Medically compromised patient Flashcards
CONSIDERATIONS
(5)
- Thorough up to date medical history
- Appropriate physical exam
- Proper consultations sent
- Be ready to handle various emergencies
- Necessary to work together with patient’s PCP to formulate appropriate decisions
- Thorough up to date medical history
(1)
- At consultation and each follow-up visit
- Appropriate physical exam
(2)
- Full exam performed on consultation examination
- Updated on new visits, and depending on new medical history
WHY MORE RELEVANT TODAY?
* We have the ability to perform
more complicated and lengthy dental procedures
* “The aging of America”
* Polypharmacy
- “The aging of America”
(2)
- Growing geriatric population
- Increased medical risk patients
HYPERTENSION (HTN)
* New BP guidelines from ACC
* — recordings at separate visits
Two
New Guidelines: Normal
Systolic BP
Diastolic BP
Less than 120
Less than 80
New Guidelines: Elevated BP
Systolic BP
Diastolic BP
120-129
Less than 80
New Guidelines: Hypertension (Stage I)
Systolic BP
Diastolic BP
130-139
80-89
New Guidelines: Hypertension (Stage II)
Systolic BP
Diastolic BP
≥ 140
≥ 90
HYPERTENSION
* Treatments available:
(5)
- Lifestyle modifications for 2-3 months
- Diuretics (Watch for K loss)
- One drug therapy
- Multi-drug therapy (Blood Pressure difficult to treat if have to use more than one med)
HYPERTENSION
* Primary (essential)
(2)
- Greatest % of hypertensive pts
- > 95% idiopathic
HYPERTENSION
* Secondary
- 5% with underlying condition: renal/endocrine disorders
HYPERTENSION
* Risk Factors
- Obesity, Smoking, EtOH, hypercholesterolemia, DM, LVH
Hypertensive URGENCY vs Hypertensive EMERGENCY
* Not all patients with elevated BP need to go to the
Emergency Department
BP —- IS ABSOLUTE CUTOFF VALUE for elective procedures
* Emergency procedures would be case by case basis
> 180 mmHg or DBP > 110 mmHg
HTN Urgency
If BP elevated (can get above 200s systolic and130s diastolic) and patient feels normal →postpone dental treatment
AND go see PCP for evaluation and treatment
HTN Emergency
END ORGAN DAMAGE!! → GET PATIENT TO EMERGENCY DEPARTMENT NOW!!!!
* Headache, fatigue, blurry vision, numbness, chest pain, dyspnea, anuria
* Higher risk for stroke and uncontrolled bleeding
ANTI-HYPERTENSIVES
* Beta Blockers
(3)
- Atenolol, propranolol, metoprolol
ANTI-HYPERTENSIVES
* Ca+ channel blockers
(2)
- Verapamil, Amlodipine
ANTI-HYPERTENSIVES
* ACE-Inhibitors
(2)
- Lisinopril, Captopril
ANTI-HYPERTENSIVES
* Diuretics
(2)
- HCTZ, Furosemide
ISCHEMIC HEART DISEASE
* Decreased oxygenated blood to myocardium
* Due to
narrowing or incomplete blockage of coronary artery(ies)
ISCHEMIC HEART DISEASE
NO — DAMAGE
MYOCARDIAL
ISCHEMIC HEART DISEASE
Rx: (4)
stent, angioplasty, CABG, meds
ISCHEMIC HEART DISEASE
If patient has NO restrictions and NORMAL EKG after above procedure, then patient
can be categorized as
ASA II
PROGRESSION OF IHD
(3)
- Stable Angina
- Unstable Angina
- Myocardial Infarction
ANGINA
* Symptom of IHD due to
discrepancy of myocardial oxygen demand and the ability of the
coronary arteries to supply oxygenated blood
Angina
Causes:
(2)
- Narrowing of coronary arteries (LAD a. = “widow-maker”)
- Spasm of coronary arterial wall (Prinzmetals angina)
Angina
Symptoms:
(3)
- Chest pain w/ radiation
- Nausea, sweating, dyspnea, HTN
- Bradycardia, Impending sense of doom
ANGINA
* Question the patient thoroughly concerning:
(4)
- Precipitating events
- Frequency
- Duration
- Severity
Angina
What alleviates pain?
(2)
- Medication, what?
- Rest
ANGINA
STABLE
(5)
- Pain on exertion
- Infrequent episodes
- One nitro tab controls pain
- ASA III
- Medical Consultation prior to treatment
ANGINA
UNSTABLE
(5)
- Pain at rest
- Frequent episodes
- Increasing nitro for pain relief
- ASA IV
- Likely requires inpatient care
- Stable vs Unstable
- Practitioner’s must differentiate
- Guidelines for management:
(5)
- Have nitro available
- Profound LA
- Cardiac dose of epinephrine (0.04 mg in 30 mins)
- Use supplemental oxygen (N2O/O2)
- Anxiety reduction protocol
CARDIAC DOSE OF EPI
*— mg per 30 mins (in OMS clinic we limit — mg in one appointment)
* 1:1,000 →— mg/mL
* 1:10,000 →— mg/mL
* 1:100,000 →— mg/mL

NITROGLYCERIN
* Potent vasodilator:
* Low doses →
* High dose →
reduces myocardial oxygen demand
VENO-dilator
VENO-dilator plus ARTERIO-dilator
NITROGLYCERIN
Dosage:
* — mg metered dose spray (oral/sublingual)
* — mg/tab, bottle of 25, light protected
* Give every 3-5 min, no more than — doses
* Watch the blood pressure!
