After seizure to determine Level of
Consciousness

3-8:
9-12:
13 and up ?
Meaning -

Scores depend on what?

A

Use glascows coma scale if head injury occurs: 3-8 = severe injury of head, 9-12= moderate injury, 13 and up = normal.

Scores depend on Eye opening, verbal responses, and motor responses.

33
Q

Repeated seizures activity within 30 min, or a single seizure lasting more than 5 minutes.

is a medical emergency and is a prolonged seizure lasting longer than 5 minutes or repeated seizures over the course of 30 minutes.

It is a potential complication of all types of seizures.

Seizures lasting longer than how long can cause death!?

A

o Status epilepticus

Repeated seizures activity within 30 min, or a single seizure lasting more than 5 minutes.

10 minutes can = death

34
Q

Common causes of status epilepticus include:

A
  • Sudden withdrawal from antiepileptic drugs
  • Infection
  • Acute alcohol or drug withdrawal
  • Head trauma
  • Cerebral edema
  • Metabolic disturbances
35
Q

Nursing Safety Priority
Critical Rescue

Convulsive status epilepticus must be treated promptly and aggressively!

How?

Priority?

What may occur if untreated?

Drug of choice?

A

Establish an airway and notify the health care provider or Rapid Response Team immediately if this problem occurs!

Establishing an airway is the priority for this patient’s care:

  • Intubation by an anesthesia provider or respiratory therapist may be necessary.
  • Administer oxygen as indicated by the patient’s condition.
  • establish IV access with a large-bore catheter and start 0.9% sodium chloride.
  • The patient is usually placed in the intensive care unit for continuous monitoring and management.
  • Blood is drawn to determine arterial blood gas levels and to identify metabolic, toxic, and other causes of the uncontrolled seizure.
  • Brain damage and death may occur in the patient with tonic-clonic status epilepticus.
  • If Left untreated, metabolic changes result, leading to hypoxia, hypotension, hypoglycemia, cardiac dysrhythmias, or lactic (metabolic) acidosis.
  • Further harm to the patient occurs when muscle breaks down and myoglobin accumulates in the kidneys, which can lead to renal failure and electrolyte imbalance. This is especially likely in the older adult.
  • The drugs of choice for treating status epilepticus are IV-push lorazepam (Ativan, Apo-Lorazepam) or diazepam (Valium). Diazepam rectal gel (Diastat) may be used instead.
  • Lorazepam is usually given as 4 mg over a 2-minute period. This procedure may be repeated, if necessary, until a total of 8 mg is reached.

Emergency Care:
Acute Seizure and Status Epilepticus Management. Seizures occurring in greater intensity, number, or length than the patient’s usual seizures are considered acute.

They may also appear in clusters that are different from the patient’s typical seizure pattern.
Treatment with lorazepam (Ativan, Apo-Lorazepam) or diazepam (Valium, Meval, Vivol, Diastat [rectal diazepam gel]) may be given to stop the clusters to prevent the development of status epilepticus. IV phenytoin (Dilantin) or fosphenytoin (Cerebyx) may be added

36
Q

Nursing Safety Priority Drug Alert

  • To prevent additional tonic-clonic seizures or cardiac arrest, a loading dose of what is given?
A

IV phenytoin (Dilantin) is given, and oral doses are administered as a follow-up after the emergency is resolved.

  • Initially give phenytoin at no more than 50 mg/min using an infusion pump.
  • If the drug is piggybacked into an existing IV line, use only normal saline as the primary IV fluid to prevent drug precipitation.
  • Be sure to flush the line with normal saline before and after phenytoin administration
37
Q

syndrome in which there is a sudden onset of excessively high blood pressure. It is more common in people with spinal cord injuries that involve the thoracic nerves of the spine or above (T6 or above).
