AbstractTo avoid perioperative cardiac complications and deterioration of renal function in chronic kidney disease (CKD), anesthesiologists are required to manage respiration and circulation properly. Three mechanisms are considered to worsen renal function during inappropriate mechanical ventilation; first, hypercapnia or hypoxemia, second, unstable systemic hemodynamic, and third, systemic inflammatory mediators derived from pulmonary biotrauma. Many circulatory problems are present in CKD patients, for example, hypertension, cardiac hypertrophy, cardiomyopathy, ischemic heart disease, arterial sclerotic valve disease, salt and water retention etc. Blood pressure in CKD patients should be controlled properly before surgery. Renal blood flow and renal perfusion pressure should be maintained by aggressive fluid therapy to avoid perioperative acute kidney injury (AKI) on CKD, while cardiac congestion should also be avoided. Perioerative renal protective effects of human atrial natriuretic peptide (hANP) on CKD still needs further investigation. Appropriate hemodynamic monitoring, including direct arterial pressure, left ventricular preload, intravascular volume and cardiac output could be helpful for anesthesiologists to manage CKD patients safely. In the area of CKD and anesthesia, there is lack of evidence in respiratory and circulatory strategies. Prospective studies in these aspects are required in the future.
