Impact of perioperative haemodynamic monitoring on cardiac morbidity after major vascular surgery in low risk patients. A randomised pilot trial

Objective: to evaluate whether perioperative haemodynamic optimisation influences outcome frown 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 (Cl > 3.0 l/min/sqm, PWP > 10 and <18 mmHg SVR <1450 dyne/sec/cm(-5), DO2 > 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.
