then the use of saline would avoid patient exposure to heparin-associated risks such as hypersensitivity reactions‚ local tissue damage‚ bleeding‚ and heparin induced thrombocytopenia (HIT). Saline will also increase the accuracy of the patient’s coagulation profile‚ enhancing patient management. And saline is more cost effective for institutions. But there are some studies that have shown an increase in infections when using saline over

Aetiology The aetiology of atherosclerosis is not fully understood‚ but there are certain factors that contribute to atherosclerosis plaque progression. These include genetic and acquired factors. The processes involved in atherosclerosis include coagulation‚ inflammation‚ lipid metabolism‚ intimal injury‚ and smooth muscle cell proliferation. Certain risk factors have also been identified to explain the development of atherosclerosis and these can be separated into two groups‚ genetics and environmental:

Typical assays include blood glucose testing‚ blood gas and electrolyte analysis‚ coagulation testing‚ cardiac marker diagnostics‚ drug screening‚ urine dipsticks‚ pregnancy testing‚ fecal occult blood analysis‚ food pathogen screening‚ hemoglobin diagnostics‚ infectious disease testing‚ and cholesterol screening.1 The most common POCTs used in US hospitals include glucose (99%)‚ coagulation (62%)‚ blood gas (50%)‚ chemistry (36%)‚ hematology (28%)‚ urinalysis (15%)‚ and cardiac (3%)

The effect of varying temperature on thee Rennin enzyme Abstract The purpose of this experiment was to see what affect different temperate had on the reaction rate of the enzyme rennin. The experiment was performed by placing test tubes filled with renin and milk into water bath which was heated or cooled to one of the temperatures trialed. The hypothesis justified because it found because it though data that the enzyme reacted faster with the 45° temperate because it was

NOSOCOMIAL INFECTIONS Nosocomial Infection is an infection that occurs in a hospital of hospital-like setting. Approximately 10% of American hospital patients contract this infection. There are three factors as to why nosocomial infection exists: 1. A high prevalence of pathogens. 2. A high prevalence of compromised hosts. 3. Efficient mechanisms of transmission from patient to patient. These three factors alone lead not just to a higher chance of transmission

“UNSAFE DRINKING WATER” An adequate supply of safe drinking water is one of the major prerequisites for a healthy life‚ but waterborne disease is still a major cause of death in many parts of the world‚ particularly in children‚ and it is also a significant economic constraint in many subsistence economies. The basis on which drinking water safety is judged is national standards or international guidelines. The most important of these are the WHO Guidelines for Drinking Water Quality. The quality
