Outcome of tracheostomy after pediatric cardiac surgery.

OBJECTIVE: To investigate the incidence, timing indications and outcome of tracheotomy in children who underwent cardiac surgeries.

METHODS: All pediatric cardiac patients (under 14 years of age) who underwent cardiac surgeries and required tracheotomy from November 2000 to November 2010 were reviewed. The data were collected and reviewed retrospectively.

RESULTS: Sixteen children underwent tracheotomy after cardiac surgery. Fifteen of these cases had surgery for congenital heart disease, and one had surgery for an acquired rheumatic mitral valve disease. The mean ± SEMs of the durations of ventilation before and after tracheotomy were 60.4 ± 9.8 and 14.5 ± 4.79 days respectively (P value 0.0002). The means ± SEM of the lengths of ICU stay before and after tracheotomy were 63.31 ± 10.15 and 22 ± 5.4 days respectively (P value 0.0012). After the tracheotomy 12/16 patients (75%) were weaned from their ventilators and 10/16 were discharged from the PCICU. Six patients were discharged from the hospital and 3 were successfully decannulated. The overall survival rate was 9/16 (56%).

CONCLUSION: Tracheostomy shortens the duration of mechanical ventilation and facilitates discharge from the ICU. The mortality of tracheotomy patients is still significant but is mainly related to the primary cardiac disease.
