| We analysed the effects of these two anaesthetic regimens, used in order to maintain the same depth of anaesthesia, during the early postoperative period: 1. Haemodynamic effects: Standard monitoring was used and included a CCO/SvO2 pulmonary artery catheter (Edwards Lifesciences, USA) 2. The following haemodynamic parameters were recorded every 30 minutes from H0 to H4 (duration of the sedation), then hourly until H8 and finally every 2 hours for the next 16 hours: 2.1. Heart rate (HR) 2.2. Invasive mean arterial pressure (mean AP) 2.3. Central venous pressure (CVP) 2.4. Mean pulmonary arterial pressure (mean PAP) 2.5. Pulmonary capillary wedge pressure (PCWP) 2.6. Continuous cardiac output (CCO) 2.7. Cardiac index (CI) 2.8. Mixed venous oxygen saturation (SvO2) 3. Biochemical markers of myocardial damage including troponine I and CPK-MB were analysed before surgery, and repeated at H0, H3, H8, H16 and H30 4. Respiratory effects: Arterial blood gases evaluated respiratory state, every 4 hours from H0 to 24 hours after extubation 5. Pain management: Pain evaluation was assessed by VAS ranging from 0: no pain to 100: worst imaginable pain. Each evaluation was performed at rest and just after deep inspiration (stress test). Use of VAS score and PCA recording of piritramide requirements evaluated the efficacy of pain control. | — |
