Intraoperative Extubation Post Arterial Switch Operation for Transposition of the Great Arteries With Intact Ventricular Septum: A One-Year, Single Center Experience.

We sought to examine the clinical impact of intraoperative extubation (IE) in neonates undergoing the arterial switch operation (ASO) for D-transposition of the great arteries with intact ventricular septum (dTGA/IVS). This was a single center retrospective study of patients who underwent ASO for dTGA/IVS in the 12 months after an institutional change in practice favoring IE when clinically feasible. A control group was obtained by identifying the same number of consecutive patients with dTGA/IVS who underwent ASO immediately prior to this institutional change in practice, none of whom were extubated intraoperatively. Primary outcome measures included morbidity, mortality, length of hospital and intensive care unit stay and reintubation rates. There were no significant differences in the preoperative and operative characteristics between the 2 groups. Of the 10 patients who underwent ASO for dTGA/IVS in the 12 months post institutional change in practice, all (100%) were extubated intraoperatively and none (0%) required reintubation. The median length of intensive care unit stay was 2 days for both the intraoperative and non-IE groups (mean 2.2 and 3 days respectively). The median length of stay in hospital was 4 days in the IE group and 5.5 days in the non-IE group (mean 4.5 and 6 days respectively). No patients died and there was no significant difference in morbidity between the 2 groups. Our data suggests IE post ASO for dTGA/IVS is safe and displays a statistically insignificant trend toward earlier discharge from hospital.
