    Study Notes

    Medically Compromised Patients in Dentistry

    • Cardiovascular diseases are a significant concern. Ischemic heart disease, infected endocarditis, and hypertension & hypotension are examples of conditions that may affect dental treatment.
    • Recognizing existing medical conditions is crucial.
    • Adequate preparation is vital. This includes premedication, prophylaxis, adjustments to the procedure to account for potential adverse effects.
    • Postoperative considerations are essential. Managing bleeding and infections are important.
    • Understanding urgency vs. emergency is important. Urgent situations require prompt response but aren't immediately life-threatening, while emergencies require immediate action to address an immediately life-threatening problem. Syncope, hypoglycemia, seizures, asthma attacks, angina, and mild allergic reactions are examples of urgent problems. Cardiac arrest, anaphylaxis, and obstructed airways are examples of emergencies.

    Preparation for Emergencies

    • Gather a comprehensive medical history from every patient and update it at each visit.
    • When scheduling appointments, remind patients to take their normal medications on the day of their appointment.
    • All staff members should be trained in basic first aid procedures and CPR.
    • The office should have a written emergency plan. Emergency telephone numbers should be posted at each phone.

    Basic Life Support (BLS)

    • In all emergency situations, initial management always involves applying basic life support.
    • Drug therapy follows the application of ABCs of CPR.
    • The ABCs of CPR are assessment and treatment of airway, breathing, and circulation in that order (per AHA 2010 guidelines).

    Steps of Basic Life Support by CPR

    • Cardiopulmonary Resuscitation (CPR): Lay the patient flat, raise the foot end to aid venous blood return to the heart, turn the head to one side to prevent tongue from blocking the airway, and start suctioning to clear any secretions.
    • Artificial Ventilation: If the patient is not breathing, provide artificial ventilation using a tight-fitting face mask and an ambu-bag connected to an oxygen cylinder.
    • External Cardiac Massage: If no pulse is felt (carotid pulse most reliable), begin external cardiac massage by pressing on the lower sternum with one hand over the other, at a rate of 60-70 times per minute. Continue until the heart starts beating and a good pulse returns.
    • Summon Medical Help: Summon medical help immediately, and shift the patient to a hospital for expert care.
    • Assessment of Consciousness: Assess the patient's level of consciousness.
    • Call for Help: Call for help after assessing consciousness.
    • Position Patient: Place the patient in a suitable position, depending on the context.
    • Opening Airway: Assess and open the airway. This may involve head tilt-chin lift, jaw thrust, or a combination of both.

    Assessing Airway Patency and Breathing

    • Assess airway patency and breathing.

    Artificial Ventilation

    • Artificial ventilation is provided if needed following the airway assessment.

    Assessing Circulation

    • Assess circulation to determine whether adequate circulation is established. This is done after assessing the airway and breathing.

    External Chest Compression

    • Perform external chest compression with either one or two rescuers, as appropriate for the situation.

    Health Assessment

    • Taking a thorough medical history and vital signs help identify patients at risk.
    • Extensive procedures for high-risk patients might be better performed in a hospital environment to evaluate and manage risk more effectively.

    ABC of any Emergency

    • Maintain the supine position.
    • Administer 100% oxygen.
    • Evaluate airway, breathing, circulation.
    • Check vital signs (temperature, blood pressure, pulse, respiratory rate).

    Estimation

    • One or two life-threatening emergencies are estimated to occur during a general dentist's lifetime practice.

    Types of Emergencies in the Dental Clinic

    • Syncope (fainting) is the most frequent emergency in dental clinics, and it is estimated at 50% of incidents.
    • Other common events are mild allergic reactions, angina, hypotension, seizures, and asthma attacks.

    Patient Classification

    • Patients are classified according to their physical condition using the American Society of Anesthesiologists (ASA) classification. ASA Type I are normal patients, and Type V are considered morbid or very high risk.

    Treatment Options

    • Treatment options are based on the ASA classification, and patients are treated either in the office, hospitalized, or hospitalized only for emergency care.
    • Anxiety and stress related to dental visits can be managed. This can be done through premedication, short appointments early morning, avoiding excessive amounts of epinephrine, using nitrous oxide-oxygen.

    Stress Reduction Protocol

    • Protocol before a visit involves night before medication, sleeping pills, and day of procedures involves short-acting barbiturates (optional).
    • Instructions during a dental appointment include relaxing background music, reassurances to the patient, no sudden surprises or noise, instruments out of view, profound local anesthesia, IV sedation (optional), or nitrous oxide sedation (optional).
    • Instructions after the visit include further reassurances, details of expected postoperative recovery, effective analgesics, and post-procedure follow-up phone calls for the patient.

    Who are Medically Compromised Patients?

    • Medically compromised patients are those who have significant medical conditions that necessitate changes to standard dental treatment protocols.

    Why the Dentist Assesses Patient Condition?

    • The dentist assesses the patient's condition to identify any source of infection or condition that could compromise successful treatment, and to restore optimal oral health and function.

    How Dentists Assess a Patient's Condition?

    • Thorough medical and dental history, including medications, documented on the dental chart.
    • Full mouth intraoral radiographs and panoramic radiographs.
    • Panoramic radiographs are used for patients who can't tolerate intraoral films or those who are edentulous.

    Initiate Preventive Therapy

    • Start preventive therapy.

    Arrange Treatment

    • Arrange treatment based on the patient's condition.

    Arrange Follow-up

    • Arrange follow-up care.

    Physical Evaluation and Risk Assessment

    • To successfully treat medically compromised patients, the dentist carefully evaluates and assesses the risk to ensure the patient can securely tolerate the planned procedure.

    Physical Evaluation and Risk Assessment- Part Two

    • Risk assessment involves at least four components including nature/severity/stability of the patient’s medical condition, functional capacity, emotional state of the patient, and type/magnitude of procedure (invasive or noninvasive).
    • All factors need to be carefully weighed.
    • Each patient situation requires thoughtful consideration to ascertain whether the advantages of dental treatment outweigh potential risks to the patient.

    Physical Evaluation and Risk Assessment Considerations

    • If a patient has symptomatic heart failure, the risk of taking radiographs (a noninvasive procedure) is minimal if the patient is not anxious or fearful.
    • Conversely, the risk of a full mouth extraction (an invasive procedure) might be significant if the patient is very anxious.

    Physical Evaluation and Risk Assessment- Parts Three and Four

    • Cornerstone of evaluation and risk assessment is a thorough medical history, physical examination, laboratory tests, and medical consultation.
    • Detailed medical history interviews include conversations to collect the patient's verbal responses and printed questionnaires for patients to fill out. Post-procedure follow-up questioning provides further information about patient responses to treatment.
    • Common systemic issues that dentists should be alerted to include cardiovascular problems (like high blood pressure), endocrine problems (like diabetes), hematological problems (like hemophilia), gastrointestinal and liver diseases, respiratory diseases like asthma, genitourinary tract diseases, and neurological disorders like epilepsy.

    Cardiovascular Diseases

    • Any dental procedure that causes injury to soft tissues or bones may result in transient bacteremia and infective endocarditis (IE) in susceptible patients. This is true even in minor dental procedures.
    • Main signs and symptoms include chest pain, dyspnea, cyanosis, palpitation, syncope, edema of ankles and fingers, cold pale extremities, and easy fatigue.

    Ischemic Heart Disease

    • Ischemic heart disease is typically caused by reduced coronary blood flow and/or increased myocardial oxygen demand.
    • Main disorders associated with ischemic heart disease are: angina pectoris, myocardial infarction, and congestive heart failure.

    Angina Pectoris

    • Angina pectoris is myocardial ischemia resulting from an imbalance between coronary blood flow and oxygen demand, leading to a temporary inability of coronary arteries to supply heart muscle with oxygenated blood.
    • Signs and symptoms include substernal pain that radiates to the left shoulder, dull, heavy, or pressure sensation lasting < 5 minutes, prompt relief with rest or nitroglycerin sublingual tablets, and potential dental problems such as stress, angina attack, MI, and sudden cardiac arrest—both stable and unstable.

    Dental Management Considerations for Ischemic Heart Disease

    • Identifying patients and medical consultation with focus on short appointments in the morning.
    • Semi supine chair position, have sublingual tablets (nitroglycerine) on hand.
    • Premedication with diazepam (for stress) and one nitroglycerine tablet.
    • Use local anesthesia with 1:100,000 adrenaline to numb the area to be treated. This material is injected slowly, with a maximum of 2 carp.
    • Continue monitoring vital signs for 15 minutes following appointments depending on the patient's condition, to address emergencies as needed.

    Myocardial Infarction (MI)

    • Myocardial infarction (MI) is caused by coronary artery occlusion by thrombus, causing deficient coronary blood supply to a region of myocardium.
    • This can cause cellular death and necrosis.
    • The anginal attack may last for minutes.
    • Symptoms include prolonged anginal pain, tachycardia and irregular pulse, nausea and vomiting, difficulty breathing, and pain not relieved by nitroglycerine or rest.

    Potential Dental Problems from Cardiovascular Conditions

    • May present with cardiac arrest, MI, angina pectoris, congestive heart failure, infective endocarditis, and electrical interference with a pacemaker.

    Dental Management Recommendations for Patients with MI or Unstable Angina

    • Do not perform elective dental procedures in a patient who has recently had a myocardial infarction or is experiencing unstable angina.
    • In emergency cases, consult with a physician before proceeding with dental treatment. The focus in emergency cases should be on pain control, such as giving antibiotics for infections, doing pulpotomies rather than extractions, and giving 5 mg of valium.

    Congestive Heart Failure

    • CHF is an inability of the heart to pump enough blood to fulfill the metabolic needs of the body.
    • Symptoms include fatigue, dyspnea, ankle edema, and orthopnea.
    • High-risk dental problems associated with CHF include myocardial infarction, bleeding, cerebrovascular accident (CVA), and endocarditis.

    Dental Management Recommendations for Patients with Congestive Heart Failure

    • Identifying patients and medical consultation. Ensure the patient is in an upright position to avoid fluid buildup in the lungs.
    • Check prothrombin and bleeding times, and administer preoperative antibiotics as needed.
    • Terminate the appointment if the patient shows fatigue and monitor signs closely for 15 minutes if necessary following the visit.
    • Avoid gag stimulation and atropine. Avoid vasopressors, excessive use of gingival cord, and manage any complications.

    Infective Endocarditis (IE)

    • IE is inflammation of the heart's inner tissue (specifically the heart valves) due to microbial pathogens (bacteria or fungi).
    • Often patients with a certain heart condition may come to the dental clinic. For them, antibiotic prophylaxis is often given to prevent IE.

    Individuals at Risk for IE

    • Patients with rheumatic heart disease, mitral valve prolapse, prosthetic valves, or a history of IE are at a higher risk.

    Procedures That May Cause IE

    • Tooth extractions, periodontal surgery, and rubber dam placement are procedures that have an increased risk of IE.
    • Even routine procedures like brushing, flossing, and chewing food can cause IE in susceptible individuals.

    Antibiotic Prophylaxis Necessity

    • Recent evidence suggests no consistent need for prophylactic antibiotics for most dental procedures.

    Antibiotic Prophylaxis Recommendations

    • Antibiotic prophylaxis is only indicated for patients with prosthetic heart valves, a history of infective endocarditis, certain congenital heart diseases, or cardiac transplant recipients with valvular pathology.

    Antibiotic Dosage

    • Standard dosages include amoxicillin (2 grams, one hour before treatment), ampicillin (2 grams, one hour before treatment), clindamycin (600 mg, one hour before treatment).

    Special Cases

    • Patients with prosthetic valves typically take anticoagulants. These patients require adjusted antibiotic dosages based on INR (international normalized ratio) due to the risk of bleeding.
    • Patients already on penicillin antibiotic treatment should postpone dental treatment until their condition is concluded. If necessary, clindamycin can be used instead.

    Hypertension

    • Hypertension is defined as a blood pressure exceeding 140 mmHg systolic and 90 mmHg diastolic (or greater).
    • Hypertension is a common cause of cardiovascular and kidney disease.

    Hypertension Classification

    • Classification of hypertension includes categories like normal, prehypertension, grade 1 hypertension, and grade 2 hypertension based on systolic and diastolic measurements.

    Be Alert For: Hypertension Situations

    • Monitor for elevated blood pressure.
    • Patients might experience symptoms like headache, jitters, or pressure behind the eyes.

    Dental Management Considerations for Mild-to-Moderate Hypertension

    • Consult with the patient's medical doctor.
    • Monitor blood pressure during the procedure, especially when epinephrine is used.
    • Administer anesthesia slowly to avoid intravascular injection.
    • Use an anxiety reduction protocol.
    • Avoid sudden changes in posture to prevent hypotension and syncope.
    • Avoid intravenous solutions containing sodium.

    Dental Management Considerations for Severe Hypertension

    • Delay elective dental procedures until blood pressure is controlled.
    • Refer to a specialist for emergent problems.
    • Avoid antibiotics like erythromycin and clarithromycin with CCBs, as these combinations can lead to hypotension.
    • Avoid using NSAIDs in the long-term for pain control, as they may interfere with antihypertensive medications.
    • Avoid using epinephrine-containing gingival retraction cords due to high epinephrine concentrations causing tachycardia and high blood pressure.
