Study Notes
Stroke and Neurovascular Conditions
- 1.9 million neurons are destroyed every minute during a stroke.
- Stroke is the leading cause of disability, although many survive the initial event.
- Prompt treatment at a Hyper Acute Stroke Unit (HASU) saves lives and reduces long-term disability.
CVE Assessment
- Patients exhibit TIME CRITICAL signs if:
- Significant ABC issues necessitate nearest emergency department transport.
- A positive FAST (Face, Arms, Speech, Time) test indicates immediate transport to HASU.
- Continuous assess patient en route to appropriate facility.
CVE Management Options
- Airway protection and assist with ventilation if respiratory rate is <10 or >30.
- Oxygen therapy is required only if SPO₂ is <94%.
- Maintain patient comfort in a suitable position and ensure they are Nil By Mouth.
- Provide reassurance to patients and inform relatives of transport details.
Convulsions and Seizures
- Convulsions involve involuntary muscle contractions and alterations in consciousness.
- Epilepsy refers to the recurrent occurrence of unprovoked convulsions, affecting cognitive development in children.
Types of Convulsions
- Generalised Convulsions: Involve large areas of the cerebral cortex.
- Partial Convulsions: Affect localized cortical areas but may progress to generalised.
Generalised Convulsions
- Absence Seizures: Brief episodes of staring or daydreaming with immediate recovery.
-
Bilateral Tonic-Clonic Seizures (BTCS):
- Tonic phase features body rigidity and loss of consciousness.
- Clonic phase involves rhythmic jerking, potential incontinence, and a prolonged post-ictal recovery phase.
Partial Convulsions
- Symptoms vary based on location in the cortex:
- May include consciousness alteration, repetitive actions, and localized clonic activity.
Status Epilepticus
- Defined as continuous convulsions lasting 5 minutes or longer, or a succession of multiple convulsions without recovery.
Causes of Seizures
- Diverse causes unrelated to epilepsy include:
- Hypoxia, kidney failure, hypoglycaemia, systemic infections, alcohol, tumors, stroke, and more.
Convulsion Assessment
- Assessment may include an actively convulsing patient, one in post-ictal phase, or a recovered individual.
- In 80% of cases, seizures resolve within 10 minutes.
Primary Survey for Convulsions
- Response: Assess using AVPU scale for consciousness level.
- Airway: Trismus and potential tongue-biting complicate assessment.
- Breathing: Monitor with ETCO₂ if available; administer oxygen as needed.
- Circulation: Check for capillary refill, skin condition; expect tachycardia.
- Disability: Evaluate AVPU again; consider possible hypoglycaemia.
- Expose: Look for medical alerts and signs of infection.
Convulsions Management
- TIME CRITICAL if:
- Major ABCD problems, serious head injury, status epilepticus, or signs of underlying infections.
- Transport to hospital while maintaining ongoing assessment.
Meningococcal Disease
- Represents bacterial infections of the meninges or bloodstream, impacting around 1200 patients annually.
Meningitis Assessment
- Key signs include reduced response, airway difficulties, breathing compromise, and neurological issues.
- Non-blanching rashes are indicators of meningococcal septicaemia.
Coma
- Defined by an absence of consciousness and loss of responsiveness, typically characterized by a GCS of 8 or below.
- Supportive management is essential; identify and rectify reversible causes where possible.
Causes of Coma
- Factors that can lead to reduced levels of consciousness include:
- Stroke, inadequate airway or respiration, hypoglycaemia, overdose, meningitis, and raised ICP.
Timeliness of Critical Care
- Any ABCD problems indicative of Time Critical situations require immediate and comprehensive assessments, including vital signs and secondary surveys.
