Introduction
The aim of this study is to compare the postoperative outcomes and early
mortality of peripheral and central cannulation techniques in cardiac
reoperations using propensity score matching analysis.
Methods
In this retrospective cohort, patients who underwent cardiac reoperations
with median resternotomy were analyzed in terms of propensity score
matching. Between November 2010 and September 2020, 257 patients underwent
cardiac reoperations via central (Group 1) or peripheral (Group 2)
cannulation. A 1:1 propensity score matching was performed to balance the
influence of potential confounding factors to compare postoperative data and
mortality rate.
Results
There were no significant differences when comparing the matched groups
regarding early mortality (P=0.51), major cardiac injury (P=0.99), prolonged
ventilation (P=0.16), and postoperative stroke (P=0.99). The development of
acute renal failure (P=0.02) was statistically less frequent in Group 1.
Conclusions
Performing cardiopulmonary bypass via peripheral cannulation increases acute
renal failure in cardiac reoperations. In contrast, peripheral or central
cannulation have similar early mortality rate in cardiac reoperations.
