简要总结
the decrease in thoracopulmonary compliance after cardiac surgery is well known . The investigators hypothesize that the major factor determining pulmonary outcome after cardiac surgery is the alteration of pulmonary compliance during cardiopulmonary bypass(CBP) and that this alteration is due to CBP itself through pulmonary blood emptying.
详细描述
compliance is the compliance calculate when thorax is closed, the pulmonary compliance is the compliance calculated when thorax is opened After operation chest X-ray are daily done and blood samples as needed. Were recorded death, time of extubation,duration of non invasive ventilation,of Intensive Care Unit stay and of total hospital stay, troponin peak, lactates, blood gases, ionogram and count.Variations of compliance is analyzed through one factor paired Anova or Wilcoxon paired test. Decrease of compliance and respiratory complications are analyzed through binomial logistic regression.

结局指标
主要结局
pulmonary compliance during cardiac surgery
时间窗: intraoperative
compliance is calculated by dividing tidal volume (ml) by the difference between plateau-inspiratory pressure (mmHg) and end-expiratory pressure (mmHg) before ,during and after CBP
次要结局
- thoracopulmonary compliance during cardiac surgery(intraoperative)
- pulmonary complications including death after cardiac surgery(1 month)
