tPA is an effective emergency treatment for eligible patients with acute ischemic stroke and should be administered within the therapeutic time window, generally 3 to 4.5 hours from the first onset of symptoms. Nursing care is central to ensuring the safety and effectiveness of this treatment and includes the following:
1. Rapid Assessment and Early Recognition of Stroke Symptoms
· Use the F.A.S.T. protocol (Face, Arms, Speech, Time).
· Obtain an accurate medical history, particularly the exact time when symptoms began or the last known well time.
· Notify the medical team immediately to expedite transfer and brain imaging with CT or MRI.
2. Preparation for tPA Administration
· Confirm that the patient meets the eligibility criteria for tPA:
o Age: 18 years or older.
o Clinical diagnosis: confirmed acute ischemic stroke.
o Symptom onset: within the 3- to 4.5-hour treatment window.
o Brain imaging: CT or MRI shows no intracranial hemorrhage.
o Neurological deficit: clinically evident and functionally significant; the NIH Stroke Scale is used to determine severity.
o Weight: used to calculate the tPA dose (0.9 mg/kg; maximum dose 90 mg).
· Confirm that the patient has no contraindications to tPA, including:
o Current or previous intracranial hemorrhage.
o History of cerebral hemorrhage or an untreated cerebral aneurysm.
o Brain surgery, head injury, or stroke within the previous three months.
o Uncontrolled blood pressure of 185/110 mmHg or higher at presentation.
o Bleeding disorder or platelet count below 100,000/µL.
o Use of anticoagulants, such as heparin within the previous 48 hours, with an elevated INR or aPTT.
o Blood glucose below 50 mg/dL or above 400 mg/dL.
o Intracranial tumors or serious vascular disease.
· Obtain informed consent from the patient or family whenever possible.
· Collect blood samples for the required investigations, including coagulation studies, liver-function tests, and complete blood count (CBC).
· Insert an appropriate intravenous cannula and monitor vital signs.
3. Monitoring During tPA Administration
· Administer the dose according to the hospital protocol: 10% of the total dose as an IV bolus and the remainder by infusion over 60 minutes.
· Monitor vital signs every 15 minutes during the first hour, every 30 minutes during the next two hours, and then hourly for 24 hours.
· Monitor neurological status closely to detect any sudden deterioration.
4. Rapid Recognition of Potential Complications
o Monitor for signs of internal or intracranial bleeding, including decreased level of consciousness, sudden headache, vomiting, or new neurological changes.
o Inspect needle and catheter sites for external bleeding.
o Monitor for allergic manifestations or a severe medication reaction; these are uncommon but possible.
5. Care After tPA Administration
· Do not administer anticoagulant or antiplatelet medication during the first 24 hours after tPA unless explicitly prescribed by the physician.
· Avoid invasive procedures or punctures, such as lumbar puncture or catheter insertion, during the first 24 hours whenever possible.
· Repeat brain imaging after 24 hours to exclude hemorrhage before starting additional antithrombotic medication.
· Continue close monitoring of neurological status and vital functions.
6. Patient Education and Psychological Support
· Explain the treatment to the patient and family, including the importance of timely tPA administration.
· Provide psychological support during the acute phase.
· Follow the rehabilitation plan after treatment according to the patient’s condition.
