Anaesthesia for non-cardiac surgery in children and young adults with Fontan physiology.

INTRODUCTION
Patients with Fontan physiology require non-cardiac surgery. Our objectives were to characterise perioperative outcomes of patients with Fontan physiology undergoing non-cardiac surgery and to identify characteristics which predict discharge on the same day.


MATERIALS AND METHOD
Children and young adults with Fontan physiology who underwent a non-cardiac surgery or an imaging study under anaesthesia between 2013 and 2019 at a single-centre academic children's hospital were reviewed in a retrospective observational study. Continuous variables were compared using the Wilcoxon rank sum test, and categorical variables were analysed using the Chi-square test or Fisher's exact test. Multivariable logistic regression analysis results are presented by adjusted odds ratios with 95% confidence intervals and p values.


RESULTS
182 patients underwent 344 non-cardiac procedures with anaesthesia. The median age was 11 years (IQR 5.2-18), 56.4% were male. General anaesthesia was administered in 289 (84%). 125 patients (36.3%) were discharged on the same day. On multivariable analysis, independent predictors that reduced the odds of same-day discharge included the chronic condition index (OR 0.91 per additional chronic condition, 95% CI 0.76-0.98, p = 0.022), undergoing a major surgical procedure (OR 0.17, 95% CI 0.05-0.64, p = 0.009), the use of intraoperative inotropes (OR 0.48, 95% CI 0.25-0.94, p = 0.031), and preoperative admission (OR = 0.24, 95% CI: 0.1-0.57, p = 0.001).


DISCUSSION
In a contemporary cohort of paediatric and young adults with Fontan physiology, 36.3% were able to be discharged on the same day of their non-cardiac procedure. Well selected patients with Fontan physiology can undergo anaesthesia without complications and be discharged same day.
