Electrical cardioversion is a procedure in which an electric current is used to reset the heart's rhythm back to its regular pattern (normal sinus rhythm). The low-voltage electric current enters the body through metal paddles or patches applied to the chest wall.
Coronary circulation is the circulation of blood in the blood vessels of the heart muscle (myocardium). The vessels that deliver oxygen-rich blood to the myocardium are known as coronary arteries. The vessels that remove the deoxygenated blood from the heart muscle are known as cardiac veins.
Radiosurgery: Radiosurgery devices, such as the CyberKnife Robotic Radiosurgery System, offer patients a new option for the treatment of lung cancer. The CyberKnife® System is used to treat lung cancer patients who cannot tolerate surgery, have an inoperable tumor, or are seeking an alternative to surgery.
Papillary fibroelastoma is the third most common primary tumor of the heart and is most likely to involve the cardiac valves. Like myxomas, they arise from the endocardium in most patients and since these tumors are often incidental findings at echocardiography or autopsy, the true incidence is difficult to estimate. Most patients are older than 60 years, which also contrasts with myxomas. Papillary fibroelastomas can embolize, leading to severe neurological complications and therefore, surgical removal is advised, although there is controversy regarding small incidental lesions and the need for surgery.
Shoulder dystocia is a rare emergency that can happen during the end of the second stage of labour. It's all to do with how your baby moves down through your vagina and out into the world. Shoulder dystocia happens when your baby's head has been born, but one of her shoulders becomes stuck.
Ebola virus disease (EVD; also Ebola hemorrhagic fever, or EHF), or simply Ebola, is a viral hemorrhagic fever of humans and other primates caused by ebolaviruses. Signs and symptoms typically start between two days and three weeks after contracting the virus with a fever, sore throat, muscular pain, and headaches.
Mastectomy is surgery to remove all breast tissue from a breast as a way to treat or prevent breast cancer. For those with early-stage breast cancer, mastectomy may be one treatment option. Breast-conserving surgery (lumpectomy), in which only the tumor is removed from the breast, may be another option.
A pancreas transplant is a surgical procedure to place a healthy pancreas from a deceased donor into a person whose pancreas no longer functions properly. Your pancreas is an organ that lies behind the lower part of your stomach. One of its main functions is to make insulin, a hormone that regulates the absorption of sugar (glucose) into your cells. If your pancreas doesn't make enough insulin, blood sugar levels can rise to unhealthy levels, resulting in type 1 diabetes. Most pancreas transplants are done to treat type 1 diabetes. A pancreas transplant offers a potential cure for this condition. But it is typically reserved for those with serious diabetes complications, because the side effects of a pancreas transplant are significant. In some cases, pancreas transplants may also treat type 2 diabetes. Rarely, pancreas transplants may be used in the treatment of pancreatic, bile duct or other cancers. A pancreas transplant is often done in conjunction with a kidney transplant in people whose kidneys have been damaged by diabetes.
A cricothyrotomy (also called crike, thyrocricotomy, cricothyroidotomy, inferior laryngotomy, intercricothyrotomy, coniotomy or emergency airway puncture) is an incision made through the skin and cricothyroid membrane to establish a patent airway during certain life-threatening situations, such as airway obstruction by ...
An egg cannot be fertilized when there are no sperm in the semen. The testicles continue to produce sperm, but the sperm are reabsorbed by the body. (This also happens to sperm that are not ejaculated after a while, regardless of whether you have had a vasectomy.) Sperm are made in the testicles. They pass through two tubes called the vasa deferentia to other glands and mix with seminal fluids to form semen. Vasectomy blocks each vas deferens and keeps sperm out of the seminal fluid. The sperm are absorbed by the body instead of being ejaculated.
an. 4, 2017 -- Scientists say they've identified a new organ in the body -- a swath of tissue dubbed the mesentery that connects the intestine to the abdomen and holds everything in place. For years, anatomical experts have thought the organ was composed of several different segments of tissue, as opposed to being one single structure, according to Discover magazine. Since an organ must be one structure that performs a vital function, it was not deemed worthy of organ status. But recent research from doctors at the University Hospital Limerick in Ireland shows that the mesentery is actually one single band of tissue, the magazine reported Tuesday. It begins at the pancreas and wraps around the small intestine and colon. Its purpose: to hold these organs in position so they can perform their respective functions. "Without it you can't live," lead researcher Dr. J. Calvin Coffey, a colorectal surgeon at Limerick, told the magazine. "There are no reported instances of a Homo sapien living without a mesentery." "Understanding how and why our digestive system is arranged the way it is could be crucial to our understanding of diseases like Crohn's and irritable bowel syndrome," Coffey added. "There are a lot of diseases that we are stalled on, and we need to refresh our approach to these diseases," Coffey said. "Now that we've clarified its [the mesentery's] structure, we can systematically examine it. We're at a very exciting place right now." The discovery was published recently in the Lancet Gastroenterology & Hepatology journal.
Multicystic dysplastic kidney (MCDK) is a condition that results from the malformation of the kidney during fetal development. The kidney consists of irregular cysts of varying sizes. Multicystic dysplastic kidney is a common type of renal cystic disease, and it is a cause of an abdominal mass in infants.
Physical assessment is taking an educated, systematic look at all aspects of an individual’s health status utilizing knowledge, skills and tools of health history and physical exam. To collect data- information about the client’s health, including physiological, psychological, sociocultural and spiritual aspects To establish actual and potential problems To establish the nurse-client relationship Method: The history is done first, then the physical examination focuses on finding data associated with the history. Health History- obtained through interview and record review. Physical exam- accomplished by tools and techniques ** A complete assessment is not necessarily carried out each time. A comprehensive assessment is part of a health screening examination. On admission, you will do an admission assessment (not necessarily including everything presented here) and document it on the admission form. You will do a daily shift assessment (patient systems review). And, if client has a specific problem, you may assess only that part of the body (focused). Data Collection: Information is organized into objective and subjective data: Subjective: Apparent only to person affected; includes client’s perceptions, feelings, thoughts, and expectations. It cannot be directly observed and can be discovered only asking questions. Objective: Detectable by an observer or can be tested against an acceptable standard; tangible, observable facts; includes observation of client behavior, medical records, lab and diagnostic tests, data collected by physical exam. ** To obtain data for the nursing health history, you must utilize good interview techniques and communications skills. Record accurately. DO NOT ASSUME. D. Frameworks for Health Assessment There are two main frameworks utilized in health assessment: Head to Toe- systematic collection of data starting with the head and working downward. Functional Health Assessment- Gordon’s 11 functional health patterns that address the behaviors a person uses to maintain health. PERSON is the ACC-ADN framework for assessment. It is similar to Gordon's functional health patterns.
Pericardiocentesis is the aspiration of fluid from the pericardial space that surrounds the heart. This procedure can be life saving in patients with cardiac tamponade, even when it complicates acute type A aortic dissection and when cardiothoracic surgery is not available. [1] Cardiac tamponade is a time sensitive, life-threatening condition that requires prompt diagnosis and management. Historically, the diagnosis of cardiac tamponade has been based on clinical findings. Claude Beck, a cardiovascular surgeon, described 2 triads of clinical findings that he found associated with acute and chronic cardiac tamponade. The first of these triads consisted of hypotension, an increased venous pressure, and a quiet heart. It has come to be recognized as Beck's triad, a collection of findings most commonly produced by acute intrapericardial hemorrhage. Subsequent studies have shown that these classic findings are observed in only a minority of patients with cardiac tamponade. [2] The detection of pericardial fluid has been facilitated by the development and continued improvement of echocardiography. [3] Cardiac ultrasound is now accepted as the criterion standard imaging modality for the assessment of pericardial effusions and the dynamic findings consistent with cardiac tamponade. With echocardiography, the location of the effusion can be identified, the size can be estimated (small, medium, or large), and the hemodynamic effects can be examined by assessing for abnormal septal motion, right atrial or right ventricular inversion, and decreased respiratory variation of the diameter of the inferior vena cava.
What is systemic lupus erythematosus? The immune system normally fights off dangerous infections and bacteria to keep the body healthy. An autoimmune disease occurs when the immune system attacks the body because it confuses it for something foreign. There are many autoimmune diseases, including systemic lupus erythematosus (SLE). The term lupus has been used to identify a number of immune diseases that have similar clinical presentations and laboratory features, but SLE is the most common type of lupus. People are often referring to SLE when they say lupus.
