Objective: To discuss the experience of combining extra-corporeal membrane oxygenation (ECMO) with intra-aortic balloon pump (IABP) for the treatment of acute heart failure in critically ill adults.
Methods: The clinical data of 54 patients who received ECMO combined with IABP due to acute heart failure between January 2008 and July 2012 were retrospectively analysed. Thirty-eight of the patients were male, and 16 were female; the mean age was 57±11. Thirty-nine of the patients received IABP first but were still unable to maintain adequate circulation, and were then given ECMO; the other 15 underwent ECMO first, but due to increased left ventricular load, the opening of the aortic valve was restricted and IABP was then introduced.
Results: Thirty-four patients (63%) were successfully weaned from ECMO; 21 patients (38.9%) survived to discharge. Major complications that occurred were renal failure (27 cases), infection (20 cases), blood plasma leakage in the oxygenator (13 cases), bleeding (18 cases), limb ischaemia (eight cases), and neurological complications (seven cases); in the group of patients who did not survive, the rates of bleeding occurrence, infection and renal failure were markedly higher than in the survived patients group. In both groups, the longer the patients were on support, the more improvement they showed in terms of MAP, CVP, Lac, SvO2 and IS.
Conclusion: ECMO and IABP may have synergistic effects and play complementary roles in the treatment of acute cardiac failure; with timely administration, active prevention and treatment of complications, they can improve treatment outcome.
