简要总结
Assuming that the basic reliability of dynamic indices will increase with the application of functional hemodynamic tests after sternotomy and protective lung ventilation in patients undergoing elective coronary artery bypass surgery, it is useful to predict fluid responsiveness after sternotomy in coronary artery bypass surgery patients ventilated with 6 ml/kg PBW (ideal body weight). We aimed to reveal the sensitivity and specificity of PPV and SVV changes by applying a lung opening maneuver.
详细描述
In order to evaluate the fluid deficit in patients undergoing coronary artery bypass surgery, researchers will measure stroke volume index, cardiac index and mean arterial pressure while the patients are in the lima position.
Then researchers will perform a lung opening maneuver (30mmHg for 30 seconds) and measure again.
researchers will measure again after the values return to normal. researchers will give patients balanced fluid at 3ml/kg and record their values.
Can researchers predict fluid response with lung opening maneuver?

结局指标
主要结局
Determination of fluid responsiveness in patients undergoing coronary arter bypass surgery.
时间窗: from start to 4 months
: Demonstration of fluid responsiveness in patients who will undergo coronary artery bypass surgery will prevent unnecessary fluid administration in case of hemodynamic disturbance, and medical treatments and interventions can be performed in a timely and targeted manner. Researchers will perform a recruitment maneuver on the patients and record mean arterial pressure and stroke volume index. Researchers will perform a recruitment maneuver on the patients and record mean arterial pressure and stroke volume index. Afterwards, researchers will give 3ml/cc balanced fluid to the patient and record the change in mean arterial pressure and stroke volume index.
