Chapter 53 assisting in phlebotomy

Wccc tour

The method of gaining intravenous access for the purpose of venous blood collection (also known as phlebotomy) or intravenous therapy is known as venipuncture or venepuncture in medicine. Medical laboratory scientists, medical professionals, some EMTs, paramedics, phlebotomists, dialysis technicians, and other nursing personnel conduct this technique in healthcare. [1] Veterinarians and veterinary technicians conduct the operation in veterinary medicine.
To obtain correct laboratory results, it is important to observe a standard method for collecting blood specimens. Errors in blood collection or test tube filling may lead to incorrect laboratory results. [two]
The superficial veins of the upper limb are the most common source of blood.
[1] The median cubital vein, which is situated in the cubital fossa anterior to the elbow, is close to the skin’s surface and is not surrounded by several large nerves. The cephalic, basilic, and median antebrachial veins are other veins that may be used for venipuncture in the cubital fossa. [number four]

Learning Results Define, spell, and say the words in the vocabulary list. Make a list of the venipuncture equipment you’ll need. Describe the role of a tourniquet. Explain how to use a tourniquet and the three effects of doing so incorrectly. Explain why the colors of the stoppers on evacuated tubes are different. Explain how to pick different types of tubes in the proper order. Explain why a syringe rather than an evacuated tube is used to extract blood.
Learning Results Patient venipuncture preparation should be detailed and sensitive to the patient’s rights and feelings. Identify and label the veins that could be used to gather blood. List the steps of a regular venipuncture in sequence. Using an evacuated tube, collect a venous blood sample. Explain why a winged infusion package (butterfly) was selected instead of an evacuated tube.
Learning Results List the most common issues that may arise from venipuncture. Determine the most common causes of hemolysis during a venous blood draw. List the conditions when capillary puncture will be preferable to venipuncture. Discuss the best puncture sites on the dermis. Describe the various types of containers that could be used to collect capillary blood.

Healthcare: commencement 2020

Leah Barney, a new employee at the Health Alliance Medical Center, is a recent graduate of a CMA (AAMA) program. Leah’s favorite class in the community college’s medical assisting program was medical laboratory procedures; in that class, she studied the concepts of phlebotomy and conducted many phlebotomy procedures in the school’s laboratory and at her externship location. Leah’s boss has arranged for her to spend time at the clinic with an experienced phlebotomist so that she can perform phlebotomy duties in her new job. She starts her preparation, nervous but excited.
The ancient practice of restoring the four body humors: blood, phlegm, yellow bile, and black bile, has given rise to phlebotomy, the art of drawing blood. Purging, starvation, vomiting, or bloodletting is used as the basis of all medical care to keep these humors in check.
By the Middle Ages, bloodletting had become a common activity among barbers and surgeons alike. Barbers used a red and white striped pole to advertise their services; red represented blood, and white represented the tourniquet. The pole served the stick squeezed by the patient during the operation. To cure an infection, 16 to 30 ounces (1 to 4 pints) of blood is typically drained. The “treatment” was halted when the patient passed out. Multiple incisions were commonly used to bleed over large areas of the body. George Washington is said to have died in 1799 after having 9 pints of blood drained from him in less than 24 hours to treat a throat infection. Blood, it was thought in Washington’s day, was a carrier of disease’s impurities, and that when someone bled, fresh and stable blood would replace what was lost. Bloodletting was declared quackery by the end of the nineteenth century.
