What is Venipuncture? While venipuncture can refer to a variety of procedures, including the insertion of IV tubes into a vein for the direct application of medicine to the blood stream, in phlebotomy venipuncture refers primarily to using a needle to create a blood evacuation point. As a phlebotomist, you must be prepared to perform venipuncture procedures on adults, children, and even infants while maintaining a supportive demeanor and procedural accuracy. Using a variety of blood extraction tools, you must be prepared to respond to numerous complications in order to minimize the risk to the patient while still drawing a clean sample. In its entirety, venipuncture includes every step in a blood draw procedure—from patient identification to puncturing the vein to labeling the sample. Patient information, needle placement, and emotional environment all play a part in the collection of a blood sample, and it's the fine details that can mean the difference between a definite result and a false positive. After placing the tourniquet and finding the vein, it's time for the phlebotomist to make the complex choice on what procedure will best suit the specific situation. Keeping this in mind, it should be noted that the following information is not an instructional guide on how to perform these phlebotomy procedures. Rather, the information below is intended to serve as an educational resource to inform you of the equipment and procedures you will use. Venipuncture Technqiues Venipuncture with an Evacuated or Vacuum Tube: This is the standard procedure for venipuncture testing. Using a needle and sheath system, this procedure allows multiple sample tubes to be filled through a single puncture. This procedure is ideal for reducing trauma to patients. After drawing the blood, the phlebotomist must make sure the test stopper is correctly coded and doesn't contact exposed blood between samples. Venipuncture with a Butterfly Needle : This is a specialized procedure that utilizes a flexible, butterfly needle adaptor. A butterfly needle has two plastic wings (one on either side of the needle) and is connected to a flexible tube, which is then attached to a reservoir for the blood. Due to the small gauge of the needle and the flexibility of the tube, this procedure is used most often in pediatric care, where the patients tend to have smaller veins and are more likely to move around during the procedure. After being inserted into a vein at a shallow angle, the butterfly needle is held in place by the wings, which allow the phlebotomist to grasp the needle very close to the skin. Phlebotomists should be careful to watch for blood clots in the flexible tubing. Venipuncture with a Syringe: This technique is typically only used when there is a supply shortage, or when a technician thinks it is the appropriate method. It uses the classic needle, tube, and plunger system, operating in a similar manner to the vacuum tube but requiring multiple punctures for multiple samples. Additionally, after the blood is drawn it must be transferred to the appropriate vacuum tube for testing purposes. If you choose to use this method, remember to check for a sterile seal, and use a safety device when transferring the sample. Fingerstick (or Fingerprick): This procedure uses a medical lance to make a small incision in the upper capillaries of a patient's finger in order to collect a tiny blood sample. It is typically used to test glucose and insulin levels. When performing a Fingerstick, the phlebotomist should remember to lance the third or fourth finger on the non-dominant arm. Never lance the tip or the center of the finger pad; instead, lance perpendicular to the fingerprint lines. Heelstick (or Heelprick): Similar to the Fingerstick procedure, this process is used on infants under six months of age. A medical lance is used to create a small incision on the side of an infant's heel in order to collect small amounts of blood for screening. As with a Fingerstick, the incision should be made perpendicular to the heel lines, and it should be made far enough to the left or right side of the heel to avoid patient agitation. Before performing a Heelstick, the infant's heel should be warmed to about 42 degrees Celsius in order to stimulate capillary blood and gas flow. Therapeutic Phlebotomy: This involves the actual letting of blood in order to relieve chemical and pressure imbalances within the blood stream. Making use of a butterfly needle, this therapy provides a slow removal of up to one pint of blood. Though the blood removed is not used for blood transfusions, the procedure and concerns are the same as with routine blood donation. As with any phlebotomy procedure, one should pay close attention to the patient in order to prevent a blood overdraw. Bleeding Time: A simple diagnostic test that is used to determine abnormalities in blood clotting and platelet production. A shallow laceration is made, followed by sterile swabbing of the wound every 30 seconds until the bleeding stops. Average bleed times range between one and nine minutes. As a phlebotomist, you should familiarize yourself with the application and cross-application of these procedures in order to recognize when a procedure is necessary, and what the risks are for each.

Beta blockers, also known as beta-adrenergic blocking agents, are medications that reduce your blood pressure. Beta blockers work by blocking the effects of the hormone epinephrine, also known as adrenaline. When you take beta blockers, your heart beats more slowly and with less force, thereby reducing blood pressure. Beta blockers also help blood vessels open up to improve blood flow. Examples of beta blockers Some beta blockers mainly affect your heart, while others affect both your heart and your blood vessels. Which one is best for you depends on your health and the condition being treated. Examples of oral beta blockers include: Acebutolol (Sectral) Atenolol (Tenormin) Bisoprolol (Zebeta) Metoprolol (Lopressor, Toprol-XL) Nadolol (Corgard) Nebivolol (Bystolic) Propranolol (Inderal LA, InnoPran XL)
Calcium channel blockers prevent calcium from entering cells of the heart and blood vessel walls, resulting in lower blood pressure. Calcium channel blockers, also called calcium antagonists, relax and widen blood vessels by affecting the muscle cells in the arterial walls. Some calcium channel blockers have the added benefit of slowing your heart rate, which can further reduce blood pressure, relieve chest pain (angina) and control an irregular heartbeat. Examples of calcium channel blockers Some calcium channel blockers are available in short-acting and long-acting forms. Short-acting medications work quickly, but their effects last only a few hours. Long-acting medications are slowly released to provide a longer lasting effect. Several calcium channel blockers are available. Which one is best for you depends on your health and the condition being treated. Examples of calcium channel blockers include: Amlodipine (Norvasc) Diltiazem (Cardizem, Tiazac, others) Felodipine Isradipine Nicardipine Nifedipine (Adalat CC, Afeditab CR, Procardia) Nisoldipine (Sular) Verapamil (Calan, Verelan) In some cases, your doctor might prescribe a calcium channel blocker with other high blood pressure medications or with cholesterol-lowering drugs such as statins.
Atopic dermatitis (eczema) is a condition that makes your skin red and itchy. It's common in children but can occur at any age. Atopic dermatitis is long lasting (chronic) and tends to flare periodically and then subside. It may be accompanied by asthma or hay fever.
Chickenpox (varicella) is a viral infection that causes an itchy rash with small, fluid-filled blisters. Chickenpox is highly contagious to people who haven't had the disease or been vaccinated against it. Before routine chickenpox vaccination, virtually all people had been infected by the time they reached adulthood, sometimes with serious complications. Today, the number of cases and hospitalizations is down dramatically. For most people, chickenpox is a mild disease. Still, it's better to get vaccinated. The chickenpox vaccine is a safe, effective way to prevent chickenpox and its possible complications.
Vaginal discharge serves an important housekeeping function in the female reproductive system. Fluid made by glands inside the vagina and cervix carries away dead cells and bacteria. This keeps the vagina clean and helps prevent infection. Most of the time, vaginal discharge is perfectly normal. The amount can vary, as can odor and hue (its color can range from clear to a milky white-ish), depending on the time in your menstrual cycle. For example, there will be more discharge if you are ovulating, breastfeeding, or are sexually aroused. The smell may be different if you are pregnant or you haven't been diligent about your personal hygiene. None of those changes is cause for alarm. However, if the color, smell, or consistency seems significantly unusual, especially if it accompanied by vaginal itching or burning, you could be noticing an infection or other condition. What causes abnormal discharge? Any change in the vagina's balance of normal bacteria can affect the smell, color, or discharge texture. These are a few of the things that can upset that balance:
Inflammation of the uvula is known as uvulitis. Your uvula will appear red, puffy, and larger than normal. Other symptoms of uvulitis may include: itching burning a sore throat spots on your throat snoring difficulty swallowing trouble breathing If you have a swollen uvula along with a fever or abdominal pain, consult with your doctor right away. In rare cases, the uvula can swell enough to block your airway. Swelling of the throat is a life-threatening event. If this happens, seek immediate medical attention. What causes a swollen uvula? Causes Inflammation is your body’s response when it’s under attack. Triggers for inflammation include: environmental and lifestyle factors an infection trauma genetics Environmental and Lifestyle Factors The most common food allergies are peanuts tree nuts milk eggs wheat soy fish, including shellfish You could be having an allergic reaction to something you touched, swallowed, or breathed in. Some common allergens include: food irritants , such as dust, animal dander, or pollen medication exposure to chemicals or other toxic substances, including tobacco Infection You can get viral infections or bacterial infections. Examples of viral infections include: the common cold the flu mononucleosis chickenpox measles croup The most common bacterial infection is strep throat, which occurs due to Streptococcus pyogenes, which is a type of group A Streptococcus. If you have infected tonsils, or tonsillitis, severe inflammation can cause them to push against and irritate your uvula. Trauma Trauma to the uvula can happen if you need an intubation, such as during surgery. Your uvula can also be injured during a tonsillectomy. This is a procedure to remove your tonsils, which are located on both sides of your uvula. Your throat and uvula can also become irritated if you have acid reflux disease or if you vomit frequently. Genetics A condition called hereditary angioedema (HAE) can cause swelling of the uvula and throat, as well as swelling of the face, hands, and feet. Other symptoms include nausea, vomiting, and abdominal pain. It’s an uncommon genetic mutation that occurs in 1 in 10,000 to 1 in 50,000 people. It’s rare, but there are case reports of individuals who have an elongated uvula, which can also interfere with breathing. What are the risk factors for a swollen uvula? Risk Factors Anyone can get uvulitis, but adults get it less often than children do. You’re at increased risk if you: have allergies use tobacco products are exposed to chemicals and other irritants in the environment have a weakened immune system, making you more susceptible to infections How is a swollen uvula diagnosed? Diagnosis If you have fever or swelling of your throat, see your doctor. Be prepared to give a complete medical history. Tell your doctor: about all the over-the-counter and prescription medications you take if you’re a smoker or you chew tobacco if you’ve recently tried new foods if you’ve been exposed to chemicals or unusual substances about your other symptoms, such as abdominal pain, fever, or dehydration Your doctor may be able to make a diagnosis through a physical exam. It’s likely you’ll also need a throat swab to evaluate for strep or to obtain secretions for culture to determine if you have another bacterial or fungal infection. This test is known as the rapid strep test. You may also need a nasal swab to test for influenza. Blood testing can help identify or rule out some other infectious agents. If those tests are inconclusive, you may need to see an allergist. Blood and skin tests can help identify foods or other substances that cause a reaction.

Treatment When you have something like the common cold, swelling usually clears up on its own without treatment. Otherwise, treatment will depend on how severe your symptoms are, as well as what’s causing the inflammation. Infection Viral infections tend to clear up without treatment. The only upper respiratory infection for which an antiviral medication is available is influenza. Antibiotics can treat bacterial infections. Even after symptoms clear up, take all the medication as prescribed. If your condition may be contagious, stay home until your doctor tells you that you’re no longer at risk of spreading it to others. Allergy If you test positive for an allergy, try to avoid the allergen in the future. Doctors usually treat allergies with antihistamines or steroids. Anaphylaxis is a severe allergic reaction. Doctors use epinephrine to treat this reaction. Hereditary angioedema Your doctor may treat HAE with any of the following: anabolic steroids, or androgens antifibrinolytics C1 inhibitors, such as C1 esterase inhibitor (Berinert) or C1 esterase inhibitor (recombinant) (Ruconest) a plasma kallikrein inhibitor, such as ecallantide (Kalbitor) bradykinin receptor antagonist, such as icatibant injection (Firazyr) Tell your doctor if you have new or worsening symptoms, and follow up as necessary. Tips for relief home treatment If you have a swollen uvula or sore throat, it’s your body’s way of telling you that something is wrong. A few home remedies can help keep you strong and soothe your irritated throat. Make sure you’re getting enough fluids. If your throat hurts when you drink, try drinking small amounts throughout the day. Your urine should be light in color. If it’s dark yellow or brown, you’re not drinking enough and may be dehydrated. Additional tips include the following: Cool your throat by sucking on ice chips. Frozen juice bars or ice cream may also do the trick. Gargle with warm salt water to ease your dry, scratchy throat. Aim for a full night’s sleep, and nap during the day if you can. What’s the outlook? Outlook A swollen uvula isn’t a common occurrence. Most of the time it clears up without treatment. If you have an infection, prompt treatment should take care of the problem within a week or two. If you have allergies that lead to swelling of the uvula or throat, do your best to avoid that allergen. You should also be prepared to deal with an attack if you come into contact with the substance again. If you’ve ever had anaphylaxis, ask your doctor if you should carry injectable epinephrine (EpiPen) in case of emergency. People with HAE must learn to recognize triggers and early warning signs of an attack. Talk to your doctor about how to manage HAE.

Megacolon, as well as megarectum, is a descriptive term. It denotes dilatation of the colon that is not caused by mechanical obstruction.[1, 2] Although the definition of megacolon has varied in the literature, most researchers use the measurement of greater than 12 cm for the cecum as the standard. Because the diameter of the large intestine varies, the following definitions would also be considered: greater than 6.5 cm in the rectosigmoid region and greater than 8 cm for the ascending colon. Megacolon can be divided into the following 3 categories: Acute megacolon ( pseudo-obstruction) Chronic megacolon, which includes congenital, acquired, and idiopathic causes Toxic megacolon
Genital warts are soft growths that appear on the genitals. Genital warts are a sexually transmitted infection (STI) caused by certain strains of the human papillomavirus (HPV). These skin growths can cause pain, discomfort, and itching. They are especially dangerous for women because some types of HPV can also cause cancer of the cervix and vulva.
Deep vein thrombosis (DVT) occurs when a blood clot (thrombus) forms in one or more of the deep veins in your body, usually in your legs. Deep vein thrombosis can cause leg pain or swelling, but may occur without any symptoms. Deep vein thrombosis can develop if you have certain medical conditions that affect how your blood clots. Deep vein thrombosis can also happen if you don't move for a long time, such as after surgery, following an accident, or when you are confined to a hospital or nursing home bed. Deep vein thrombosis is a serious condition because blood clots in your veins can break loose, travel through your bloodstream and lodge in your lungs, blocking blood flow (pulmonary embolism).
A cornea transplant, also called keratoplasty, is a surgical procedure to replace part of your cornea with corneal tissue from a donor. Your cornea is the transparent, dome-shaped surface of your eye that accounts for a large part of your eye's focusing power. A cornea transplant can restore vision, reduce pain and improve the appearance of a damaged or diseased cornea. Most cornea transplant procedures are successful. But cornea transplant carries a small risk of complications, such as rejection of the donor cornea.
Carpal tunnel syndrome is a hand condition that causes numbness, tingling and other symptoms. Carpal tunnel syndrome is caused by a pinched nerve in your wrists A number of factors can contribute to carpal tunnel syndrome, including the anatomy of your wrist, certain underlying health problems and possibly patterns of hand use. Bound by bones and ligaments, the carpal tunnel is a narrow passageway located on the palm side of your wrist. This tunnel protects a main nerve to your hand and the nine tendons that bend your fingers. Compression of the nerve produces the numbness, tingling and, eventually, hand weakness that characterize carpal tunnel syndrome.
