Effectiveness of Intra- Aortic Ballon Pump (IABP) Insertion as Rescue Mechanical Support for on Pump Coronary Artery Bypass Surgery Patients with Persistent Intraoperative Hemodynamic Instability.

Background: Aim: Aim of this study was to evaluate the efficacy of IABP as a rescue mechanical support intra-operatively in persistent hemodynamic instability in a group of patients who have undergone elective CABG surgery.Subjects and Methods: It is a retrospective study conducted on patients who have undergone on pump CABG and received rescue IABP support intraoperatively.The IABP was inserted in the presence of hemodynamic instability as a rescue, inserted percutaneously via right or left femoral artery approach.Results: There is a marginal increase in the duration of mechanical ventilation 68.99±30.93hours and duration of ICU stay 5.97±1.93days.All patients had significant ST-T changes in more than 2 leads.No major complications related to IABP were recorded.An echocardiogram shown significant improvement in EF (p value=<0.0001).No in-hospital and 30 days mortality was recorded.Conclusion: This study shows significant improvement in hemodynamics post IABP insertion; improvement in EF at discharge from hospital and no mortality at discharge from hospital and 30 days postoperatively.IABP also decreased the postoperative length of stay.Preoperative IABP suggesting that it is effective in patients with severe LV dysfunction undergoing OPCAB.
