ICH, SAH, Edema, ICP, Seizure, and Safety Priorities
Key Takeaways
- Intracerebral hemorrhage priorities include airway, neurologic trend, smooth BP control, anticoagulant reversal, hematoma expansion surveillance, and neurosurgical readiness.
- Aneurysmal subarachnoid hemorrhage requires rebleeding prevention, aneurysm securement planning, nimodipine administration when ordered, hydrocephalus surveillance, and delayed cerebral ischemia monitoring.
- Large hemispheric, cerebellar, and posterior fossa strokes can deteriorate from edema and intracranial pressure even after an initially stable exam.
- Seizure management starts with safety, airway protection, event timing, ordered rescue medication, and evaluation for nonconvulsive seizures when the exam is unexplained.
- Device and procedure safety includes EVD leveling and drainage precautions, craniectomy protection, fall prevention, aspiration precautions, and careful handoff communication.
Hemorrhage priorities
Intracerebral hemorrhage (ICH) and aneurysmal subarachnoid hemorrhage (SAH) are nursing emergencies because deterioration can occur from hematoma expansion, rebleeding, hydrocephalus, edema, seizure, or medical complications. The first priority remains airway, breathing, circulation, and disability assessment, followed by fast communication with the stroke, neurosurgery, and neurocritical care teams.
For ICH, nursing surveillance focuses on level of consciousness, pupils, motor change, headache, vomiting, blood pressure trend, anticoagulant or antiplatelet exposure, coagulation labs, and repeat imaging readiness. Anticoagulant-associated ICH requires rapid reversal according to drug type and protocol. Warfarin reversal may involve vitamin K plus 4-factor prothrombin complex concentrate; dabigatran and factor Xa inhibitors have specific reversal strategies in many centers. The nurse should not delay escalation while trying to independently select the reversal agent.
SAH-specific concerns
Aneurysmal SAH often begins with sudden severe headache, meningeal symptoms, vomiting, photophobia, decreased consciousness, or collapse. Before the aneurysm is secured, prevent rebleeding by controlling pain, nausea, agitation, and severe blood pressure elevations while avoiding hypotension. Once ordered, enteral nimodipine is a key medication used to improve outcomes related to delayed cerebral ischemia. Monitor for hypotension after doses and communicate if doses are held or not tolerated.
| SAH complication | Usual timing or clue | Nursing focus |
|---|---|---|
| Rebleeding | Early, sudden decline or severe headache | Escalate, BP/pain control, urgent imaging |
| Hydrocephalus | Declining alertness, gait or gaze change, ventricles enlarged | Prepare for EVD or neurosurgical intervention |
| Vasospasm and delayed cerebral ischemia | Often days 3-14 | Trend neuro exam, report new deficits, support euvolemia |
| Hyponatremia | Confusion, weakness, high urine output in some patients | Monitor labs, intake/output, volume status |
| Seizure | Convulsive activity or unexplained decreased responsiveness | Protect airway, treat and evaluate per protocol |
Edema and ICP risk
Large MCA infarcts may swell over 24-72 hours. Cerebellar infarcts and hemorrhages are especially dangerous because posterior fossa edema can compress the brainstem or obstruct cerebrospinal fluid flow. Red flags include worsening headache, repeated emesis, decreasing consciousness, new cranial nerve findings, pupillary changes, abnormal posturing, bradycardia with hypertension, or irregular respirations.
Nursing actions include maintaining ordered head and neck alignment, avoiding hypoxia, treating fever, preventing hypotension, clustering care without hiding neuro changes, and preparing for osmotic therapy, hypertonic therapy, EVD management, decompressive surgery, or transfer to a higher level of care. If the patient has a craniectomy, protect the unshielded brain; avoid pressure on the defect, use ordered helmet protection for mobility, and communicate positioning restrictions in every handoff.
Seizure and device safety
During a seizure, protect from injury, maintain airway positioning, time the event, administer ordered rescue medication, and assess glucose and oxygenation. Afterward, reassess the neurologic baseline. Unexplained decreased responsiveness may require continuous electroencephalography, especially when sedation, aphasia, or severe brain injury makes the exam unreliable.
External ventricular drains require precise leveling, ordered height, sterile handling, drainage documentation, and clamping instructions during transport or repositioning. A sudden change in drainage, damp dressing with clear fluid, waveform change, or neurologic decline is not a routine finding. The SCRN-safe response is to secure the system, assess the patient, and notify the responsible provider promptly.
A patient with warfarin-associated ICH has a declining level of consciousness while reversal orders are being entered. What is the nurse's best priority?
