Supportive care is the cornerstone of the poisoned patient’s treatment, waiting for eventual antidotes to act. We recently treated a case of a severe Ethylene Glycol intoxication with early-onset veno-arterial ECMO. The patient was taken to our Emergency Department with the suspicion of acute cerebrovascular accident, since he was found unconscious at home. The arterial blood gas and blood tests showed a severe metabolic acidosis with high serum lactates and creatinine levels. The cerebral Computed Tomography was negative. The rapid increase in serum lactates suggested Ethylene Glycol intoxication. Although the patient was not in shock yet, arterial and venous introducers were placed in to the femoral vessels so that when the patient showed the first signs of cardiogenic shock, veno-arterial ECMO could be initiated in a very short time. The hemodynamic state progressively improved and V-A ECMO was removed after 16 h of support with complete recovery.

Background: Antegrade root cardioplegia remains the most popular strategy for myocardial protection during coronary artery bypass graft (CABG) performed with cardiopulmonary bypass (CPB) and aortic cross clamp. In patients with depressed left ventricular function, however, especially if associated with severe multiple coronary stenosis, increased pharmacological and/or mechanical support in the early post-CPB period is often required to support left ventricular recovery. In this study, we analyzed the results of a myocardial protection strategy that includes selective infusion of cardioplegia through each venous graft followed by warm reperfusion distal to each coronary anastomosis until complete removal of the aortic clamp (total antegrade cardioplegia infusion and warm reperfusion = TAWR) to improve early postoperative recovery in patients with depressed left ventricular function undergoing multi-vessel CABG. Methods: Out of 97 patients undergoing CABG using the TAWR strategy for myocardial protection, 32 patients presented with depressed left ventricle function (EF < 40%) and multi-vessel coronary diseases requiring ≥2 vein grafts and were enrolled as Group A. Combined primary outcomes and postoperative early and late left ventricle recovery (including spontaneous rhythm recovery, inotropic support and postoperative troponin release) were analyzed and compared with those of 32 matched patients operated on using standard antegrade root cardioplegia and limited warm reperfusion through LIMA graft (SAWR) enrolled as Group B. Results: Two patient died in hospital (in-hospital mortality 3.1%) with no statistical differences between the two groups. In Group A 27 patients (90%) had spontaneous recovery of idiopathic rhythm compared to 17 (53%) in group B (p = 0.001). Early inotropic support was required in nine patients (28%) of group A and seventeen patients (53%) of group B (p = 0.041). Furthermore, in eight patients (25%) of group A and seventeen (53%) of group B (p = 0.039) inotropic support was continued for >48 h. Conclusions: The TAWR strategy seems to significantly improve early postoperative cardiac recovery in patients with left ventricle depression undergoing multi-vessel CABG, when compared with SAWR strategy and could therefore be considered the strategy of choice in this subset of patients.
