Venipuncture: Butterfly Method
Venipuncture: Butterfly Method Mohamed Ibrahim 27,104 Views • 2 years ago

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.

Barrett esophagus Therapy
Barrett esophagus Therapy samer kareem 3,564 Views • 2 years ago

Barrett's esophagus is a complication of chronic (long lasting) and usually severe gastrointestinal reflux disease (GERD), but occurs in only a small percentage of patients with GERD. Criteria are needed for screening patients with GERD for Barrett's esophagus. Until validated criteria are available, it seems reasonable to do screening endoscopies in GERD patients who cannot be taken off acid suppression therapy after two to three years. The diagnosis of Barrett's esophagus rests upon seeing (at endoscopy) a pink esophageal lining that extends a short distance (usually less than 2.5 inches) up the esophagus from the gastroesophageal junction and finding intestinal type cells (goblet cells) on biopsy of the lining. There is a small but definite increased risk of cancer of the esophagus (adenocarcinoma) in patients with Barrett's esophagus.

Large Pulmonary Clot Removal samer kareem 2,369 Views • 2 years ago

The removal of a clot is called an embolectomy. An embolectomy might be done during a surgery. Or it might be done with a minimally invasive procedure that uses a catheter (a thin tube that is guided through a blood vessel). This type of treatment for pulmonary embolism is used only in rare cases.

Abscess On Side Of Nose
Abscess On Side Of Nose samer kareem 2,688 Views • 2 years ago

An abscess is a collection of pus. Pus is a thick fluid that usually contains white blood cells, dead tissue and germs (bacteria). The usual cause of an abscess is an infection with bacteria. Certain bacteria are more likely to be 'pus-forming' as they make chemicals (toxins) that can damage the body's tissues.

heart failure
heart failure samer kareem 2,149 Views • 2 years ago

Heart failure, sometimes known as congestive heart failure, occurs when your heart muscle doesn't pump blood as well as it should. Certain conditions, such as narrowed arteries in your heart (coronary artery disease) or high blood pressure, gradually leave your heart too weak or stiff to fill and pump efficiently. Not all conditions that lead to heart failure can be reversed, but treatments can improve the signs and symptoms of heart failure and help you live longer. Lifestyle changes — such as exercising, reducing salt in your diet, managing stress and losing weight — can improve your quality of life. One way to prevent heart failure is to control conditions that cause heart failure, such as coronary artery disease, high blood pressure, diabetes or obesity.

Suprapatellar Tibial Intramedullary Rod Surgery
Suprapatellar Tibial Intramedullary Rod Surgery samer kareem 10,158 Views • 2 years ago

Intramedullary nailing of the tibia with suprapatellar entry and semi-extended positioning makes it technically easier to nail the proximal and distal fractures. The purpose of this article was to describe a simple method for suprapatellar nailing (SPN). A step-by-step run through of the surgical technique is described, including positioning of the patient. There are as yet only a few clinical studies that illustrate the complications with this method, and there has been no increased frequency of intraarticular damage. Within the body of the manuscript, information is included about intraarticular damage and comments with references about anterior knee pain.

Respiratory Syncytial Virus
Respiratory Syncytial Virus samer kareem 2,084 Views • 2 years ago

Respiratory syncytial virus (RSV) is a virus that causes infections of the lungs and respiratory tract. It's so common that most children have been infected with the virus by age 2. Respiratory syncytial (sin-SISH-ul) virus can also infect adults. In adults and older, healthy children, the symptoms of respiratory syncytial virus are mild and typically mimic the common cold. Self-care measures are usually all that's needed to relieve any discomfort. Infection with respiratory syncytial virus can be severe in some cases, especially in premature babies and infants with underlying health conditions. RSV can also become serious in older adults, adults with heart and lung diseases, or anyone with a very weak immune system (immunocompromised).

Ventricular septal defect (VSD)
Ventricular septal defect (VSD) samer kareem 3,261 Views • 2 years ago

A ventricular septal defect (VSD), a hole in the heart, is a common heart defect that's present at birth (congenital). The hole occurs in the wall that separates the heart's lower chambers (septum) and allows blood to pass from the left to the right side of the heart. The oxygen-rich blood then gets pumped back to the lungs instead of out to the body, causing the heart to work harder. A small ventricular septal defect may cause no problems, and many small VSDs close on their own. Larger VSDs need surgical repair early in life to prevent complications.

Guillain-Barre syndrome is a rare disorder in which your body's immune system attacks your nerves. Weakness and tingling in your extremities are usually the first symptoms. These sensations can quickly spread, eventually paralyzing your whole body. In its most severe form Guillain-Barre syndrome is a medical emergency. Most people with the condition must be hospitalized to receive treatment. The exact cause of Guillain-Barre syndrome is unknown. But it is often preceded by an infectious illness such as a respiratory infection or the stomach flu. There's no known cure for Guillain-Barre syndrome, but several treatments can ease symptoms and reduce the duration of the illness. Most people recover from Guillain-Barre syndrome, though some may experience lingering effects from it, such as weakness, numbness or fatigue.

Digoxin Toxicity
Digoxin Toxicity samer kareem 1,887 Views • 2 years ago

The incidence of digitalis toxicity has declined in recent years, due to decreased use of this drug along with improved technology for monitoring of drug levels and increased awareness of drug interactions. Nevertheless, cardiac glycoside toxicity continues to be a problem in the United States because of the wide use of digoxin (a preparation of digitalis) and its narrow therapeutic window. Digitalis is a plant-derived cardiac glycoside commonly used in the treatment of chronic heart failure (CHF), atrial fibrillation, and reentrant supraventricular tachycardia.[1, 2] Digoxin is the only available preparation of digitalis in the United States. (See Etiology and Epidemiology.) Cardiac glycosides are found in certain flowering plants, such as oleander and lily-of-the-valley. Indigenous people in various parts of the world have used many plant extracts containing cardiac glycosides as arrow and ordeal poisons. The ancient Egyptians used squill (Urginea maritime) as a medicine. The Romans employed it as a diuretic, heart tonic, emetic, and rat poison. Digitalis, or foxglove, was mentioned in the year 1250 in the writings of Welsh physicians. Fuchsius described it botanically 300 years later and named it Digitalis purpurea. William Withering published his classic account of foxglove and some of its medical uses in 1785, remarking upon his experience with digitalis. He recognized many of the signs of digitalis toxicity, noting, "The foxglove, when given in very large and quickly repeated doses, occasions sickness, vomiting, purging, giddiness, confused vision, objects appearing green or yellow; increased secretion of urine, slow pulses, even as low as 35 in a minute, cold sweats, convulsions, syncope, death." (See Presentation and Workup.) During the early 20th century, as a result of the work of Cushny, Mackenzie, Lewis, and others, the drug was gradually recognized as specific for treatment of atrial fibrillation. Only subsequently was the value of digitalis for treatment of CHF established. Cardiac glycosides enhance cardiac contractility and slow conduction through the atrioventricular (AV) junction by increasing vagal tone.[3] (See Etiology.) Cardiac glycoside toxicity has been known to result from ingestion of some plants, including yellow oleander (Thevetia peruviana) and foxglove, and a similar toxidrome has been associated with the use of herbal dietary supplements that contain cardiac glycosides. Digoxin is among the top 50 prescribed drugs in the United States.[4] In 2011, the American Association of Poison Control Centers reported 1601 single exposures to cardiac glycoside drugs.[5] Cardiac glycosides account for 2.6% of toxic plant exposures in the United States.[6, 7] Most of these exposures are in children.[7] (See Epidemiology.) Digoxin-specific fragment antigen-binding (Fab) antibody fragments have contributed significantly to the improved morbidity and mortality of toxic patients since their approval in 1986 by the US Food and Drug Administration (FDA).
