Summary
Thromboelastography (TEG) reveals critical insights into blood coagulation. Specific TEG parameters, particularly maximum amplitude (MA), can predict long-term survival in critically ill patients.
Area of Science:
- Critical care medicine
- Hematology
- Coagulation diagnostics
Background:
- Thromboelastography (TEG) monitors blood coagulation in critically ill patients.
- The relationship between TEG parameters and long-term survival is not well-established.
Purpose of the Study:
- To investigate the impact of TEG on the long-term survival of critically ill patients.
- To identify specific TEG parameters that predict survival outcomes.
Main Methods:
- Retrospective analysis of 167 critically ill patients who underwent TEG.
- Comparison of baseline characteristics and coagulation indexes.
- Application of Cox regression, ROC curve analysis, and Kaplan-Meier survival analysis.
Main Results:
- Patients who died had higher clot formation speed (K) and reaction time (R), and lower maximum amplitude (MA) and angle (P < .01).
- All TEG parameters were identified as risk factors for 2-year survival (P < .01).
- Maximum amplitude (MA) demonstrated strong predictive value for 2-year survival with an AUC of 0.756.
Conclusions:
- Maximum amplitude (MA) effectively predicts 2-year survival in critically ill patients.
- TEG parameters, especially MA, highlight the significant role of the coagulation system in patient outcomes.
- TEG can serve as a valuable tool for prognostic assessment in critical care.

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

Nursing management begins with a thorough assessment of the patient's health history. Key factors include trauma to veins, peripherally inserted central catheters, varicose veins, recent pregnancy or childbirth, surgery, bacteremia, prolonged bed rest, atrial fibrillation, COPD, heart failure, cancer, coagulation disorders, myocardial infarction, spinal cord injury, stroke, prolonged travel, recent bone fractures, and dehydration. Review medication intake, particularly oral contraceptives,...

A pulmonary embolism occurs when a thrombus, amniotic fluid, tumor tissue, fat, or air embolus blocks one or more pulmonary arteries. Effective nursing management and patient education are crucial for improving outcomes and preventing recurrence.Nursing management starts with obtaining a comprehensive patient history, particularly noting any history of deep vein thrombosis (DVT). Assess for clinical manifestations, including dyspnea, chest pain, crackles, heart murmurs, and signs of right-sided...

The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...
