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.

Six Common Manifestations of Stroke

Firstly, patients may experience language impairment, primarily characterized by unclear speech or sensory aphasia, where they cannot understand others' conversations. Secondly, motor dysfunction is also a very common symptom, typically presenting as hemiplegia on one side of the body. Thirdly, sensory dysfunction can occur, manifested as numbness in one side of the body, an inability to feel pain, and an inability to sense temperature. Fourthly, there may be signs of ataxia, such as unstable walking or standing. Fifthly, there may be difficulties in swallowing, coughing while drinking water, and articulation disorders. Lastly, cognitive dysfunction can also occur, characterized by slow responsiveness and similar symptoms.

Main manifestations of pre-stroke warning signs

The precursor of cerebral thrombosis in neurology is called transient ischemic attack (TIA). As the name suggests, this is a transient disease, mainly characterized by symptomatic speech impairment, facial droop, drooling, episodic dizziness, blurred vision, and episodic numbness and weakness of limbs. These symptoms are generally transient, usually lasting from several minutes to a few hours and can be completely relieved. The precursor of cerebral thrombosis is regarded as an emergency in neurology and must be treated promptly. Delayed treatment can possibly progress to cerebral infarction, severely affecting the patient's quality of life and physical health. In considering this disease, one must immediately rush to the hospital for appropriate treatment with antiplatelet drugs, lipid-regulating drugs to stabilize plaques, and treatments such as volume expansion and fluid supplementation.

Rehabilitation nursing for stroke patients

For the rehabilitation and nursing care of stroke patients, first and foremost, we need to monitor the patient's vital signs, food intake, sleep, as well as bowel and bladder function. Secondly, we should pay attention to their psychological state, checking for signs of tension, anxiety, and depressive emotional reactions. Thirdly, we encourage patients to overcome their illness and to establish confidence in their recovery. Fourthly, we guide patients to actively engage in physical function exercises, as well as daily activities such as eating and dressing to practice their daily living skills. Fifthly, we manage proper limb positioning and patient turning, prevent pressure sores, and also prevent a series of complications such as venous thrombosis and urinary tract infections.

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.

The difference between stroke and cerebral infarction

The difference between stroke and cerebral infarction lies in the scope of stroke, which is broader and includes cerebral infarction. Stroke is divided into hemorrhagic stroke and ischemic stroke. Common types of hemorrhagic stroke include cerebral hemorrhage and subarachnoid hemorrhage. Common types of ischemic stroke include cerebral infarction and cerebral thrombosis. Thus, the scope of stroke is relatively large and includes cerebral infarction. Cerebral infarction occurs when a blockage in the cerebral blood vessels leads to ischemia, edema, and necrosis of the brain tissue in the supplied area, resulting in symptoms of stroke. Additionally, cerebral embolism occurs when an embolus from another part of the body detaches and blocks a brain artery, causing ischemia and necrosis of the brain tissue in the supplied area, also leading to stroke.
