Study Notes
Altered Mental Status
- Causes include toxic-metabolic factors such as anoxia, hypoglycemia, and carbon monoxide poisoning.
- Altered mental status can result from structural causes, including brain tissue destruction or space-occupying lesions.
- Patients with altered mental status should maintain an SpO2 of 94% or higher.
Stroke Identification
- Transient Ischemic Attack (TIA) is indicated by temporary symptoms such as facial numbness and weakness that resolve quickly.
- LAPSS has a 97% success rate in accurately identifying strokes.
- The Cincinnati Prehospital Stroke Scale (CPSS) relies on speech as a screening criterion.
- High priority is assigned to patients presenting with stroke symptoms for transport.
Headache Assessment
- A severe headache described as the "worst headache ever" necessitates rapid transport.
- Clinical manifestation of migraines may include symptoms like photosensitivity.
- A blood pressure reading of 160/120 could indicate vascular headaches.
Stroke Types and Treatment
- Embolic strokes occur when a clot breaks free and lodges in the brain.
- Hemorrhagic strokes involve ruptured blood vessels in the brain and are not treatable with clot-busting drugs.
- Symptoms of a stroke that subside within 24 hours may indicate a TIA, but persistence beyond 25 minutes suggests a small stroke.
Patient Monitoring
- Regular assessments of unconscious patients should occur every 5 minutes to monitor changes in mental status, breathing, and circulation.
- Attention should be focused on the respiratory system as the patient’s condition deteriorates.
Emergency Protocols
- Serious headache causes include hypertension, subarachnoid hemorrhage, and cyanide poisoning; heart attacks are not typically associated.
- The jaw-thrust maneuver should be applied to patients exhibiting sonorous respirations after an altered mental status.
Importance of Hospital Evaluation
- Even if stroke symptoms have resolved, hospital evaluation is necessary to determine the cause of TIA.
- The American Heart Association emphasizes the importance of rapid recognition of stroke symptoms and dispatch as critical components of the "Stroke Chain of Survival."
