Early extubation in tetralogy of Fallot patients after complete repair

AIM: To document the feasibility of early extubation and to know the effect of age, weight, and post-operative right ventricle/left ventricle ratio in early extubation in intracardiac repair for tetralogy of Fallot. MATERIALS AND METHODS: This is a prospective study of 76 consecutive patients undergoing intracardiac repair between January, 2010 and April, 2010. The patients were compared between duration of ventilation with age, weight, and post-operative left ventricle/right ventricle ratio. RESULTS: In the age group less than 10 years, 47 patients were extubated within 4 hours and 12 after 4 hours. In the age group of 10-20 years, eight patients were extubated within 4 hours and seven patients after 4 hours. In the more than 20 years category, one patient was extubated within 4 hours and the other after 4 hours. In the weight category less than 10 kilograms, 17 patients were extubated within 4 hours and seven patients after 4 hours. In the 10-20 kilogram category, 27 patients were extubated before 4 hours and four patients after 4 hours. In the more than 20-kilogram category, 12 patients were extubated before 4 hours and nine patients after 4 hours. Where the ratio was less than 0.5, 47 patients were extubated within 4 hours and 14 patients after 4 hours. Where the ratio was greater than 0.5, nine patients were extubated within 4 hours and six patients after 4 hours. CONCLUSION: There was no correlation between duration of ventilation with age, weight, and right ventricle/left ventricle ratio. Early extubation in patients after intracardiac repair in tetralogy of Fallot is safe and effective.
