Study Notes
Neurological Injuries and Conditions
- Loss of consciousness, headache, amnesia, nausea, and vomiting are common symptoms of brain injury.
- Contusion involves bruising and bleeding in brain tissue, which can lead to serious complications.
Hematomas
- Subdural Hematoma: Involves venous bleeding under the dura mater.
- Epidural Hematoma: Arterial bleeding between the dura mater and skull; patients typically have a momentary loss of consciousness, regain alertness, and then rapidly deteriorate.
- Monitor for signs of increased intracranial pressure (ICP) after head injuries, including drowsiness and pupillary dilation.
Types of Hemorrhage
- Intracerebral Hemorrhage: Bleeding occurs from lesions within the brain tissue.
- Penetrating Injuries: Sharp objects penetrate the skull and brain.
Increased Intracranial Pressure (ICP) Management
- Symptoms of increased ICP include decreased level of consciousness, agitation, increased systolic blood pressure, and bradycardia.
- Interventions include elevating the head of the bed 30 degrees, avoiding suctioning, administering diuretics or anti-inflammatories, and monitoring for respiratory depression.
Brain Tumors
- Can be malignant, congenital, or hereditary, with environmental factors possibly contributing to development.
- Symptoms depend on the affected brain area and may include visual disturbances, new-onset seizures, and balance challenges.
Seizure Types and Management
- Tonic-Clonic Seizures (Grand Mal): Characterized by muscle stiffening followed by rhythmic movement and loss of consciousness.
- Absence Seizures (Petit Mal): Brief loss of consciousness; patient appears to be staring.
- Myoclonic Seizures: Brief jerking movements of extremities.
- Atonic Seizures (Drop Attacks): Sudden loss of muscle tone.
- Status Epilepticus: Continuous seizures lasting 30 minutes or more, requiring immediate medical intervention.
Pharmacologic Treatment
- Anticonvulsants: Aim to reduce neuron hyperexcitability. Common medications include Phenytoin (Dilantin) and Pregabalin (Lyrica).
- Side effects of Phenytoin include gingival hyperplasia and drowsiness; must be monitored closely.
- Seizure precautions include ensuring patient safety, maintaining low bed positions, and padding side rails.
Head Injury Overview
- Common injuries include lacerations, contusions, abrasions, and hematomas.
- A concussion is defined as trauma without visible skull or brain injury.
Migraine Headaches
- Triggered by factors such as hormonal changes, alcohol, stress, and certain foods.
- Symptoms include unilateral pain, nausea, vomiting, and sensitivity to light and sound.
- Treatments vary from over-the-counter analgesics for mild cases to ergotamines and triptans for severe migraines.
Cluster and Tension Headaches
- Cluster Headaches: Occur in a series, intensely painful, often stress-related, without warning symptoms. Treatment may involve cold applications and Indomethacin.
- Tension Headaches: Caused by prolonged muscle contraction due to stress or other factors, with symptoms of nausea and dizziness. Management includes psychotherapy and non-opioid analgesics.
Seizure Disorder Etiology
- Can result from physical trauma, infections, electrolyte disturbances, and tumors, leading to chaotic electrical impulses in the brain.
- Partial Seizures: Include simple (no loss of consciousness) and complex (impaired consciousness) types, with various motor and sensory symptoms.
Key Nursing Interventions
- Ensure patient safety during seizures by not restraining them, turning them sideways, and keeping the environment free of hazards.
- Document seizures carefully to monitor patterns and provide appropriate interventions.
