Study Notes
Hyperventilation and Intracranial Pressure
- Hyperventilation decreases intracranial pressure by causing vasoconstriction, lowering PaCO2. This reduces IICP.
Ketogenic Diet
- A ketogenic diet (high fat, low protein) can help manage seizure disorders.
Seizure Management
- For seizures lasting more than 5 minutes, administer diazepam (Ativan) and call paramedics.
- Chiari malformation type 2 is a common cause of brainstem issues
Cervical Canal
- Structures that are normally inside the brain may protrude into the cervical canal.
Symptoms of Brainstem/Mid Brain Injury
- Signs of brainstem damage include weak cry, stridor, and apnea
Meningitis Vaccines
- Vaccines exist to prevent bacterial meningitis, including Hib, pneumococcal, and meningococcal vaccines
Reye's Syndrome
- Reye's syndrome only develops in response to a viral infection, not bacterial. Aspirin use is linked to developing this syndrome.
Early Signs of Increased Intracranial Pressure
- Headache (projectile vomiting)
- Visual disturbances
- Dizziness
- Decreasing heart rate, respiration
- Changes in pupil responses
- "Sunset eyes" (eyes looking upwards)
- Changes in level of consciousness (LOC)
- Seizures
- Bulging fontanelle/increasing head circumference (infants)
Late Signs of Increased Intracranial Pressure
- Decreased level of consciousness (LOC)
- Decreased motor or sensory responses
- Bradycardia (slow heart rate)
- Irregular breathing patterns (Cheyne-Stokes respirations)
- Abnormal body postures (decorticate/decerebrate)
- Fixed and dilated pupils
Neonatal Seizures
- Phenobarbital is the first-line anti-seizure medication for neonatal seizures.
Seizure Types (Diagram)
- Partial Seizures: Simple (localized awareness), Complex (altered awareness)
- Generalized Seizures: Absence (brief lapses of awareness), Tonic-Clonic (muscle stiffening and jerking), Myoclonic (jerking), Atonic (muscle loss)
Seizure Management - Tonci-Clonic
- During a tonic-clonic seizure, maintain the airway, protect the patient from harm, do not restrain, do not place objects in mouth, and observe and record. Check for:
- Onset
- Body Part Affected
- Level of Consciousness (LOC)
- Muscle Tone
- Pupils
- Cyanosis
- Altered Salivation
- Incontinence
Pediatric Glasgow Coma Scale (GCS)
- A score of 8 or less on the pediatric GCS scale indicates possible need for intubation.
- A normal doll's eye maneuver (eyes look directly ahead during head movement) indicates no mid-brain or pons injury. A deviated eye could signal brain stem or mid brain damage.
- Decorticate posturing (flexed extremities) and decerebrate posturing (extended extremities) are both indications of possible brain stem damage
Anti-epileptic Drugs
- Common anti-epileptic drugs like phenytoin, carbamazepine, and valproic acid
- Adverse effects of each drug must be considered
Important Considerations for Seizure Patients
- Non-compliance with treatment is a frequent cause of seizure treatment failure.
