Survey on Cardiogenic Shock and the Use of ECMO and Impella in Spanish Cardiac Critical Care Units

Abstract

Background: Previous studies suggest variability in the management of cardiogenic shock (CS). Methods: An anonymous survey was sent to Spanish hospitals. Results: We obtained 50 answers, mainly from cardiologists (36–72%). The annual average of ECMOs is 16.7 ± 11.3 applications in CS patients and of Impellas is 8.7 ± 8.3 applications in CS patients. Intra-aortic balloon counterpulsation is used in the majority of CS ECMOs (31–62%), and Impella is used in 7 (14%). In 36 (72%) cases, ECMO is used as a treatment for cardiac arrest. In 10 cases, ECMO removal is percutaneous (20%). In 25 (50%) cases, age is a relative contraindication; 17 have a mobile ECMO team (34%); and 23 (46%) have received ECMO patients from other centers in the last year. Pre-purged ECMO is only used in 16 (32%). ECMO implantation is carried out under ultrasound guidance in 31 (62%), only with angiography in 3 (6%) and with both in 11 (22%). The Swan–Ganz catheter is used routinely in 8 (16%), only in doubtful cases in 24 (48%), and in most cases in 8 (16%). The ECMO awake strategy is used little or not at all in 28 (56%), in selected cases in 17 (34%), and routinely in 5 (10%). Conclusion: Our study shows a huge variation in the management of patients with CS.
