Comparison Between Swan-Ganz Catheter and Minimally Invasive Hemodynamic Monitoring During Liver Transplantation: Report of a Monocentric Case Series

The aim of the present investigation was to retrospectively evaluate the utilization of Swan-Ganz catheter during orthotopic liver transplantation as opposed to FloTrac/Vigileo in selected cases, comparing a number of clinical outcomes across postoperative hospitalization.Before 2015 all recipients received pulmonary artery catheter (Swan-Ganz group, n = 109). After 2015 Swan-Ganz was used only if coronary artery disease or high-grade portal hypertension or Child-Pugh C were present; the remaining recipients were assigned to FloTrac/Vigileo monitoring (Mini group, n =100). A number of clinical outcomes were considered.Donor's Risk Index was similar between groups (median value 1.7, P = .27). Anthropometric characteristics of the recipients were similar in the 2 groups. There were no significant differences in the proportion of patients with Child-Pugh C (P = .873), coronary artery disease (P = .18), and grade of portal hypertension (P = .733). The Model for End-Stage Liver Disease score was slightly higher in the Mini group: (9 [7-11] vs 9 [8-12], Swan-Ganz vs Mini, respectively, P .035). Swan-Ganz utilization decreased over time (92% vs 26%, Swan-Ganz vs Mini, P .001). Upon admission to the intensive care unit, patients of the Mini group presented a higher SAPS II score with similar values of Sequential Organ Failure Assessment score. Days on mechanical ventilation were similar between groups. The incidence of graft failure was similar between groups (2% vs 5%, Swan-Ganz and Mini group respectively, P = .376). Recipients' hospital length of stay was similar (13 days [11-19] vs 14 [11-20], P .083).Our data suggest that the intraoperative utilization of FloTrac/Vigileo for oncologic patients with low grade end stage liver disease is reasonably safe.
