and the need for coagulation products with the c-index used to judge the quality of model prediction and the Youden J-index in receiver operating characteristic (ROC) curve analysis to determine the optimal cut-off values for TEG parameters and the platelet fibrinogen product.{Katz, 2011 #408} We developed a ROC curve based on a simplified predictive algorithm according to the number of predictors (using their respective cut-off values) to characterize the accuracy (i.e., area under the curve),…

This disease is often found when a person is going to the doctor for a routine checkup; their labs usually show an increased amount of blood cells of all types. The patient’s hemoglobin the day of clinical was 8.8; his platelets were 641. Ultrasonography is a type of diagnostic tool used to screen for any type of tumors that may have precipitated the illness. The most common types that cause polycythemia are kidney and liver tumors. The kidneys produce erythropoietin; these are what generates…

What is autologous blood? What are the contraindications? Cell saver: • Anticoagulates blood, spins out RBCs, washes cells with saline • All platelets and coagulants are removed • HCT is approximately 50-60% Contraindications: 1. Malignant cells 2. Contamination (bacteria, amniotic fluid) 3. Topical clotting agents Most Common Serious Complication: 1. Air Embolism 49. What is acute normovolemic…

the decline in coronary perfusion? a) Heart Rate b) Contractility c) High blood pressure d) Platelet aggregation and thrombosis Answer: D Answer Rationale: A. (Incorrect) Heart rate and coronary perfusion is not correlated. An increase or decrease in heart rate along does not necessarily impact the coronary perfusion. In most cases, it is the vasodilation and vasoconstriction in either health or platelet aggregated vessels that impact coronary perfusion. B. (Incorrect) Any change in the…

One thousand- It seems to be a fairly large number, but in some cases, especially mine, it can be extremely small. The average person has from one hundred and fifty thousand to four hundred thousand blood platelets, yet there are times where I found myself with as low as one thousand of them. It was in times like those were I looked up to courageous people like Jackie Robinson, who faced difficulties head on with no fear. I quietly sat in the airport boarding gate with my eyes screwed shut,…

clot formation in the small vessels throughout the body. The pathophysiology is excess thrombin is generated, followed by deposition of fibrin strands in the body tissues.” (Ball, 2012) “The circulating fibrin fragments later begin to interfere with platelet aggregation and other aspects of the clotting mechanism, resulting in bleeding or hemorrhage.” (Lewis, 2014). DIC can be acute or chronic, most people think it’s only acute. Signs and symptoms of disseminated intravascular coagulation…

Although we do not yet fully understand their origin or their impact, the platelets and tangles of proteins that form in the brain appear to be playing a crucial role in degrading neural connections and ultimately killing neurons. Plaques are deposits of protein building up between neurons. Tangled are twisted fibres of protein…

has on many Americans each and every day. A myocardial infarction or what’s mostly known as a heart attack happens when a heart muscle doesn’t receive enough blood flow to sustain muscle activity. This occurs when the blood vessel is damaged and platelets clot up the damage to prevent bleeding. Over a long…

The mechanism of action of rivaroxaban involves the competitive inhibition of factor Xa. Factor Xa, a crucial component of the common pathway of the clotting cascade, normally binds with prothrombin on the surface of activated platelets and catalyzes the hydrolysis of prothrombin into its active form, thrombin (Pratt & Cornely, 2014, pp. 177-178). Since factor Xa is the first synthesized component of the common pathway of the clotting cascade, the inhibition of this clotting factor…

marrow development. The symptoms of this disorder is very similar to a type of cancer known as leukemia. The condition is diagnosed by several tests that include blood tests which shows the levels of the white blood cells, red blood cells and the platelet count, and finally a bone marrow biopsy is done to confirm the diagnosis. This condition was once considered incurable, but now with the proper treatment, it is curable and many live a normal healthy life afterwards The condition aplastic…
