In 2006, the International Conference of Experts on Intra-abdominal Hypertension defined abdominal perfusion pressure (APP) as the difference between mean arterial pressure (MAP) and intra-abdominal pressure (IAP).The aim of the study was to analyse changes in IAP and APP in patients undergoing elective coronary artery bypass grafting (CABG). ⋯ 1) The induction of anaesthesia decreased IAP. 2) ECC resulted in an increase in IAP. 3) IAP increased in 44% of patients. 4) IAP strongly correlated with BMI and central venous pressure. 5) CABG with ECC resulted in a decrease in APP. 6) Changes in APP strongly correlated with MAP and poorly correlated with other haemodynamic parameters. 7) The changes in APP demonstrated a double-phase character.
