Methods We studied 50 patients scheduled for coronary artery bypass surgery and we compared data from patients who exhibited pruritus with those from patients who did not. After the monitoring devices had been positioned vancomycin 15 mg kg was continuously infused at a constant rate over 30 min before induction of anaesthesia. Haemodynamic profiles were recorded before vancomycin infusion time point 1 at 15 time point 2 and 30 min time point 3 after the beginning of vancomycin infusion and 15 min after vancomycin infusion had been stopped time point 4 . At each time arterial and mixed venous blood samples were drawn to calculate the shunt fraction Qsp Qt . Results In patients who exhibited pruritus group A n 17 at
