Stroke is a medical condition in which poor blood flow to the brain results in cell death. There are two main types of stroke: ischemic, due to lack of blood flow, and hemorrhagic, due to bleeding. They result in part of the brain not functioning properly. Signs and symptoms of a stroke may include an inability to move or feel on one side of the body, problems understanding or speaking, feeling like the world is spinning, or loss of vision to one side. Signs and symptoms often appear soon after the stroke has occurred. If symptoms last less than one or two hours it is known as a transient ischemic attack (TIA) or mini- stroke. A hemorrhagic stroke may also be associated with a severe headache. The symptoms of a stroke can be permanent. Long- term complications may include pneumonia or loss of bladder control.The main risk factor for stroke is high blood pressure. Other risk factors include tobacco smoking, obesity, high blood cholesterol, diabetes mellitus, previous TIA, and atrial fibrillation. An ischemic stroke is typically caused by blockage of a blood vessel, though there are also less common causes.[1.
A hemorrhagic stroke is caused by either bleeding directly into the brain or into the space between the brain's membranes.[1. Bleeding may occur due to a ruptured brain aneurysm. Diagnosis is typically with medical imaging such as a CT scan or magnetic resonance imaging (MRI) scan along with a physical exam. Other tests such as an electrocardiogram (ECG) and blood tests are done to determine risk factors and rule out other possible causes.Low blood sugar may cause similar symptoms.Prevention includes decreasing risk factors, as well as possibly aspirin, statins, surgery to open up the arteries to the brain in those with problematic narrowing, and warfarin in those with atrial fibrillation. A stroke or TIA often requires emergency care. An ischemic stroke, if detected within three to four and half hours, may be treatable with a medication that can break down the clot. Aspirin should be used. Some hemorrhagic strokes benefit from surgery. Treatment to try to recover lost function is called stroke rehabilitation and ideally takes place in a stroke unit; however, these are not available in much of the world.In 2.

About half of people who have had a stroke live less than one year. Overall, two thirds of strokes occurred in those over 6. Classification. Strokes can be classified into two major categories: ischemic and hemorrhagic.[1. Ischemic strokes are caused by interruption of the blood supply to the brain, while hemorrhagic strokes result from the rupture of a blood vessel or an abnormal vascular structure. About 8. 7% of strokes are ischemic, the rest being hemorrhagic. Bleeding can develop inside areas of ischemia, a condition known as "hemorrhagic transformation." It is unknown how many hemorrhagic strokes actually start as ischemic strokes.Definition. In the 1. 97. 0s the World Health Organization defined stroke as a "neurological deficit of cerebrovascular cause that persists beyond 2.
This definition was supposed to reflect the reversibility of tissue damage and was devised for the purpose, with the time frame of 2. The 2. 4- hour limit divides stroke from transient ischemic attack, which is a related syndrome of stroke symptoms that resolve completely within 2. With the availability of treatments which can reduce stroke severity when given early, many now prefer alternative terminology, such as brain attack and acute ischemic cerebrovascular syndrome (modeled after heart attack and acute coronary syndrome, respectively), to reflect the urgency of stroke symptoms and the need to act swiftly.[1. Ischemic. In an ischemic stroke, blood supply to part of the brain is decreased, leading to dysfunction of the brain tissue in that area.

Advanced cardiac life support (ACLS) in adults. Literature review current through. This topic last updated. Jan 0. 3, 2. 01. 8. INTRODUCTION — The field of resuscitation has been evolving for more than two centuries . The Paris Academy of Science recommended mouth- to- mouth ventilation for drowning victims in 1. In 1. 89. 1, Dr. Friedrich Maass performed the first documented chest compressions on humans .
The American Heart Association (AHA) formally endorsed cardiopulmonary resuscitation (CPR) in 1. CPR guidelines for instruction to lay- rescuers . Advanced cardiac life support (ACLS) guidelines have evolved over the past several decades based on a combination of scientific evidence of variable strength and expert consensus. The American Heart Association (AHA) and European Resuscitation Council developed the most recent ACLS guidelines in 2.
International Liaison Committee on Resuscitation (ILCOR), and these were updated in 2. Guidelines are reviewed continually but are formally released every five years, and published in the journals Circulation and Resuscitation.
This topic will discuss the management of cardiac arrhythmias in adults as generally described in the most recent iteration of the ACLS Guidelines. Where our suggestions differ or expand upon the published guidelines, we state this explicitly. The evidence supporting the published guidelines is presented separately, as are issues related to controversial treatments for cardiac arrest patients, basic life support (BLS), airway management, and post- cardiac arrest management. See "Supportive data for advanced cardiac life support in adults with sudden cardiac arrest" and "Therapies of uncertain benefit in basic and advanced cardiac life support" and "Basic life support (BLS) in adults" and "Basic airway management in adults" and "Advanced emergency airway management in adults" and "Post- cardiac arrest management in adults".)EVIDENCE BASED GUIDELINES — Because of the nature of resuscitation research, few randomized controlled trials have been completed in humans.
Many of the recommendations in the American Heart Association and the European Resuscitation Council's 2. Guidelines for advanced cardiac life support and the 2.
ACLS Guidelines) are made based upon retrospective studies, animal studies, and expert consensus [4- 1. Guideline recommendations are classified according to the GRADE system [1. The evidence supporting the ACLS Guidelines is reviewed in detail separately. See "Supportive data for advanced cardiac life support in adults with sudden cardiac arrest".)PRINCIPLES OF MANAGEMENTExcellent basic life support and its importance — Excellent cardiopulmonary resuscitation (CPR) and early defibrillation for treatable arrhythmias remain the cornerstones of basic and ACLS. Although the 2. 01. American Heart Association (AHA) Guidelines for ACLS (ACLS Guidelines) suggest several revisions, including medications and monitoring, the emphasis on excellent CPR and its critical role in resuscitative efforts remains unchanged (algorithm 1 and algorithm 2) [5,7]. We emphasize the term "excellent CPR" because anything short of this standard does not achieve adequate cerebral and coronary perfusion, thereby compromising a patient's chances for neurologically intact survival.
CPR is discussed in detail separately; key principles in the performance of ACLS are summarized in the following table (table 1). See "Basic life support (BLS) in adults".)In the past, clinicians frequently interrupted CPR to check for pulses, perform tracheal intubation, or obtain venous access. Current ACLS Guidelines strongly recommend that every effort be made NOT to interrupt CPR; other less vital interventions (eg, tracheal intubation or administration of medications to treat arrhythmias) are made either while CPR is performed or, if a required intervention cannot be performed while CPR is in progress, during the briefest possible addition to the 2 minute rhythm check (after the completion of a full cycle of CPR). Studies in both the in- hospital and prehospital settings demonstrate that chest compressions are often performed incorrectly, inconsistently, and with excessive interruption [1.
Chest compressions must be of sufficient depth (5 to 6 cm, or 2 to 2. A single biphasic defibrillation remains the recommended treatment for ventricular fibrillation (VF) or pulseless ventricular tachycardia (VT). CPR should be performed until the defibrillator is ready for immediate discharge and resumed immediately after the shock is given, without pausing to recheck a pulse [1. Interruptions in CPR (eg, for subsequent attempts at defibrillation or pulse checks) should occur no more frequently than every 2 minutes, and for the shortest possible duration. Key elements in the performance of manual defibrillation are described in the following table (table 2).
