Impact of Perioperative Haemodynamic Monitoring on Cardiac Morbidity after Major Vascular Surgery in Low Risk Patients. A Randomised Pilot Trial

Abstract Objective : to evaluate whether perioperative haemodynamic optimisation influences outcome from infrarenal abdominal aortic aneurysm repair. Methods : a consecutive series of 100 eligible patients were randomised to either haemodynamic optimisation through the use of a pulmonary artery catheter (CI > 3.0 l/min/sqm, PWP > 10 and −5 , DO 2 > 600 ml/min/sqm) or conventional treatment. Results : there were no differences in terms of in-hospital mortality, cardiovascular morbidity, postoperative renal failure or duration of hospital stay between the groups. Conclusions : in this study perioperative haemodynamic optimisation was not beneficial.
