surgery is critical for patient outcomes.
• This study investigates factors influencing extubation on the operating table, within 6 hours, or after 6 hours post-operatively.
• Chromosomal disorders and arterial blood gas parameters were also assessed.

Purpose of the Study:

• To identify specific factors associated with early tracheal extubation in pediatric cardiac surgical patients.
• To compare extubation timing strategies: on the operating table, within 6 hours, or after 6 hours post-operatively.
• To evaluate predictors of failed extubation and intensive care unit (ICU) stay duration.

Main Methods:

• Patients were categorized into three groups based on extubation time: operating table (Group I), within 6 hours (Group II), and after 6 hours (Group III).
• Groups I and II were combined as a "fast-track" extubation group.
• Demographic data, Risk Adjustment for Congenital Heart Surgery (RACHS-1) score, STAT Mortality Category, cardiopulmonary bypass (CPB) time, aortic cross-clamp (ACC) time, and vasoactive-inotropic score (VIS) were recorded.

Main Results:

• Bivariate analysis revealed associations between age, weight, RACHS-1, STAT category, CPB time, ACC time, and VIS with operating table and fast-track extubation.
• Multivariate analysis identified weight, lower STAT category, CPB time, and VIS as independent predictors for operating table and fast-track extubation.

Conclusions:

• Younger age, lower weight, higher RACHS-1, STAT category, and VIS, along with longer CPB and ACC times, are associated with delayed tracheal extubation.
• Optimizing these factors may facilitate earlier extubation and potentially improve outcomes in pediatric cardiac surgical patients.
