Study Notes
Medical Emergencies in Dental Practice
- Focus: Medical emergencies that can occur during dental procedures
-
Types of Emergencies:
- Respiratory Distress
- Chest Pain (including Acute Myocardial Infarction)
- Syncope
- Seizures
- Allergy-Related Emergencies (e.g., latex allergy, anaphylaxis)
- Hypoglycemia
- Knowledge & Understanding Objectives: Discuss medical emergencies, and management strategies used in a dental setting.
Emergency Preparation
- Basic Life Support (BLS) Certification: Essential for all staff
- Proper Use of Emergency Equipment: Staff should know where emergency equipment is located. This includes instructions on how to use the equipment
- Patient Management: Understand your patient's medical history and any conditions
- Prompt Reaction: Immediate response is crucial in emergencies
- Training: Continuous training to handle emergencies, including team-based approaches, is beneficial and important for practice
- Emergency Plan: A documented office emergency plan is vital, and clear communication protocols, including a dedicated emergency contact list is needed.
Respiratory Distress
- Asthma: Symptoms include narrowing and swelling of airways, accompanied by extra mucus, leading to breathing difficulties
- Manifestations: Shortness of breath, wheezing, chest tightness, anxiety, and cyanosis
-
Management of Asthma Attack:
- Terminate the procedure
- Place the patient in an upright position
- Use a beta-2 agonist inhaler (albuterol) — one puff at a time, every 60 seconds (maximum of 10 puffs)
- Provide oxygen (O2) as needed (if SpO2 < 92%)
- Summon assistance (e.g., call 997)
Chest Pain
- Acute Myocardial Infarction (MI): Caused by coronary artery occlusion, leading to heart muscle death.
- Angina: Chest pain caused by restricted blood flow.
- Manifestations: Sudden, severe chest pain often radiating to the jaw or left arm. Possible sweating, weakness, restlessness, or a sense of impending doom; and shortness of breath
- Silent MI: Classic signs aren't always present
- "Silent MI" Concerns: Women, and diabetics are particularly prone to silent MI
-
Management:
- Call 997 immediately.
- Chew one regular aspirin (325 mg) or 4 baby aspirin (81 mg x 4 times).
- Monitor vital signs (heart rate, blood pressure)
- Manage pain (e.g., morphine, nitrous oxide).
- Provide oxygen (O2) as needed (if SpO2 < 92%).
- Use Basic Life Support (BLS) procedures if needed.
Syncope
- Definition: An abrupt loss of consciousness with rapid recovery, likely caused by reduced blood flow to the brain
- Causes: Cardiac, neurologic, or vasovagal
-
Management:
- Stop the procedure
- Place the patient in the Trendelenburg position
- Apply a cold compress to the forehead
- Administer ammonia inhalant (for complete loss of consciousness)
- Check vital signs
- Call 997
Seizures
- Definition: An excessive hypersynchronous activity of cortical neurons, causing transient neurological symptoms
- Triggers: Excessive physical exertion, alcohol, fever, sleep deprivation, flashing lights, music, hormonal changes, and certain medications
- Causes: Traumatic brain injury, stroke, anoxia, intracranial surgery, acute CNS infections, electrolyte imbalance, drug intoxication
-
Management:
- Remain calm
- Remove potential hazards from the area
- Note the time the seizure begins
- Protect head from injury, by placing a soft surface
- Do not restrain the person
- Do not put anything in the mouth
- Stop bystanders from crowding near the person having a seizure -After the seizure has stopped, place the person in a recovery position -Call 997
Postictal Status
- Definition: Period after the seizure, characterized by altered consciousness, confusion, and various neurological symptoms.
- Duration: Can vary from minutes to hours, depending on the patient's overall health and the type of seizure.
Stroke
- Manifestations: Muscle weakness or paralysis, speech and vision problems, balance issues, confusion, headache, and loss of consciousness. Use the BEFAST mnemonic to assess for stroke.
-
Management:
- Call 997 immediately.
- Reassure the patient.
Allergy-Related Emergencies
- Mild Allergic Reaction: Localized reaction (itching, hives, rash), often managed with oral antihistamines.
-
Severe Allergic Reaction (Anaphylaxis): Life-threatening, requires rapid intervention with epinephrine (often via auto-injector like an EpiPen) — administer (0.3–0.5 mg).
- Assess vitals, and blood glucose
- Follow appropriate protocols for anaphylaxis
- Call 997
- Common Allergen (Dental Clinics): Latex
Hypoglycemia
- Definition: Low blood sugar levels.
- Manifestations: Hunger, nausea, sweating, tachycardia, anxiety, diaphoresis decreased ventilation, and possible loss of consciousness, seizures, and coma.
-
Management (Conscious Patient):
- Assess vitals, and blood glucose.
- Provide oral carbohydrates (orange juice, candy).
-
Management (Unconscious Patient):
- Assess vitals, and blood glucose.
- CPR if necessary.
- If IV access available, administer 25–50 mL of 50% dextrose.
- If no IV access, administer 1 mg of glucagon IM via injection.
- Call 997
Practice Questions (Examples)
- Question 1 (Latex Allergy): A patient develops hives and difficulty breathing during a dental procedure, what is appropriate first action? — Administer epinephrine as an injection, call 997
- Question 2 (Hypoglycemia): A patient experiencing dizziness and blurry vision — administer oral glucose
Summary
- Preparedness: Essential for all dental office staff in handling medical emergencies.
- Emergency Equipment: readily available and easy to use. Knowledge of equipment location essential.
- Communication: Accurate and immediate communication (including calling emergency services) is crucial.
- Procedures: Following protocols (e.g., administering epinephrine, positioning a patient, assessing vitals, administering appropriate treatment) is paramount to safety.
