Brief Summary

Weaning from mechanical ventilation post congenital cardiac surgery is often challenging. It is well known that not all patients can be early extubated, although most are suitable for early postoperative weaning and extubating despite complex operative procedures. With advances in anaesthesia management, cardiopulmonary bypass (CPB), and surgical techniques, the trend of 'fast tracking', and early extubating of pediatrics postcardiac surgery seems to be feasible. Unnecessary prolonged mechanical ventilation increases the complication risks as airway trauma, ventilator associated pneumonia, and increased hospital stay

Conditions

Weaning Mechanical Ventilation; Pediatric Cardiac Surgery

Keywords

automatic tube compensation; congenital cardiac anomalies

Outcome Measures

Primary Outcomes (1)

• work of breathing (WOB)

  Compare the efficacy of ATC versus PS as a modality for ventilatory weaning of paediatric post-cardiac surgery as regards effects on ventilator-derived work of breathing (WOB) (J/L).

  during weaning trial 30 minutes

Secondary Outcomes (4)

• lung compliance

  during ventilatory weaning in 30 minutes

• Numbers of weaning trials.

  48 hour post operative

• recording the requirement for reintubation and mechanical ventilation

  within 48 hours after extubation

• alveolar recruitment

  base line immediately before starting weaning trial, every 15 minutes during the weaning trial and 15 minutes after extubating

• Age Groups: Child (0-17)

You may qualify if:

• Age 2-10years.
• Both sex.
• after fulfilling weaning criteria
• being pain free (observational pain/discomfort scale \< 4). the weaning criteria; which include: low mandatory ventilator rate \[6-8\] or less; fraction of inspired oxygen (FIO2) ≤ 40; level of positive end expiratory pressure (PEEP) \[3-5 cmH2O\] guided by pressure/volume loop; reversal of the cause of postoperative mechanical ventilation; oxygenation index (OI) (mean air way pressure × FIO2/PaO2) \< 5; dynamic compliance (Cdyn) \> 1 ml/ cmH2O/kg
