Weaning intraaortic balloon counterpulsation: the evidence

The aim of this paper was to determine the most effective manner to wean intraaortic balloon counterpulsation (IABP) based on research evidence. An exhaustive search of the PubMed, Medline, CINAHL, Cochrane, Science Direct and Ovid databases was carried out to source relevant literature. The search revealed a paucity of literature related to the cessation of IABP. Evidence is unanimous in suggesting the minimization of pharmacological assistance before withdrawing any form of mechanical IABP. However, opinion related to the direct weaning of IABP by either volume reduction or frequency reduction is mixed. The assimilation of IABP studies would imply volume reduction weaning to be the most effective method of IABP support withdrawal. Volume reduction offers a more physiological approach in comparison to frequency reduction weaning, which fails to significantly differ from the complete cessation of IABP treatment. When initiating the withdrawal of any IABP support, volume reduction should be the method of choice.
