AbstractObjectivesWe aimed to investigate whether early postoperative extubation following the Fontan operation is universally feasible and can be used as a management tool in unstable patients.MethodsAll patients undergoing the Fontan operation in our centre between 2004 and 2013 (n=253) were analysed. Until 2008, patients were extubated according to standard criteria and comprised group 1. Group 2 included all patients presenting after 2009, when early extubation was always aimed regardless of the haemodynamic status. Patients who exceeded the 75th percentiles for volume requirements and inotrope scores for the respective group were defined as unstable. Comparisons of outcomes between groups and subgroups and analysis of the changes in haemodynamic and treatment parameters with extubation in unstable patients after 2009 were performed.ResultsCompared with group 1, patients from group 2 were ventilated for shorter duration (p<0.001), had similar re-intubation rates (p=0.50), and needed less volume (p=0.01). In group 2, the unstable patients were not ventilated for longer durations (p=0.19), but had higher re-intubation rates (p=0.03) than the stable patients. Compared with the unstable patients from group 1, the unstable patients from group 2 were ventilated for shorter duration (p<0.001), had similar re-intubation rates (p=0.66), and needed less volume (p=0.006). There was a significant acute and sustained increase in mean arterial pressure with extubation and a parallel reduction in volume requirements and inotrope scores in the unstable patients from group 2.ConclusionsTimely extubation is universally applicable following the Fontan operation. Early postoperative extubation can be valuable for improving Fontan haemodynamics.

Cavopulmonary Connection

Background—The total cavopulmonary connection (TCPC), a palliative correction for congenital defects of the right heart, is based on the corrective technique developed by Fontan and Baudet. Research into the TCPC has primarily focused on reducing power loss through the connection as a means to improve patient longevity and quality of life. The goal of our study is to investigate the efficacy of including a caval offset on the hemodynamics and, ultimately, power loss of a connection. As well, we will quantify the effect of vessel wall compliance on these factors and, in addition, the distribution of hepatic blood to the lungs. Methods—We employed a computational fluid dynamic model of blood flow in the TCPC that includes both the non-Newtonian shear thinning characteristics of blood and the nonlinear compliance of vessel tissue. Results—Power loss in the rigid-walled simulations decayed exponentially as caval offset increased. The compliant-walled results, however, showed that after an initial substantial decrease in power loss for offsets up to half the caval diameter, power loss increased slightly again. We also found only minimal mixing in both simulations of all offset models. Conclusions—The increase in power loss beyond an offset of half the caval diameter was due to an increase in the kinetic contribution. Reduced caval flow mixing, on the other hand, was due to the formation of a pressure head in the offset region which acts as a barrier to flow.
