[A hematologic coagulation monitoring system for bedside use]

Area of Science:

• Hematology
• Anesthesiology
• Surgical Monitoring

Background:

• Perioperative hemorrhage is a significant risk factor for morbidity and mortality in surgical patients.
• Accurate and timely assessment of coagulation status is crucial for managing surgical bleeding.
• Existing monitoring methods may not provide a comprehensive or rapid evaluation of hemostasis.

Purpose of the Study:

• To evaluate the utility of a novel bedside hematologic monitoring system for assessing coagulation.
• To determine the diagnostic accuracy of the system in detecting clotting abnormalities.
• To explore its potential for early diagnosis and treatment of postoperative coagulopathy.

Main Methods:

• A bedside hematologic monitoring system was developed, integrating DRIHEMATO SYSTEM COAG-1 (measuring prothrombin time [PT], activated partial thromboplastin time [APTT], and fibrinogen [FIB]) with platelet count (PLT), activated clotting time (ACT), and thromboelastography (TEG).
• The system was tested in 10 adult patients undergoing cardiopulmonary bypass.
• Specificity for detecting clotting abnormalities was calculated for PT, FIB, and TEG.

Main Results:

• The monitoring system demonstrated high specificity for detecting clotting abnormalities: PT at 88%, FIB at 100%, and TEG at 67%.
• The combination of tests provided a comprehensive hematologic assessment at the bedside.
• Individual component specificities suggest varying degrees of utility for specific coagulation parameters.

Conclusions:

• The developed bedside hematologic monitoring system shows potential for the early diagnosis and management of postoperative coagulopathy.
• Integrating multiple coagulation parameters offers a more complete picture of hemostasis.
• Further studies are warranted to confirm its clinical efficacy and impact on patient outcomes.
