Recognizing and Managing Seizure Emergencies

At a Glance

For a child with CDKL5 deficiency disorder, time every seizure and follow a written plan for rescue medicine. A shaking seizure lasting 5 minutes, repeated seizures without recovery, breathing trouble, blue lips, or unusual unresponsiveness requires emergency help.

While every day with CDD involves managing seizures, certain situations require immediate action to prevent injury or long-term complications. Understanding the difference between a “typical” seizure for your child and a medical emergency is a critical part of care [1][2].

Seizure First Aid

During a seizure, your immediate actions should focus on safety:

  1. Time the seizure: Check the clock immediately.
  2. Protect from injury: Clear the area of hard objects and place something soft under their head.
  3. Position safely: Roll the child onto their side when safe to do so to keep the airway clear.
  4. Do NOT restrain: Do not try to stop their movements.
  5. Do NOT put anything in their mouth: Never place an object or liquid in a seizing child’s mouth.
  6. Wait to feed: Do not give food or drink until they are fully alert and can swallow safely.

Defining a Seizure Emergency

In the world of epilepsy, there are two primary emergency scenarios you must be prepared for:

  1. Convulsive Status Epilepticus: This is a medical emergency defined as a convulsive (shaking) seizure that lasts for 5 minutes or longer [1][3]. It can also include a series of seizures where the child does not fully wake up or return to their “baseline” state between them [4]. Five minutes is the critical operational threshold because longer seizures become harder to stop and carry a higher risk of brain injury [5][6].
  2. Seizure Clusters: These are “runs” or bursts of seizures that happen more frequently than is usual for your child [7]. Your doctor will provide a specific definition of what a cluster looks like for your child.

The Acute Seizure Action Plan

Every child with CDD must have a personalized, written Acute Seizure Action Plan [8]. This is a “how-to” guide for you, teachers, and other caregivers. A strong plan includes:

  • Descriptions of your child’s different seizure types [9].
  • Clear triggers for when to give rescue medication. (Your neurologist might instruct you to give the medicine at 3 minutes, or after a certain number of seizures in a cluster—always follow your plan, and do not wait for the 5-minute mark if your plan directs earlier action) [10].
  • Specific instructions for the rescue medication, including the drug name, the exact weight-based dose, how to give it (rectal or nasal), and if a second dose is allowed [11][12].
  • Guidelines for when to call 911 or emergency services [8].

Using Rescue Medications

Rescue medications are fast-acting drugs designed to stop a seizure quickly in a community setting [8]. They are typically benzodiazepines, a class of sedatives that calm overactive brain signals [5].

Common rescue options include:

  • Nasal Sprays: Midazolam or diazepam sprays that are absorbed through the lining of the nose [13][12].
  • Rectal Gel: Diazepam gel administered through a specialized applicator [11].

Safety Warning: While these medications are life-saving, they can cause respiratory depression—a dangerous slowing of breathing [14][15]. Ordinary sleepiness (the postictal state) is expected after a seizure or rescue dose. However, you must seek immediate emergency help if you notice:

  • Slow, shallow, irregular, or labored breathing [15].
  • A bluish tint to the lips, skin, or fingernails (cyanosis) [14].
  • An inability to wake the child with loud speaking or gentle shaking.
    (Do not rely solely on a home pulse oximeter reading to decide if a child is safe—always trust your clinical observation of their breathing).

Respiratory and Aspiration Risks

During or after a seizure, children with CDD are at risk for aspiration, which happens when saliva, food, or stomach contents are inhaled into the lungs [16][17]. This can lead to aspiration pneumonia (an infection) or acute respiratory failure [18][19].

Call for emergency help or go to the ER if you see these “Red Flag” signs after a seizure:

  • Difficulty Breathing: Wheezing, gasping, or very fast breathing [16].
  • Signs of Infection: A new fever, persistent coughing, or “gurgling” sounds in the chest. (Aspiration can sometimes be “silent,” so breathing changes or a fever hours later should prompt clinical advice) [20][21].
  • Low Oxygen: If you use a pulse oximeter and see oxygen levels lower than your child’s usual baseline [19][22].
  • Altered Consciousness: If the seizure has stopped but your child remains unusually unresponsive or “out of it” for longer than their normal recovery period, as this could indicate a non-visible seizure is still occurring in the brain [23].

Note: Always keep a copy of your child’s Action Plan and a current list of all their daily medications with you. This information is vital for emergency responders and ER doctors who may not be familiar with CDD [8][24].

Common questions in this guide

When does a seizure become an emergency for a child with CDD?
A shaking or convulsive seizure lasting 5 minutes or longer is a medical emergency. Repeated seizures are also an emergency when the child does not fully wake up or return to their usual baseline between them. Follow the child’s written action plan, which may call for rescue medicine sooner.
What should I do while my child is having a seizure?
Time the seizure, clear nearby hard objects, and protect the child’s head. When it is safe, place the child on their side, but do not restrain them or put anything in their mouth. Wait until the child is fully alert and can swallow safely before offering food or drink.
How do I know when to give my child rescue medicine?
Give rescue medicine exactly as directed in the child’s individualized action plan. The plan may tell you to give it at a specific time, such as 3 minutes, or after a certain number of seizures in a cluster, rather than waiting 5 minutes. Use only the prescribed dose and follow instructions about a second dose.
Is sleepiness after rescue medicine normal, or is it dangerous?
Some sleepiness can occur after a seizure or rescue dose during recovery. Slow, shallow, irregular, or labored breathing; blue lips or skin; or an inability to wake the child with loud speaking or gentle shaking are warning signs that require immediate emergency help.
What signs of aspiration should I watch for after a seizure?
Seek urgent medical help for wheezing, gasping, very fast breathing, persistent coughing, a new fever, gurgling sounds in the chest, or oxygen levels below the child’s usual baseline. Also get help if the child remains unusually unresponsive after the seizure stops. Aspiration can sometimes be silent, so delayed breathing changes or fever still deserve medical advice.
What should be included in a CDD seizure emergency plan?
A written plan should describe the child’s seizure types, the exact rescue medicine and weight-based dose, how to give it, when a second dose is allowed, and when to call emergency services. Keep copies in places such as home, school, and the car, along with a current list of daily medicines.

Questions to Ask Your Doctor

Curated prompts to bring to your next appointment.

  1. 1.What specific duration defines a 'prolonged' seizure for my child, and should we administer rescue medication before the 5-minute mark?
  2. 2.Given my child’s weight and age, what is the exact dose of the rescue medication, and when exactly is a second dose permitted?
  3. 3.How can I tell the difference between the 'postictal' (recovery) state and dangerous respiratory depression after giving rescue medication?
  4. 4.What specific signs of aspiration or respiratory failure should I watch for in the hours following a seizure?
  5. 5.When should we call 911 immediately versus giving rescue medication at home first?
  6. 6.Does my child have a higher risk of aspiration based on their current swallowing or muscle tone, and how does that change our emergency plan?
