Abstract
Background/Aim: Effective lung isolation is required in minimally invasive cardiac surgery. Double
lumen tubes (DLT) are most preferred for this type of operation, and data on the use of EZ blockers in
cardiac surgery are limited. We aimed to compare the efficiency of the double lumen tube and EZ blockers
in minimally invasive cardiac surgery with cardiopulmonary bypass performed through a right mini
thoracotomy.
Methods: A total of 89 patients who underwent minimally invasive cardiac surgery through right mini
thoracotomy with cardiopulmonary bypass between January 1 and December 31, 2020, were included in
this single-center, retrospective case control study. The group in which double lumen tubes were used for
lung isolation (n = 58) was compared with that in which EZ blockers (n = 31) were used in terms of
placement time, repositioning rate, lung collapse quality score, and postoperative sore throat and
hoarseness.
Results: The time needed to place the devices in the correct position was shorter in the DLT group (3.2
(2.7) min vs 4.6 (2.4) min, P=0.02). No significant difference was found between the prevalence of at least
one repositioning and lung collapse quality scores (P=0.42, P=0.21). VAS scores for sore throat were
lower and hoarseness was less encountered in the EZ blocker group (21.2 (8.8) vs 49.4 (7.6), P=0.01,
16.1% vs 48.2%, P=0.01, respectively).
Conclusion: Although the EZ blocker has a longer placement time, it provides lung isolation as effective
as DLT. Less sore throat and hoarseness show that EZ blocker is an important alternative for this type of
surgery.
