Background: Cardiac output (CO) can be calculated noninvasively with Electrical Cardiometry (EC) utilizing thoracic electrical bioimpedance or minimal invasively with Transesophageal Doppler (TED). Aim was to compare EC to TED regarding (CO), ability to guided fluid administration and monitor haemodynamics during transplantation.

 Methods: 47 adult recipients (3 excluded): EC gp, (n = 22) and TED gp (n = 22). Following anaesthesia, TED probe was passed orally into mid-esophagus. Cardiometry skin sensors were applied simultaneously. In EC gp Anaesthetist were blinded to TED and vice versa. 6 ml/kg/h Ringer’s acetate, only 3 ml/kg Albumin 5% boluses when stroke volume variation (SVV) (%) in EC > 10% or corrected flow time (FTc) (msec) in TED < 350 msec. Rotational thromboelastometry guided blood products.

Results: Comparable age, weight, graft body weight ratio. An overall good degree of reliability between EC and TED CO, r = 0.928, 95% CI (0.913 - 0.941), p < 0.001. Median (IQR) EC CO was constantly higher than TED CO (l/min). After induction 7.55 [6.70 - 8.50] vs. 6.80 [6.10 - 7.50], p < 0.001, anhepatic: 7.60 [7.20 - 8.50] vs. 6.75 [6.35 - 7.50], p < 0.001, reperfusion: 7.90 [7.10 - 8.60] vs.7.25 [6.50 - 7.85] p < 0.001, end surgery 8.40 [8.00 - 8.80] vs.7.70 [7.25 - 8.20] p < 0.001, respectively. In EC vs. TED. 5500 [5200 - 6000] vs. 5525 [5200 - 6000] ml, p = 0.81 of Crystalloids and 800 [600 - 1000] vs. 850 [800 - 1000] ml, p = 0.2 of Albumin 5% were infused, respectively. FTc negatively correlated with SVV (t) = -0.321, p < 0.001, and both not in correlation with CVP.

Conclusion: The agreement between CO measured by EC and TED is acceptable. Both were able to monitor trend changes and guide fluid administration.
