The term "DNT" refers to the time from when an acute stroke patient arrives at the hospital to the start of intravenous thrombolytic treatment. Both domestic and international guidelines recommend the DNT to be within 60 minutes—the earlier, the better. This standard was established by the National Health and Family Planning Commission. The time it takes for pre-hospital emergency care and in-hospital medication administration is approximately 60 minutes each. It is only by improving the time from pre-hospital treatment to medication administration within this golden window that we can enhance the patient's survival rate, prognosis, and quality of life, while minimizing disability rates.

What is the goal of rehabilitation during the acute phase of a stroke?

Rehabilitation goals during the acute phase of stroke. In the acute phase, we usually can intervene with rehabilitation treatment 48 hours after the patient’s vital signs have stabilized. The main goals of rehabilitation during the acute phase are to prevent complications such as pressure ulcers, atelectasis pneumonia, urinary tract infections, deep vein thrombosis, and muscle atrophy. Additionally, it aims to improve impaired neurological functions such as sensory, motor, and speech therapies, and to enhance the patient’s ability for self-care and mobility.

Can a stroke be cured?

Stroke can result in sequelae such as deviation of the mouth, slurred speech, hemiplegia, numbness of extremities, coughing when drinking water, hoarseness, and difficulty swallowing. If the stroke affects a smaller area or is not located in a critical area, recovery tends to be better. However, if the infarct is large or occurs in a critical area like the brainstem, sequelae may persist, with partial function recovery possible within about three to six months.

The difference between stroke and cerebral hemorrhage

Stroke includes hemorrhagic stroke and ischemic stroke. Hemorrhagic stroke refers to cerebral hemorrhage, and ischemic stroke refers to cerebral infarction. Thus, they are included in the category of stroke. If symptoms similar to stroke occur, such as facial droop and limb weakness, along with a sudden increase in blood pressure, it is essential to go to the hospital immediately. The first step should be a cranial CT scan to determine whether it is a hemorrhagic or ischemic stroke, to guide further different treatments. Therefore, one must go to the hospital promptly if such symptoms appear.

What does stroke include?

Stroke, translated from the English word "stroke," refers to rapidly occurring pathological changes. Stroke mainly includes two types of diseases: ischemic cerebrovascular disease and hemorrhagic cerebrovascular disease, with ischemic cerebrovascular disease being the most common. Ischemic cerebrovascular disease includes large artery atherosclerotic cerebral infarction, small artery occlusive cerebral infarction, as well as cardiogenic cerebral embolism and other causes of cerebral infarction. Hemorrhagic cerebrovascular disease mainly includes cerebral hemorrhage caused by hypertension, subarachnoid hemorrhage, and cerebral hemorrhage caused by aneurysms or vascular malformations. The onset of a stroke is very aggressive and can severely threaten the patient's health. Once a stroke is suspected, it is critical to rush to the hospital for appropriate diagnostic tests to confirm the diagnosis and provide the most suitable treatment plan.

What are the types of strokes?

The common types of strokes include hemorrhagic stroke and ischemic stroke. Hemorrhagic strokes commonly involve subarachnoid hemorrhage and intracerebral hemorrhage. Subarachnoid hemorrhage often occurs due to the rupture of cerebral aneurysms, causing blood to enter the subarachnoid space. Intracerebral hemorrhage is commonly caused by hypertension leading to the rupture of cerebral blood vessels and subsequent bleeding into the brain parenchyma. Additionally, there is ischemic stroke, commonly presenting as cerebral infarction and cerebral embolism. Cerebral embolism occurs when a blood clot from another part of the body outside the brain, following the blood circulation, blocks a cerebral vessel. Cerebral infarction happens when cerebral arteriosclerosis narrows down to a certain extent, gradually obstructing and forming cerebral infarction. These are the common types of strokes.
