Details and patient eligibility

About

More than 2 million patients worldwide receive heart surgery every year, majority of these surgical patients will undergo cardiopulmonary bypass. However, the incidence of postoperative acute lung injury due to cardiopulmonary bypass is still as high as 20% to 35%. According to clinical experience, the earlier lung damage is detected, the more successful the treatment will be. On the basis of traditional detection, the investigators found a new indicator, serum soluble vascular endothelial-cadherin, which are easy to obtain and have certain specificity. Importantly, they can predict postoperative acute lung injury within 1 hour after cardiac surgery. It is meaningful that this indicator can provide clinicians with early decision-making advice and immediate treatment for patients who may be at risk.

---

100 participants in 2 patient groups

Lung injury group

Active Comparator group

Description:

Lung injury is defined as lung damage when the patient has an oxygen and index below 300 24 hours after cardiopulmonary bypass

Treatment:

Diagnostic Test: blood cell analysis, blood gas surveillance, chest radiograph and echocardiography

Non-lung injury group

Sham Comparator group

Description:

Patients with oxygen and an index above 300 24 hours after cardiopulmonary bypass are defined as non-lung injury

Treatment:

Diagnostic Test: blood cell analysis, blood gas surveillance, chest radiograph and echocardiography
