Design outcomes

Primary

MeasureTime frame
In cardiac surgery patients, the diameter of the inferior vena cava is determined by ultrasound preoperatively and postoperatively intubated and postoperatively extubated.

Secondary

MeasureTime frame
In cardiac surgery patients, the presentation of liver vein, portal vein, renal vein is determined by ultrasound preoperatively and postoperatively intubated and postoperativelv extubated.
