Stab Wound
A stab wound is a specific form of penetrating trauma to the skin that results from a knife or a similar pointed object. While stab wounds are typically known to be caused by knives, they can also occur from a variety of implements, including broken bottles and ice picks. Most stabbings occur because of intentional violence or through self-infliction. The treatment is dependent on many different variables such as the anatomical location and the severity of the injury. Even though stab wounds are inflicted at a much greater rate than gunshot wounds, they account for less than 10% of all penetrating trauma deaths. Management Stab wounds can result in various internal and external injuries. These wounds are typically caused by low-velocity weapons, meaning the damage is usually confined to the weapon's path, unlike gunshot wounds which often affect surrounding tissues. The abdomen is the most commonly injured area in cases of stab wounds. Interventions that may be needed depending ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jereboam O
Jeroboam I (; Hebrew: ''Yārŏḇʿām''; ), frequently cited Jeroboam son of Nebat, was, according to the Hebrew Bible, the first king of the northern Kingdom of Israel following a revolt of the ten tribes against Rehoboam that put an end to the United Monarchy. According to the book of 1 Kings, he reigned for 22 years and "there was war continually between Rehoboam and Jeroboam". Jeroboam also fought Abijam son of Rehoboam king of Judah. Jeroboam is often described as "doing evil in the sight of the Lord" William F. Albright has dated his reign from 922 to 901 BC, while Edwin R. Thiele offers the dates 931 to 910 BC. There has been much academic discussion in recent years on whether Jeroboam I existed and whether he may be a retrojection of Jeroboam II, though there is not a consensus on the topic. Etymology The name ''Yārŏḇ‘ām'' is commonly held to have been derived from ''rīḇ'' and ''ʿam'' , signifying "the people contend" or "he pleads the people's cause" ...

Hemorrhage
Bleeding, hemorrhage, haemorrhage or blood loss, is blood escaping from the circulatory system from damaged blood vessels. Bleeding can occur internally, or externally either through a natural opening such as the mouth, nose, ear, urethra, vagina, or anus, or through a puncture in the skin. Hypovolemia is a massive decrease in blood volume, and death by excessive loss of blood is referred to as exsanguination. Typically, a healthy person can endure a loss of 10–15% of the total blood volume without serious medical difficulties (by comparison, blood donation typically takes 8–10% of the donor's blood volume). The stopping or controlling of bleeding is called hemostasis and is an important part of both first aid and surgery. Types * Upper head ** Intracranial hemorrhage — bleeding in the skull. ** Cerebral hemorrhage — a type of intracranial hemorrhage, bleeding within the brain tissue itself. ** Intracerebral hemorrhage — bleeding in the brain caused by th ...

Surgical
Surgery is a medical specialty that uses manual and instrumental techniques to diagnose or treat pathological conditions (e.g., trauma, disease, injury, malignancy), to alter bodily functions (e.g., malabsorption created by bariatric surgery such as gastric bypass), to reconstruct or alter aesthetics and appearance ( cosmetic surgery), or to remove unwanted tissues (body fat, glands, scars or skin tags) or foreign bodies. The act of performing surgery may be called a surgical procedure or surgical operation, or simply "surgery" or "operation". In this context, the verb "operate" means to perform surgery. The adjective surgical means pertaining to surgery; e.g. surgical instruments, surgical facility or surgical nurse. Most surgical procedures are performed by a pair of operators: a surgeon who is the main operator performing the surgery, and a surgical assistant who provides in-procedure manual assistance during surgery. Modern surgical operations typically require a surgi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liver Function Tests
Liver function tests (LFTs or LFs), also referred to as a hepatic panel or liver panel, are groups of blood tests that provide information about the state of a patient's liver. These tests include prothrombin time (PT/INR), activated partial thromboplastin time (aPTT), albumin, bilirubin (direct and indirect), and others. The liver transaminases aspartate transaminase (AST or SGOT) and alanine transaminase (ALT or SGPT) are useful biomarkers of liver injury in a patient with some degree of intact liver function. Most liver diseases cause only mild symptoms initially, but these diseases must be detected early. Hepatic (liver) involvement in some diseases can be of crucial importance. This testing is performed on a patient's blood sample. Some tests are associated with functionality (e.g., albumin), some with cellular integrity (e.g., transaminase), and some with conditions linked to the biliary tract ( gamma-glutamyl transferase and alkaline phosphatase). Because some of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White Blood Cell Count
A complete blood count (CBC), also known as a full blood count (FBC) or full haemogram (FHG), is a set of medical laboratory tests that provide cytometry, information about the cells in a person's blood. The CBC indicates the counts of white blood cells, red blood cells and platelets, the concentration of hemoglobin, and the hematocrit (the volume percentage of red blood cells). The red blood cell indices, which indicate the average size and hemoglobin content of red blood cells, are also reported, and a white blood cell differential, which counts the different types of white blood cells, may be included. The CBC is often carried out as part of a medical assessment and can be used to monitor health or diagnose diseases. The results are interpreted by comparing them to Reference ranges for blood tests, reference ranges, which vary with sex and age. Conditions like anemia and thrombocytopenia are defined by abnormal complete blood count results. The red blood cell indices can provi ...

Hematocrit
The hematocrit () (Ht or HCT), also known by several other names, is the volume percentage (vol%) of red blood cells (RBCs) in blood, measured as part of a blood test. The measurement depends on the number and size of red blood cells. It is normally 40.7–50.3% for males and 36.1–44.3% for females. It is a part of a person's complete blood count results, along with hemoglobin concentration, white blood cell count and platelet count. Because the purpose of red blood cells is to transfer oxygen from the lungs to body tissues, a blood sample's hematocrit—the red blood cell volume percentage—can become a point of reference of its capability of delivering oxygen. Hematocrit levels that are too high or too low can indicate a blood disorder, dehydration, or other medical conditions. An abnormally low hematocrit may suggest anemia, a decrease in the total amount of red blood cells, while an abnormally high hematocrit is called polycythemia. Both are potentially life-threatening d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hypovolemia
Hypovolemia, also known as volume depletion or volume contraction, is a state of abnormally low extracellular fluid in the body. This may be due to either a loss of both salt and water or a decrease in blood volume. Hypovolemia refers to the loss of extracellular fluid and should not be confused with dehydration. Hypovolemia is caused by a variety of events, but these can be simplified into two categories: those that are associated with Renal physiology, kidney function and those that are not. The signs and symptoms of hypovolemia worsen as the amount of fluid lost increases. Immediately or shortly after mild fluid loss (from blood donation, diarrhea, vomiting, bleeding from trauma, etc.), one may experience headache, fatigue, weakness, dizziness, or thirst. Untreated hypovolemia or excessive and rapid losses of volume may lead to hypovolemic shock. Signs and symptoms of hypovolemic shock include Tachycardia, increased heart rate, Hypotension, low blood pressure, Pallor, pale or c ...

Contrast Medium
A contrast agent (or contrast medium) is a substance used to increase the contrast of structures or fluids within the body in medical imaging. Contrast agents absorb or alter external electromagnetism or ultrasound, which is different from radiopharmaceuticals, which emit radiation themselves. In X-ray imaging, contrast agents enhance the radiodensity in a target tissue or structure. In magnetic resonance imaging (MRI), contrast agents shorten (or in some instances increase) the relaxation times of nuclei within body tissues in order to alter the contrast in the image. Contrast agents are commonly used to improve the visibility of blood vessels and the gastrointestinal tract. The types of contrast agent are classified according to their intended imaging modalities. Radiocontrast media For radiography, which is based on X-rays, iodine and barium are the most common types of contrast agent. Various sorts of iodinated contrast agents exist, with variations occurring between the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computed Tomography
A computed tomography scan (CT scan), formerly called computed axial tomography scan (CAT scan), is a medical imaging technique used to obtain detailed internal images of the body. The personnel that perform CT scans are called radiographers or radiology technologists. CT scanners use a rotating X-ray tube and a row of detectors placed in a gantry to measure X-ray attenuations by different tissues inside the body. The multiple X-ray measurements taken from different angles are then processed on a computer using tomographic reconstruction algorithms to produce tomographic (cross-sectional) images (virtual "slices") of a body. CT scans can be used in patients with metallic implants or pacemakers, for whom magnetic resonance imaging (MRI) is contraindicated. Since its development in the 1970s, CT scanning has proven to be a versatile imaging technique. While CT is most prominently used in medical diagnosis, it can also be used to form images of non-living objects. The 1979 N ...

Diagnostic Peritoneal Lavage
Diagnostic peritoneal lavage (DPL) or diagnostic peritoneal aspiration (DPA) is a surgical diagnostic procedure to determine if there is free floating fluid (most often blood) in the abdominal cavity. Indications This procedure is performed when intra-abdominal bleeding ( hemoperitoneum), usually secondary to trauma, is suspected. In a hemodynamically unstable patient with high-risk mechanism of injury, peritoneal lavage is a means of rapidly diagnosing intra-abdominal injury requiring laparotomy, but has largely been replaced in trauma care by the use of a focused assessment with sonography for trauma (FAST scan) due to its repeatability, non-invasiveness and non-interference with subsequent computed tomography (CT scan). Abdominal CT and contrast duodenography may complement lavage in stable patients, but in an unstable or uncooperative persons, these studies are too time-consuming or require ill-advised sedation. Magnetic resonance imaging is extremely accurate for the anatom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Focused Assessment With Sonography For Trauma
Focused assessment with sonography in trauma (commonly abbreviated as FAST) is a rapid bedside ultrasound examination performed by surgeons, emergency physicians, and paramedics as a screening test for blood around the heart (pericardial effusion) or abdominal organs ( hemoperitoneum) after trauma. There is also the extended FAST (eFAST) which includes some additional ultrasound views to assess for pneumothorax. It may be useful prior to conducting more accurate tests such as CT in a stable trauma patient. The four classic areas that are examined for free fluid are the perihepatic space (including Morison's pouch or the hepatorenal recess), peri splenic space, pericardium, and the pelvis. With this technique it is possible to identify the presence of moderate to large amounts of intraperitoneal or pericardial free fluid. In the context of traumatic injury, this fluid will usually be due to bleeding. FAST is poor at detecting smaller amounts of free fluid. Indications Reas ...

Trauma Center
A trauma center, or trauma centre, is a hospital equipped and staffed to provide care for patients suffering from major traumatic injuries such as falls, motor vehicle collisions, or gunshot wounds. The term "trauma center" may be used incorrectly to refer to an emergency department (also known as a "casualty department" or "accident and emergency") that lacks the presence of specialized services or certification to care for victims of major trauma. In the United States, a hospital can receive trauma center status by meeting specific criteria established by the American College of Surgeons (ACS) and passing a site review by the Verification Review Committee. Official designation as a trauma center is determined by individual state law provisions. Trauma centers vary in their specific capabilities and are identified by "Level" designation, Level I (Level-1) being the highest and Level III (Level-3) being the lowest (some states have four or five designated levels).
