Hospitals: Stroke Prevention Strategies And Best Practices

Stroke is a life-threatening medical condition that requires immediate attention. It occurs when a clot or burst blood vessel blocks blood flow to the brain, causing brain cells to die and leading to potential permanent brain damage or death. The key to effective stroke treatment and recovery is getting to the hospital quickly, as every second counts. Hospitals can play a crucial role in preventing strokes and improving patient outcomes. They can achieve this through prompt diagnosis, treatment, and rehabilitation.

Hospitals are equipped with emergency medical services (EMS) that can be activated by calling 911. EMS staff can begin life-saving treatments while en route to the hospital, improving the chances of recovery. Once at the hospital, patients may receive emergency care, treatment to prevent another stroke, and rehabilitation to address the side effects. Brain scans help determine the type of stroke, and specialized doctors, such as neurologists and neurosurgeons, may be involved in patient care.

Additionally, hospitals can help prevent strokes by identifying and managing risk factors. This includes controlling blood pressure, managing cholesterol and weight, encouraging healthy lifestyle choices such as regular exercise and a balanced diet, and treating underlying conditions like atrial fibrillation and high blood sugar. Hospitals also play a crucial role in patient education, empowering individuals to recognize stroke symptoms and seek immediate medical attention.

Overall, hospitals have the necessary tools, expertise, and emergency protocols to prevent strokes, provide timely treatment, and support patients' recovery and rehabilitation.

Hospitals can administer acute stroke medications to prevent strokes

Stroke is a leading cause of death and disability in the United States. It occurs when a clot or burst blood vessel blocks blood flow to the brain, causing brain cells to die. Every minute that passes increases the risk of permanent brain damage or death. Therefore, it is crucial to seek immediate medical attention if stroke symptoms are suspected.

One such thrombolytic drug is recombinant tissue plasminogen activator (tPA), which must be given to patients within 3 to 4.5 hours of the onset of stroke symptoms. tPA has been shown to increase the probability of recovering with little or no deficit after a stroke.

In addition to tPA, other acute stroke medications include:

• Anticonvulsants: Seizures associated with stroke can be life-threatening, and benzodiazepines such as diazepam and lorazepam are often used as first-line drugs to control them.
• Antiplatelet agents: While these drugs have not been shown to treat acute ischemic stroke, they can help prevent recurrent strokes. Aspirin, for example, blocks prostaglandin synthetase, inhibiting platelet aggregation.
• Anticoagulants: These drugs, such as warfarin, are used for secondary stroke prevention by reducing the risk of blood clots.
• Beta-blockers and calcium channel blockers: These medications are used to manage blood pressure in acute stroke patients, as high blood pressure is a risk factor for stroke.

Hospitals can treat strokes with surgery to remove blood clots

Hospitals can prevent strokes from causing permanent damage by administering treatment to clear blockages and restore blood flow to the brain. This treatment must be given within a few hours of the onset of stroke symptoms.

A stroke, or "brain attack", occurs when a blood clot or burst blood vessel blocks blood flow to the brain. When brain tissue doesn't receive proper blood flow, brain cells begin to die, affecting movement, speech, and thinking. Therefore, timely treatment is crucial to prevent permanent brain damage or even death.

One surgical procedure to treat strokes is a thrombectomy, which involves inserting a catheter into an artery to access and remove a blood clot. This procedure can restore blood flow and help prevent or minimize damage to vital organs and nearby tissue. The American Stroke Association (ASA) recommends that a thrombectomy be performed within 16 hours of a person experiencing a stroke, and ideally within a 6-hour window from the onset of symptoms.

The steps of a thrombectomy are as follows:

• Preparation and medication: The patient changes into a hospital gown and receives IV fluids.
• Anesthetic: A local anesthetic is administered to numb the access site so that the patient does not feel the incision, which is commonly made in the groin, neck, or arm.
• Clot removal: A surgeon threads a stent retriever through the catheter and guides it to the blockage. After the stent captures the clot, the surgeon pulls it out.
• Stent placement: The surgeon pushes through the clot to keep the artery open and places the stent.
• Closing and cleaning: The surgeon removes the tools, closes the blood vessel, and stitches or bandages the incision site.

After a thrombectomy, patients are monitored in a recovery room and may need to stay in the hospital overnight or longer. Doctors may prescribe blood thinners and thrombolytics (clot-dissolving drugs) to prevent future clots and break up any remaining fragments.

Hospitals can treat hemorrhagic strokes with endovascular procedures

Endovascular management of hemorrhagic strokes has evolved significantly with advancements in tools, devices, and techniques. The introduction of Guglielmi detachable coils in the early 1990s revolutionized the field, and endovascular therapy quickly gained popularity over open surgery. Since then, stent-assisted coiling and balloon remodeling techniques have been developed to improve the durability of treatment for wide-necked aneurysms.

One of the key advantages of endovascular treatment is the ability to occlude the aneurysm while preserving blood flow through the parent artery. This constructive approach is the most common and preferred technique for treating aneurysms. However, in some cases, a deconstructive approach may be necessary, where the aneurysm and its parent artery are obliterated.

Hospitals play a crucial role in the treatment of hemorrhagic strokes, and endovascular procedures have become an essential tool in their arsenal. These procedures offer improved safety and outcomes compared to surgical clipping, particularly for ruptured aneurysms. Additionally, endovascular therapy can be used as a first-line treatment for intracranial aneurysms and other vascular malformations.

It is important to recognize the warning signs of a stroke, such as sudden numbness or weakness on one side of the body, trouble speaking or understanding others, and sudden vision problems. If these symptoms occur, immediate medical attention is crucial as time is of the essence in stroke treatment.

Hospitals can treat hemorrhagic strokes with surgery to stop bleeding

A hemorrhagic stroke is a life-threatening condition that requires immediate medical attention. It occurs when a blood vessel in the brain ruptures and bleeds, disrupting normal circulation and causing blood loss to the surrounding areas. The bleeding also puts pressure on the brain, which can result in severe symptoms that get worse quickly and lead to permanent brain damage or even death.

Hospitals can treat hemorrhagic strokes with surgery to stop the bleeding. The two main treatments for hemorrhagic strokes are medications and surgery. Doctors will first attempt to control the bleeding using medications to reduce blood pressure or slow down the bleeding. They may also administer clotting medications to increase the body's ability to stop the bleeding.

However, for more severe strokes, surgery may be necessary to repair the ruptured blood vessel and stop the bleeding. This involves removing the accumulated blood to relieve the pressure buildup on the brain. Surgery may also be required to relieve pressure caused by bleeding and brain swelling.

After the hemorrhagic stroke is brought under control, doctors may provide supportive care, such as intravenous (IV) fluids and management of other medical problems. The patient will also require stroke rehabilitation, including speech therapy, physical therapy, occupational therapy, and cognitive therapy, to help adjust to changes in brain and body functions.

It is crucial to recognize the symptoms of a hemorrhagic stroke and seek immediate medical attention to improve the chances of a positive outcome. Symptoms may include sudden and severe headaches, weakness or numbness on one side of the body, problems with speech or swallowing, and confusion or disorientation.

Hospitals can provide stroke rehabilitation to help patients regain their independence

While hospitals can administer acute stroke medications to try to stop a stroke while it is happening, they can also provide stroke rehabilitation to help patients regain their independence. Stroke rehabilitation should start in the hospital as soon after the stroke as possible. This is because stroke rehabilitation is a critical measure to reduce disability and improve the quality of life, and it is an integral part of the treatment system for cerebrovascular disease.

In some cases, brain cell damage may be temporary and may resume functioning over time. In other cases, the brain can reorganize its own functioning, and a region of the brain "takes over" for a region damaged by the stroke. Rehabilitation rates are encouraging, with more than two-thirds of stroke survivors in the U.S. receiving rehabilitation services after hospitalization.

A study in Shanghai, China, found that a three-level stroke rehabilitation service system improved the efficiency of daily work, improved the clinical outcomes of stroke patients, and increased patient satisfaction. This system included primary rehabilitation for acute and sub-acute stroke rehabilitation in tertiary hospitals or tertiary rehabilitation hospitals, secondary rehabilitation for the convalescent phase of stroke in secondary hospitals, and tertiary rehabilitation for the chronic phase of stroke in community health service centers or township health centers or families.

Another study found that a regional three-level rehabilitation network improved the self-care ability and quality of life of stroke patients. This network included acute, convalescent, and chronic phases of rehabilitation.
