Objective: This study sought to generate baseline data describing Australasian intraaortic balloon counterpulsation (IABP) weaning practice. Methods: A questionnaire survey was mailed to all 192 Australasian intensive care units (ICU). Results: Response rate was 60% (n=116). The majority of hospitals informing practice were government funded public hospitals (65%), had between 100 and 500 beds (69%) and treated a minimum of 11 patients per annum with IABP (60%). The most common method of IABP support withdrawal was ratio reduction only (61%). Units most likely to undertake ratio weaning were higher end users of IABP (>21 per annum) (p=0.04). Other weaning practices involved a combination of ratio followed by volume (17%), volume then ratio (11%) and volume only (4%). Approaching statistical significance, ratio reduction weaning less frequently required IABP reinsertion or inotropic increase post balloon removal (p=0.068). Those units with documented weaning policies were less likely to require reinsertion or inotropic increase post removal (p=0.06). Criteria of importance prior to IABP weaning or removal were: blood pressure (92%); heart rate (76%); pulmonary artery wedge pressure (59%); noradrenaline dose (78%); adrenaline dose (57%); and dobutamine dose (57%). Pharmacologic escalation post balloon removal was reported between 2 and 10% by 90% of units. Balloon reinsertion was 2% or less for 87% of units. Conclusions: The Australasian approach to IABP weaning is eclectic. While ratio reduction weaning appears the most successful manner of support withdrawal, it may be a consequence of a volume outcome relationship with high end users yielding improved results through IABP familiarity.

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
