Even though the acute physiological effects of a needlestick injury are generally negligible, these injuries can lead to transmission of blood-borne diseases, placing those exposed at increased risk of infection from disease-causing pathogens, such as the hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV ...
This keeps blood from freely draining out of the back of the needle inserted in the vein, as each test tube is removed and the next impaled. OSHA safety regulations require that needles or tube holders come equipped with a safety device to cover the needle after the procedure to prevent accidental needle stick injury. [7]
HCV is spread primarily by blood-to-blood contact associated with injection drug use, poorly sterilized medical equipment, needlestick injuries in healthcare, and transfusions. [1] [3] In regions where blood screening has been implemented, the risk of contracting HCV from a transfusion has dropped substantially to less than one per two million. [1]
Blood poses the greatest threat to health in a laboratory or clinical setting due to needlestick injuries (e.g., lack of proper needle disposal techniques and/or safety syringes). Needles are not the only issue, as direct splashes of blood also cause transmission. [8]
A pin prick attack is an assault on another person with a needle or syringe tainted with the blood of somebody carrying a blood-borne disease, such as HIV.Although there have been numerous cases of people being attacked with needles and syringes, the idea that people infected with AIDS have deliberately attempted to infect others in this manner is generally considered an urban legend: Real ...
Assessments at this visit will include whether the at-risk person or the potential source-person are HIV positive, details around the potential HIV exposure event, including timing and circumstances, whether other high-risk events have occurred in the past, testing for sexually transmitted diseases, testing for hepatitis B and C (nPEP is also ...
A phlebotomy draw station is a place where blood is drawn from patients for laboratory testing, transfusions, donations, or research purposes. The blood is typically drawn via venipuncture or a finger stick by a healthcare professional such as a phlebotomist , nurse , or medical assistant . [ 21 ]
When the needle enters the vein, venous blood pressure generally forces a small amount of blood into the set's transparent tubing providing a visual sign, called the "flash" or "flashback", that lets the practitioner know that the needle is actually inside of a vein. The butterfly offers advantages over a simple straight needle. The butterfly's ...
