Study Notes

Medical Emergency Management

Medical Emergencies: A range of situations requiring immediate medical attention. These can vary significantly in severity and cause.

American Society of Anesthesiologists (ASA) Physical Status Classification System

ASA PS 1: Normal, healthy patient with little to no dental anxiety. No modifications needed for treatment.
ASA PS 2: Patient with mild systemic disease or extreme dental anxiety. Medical consultation may be required, and sedative or pain control techniques might be utilized during procedures.
ASA PS 3: Patient experiencing severe systemic disease. Exercise caution during treatment; the patient needs to rest. Sedative/pain control techniques are critical.
ASA PS 4: Patient with severe systemic disease that poses a constant threat to life. Important to postpone elective dental care; treat emergencies in a hospital setting.
ASA PS 5: Moribund patient not expected to survive without surgery. Only palliative pain management should be offered.
ASA PS 6: Declared brain-dead patient whose organs are harvested for transplantation. No treatment is indicated.

Preventing Emergencies

Five-Point Plan: A strategy to proactively avoid emergencies
- Employ systematic patient assessment procedures.
- Document and maintain comprehensive patient records.
- Implement stress-reduction protocols.
- Recognize and address early signs of distress.
- Establish a clearly defined team management plan for preparedness.

BLS Certification

Essential: Licensed dental hygienists must obtain BLS certification.
Source: Training provided by American Heart Association (AHA). BLS for Healthcare Providers Manual provides the most current information.

In Every Emergency

Dental Treatment Termination: Terminate treatment when an emergency arises.
Removing Items: Remove all dental items from the patient's mouth.
Patient Awareness: Inform the patient that further dental treatment is suspended.
Unresponsive Patients: Assess pulse and breathing. Initiate Cardiopulmonary Resuscitation (CPR) if needed.
Blood Pressure Monitoring: Monitor blood pressure, pulse, and respirations.
Positioning: Position the patient to optimize circulation (e.g., upright for high blood pressure, semi-supine for low blood pressure).
EMS Activation: Call Emergency Medical Services (EMS) if situation warrants.
Identifying Symptoms: Evaluate patient symptoms, including medications, food intake, and pre-existing conditions.

Division of Duties

Clear Role Definitions: Team members are assigned specific duties to keep the emergency response organized. Each person's role needs to be clearly defined.

Emergency Team

Team Member 1 Role: Evaluates the patient's condition and stays with them while requesting help.
Team Member 2 Role: Gets emergency supplies, drugs, oxygen, and records data.
Team Member 3 Role: Determines if 911 is needed and directs the call.

Calling for Help

911: The standard emergency number for West Liberty and most clinics.

Equipment Essentials

Emergency Cart: A cart stocked with essential medical components, including drugs and tools.

Drug Kit Contents

Doctor Role: The doctor assembles the kit with appropriate drugs.
Basic Kit Contents: Includes epinephrine, Benadryl, aspirin, nitroglycerin, bronchodilators, glucose, oxygen, and sometimes naloxone.

Use: Injectable bronchodilator (EPI Pen) used for severe allergic reactions (anaphylaxis).
Dosage: Adult: 0.3 mg IM/Subcutaneous; Child: 0.15 mg IM/Subcutaneous.

Diphenhydramine (Benadryl)

Action: Histamine blocker/antihistamine used for allergic reactions (especially mild to moderate).
Form: Injected or in tablet form.

Allergy Signs

Mild: Skin rash, redness, itching, hives (urticaria).
Severe: Severe airway constriction, difficulty breathing, possible loss of consciousness, and a significant drop in blood pressure.

Types of Reactions

Type I: Immediate, often mild or severe, involving skin reactions and rapid swelling of the skin.
Type IV: Delayed allergic reactions, such as allergic contact dermatitis.

Nitroglycerin

Use: Vasodilator for angina treatment.
Important considerations: Patient must have their own prescription (RX). Before administering, check the patient's blood pressure (BP), ensuring it's at or above baseline.
Administering via Spray: Metered spray is frequently used, providing consistent and quick relief.
Administering via Tablets: .4 mg tablet, may be used sublingually for angina treatment.

Bronchodilator (Ventolin and Proventil)

Action: Treats bronchospasm, commonly caused by allergies or exercise in an acute asthma attack.
Administering: Patients typically use their own inhalers (RX is needed). Relief typically occurs within 30-60 seconds.

Glucose (Sugar)

Purpose: Used for hypoglycemia (low blood sugar), a common emergency in dental offices.
Forms: InstaGlucose tubes, orange juice, cake icing, and soft drinks are readily available options.

Aspirin

Usage: Primarily for suspected heart attacks. Always call 911 first.
Dosage: Low dose (81 mg) is commonly used; regular dose (325 mg) might be necessary.

Oxygen

Availability: Cylinder, 3 ft high, green in color.
Contraindications: Avoid in patients with COPD or emphysema to prevent hyperventilation.

Oxygen Delivery Systems

Types: Include cannula, face mask, non-rebreather mask, bag-valve mask, demand valve.
Usage: Based on patient need and condition.

Portable Oxygen Delivery System

Utility: A portable unit of oxygen delivery.

Masks

Purpose: Intended to provide oxygen and facilitate CPR.
Examples: Disposable masks, bag-valve masks, or Ambu bags.

AED (Automated External Defibrillator)

Function: A small, portable device intended to assess heart rhythm and deliver electric shocks to correct potentially life-threatening arrhythmias.

Additional Supplies

Glucometer: Utilized to assess blood glucose levels before and after meals (normal levels are crucial).
Magill Forceps: Used for removing foreign objects from the trachea, ensuring the airway is clear.
Pulse Oximeter: Measurable oxygen saturation levels in the blood are necessary to assess breathing issues.

Prevention of Medical Emergencies

Medical History Assessment: Carefully review patient history, focusing on medications, allergies, and prior medical issues.
Medication Tracking: Document medications currently active.
Vital Signs Check: Document vital signs before or during treatment.
Review of potential Reactions/Allergies: Allergies, drug reactions, stress management, and post-treatment care are all essential elements in the prevention strategy.

Syncope

Definition: Temporary loss of consciousness caused by insufficient blood flow to the brain.
Prevalence: A frequent emergency in dental clinics.
Treatment: Supine positioning and addressing potential causes (e.g., postural hypotension).

Symptoms (General)

Symptom Clusters: Various symptoms might occur, including pallor, dilated pupils, sweaty/clammy skin, lightheadedness, and nausea up to a drop in blood pressure.

Causes of Syncope

Anxiety/Fear: Anxiety, especially in young women, can be a frequent trigger.
Postural Hypotension: A sudden drop in blood pressure when changing position.
Blood Loss: Insufficient blood volume to support normal circulation.
