ECMO POST-CARDIOTOMY, A SINGLE CENTRE EXPERIENCE

Abstract

Objectives: Our objective was to examine the results of ECMO post cardiotomy in Centro Hospitalar Universitário S. João (CHUSJ).

Methods: Between 2011 and 2019, 13 patients were cannulated for refractory cardiogenic shock post-cardiotomy; 8 (61,5%) male and 5 (38,5%) female. Patients under 18 years old were excluded. Data was collected from hospital archives concerning preoperative comorbidities, open-heart surgery procedure, dates of ECMO cannulation and decannulation, postoperative complications, hospital mortality and cause of death. Follow-up was obtained by review of the last outpatient observation. The outcomes investigated were hospital mortality and survival at 12, 36 and 60 months.

Results: After a median ECMO-VA therapy of 6 days (1-16 days), 7 (53,8%) patients were successfully decannulated; from these 2 succumbed from stroke and septic shock, one is still in intermediate care convalescing steadily and 4 were discharged. Overall 8 (61,5%) patients died. 5 (38,5%) survived, 4 were discharged home and 1 is still in intermediate care. Survival (after discharge) at 12, 36 and 60 months was respectively 25%, 16,7% and 8,3%. Regarding postoperative complications, reoperation for bleeding was necessary in 5 (38.5%), stroke was diagnosed in 2 (15,4%), dialysis in 6 (46,2%), leg ischemia affected 5 (38,5%) and mediastinitis occurred in 1 (7,7%).

Conclusions: VA ECMO saves a life in each three patients suffering from refractory cardiogenic shock after cardiac surgery. Despite risks associated with advanced cardiopulmonary support, survivors maintain good health condition.
