P-04 Intraoperative anastomotic site detection and assessment of LIMA to LAD anastomosis by epicardial ultrasound in off-pump coronary artery bypass grafting

display and compare the haemodynamic parameters and arterial blood gases with values taken prior to surgery in patients undergoing cardiac surgery. Method. After obtaining ethical committee approval, 100 patients scheduled for cardiac surgery, ASA grade II-IV, aged 20-72 were included. Ventilation during the transport of the patients to the ICU was performed manually. Haemodynamic parameters (HR, SAP, DAP, MAP, CVP, PAP, PCWP, CO), arterial blood gases (pH, PCO2, PO2, BE) and SpO2 values were recorded in 9 measurement times: before surgery (T1), 30 and 15 min before transport (T2 and T3), at the end of surgery (T4), at transport bed (T5), at elevator (T6), in ICU (T7), at 30th and 60th min in ICU (T8 and T9). At transport bed and elevator SAP, DAP, HR, SpO2 values were recorded. Stroke volume index (SVI) systemic and pulmonary vascular resistance indices (SVRI, PVRI) were calculated. The drugs and their dosages used during surgery and complications were recorded. Wilcoxon’s signed ranks test was used for statistics. Results. Patients received 10.6 8.5 mg midazolam, 1120.4 389.9 g fentanyl, 153.6 52.3 mg rocuronium during surgery asting 4.3 1.2 hr. 3 personnel (anaesthetist, surgeon, nurse) ere present during transport. 22 patients needed medication uring transport. Hypotension, hypertension or arrhythmias were etected in 10, 7 and 5 patients respectively.
