About this study
Official title: Serum Level of Calpains Product as a Novel Biomarker of Acute Lung Injury Following Cardiopulmonary Bypass(CPB)
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 calpains, 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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
blood cell analysis, blood gas surveillance, chest radiograph and echocardiographyDiagnostic test
Laboratory parameters of all postoperative patients including blood cell analysis, blood gas surveillance, liver, and kidney function alone with chest radiograph and echocardiography were dynamically monitored.
| Study group | Role | What they receive |
|---|---|---|
| Lung injury group | Active comparator | Not described Receives: Diagnostic Test: blood cell analysis, blood gas surveillance, chest radiograph and echocardiography |
| Non-lung injury group | Sham comparator | Not described Receives: Diagnostic Test: blood cell analysis, blood gas surveillance, chest radiograph and echocardiography |
What is being measured
The primary outcome is the main question the study is designed to answer.
PaO2/FiO2 ratio
The ratio of inspiratory oxygen fraction to oxygen pressure (PaO2/FiO2) was calculated.
Measured: Change from beginning of CPB to 48 h after CPB
lung-injury scores
A structured tutorial was used to establish consensus in the interpretation of radiographs for radiographic lung-injury scores, range from 0 to 4.
0: No alveolar consolidation; 1: Alveolar consolidation confined to 1 quadrant; 2: Alveolar consolidation confined to 2 quadrants 3: Alveolar consolidation confined to 3 quadrants; 4: Alveolar consolidation in all 4 quadrants.
The higher scores mean a worse outcome.
Measured: The 24 and 48 hours after CPB
Secondary outcomes (1)
Perioperative serum calpains' concentrations
Serial serum samples were obtained and measured by using a fluorometric kit (Abcam, Cambridge, UK) according to the manufacturer's protocol.
Measured: The day before CPB and 1, 12, 24, 48 hours after CPB

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
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 calpains, 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.
