Assessment

Primary outcomes

The primary outcome is the incidences of PPCs within 48 hours after extubation. PPCs are defined as the combination of atelectasis diagnosed by chest radiography and acute respiratory failure.

Radiologist measures atelectasis by chest radiography at 1 and 2 postextubation days.

Investigator diagnoses ARF at 1 and 2 postextubation day.
Definition of respiratory failure
1 Increased respiratory rate (RR) for their age+The use of accessory respiratory muscle
RR>50 breath per minute (<1 year old)
RR>40 breath per minute (1-4 years ol0
2 Hypoxemic acute respiratory failure (type 1)
PaO2<60 mmHg
SaO2<90% (with FiO2>0.5)
3 Hypercapnic acute respiratory failure (type 2)
pH<7.35 with PaCO2>50 mmHg
4 Mix form of acute respiratory failure

Prophylactic use of HFNC therapy might have the potential to reduce the incidence of PPCs following extubation after pediatric cardiac surgery. To investigate this hypothesis, we set PPCs incidence less than 10% as a threshold of a effectiveness of prophylactic HFNC therapy on the basis of the reintubation rate in children underwent cardiac surgery in previous reports (6 to 9%)

Key secondary outcomes

Reintubation less than 48hours
Completion rate of 24-hours HFNC therapy
Length of ICU stay
PaO2 / FiO2 (post-extubation periods)
High-flow nasal cannula related adverse events

Interventions/Control_1

HFNC (Optiflow; Fisher and Paykel Healthcare Ltd, Auckland, New Zealand) therapy is prophylactically commenced just after extubation with 2L / kg / min of flow, 37 degrees of temperature with humidifier and adequate fraction of inspiratory oxygen (FIO2) to achieve target oxygen saturation >94%. We choose nasal cannula size according to child's weight and nasal size. HFNC will be continued for 24-hours after extubation if intolerance does not occurred.
If patients are not tolerant to HFNC treatment with flow of 2L / kg / min, we reduce flow rate of HFNC to 1 L /kg /min. If intolerance occurred in flow rate of 1L / kg / min, we reduce flow rate of HFNC to less than 1 L /kg /min or change HFNC therapy to conventional oxygen therapy such as facemask and nasal cannula. There is no limitation of oxygen therapy after 24-hours of intervention periods.
