Abstract Background Remimazolam has less cardiovascular depressant effects than propofol in non-cardiac surgical patients. However, the efficacy and safety of remimazolam in cardiac surgery with cardiopulmonary bypass (CPB) have not been reported. We present a case of successful anesthetic management using remimazolam in cardiac surgery with CPB. Case presentation A 76-year-old female was scheduled for mitral valve repair, tricuspid annuloplasty, maze procedure, and left atrial appendage closure. We used remimazolam in induction (6.0 mg/kg/h) and maintenance (0.6–1.0 mg/kg/h) of general anesthesia, and the bispectral index value was maintained in the range of 36 to 48 including the period of CPB. Hemodynamics, mixed venous oxygen saturation, and bilateral regional cerebral oxygen saturation were maintained within acceptable ranges. There was no intraoperative awareness/recall or serious complications associated with remimazolam throughout the perioperative period. Conclusions Remimazolam can be used the same as other existing anesthetics in cardiac surgery with CPB.

Adequate oxygen delivery is crucial for organ survival. The main determinants of oxygen delivery are cardiac output, haemoglobin concentration, and arterial oxygen saturation. The adequacy of oxygen delivery also depends on oxygen consumption, which may vary widely. Mixed venous oxygen saturation reflects the amount of oxygen not extracted by the tissues, and therefore provides useful information on the relationship between oxygen delivery and oxygen needs. If not in balance, tissue hypoxia may ensue and arterial lactate concentration increases. This occurs at higher oxygen delivery rates in acute compared with chronic diseases where metabolic adaptions often occur. Arterial and mixed venous oxygen saturation are related to each other. The influence of mixed venous saturation on arterial saturation increases with an increasing intrapulmonary shunt. This chapter discusses interactions between the components of oxygen transport and how they can be evaluated. Various methods for measuring tissue oxygenation and oxygen consumption are also presented, together with their limitations.

The relationship between mixed venous and regional venous saturation during cardiopulmonary bypass (CPB), and whether this relationship is influenced by temperature, has been incompletely elucidated. Thirty patients undergoing valve and/or coronary surgery were included in a prospective, controlled and randomized study. The patients were allocated to two groups: a hypothermic group (28°C) and a tepid group (34°C). Blood gases were analysed in blood from the hepatic vein and the jugular vein and from mixed venous blood collected before surgery, during hypothermia, during rewarming, and 30 min after CPB was discontinued. Oxygen saturation in the hepatic vein was lower than in the mixed venous blood at all times of measurement (-24.0 ± 3.0% during hypothermia, -36.5 ± 2.9% during rewarming, and -30.5 ± 3.0% postoperatively, p < 0.001 at all time points). In 23% of the measurements, the hepatic saturation was < 25% in spite of normal (> 60%) mixed venous saturation. There was a statistical correlation between mixed venous and hepatic vein oxygen saturation (r = 0.76, p < 0.0001). Jugular vein oxygen saturation was lower than mixed venous saturation in all three measurements (-21.6 ± 1.9% during hypothermia, p < 0.001; -16.7 ± 1.9% during rewarming, p < 0.001; and -5.6 ± 2.2% postoperatively, p = 0.037). No significant correlation in oxygen saturation could be detected between mixed venous and jugular vein blood ( r = 0.06, p = 0.65). Systemic temperature did not influence the differences in oxygen saturation between mixed venous and regional venous blood at any time point. In conclusion, regional deoxyge-nation occurs during CPB, in spite of normal mixed venous saturation. Mixed venous oxygen saturation correlates with hepatic, but not with jugular, vein saturation. The level of hypothermia does not influence differences in oxygen saturation between mixed venous and regional venous blood.
