Stroke Treatment: Hospital Care And Recovery

Stroke treatment in a hospital setting is a multifaceted and urgent process involving various medical professionals and interventions. The primary goal is to address the blockage or bleeding causing the stroke and stabilize the patient, often through emergency care in a specialized stroke unit. Treatment options include medications such as blood-thinning drugs and thrombolytics, surgical procedures like thrombectomies and angioplasties, and supportive care such as breathing support and rehabilitation. The type of treatment depends on the type of stroke, the time elapsed since symptom onset, and the patient's overall health condition. Recognizing stroke symptoms and seeking immediate medical attention are crucial for optimizing treatment outcomes and preventing long-term disabilities or fatalities.

Thrombolysis to get rid of blood clots

Thrombolysis is a treatment method used in hospitals to get rid of blood clots in the brain and restore blood flow after a stroke. This procedure is typically administered within the first 24 hours after a stroke and involves the use of thrombolytic drugs, also known as "clot-busting" drugs. These drugs work by dissolving blood clots that have formed in the brain, preventing further damage and improving the chances of recovery.

Thrombolytic drugs, such as alteplase, recombinant tissue plasminogen activator (rt-PA), and tissue plasminogen activator (tPA), are effective in breaking up blood clots and improving blood flow to the affected areas of the brain. Clinical trials have shown that these drugs can significantly enhance the chances of recovering from a stroke and reduce long-term disabilities. Patients treated with thrombolysis are also less likely to require long-term care in nursing homes.

However, it is important to note that thrombolytic therapy also carries risks. One of the major concerns is the potential for serious bleeding in the brain, which can be fatal. As a result, there are strict time constraints on when these drugs can be administered, usually within three hours of the onset of stroke symptoms, and an upper age limit of 80 years in some countries. Additionally, thrombolysis may not be suitable for all types or grades of stroke severity.

The decision to administer thrombolysis is made by medical professionals, including neurologists and neurosurgeons, based on the patient's individual circumstances and the time since the stroke occurred. It is crucial to recognise the signs and symptoms of a stroke and seek immediate medical attention by calling an ambulance. The prompt treatment of strokes, including thrombolysis, plays a vital role in improving patient outcomes and reducing the risk of long-term disabilities or death.

Thrombectomy to remove blood clots

When a person has a stroke, it is imperative that they receive medical attention as soon as possible. Calling an ambulance is crucial as medical staff can begin life-saving treatment en route to the hospital. In-hospital treatment for stroke patients may include emergency care, medication to prevent another stroke, and rehabilitation to treat side effects.

One such treatment is thrombectomy, a surgical procedure to remove blood clots from arteries or veins. Thrombectomy can be performed as emergency treatment to quickly restore blood flow to vital organs, including the brain, thereby reducing the risk of permanent disability or death.

There are two main types of thrombectomy: surgical thrombectomy and mechanical thrombectomy. During a surgical thrombectomy, an incision is made to access the blocked blood vessel, which is then cut open to remove the clot using a balloon, after which the vessel is repaired. Mechanical thrombectomy, on the other hand, involves inserting special devices through catheters to macerate or suction out clots.

The type of thrombectomy performed depends on the location and extent of the blood clot. For instance, a clot in a very small blood vessel or an area that is hard to reach may not be suitable for thrombectomy. Additionally, the patient's general health, the duration of the clot, and its location in the body are all factors that influence the suitability of the procedure.

Before the procedure, patients are typically administered medicine to prevent new clots from forming, such as blood thinners like heparin, and are given anesthesia or sedation to ensure comfort during the surgery.

Surgery to relieve pressure in the skull

A stroke, sometimes called a "brain attack", occurs when something blocks the blood supply to the brain or when a blood vessel in the brain bursts. This can lead to brain damage, long-term disability, or even death. One of the treatments for stroke in a hospital is surgery to relieve pressure in the skull, also known as a craniectomy or craniotomy.

A craniectomy is a type of brain surgery that relieves pressure on the brain by removing a piece of the skull. This procedure is often performed as an emergency and can be life-saving. The surgeon makes an incision in the scalp, usually on the side of the skull with the most pressure, and moves away the surrounding tissue. Then, they use a drill and saw to remove a portion of the skull, creating space for extra fluid or inflammation. The removed piece of skull is either stored in a freezer or the patient's abdomen, or it may be discarded. The surgeon may then place a mesh piece (artificial dura) over the brain to protect it.

After the craniectomy, the patient will need plenty of rest and must keep their head upright. They will also need to wear a helmet to protect their skull. The patient's care team will provide instructions and assistance during their hospital stay and prepare them for their return home. Follow-up appointments are necessary to ensure proper healing, and rehabilitation may be required for months to years after the surgery.

It is important to note that craniectomy surgery has risks, including the possibility of coma and death. The healthcare provider will carefully monitor the patient's symptoms and the pressure inside their skull before recommending this procedure. The decision to proceed with surgery is made when the benefits are believed to outweigh the risks.

A craniotomy, on the other hand, is a similar procedure where a portion of the skull is temporarily removed and then replaced after the brain surgery is completed. This technique may involve the use of computers and imaging scans, such as MRI or CT scans, to precisely locate the area of the brain that requires treatment.

Rehabilitation to ease the transition home

Rehabilitation after a stroke often begins in the hospital, usually within a day or two. The rehabilitation process helps to ease the transition from hospital to home and can help prevent another stroke. The recovery time after a stroke is different for each individual and can take weeks, months, or even years. Some people recover fully, but others may have long-term or lifelong disabilities.

Before leaving the hospital, a patient's provider will test how well they can speak, swallow, and walk. The patient will then work with their provider to set recovery goals and expectations that fit their unique health situation. Rehab can include physical therapy, occupational therapy, and speech therapy. It is important to attend rehab and other therapy appointments and to inform therapists of any discomfort or pain.

In addition to rehabilitation, medication and surgery may be used to treat the medical conditions that lead to a stroke. A patient's doctor may prescribe blood-thinning drugs (anticoagulants) or antiplatelet drugs, such as aspirin or clopidogrel. Surgery may also be performed to prevent a recurrence of a stroke. Surgical techniques include carotid endarterectomy, carotid angioplasty and stenting, and endovascular therapy.

It is important to note that stroke patients are at high risk for another stroke, with 1 in 4 stroke survivors experiencing another stroke within 5 years. Therefore, it is crucial to work with a healthcare team to prevent or treat the medical conditions that lead to strokes and to make any necessary lifestyle changes, such as changes to diet and exercise habits.

tPA to break up blood clots

When a person experiences a stroke, time is of the essence to prevent lasting brain damage, long-term disability, or death. If a patient arrives at the hospital within three hours of the onset of symptoms, they may be eligible for a thrombolytic drug called tPA, which stands for tissue plasminogen activator. tPA is a clot-busting medication that can break up blood clots and restore blood flow to the brain.

TPA is a thrombolytic drug that works by activating the enzyme plasminogen and converting it into plasmin. Plasmin breaks down the links between fibrin molecules in blood clots, effectively dissolving them. This process helps to restore blood flow to the brain, which is crucial in the event of an ischemic stroke, the most common type of stroke.

To determine if a patient is eligible for tPA treatment, doctors will assess their neurological deficits and perform a CT scan to ensure the stroke is ischemic. tPA is only used for ischemic strokes and is not indicated for hemorrhagic strokes, which involve bleeding into the brain. Several conditions may also make a person ineligible for tPA treatment, including recent head trauma, bleeding disorders, or uncontrolled hypertension. The most common side effect of tPA is bleeding due to its ability to break down blood clots and disrupt platelet bonds.

While tPA is most effective on smaller blood clots, some patients with larger blockages may still benefit from its use. In these cases, tPA can be administered in conjunction with mechanical thrombectomy, a procedure where a device is threaded through an artery to grab and remove the clot. tPA can also be used as a bridge therapy while awaiting mechanical thrombectomy, extending the therapeutic window for treatment.

The timely administration of tPA is critical to its effectiveness. It works best when given within 90 minutes to 3 hours of stroke onset. However, some hospitals may not be equipped with the necessary resources and specialists to rapidly evaluate and treat patients with tPA. Despite this, studies have shown that tPA improves the chances of recovering from an ischemic stroke and reduces the likelihood of long-term disability or the need for extended care in a nursing home.
