Multicenter StudyComplications of intra-aortic balloon pump use: does the final position of the IABP tip matter?
We report results of a retrospective review of intra-aortic balloon pump (IABP) use in two Australasian centres and evaluate the effect of final IABP tip position on outcome. Indications for counterpulsation, patient demographics and in-hospital outcomes and complications were retrospectively collected. The chest X-ray reports provided the 'final' position of the IABP tip. ⋯ Severe renal impairment was the most common complication (16.6%), and second, severe catheter dysfunction (5.4%). ?Final IABP position was acceptable in 39.9%, malpositioned in 11.1%,?severely malpositioned in 6.7% and unavailable for 42.4%. Logistic regression analysis showed IABP tip malposition (compared with satisfactory position odds ratio=3.9 [95% confidence interval=2.0-7.6, P < 0.001] and severely malpositioned odds ratio=13.0 [95% confidence interval 5.3-31.7, P < 0.001]) was associated with major complications more than the presence of shock (odds ratio=3.8, confidence interval=2.1-6.8 P < 0.001). The acceptance of a less-than-ideal final position was highly predictive of morbidity directly related to IABP device therapy.
