Overview

This study compares the results of the existing fibrinogen concentration monitoring technology to the Electrochemical-based device, a point-of-care and rapid method,using a small amount of extra blood obtained in Type A Aortic Dissection Surgery.

Detailed description

Electrochemical-based device for rapid detection of fibrinogen is a novel POC diagnostic method, which is suitable for operating theatres and emergency rooms.

The novel fibrinogen detection based on Gel electrodes combined with immunobiosensing strategies and use magnitude of current to characterize the fibrinogen concentration , which will be a POC assay of fibrinogen detection for critically ill patients.

This single-center, prospective, observational pilot study will evaluate the analytical performance as well as compared to conventional Clauss laboratory reference method.

Interventions

  • Diagnostic test the Electrochemical-based device
    Electrochemical-based device for rapid detection of fibrinogen is a novel POC diagnostic method, which is suitable for operating theatres and emergency rooms.

Primary outcome measures

  • The fibrinogen concentration values obtained using the Clauss method and electrochemical method were compared [Time frame: 1 day]
Secondary outcome measures (1)
  • the time of the two detection methods [Time frame: 1 day]

Eligibility criteria

Part1 Phase I-Laboratory calibration. The electrochemical method was employed to detect the fibrinogen concentration of standard quality control materials with varying concentration gradients, and the corresponding current values were recorded for constructing a standard curve of fibrinogen concentration.

Phase II-Assay performance using clinical samples. Subject is 18 years and underwent routine hemostasis analysis. using human biological samples already collected for routine hemostasis analysis, The samples were centrifuged at 2500g for 15 min at room temperature, to obtain PPP (residual platelet count of <10 × 10\^9/L) and stored at-20℃used for determination by electrochemical method within 2 weeks, Each clinical sample was tested three times

Part2

Inclusion criteria

Subject underwent surgery for acute type A aortic dissection at our hospital, Subject is 18 years, Subject requires routine TEG measurement, Subject use human fibrinogen concentrate during surgery.

Exclusion criteria

Use Extracorporeal Membrane Oxygenation after surgery, inability to obtain written informed consent
