converted to an active protease that activates the next clotting factor, and finally, a solid clot is formed”(Woo & Wynne, 2011, p. 445). The process of clot formation and dissolution of the clot following repair of the injured tissue is termed hemostasis and is comprised of four major events: 1. Initial Phase: Vascular constriction in which the flow of blood to the area of injury is limited and Factor VII is activated. 2. Second Phase: Platelets become activated by thrombin and aggregate at the

Abstract Hypovolemic shock as a result of blood loss was once viewed as a death sentence. Today, as a result of numerous advancements in medicine, it is considered a treatable condition, to an extent. In regards to traumatic mortality, hemorrhage causes thirty to forty percent of deaths. (Kauvar, Lefering, and Wade, 2006). This shows that pre-hospital management of both hemorrhage and the resulting shock are crucial for positive patient outcome. The question becomes, how can providers provide the

If you have heart failure, you are not alone. Currently, approximately 5.7 million people in the United States live with it. In fact, it is one of the most common reasons why people 65 years of age or older admitted to hospital. The development of heart failure can take years. Heart failure is called congestive heart failure when fluids accumulate in various parts of the body. So if you do not already have, but runs the risk of suffering, you should change your lifestyle now! Symptoms of heart failure

1.HEMOSTASIS OVERVIEW Hemostasis is the normal physiological response that prevents significant blood loss after vascular injury which is essential in survival. Hemostasis is a complex process helps close off damaged blood vessels, keep blood in a fluid state and dissolve blood clots following restoration of vascular integrity. Hemostasis is now also known to play an important role in wound healing and endothelial barrier protection and function. (1) The process consists of a complex regulated system

and retract through the phases depending on various factors within the patients. Inflammatory phase Inflammatory phase can be further divided into hemostasis and inflammation, which is triggered immediately and last for about two to five days succeeding injury. Hemostasis Hemostasis is the process which halts bleeding after an injury. During hemostasis, the initial wound stimulates vasoconstriction in the wound bed to diminish blood loss while the exposure of collagen from the wound site causes the

cascades of events in wound healing process. They are hemostasis, inflammation, migration, proliferation and maturation. The first stage includes hemostasis and inflammation, which occurs soon after the damage of skin. Fibrinogen is one of the major components of the skin connective tissues, leads to the coagulation of exudates, and together with the formation of a fibrin network, produces a clot in the wound which stops. Therefore, both hemostasis and inflammatory stages play an important role in the

blood is extremely vital to life. Although its range is only from 7.35 – 7.45, it is the only range through which chemical reactions in the body can occur. Third, blood is a protective tissue which prevents blood loss through a process called hemostasis which is, “the process by which the body stops blood loss.” Blood has several interesting properties including volume, viscosity, and density. Surprisingly, although blood is man’s life source, an adult’s body only contains

Virus one of the hotly debated topic in today’s society has been blamed for many illnesses and complication. According to Britannica encyclopedia a “virus, is an infectious agent of small size and simple composition that can multiply only in living cells of animals, plants, or bacteria”. To explain the theory of whether viruses is alive of dead let look at the following. Living things must be able to reproduce, grow and develop and some these principles exhibit by viruses when they enter the host

Regardless of SBP or limb circumference Pauers et al. used standard 250 mmHg and reported that adequate hemostasis was achieved in all cases (8). Several studies investigated the soft tissue pressure distribution under a tourniquet cuff with limbs of human cadavers and dogs. These studies showed that tissue pressures are consistently less than tourniquet pressures

VITAMIN K AND BLOOD CLOTTING Vitamin K is a naturally occurring vitamin, a fat-soluble vitamin. It is recognized for its role in the process of formation of blood clotting ("K" is derived from the German word "koagulation"), it is essential for the functioning of many proteins that are involved in many physiological processes (Brody T, 1999). There are two forms of naturally occurring vitamin K that are known as vitamin K1 and vitamin K2 (Figure 1). Vitamin K1 or other name is phylloquinone is synthesized

Abstract: Bleeding is a common outcome of periodontal or oral surgery, but there is currently conflicting data suggesting that isotretinoin may have an adverse effect on wound healing, specifically from dental procedures such as periodontal treatments; these patients, characterized by a tendency to bleeding, constitute a serious challenge in the dental practice. Although advances in the medical diagnosis of hemostatic disorders have exposed dental professionals to new patients not agreeable to the

Then, antibiotics, surgery, anti-inflammatory agents, or obstetric procedures may regulate hemostasis, mainly in chronic DIC. However, in acute phase of DIC, two categories of treatment are available as follows: treatments that slow the coagulation process and therapies that substitute the coagulation factors and the missing platelets. Heparin also

As always, an assessment of airway, breathing, and circulation is the topmost priority. Protection of the airway with intubation may be needed to avoid respiratory compromise from potential aspiration of blood and gastric contents, especially in patients with active bleeding and altered mental status (6). All patients who present with signs and symptoms of UGIB should be evaluated immediately for hemodynamic stability and managed accordingly by rapid intravascular volume replacement with isotonic

OXYGENATION STATUS (oxygen-carrying capacity): Hemoglobin, Hematocrit, RBC count, Mean RBC volume IMMUNE STATUS (signs of infection, allergy, immune suppression): Neutrophils, Basophils, WBC count HEMOSTASIS (blood clotting): Platelets 2. Review the measurements in the CBC. For each abnormal value, describe what physiological effect it might have on the patient. Connect each of your descriptions to one or more of the symptoms Harold has been experiencing

aligned correctly to rebuild the tissue integrity. Inflammation happens when the skin is injured and up to 24 hours afterwards. The immune system reacts to fight off infection and expedite the healing process and coagulation occurs to establish hemostasis. The regeneration phase starts to restore skin integrity with the renovation of new blood cells (Bronneke, 2015). This process is called angiogenesis and is significant to this process. Granulation tissue soon appears and scarring begins to form

Elevation of the intraocular pressure (fluid pressure inside the eye) is considered as a risk factor for some ocular disorders specially glaucoma, which can eventually lead to blinding. Current treatments for this disease focus on lowering intraocular pressure (Zeng et al. 2010). Such pressure elevation within the eye is believed to be due to an increase in the resistance to aqueous humour outflow from the eye, but the exact origin of this resistance increase has not been determined yet (Johnson

Laparoscopic splenectomy is preferred over open splenectomy as it is safe and effective.29It has an exclusion criterion for the following cases; trauma, portal hypertension and high anesthesia risk due to cardiorespiratory and allied conditions.29 A patient with an indication for splenectomy has to undergo a few preoperative examinations as well as vaccinations. A spiral CT scan is used to check the size and volume of the spleen, as well as accessory splenic tissue preoperatively.30 Vaccination against

ESC Biomarkers and their role in wound healing Wound healing involves a complex orchestration of processes that suppress infection and restore the dermal barrier. Healing begins immediately following the laceration to the epidermis with hemostasis, which includes initial vasoconstriction and thrombocyte clumping. Following is an influx of fibroblasts (which help clot the wound opening), and inflammatory macrophages. Next, granulation tissue creates a framework for forming permanent connective tissue
