Epinephrine is mandatory for the treatment of cardiac arrest and overwhelming anaphylaxis. However, it must be emphasized that these extreme conditions are the only situations that would require its use in the dental office emergency. There are a few clinicians who maintain the mistaken belief that epinephrine is the drug of choice in shock or shocklike states. There are three principal reasons for disputing this belief.

First, in shock from almost any cause there is decreased venous return to the heart because of peripheral venous pooling. Because the peripheral action of epinephrine is primarily on the arterial side, there is little gain in promoting peripheral vasoconstrictions, which is already present because of the massive release of endogenous catecholamines (epinephrine and norepinephrine). At this point administration of epinephrine may further decrease venous return and tissue perfusion. Second, a possible deleterious effect is an increase in selective ischemia that takes place in certain viscera such as the kidney. Here, as in peripheral vessels, the blood supply is constricted in a compensatory effort to increase blood flow to the more vital brain and heart tissues. Perpetuation of this condition could be undesirable. Third, the possible precipitation of ventricular fibrillation in the ischemic and irritable myocardium is an important factor. This could be especially disastrous in the dental office where defibrillation equipment is usually not available. In early treatment of shock states the patient will benefit more from measures aimed at correction of the primary cause such as hypovolemia rather than misdirected attempts at pharmacologic correction.

Page 3: Emergency Drugs

Desirable properties of this agent include a rapid onset of action; potent action as a bronchial smooth muscle dilator (beta2

properties); antihistaminic actions; vasopressor actions; and its actions on the heart, which include an increased heart rate (21%), increased systolic blood pressure (5%), decreased diastolic blood pressure (14%), increased cardiac output (51%), and increased coronary blood flow. Undesirable actions include its tendency to predispose the heart to dysrhythmias and its relatively short duration of action.

Epinephrine is an important drug during cardiac arrest because no other drug is capable of maintaining coronary artery blood flow while CPR is in progress, which is essential for preserving the chances of survival from cardiac arrest. Epinephrine also preserves blood flow to the brain. In the absence of drug therapy, cerebral blood flow during CPR is minimal; most blood enters the common carotid artery and flows into the external carotid branch, not the internal carotid artery. Following administration of a drug with a-adrenergic properties, such as epinephrine, cerebral blood flow is significantly increased.

Because of its profound bronchodilating effects, epinephrine is also indicated for the treatment of acute asthmatic attacks unrelieved by b2-adrenergic sprays or aerosols.

Side effects, contraindications, and precautions: Tachydysrhythmias, both supraventricular and ventricular, may develop. Epinephrine should be used with caution in pregnant women because it decreases placental blood flow and may induce premature labor. When used, all vital signs must be monitored frequently.

Antihistamines will be of value in the treatment of the delayed allergic response and in the definitive management of the acute allergic reaction (administered after epinephrine has terminated the acute life-threatening phase of the reaction). Antihistamines act as competitive antagonists of histamine. They do not prevent the release of histamine from cells in response to injury, drugs, or antigens, but do prevent access of histamine to its receptor site in the cell and thereby block the response of the effector cell to histamine. Thus, antihistamines are more potent in preventing the actions of histamine than in reversing these actions once they develop.

Nitroglycerin Vasodilators are used in the immediate management of chest pain (such as may occur with angina pectoris or acute myocardial infarction). Two varieties of vasodilator are available: nitroglycerin (TNG) as a tablet and a spray, and an inhalant, amyl nitrite. A patient with a history of angina pectoris will usually carry a supply of nitroglycerin. Tablets remain the most popular form of TNG, although most patients prefer the translingual spray once they have used it. .

Amyl nitrite, another vasodilator, is available for use as an inhalant. It is supplied in a yellow vaporole or a gray cardboard vaporole with yellow printing in a dose of 0.3 mL, which when crushed between one's finger and held under the victim's nose will act in about 10 seconds to produce a profound vasodilation. The duration of action of amyl nitrite is shorter than that of TNG; however, the shelf life of the vaporole is considerably longer. Side effects occur with all vasodilators but they are more significant with amyl nitrite.

Page 4: Emergency Drugs

Side effects, contraindications, and precautions: Side effects of nitroglycerin include a transient pulsating headache, facial flushing, and a degree of hypotension (noted especially if the patient is in an upright position). Because of its mild hypotensive actions, nitroglycerin is contraindicated in patients who are hypotensive, but may be used with some degree of effectiveness in the management of acute hypertensive episodes. Side effects of amyl nitrite are similar to but more intense than those of nitroglycerin. These include facial flushing, pounding pulse, dizziness, intense headache, and hypotension. Amyl nitrite should not be administered to patients who are in an upright position because the patient may feel dizzy and suffer a fall.

Anticonvulsant Seizures that may require acute medical intervention may be associated with epilepsy, hyperventilation episodes, cerebrovascular accidents, hypoglycemic reactions, or vasodepressor syncope. Local anesthetic overdoses or accidental intravascular injection may also require the administration of an anticonvulsant. Current management of a seizure that interferes

Page 5: Emergency Drugs

with ventilation or persists for longer than 5 minutes includes the use of an intravenous benzodiazepine such as diazepam or midazolam.

With its introduction, diazepam became the preferred anticonvulsant. Because seizure disorders are characterized by a stimulation of the central nervous and cardiorespiratory and cardiovascular systems, followed by a period of depression of these same systems, drugs that depress the systems at therapeutic does are more likely to produce postseizure complications. When barbiturates are administered to terminate seizure activity, the degree of postseizure depression is accentuated and its duration prolonged because of the pharmcologic action of the barbiturate.

If the doctor is not adapt at recognizing and managing this situation, the patient may be worse off after the seizure than during it. The benzodiazepines, unlike barbiturates, will usually terminate seizure activity without the pronounced depression of the respiratory and cardiovascular systems.

Analgesic medications will be useful during emergency situations in which acute pain or anxiety is present. In most instances the presence of pain or anxiety will cause an increase in the workload of the heart (and an increased myocardial oxygen requirement) that may prove detrimental to the well-being of the patient. Two such circumstances are acute myocardial infarction and congestive heart failure. The choice of analgesic drugs includes the narcotic agonists morphine sulfate and meperidine (Demerol).

Side effects, contraindications, and precautions: Narcotic agonists are potent CNS and respiratory depressants. Vigilant monitoring of vital signs is mandatory whenever these agents are used. Use of narcotic agonists is contraindicated in victims of head injury and multiple trauma; they should be used with care in persons with compromised respiratory function.

Vasopressor In most emergency situations in which a vasopressor is indicated in the dental office, an agent such as epinephrine will not be the drug of choice. Epinephrine will be used primarily in the management of acute allergic reactions and is rarely employed in cases of clinically mild to moderate hypotension. One reason for this is that epinephrine elicits an extreme antihypotensive response. In addition to an increase in blood pressure, epinephrine causes an increase in the workload of the heart through its effect on heart rate and cardiac contraction; it also increases the irritability of the myocardium by sensitizing it to dysrhythmias.

Vasopressors such as methoxamine (Vasoxyl) and phenylephrine (Neo-Synephrine) are drugs that produce moderate blood pressure elevations through peripheral vasoconstriction.

Methoxamine is a clinically useful vasopressor with sustained action and little effect on the myocardium or central nervous system. Its vasopressor action is associated with a marked increase in peripheral resistance and no increase in cardiac output. A compensatory bradycardia accompanies the rise in blood pressure produced by methoxamine. The onset of the pressor action is almost immediate following IV administration and may persist for up to 60 minutes. After IM injection the response occurs within 15 minutes and persists for 90 minutes.

Page 6: Emergency Drugs

Phenylephrine acts in a similar fashion, with a 5-mg IM dose causing a 30-mm Hg elevation of systolic blood pressure and a 20-mm Hg elevation of diastolic blood pressure, with the response persisting for 50 minutes. As with methoxamine, a pronounced and persistent bradycardia will be noted (average decline in heart rate from 70 to 44 beats per minute).

Antihypoglycemic Glucose preparations are used to treat hypoglycemia that results either from fasting or insulin use in a patient with diabetes mellitus. If the patient is conscious, oral carbohydrates such as chocolate bar, cake icing, or cola drink will act rapidly to restore circulating blood sugar. On the other hand, if the patient is unconscious and acute hypoglycemia is suspected, intravenous administration of 50% dextrose solution is the treatment of choice.

Corticosteroids will be administered in the management of an acute allergic reaction, but only after the acute phase has been brought under control through the use of basic life support, epinephrine, and antihistamines. The primary value of the corticosteroids is in the prevention of recurrent episodes of anaphylaxis. Corticosteroids are also important in the management of acute adrenal insufficiency.

The onset of intravenous corticosteroids, such as hydrocortisone sodium succinate, is delayed, but the drugs can be useful in halting the progression of a major allergic or anaphylactoid reaction. There is also the potential for encountering what appears initially to be a syncopal episode but is in reality the more serious problem of acute adrenal insufficiency in a patient chronically taking systemic corticosteroids to treat a medical condition. For this life-threatening emergency, only the prompt diagnosis and infusion of corticosteroids will be curative.

Hydrocortisone sodium succinate is considered the drug of choice for the dental emergency kit. Corticosteroids are considered second-line drugs primarily because of their slow onset of action.

Antihypertensive The need to administer drugs to decrease excessive elevations in blood pressure is extremely uncommon. First, the incidence of extreme acute blood pressure elevation is quite rare and, second, there are other means of decreasing blood pressure without resorting to parenteral antihypertensive drugs.

Emergency Drugs Oral drugs, such as nifedipine or nitroglycerin, may be administered in most situations to provide a minor depression of blood pressure. The inclusion of a drug in this category is in response to state requirements for general anesthesia permits (and in a few states for parenteral sedation, too).

Anticholinergic Atropine, a parasympathetic blocking agent, is recommended for the management of symptomatic bradycardia (adult heart rate of <60 beats per minute). By enhancing discharge from the sinoatrial (SA) node, atropine may provoke tachycardia (adult heart rate>100 beats per minute). Atropine will be of benefit in situations in which the patient has an overload of parasympathetic activity on the heart. Extremely fearful patients are likely candidates for this response.

Page 7: Emergency Drugs

Atropine is also considered an essential drug in advanced cardiac life support (ACLS), in which it is employed in the management of bradydysrhythmias (hemodynamically significant heart block and asystole).

Side effects, contraindications, and precautions: Large doses of atropine (>2.0 mg) may produce clinical signs of overdosage, including: hot, dry skin; headache; blurred near vision; dryness of the mouth and throat; disorientation; and hallucination. Administration of atropine is contraindicated in patients with glaucoma or prostatic hypertrophy. However, in life-threatening situations the benefits of atropine administration usually outweigh the possible risks.

Respiratory stimulant After oxygen, aromatic ammonia is the most commonly used drug in the emergency situation. It is available in a silver-gray vaporole, which is crushed and placed under the victim's nose until respiratory stimulation is effected. Aromatic ammonia has a noxious odor and acts by irritating the mucous membrane of the upper respiratory tract, thereby stimulating the respiratory and vasomotor centers of the medulla; this in turn increases respiration and blood pressure. Movement of the arms and legs often occurs in response to inhalation of ammonia. This too acts to increase the return of blood from the periphery and aids in raising blood pressure, especially if the patient has been positioned properly.

Side effects, contraindications, and precautions: Ammonia should be employed with caution in persons with chronic obstructive pulmonary disease (COPD) or asthma because its irritating effects on the mucous membranes of the upper respiratory tract may precipitate bronchospasm.

Antihypoglycemic agents will be useful in the management of hypoglycemic reactions occurring in patients with diabetes mellitus or in the nondiabetic patient with hypoglycemia (low blood sugar). The diabetic patient will usually carry a ready source of carbohydrate such as a candy bar or hard candy. Such items should also be available in the dental office for use in the conscious patient with hypoglycemia.

Bronchodilator Asthmatic patients and patients with allergic reactions manifested primarily by respiratory difficulty will require the use of bronchodilator drugs. Although epinephrine remains the drug of choice in the management of bronchospasm, its wide ranging actions on systems other than the respiratory tract has resulted in the introduction of newer, more specific agents known as b2-adrenergic agonists. These agents, of which albuterol is an example, have specific bronchial smooth muscle-relaxing properties (b2) with little or no stimulatory effect on the cardiovascular and gastrointestinal systems (b1) . In the dental situation in which the patient's true cardiovascular status may be unknown, b2 agonists appear more attractive for management of the acute asthmatic episode than agents that have both b1 and b2 agonist properties, such as epinephrine and isoproterenol.

Bronchodilators must be administered precisely as directed. One to two inhalations every 4 to 6 hours is the recommended dosage for albuterol. Nebulized epinephrine (e.g., Primatene-Mist â ) should be administered one to two inhalations per hour. In situations in which these nebulized agents fail to terminate the attack, other bronchodilators (e.g., epinephrine, aminophylline, isoproterenol) must be administered parenterally (intramuscularly or subcutaneously).

Page 8: Emergency Drugs

Side effects, contraindications, and precautions: Albuterol, like other b2 agonists, may have a clinically significant cardiac effect in some patients. This response is less likely to develop with albuterol than with other bronchodilators, thus its selection for the emergency kit. Metaproterenol, epinephrine, and isoproterenol mistometers are more likely to produce cardiovascular side effects, including tachycardia and ventricular dysrhythmias.

16) ISOSORBIDE DINITRATE

Brand name: Isoket IV

Classification: anti – anginal drug

Stock: IV amp 10 mg/ 10 mL

Dose: 10 mg/10mL

Indication: unresponsive left ventricular failure secondary to acute MI, severe or unstable angina pectoris

Page 26: Emergency Drugs

Action: Isosorbide dinitrate is a smooth muscle relaxant. It is particularly effective on vascular and bronchial smooth muscle. Its systemic cardiovascular effects are mainly due to a decrease in venous return (pooling of blood in the peripheral venous system). Consequently, ventricular end-diastolic pressure and volume are diminished, thus reducing cardiac work and implicitly myocardial oxygen requirements. The arterial vessels are dilated as well, though to a lesser degree. This results in a slight drop in aortic and systemic blood pressure relieving the myocardium from a part of its afterload. These nitrate-induced changes account for both the antianginal effects of isosorbide dinitrate and for its beneficial effects in the treatment of congestive heart failure. Side effects/ adverse reactions: severe cerebral flow deficiency and decreased coronary perfusion may develop, nitrate headache and nausea.

Nursing Measures:

Monitor BP and heart rate. Assess location, duration, intensity, and precipitating factors of anginal pain.

Nursing Measures:

Check drug concentration carefully; many concentrations are available. Reduce dosage with hepatic or renal failure. Continuously monitor response when used as antiarrhythmic or injected as local

anesthetic. Keep life-support equipment and vasopressors readily available in case severe adverse

reaction (CNS, CV, or respiratory) occurs when lidocaine is injected. Establish safety precautions if CNS changes occur; have IV diazepam or short-acting

barbiturate (thiopental, thiamylal) readily available in case of seizures. Monitor for malignant hyperthermia (jaw muscle spasm, rigidity); have life-support

equipment and IV dantrolene on standby. Titrate dose to minimum needed for cardiac stability, when using lidocaine as

antiarrhythmic. Reduce dosage when treating arrhythmias in CHF, digitalis toxicity with AV block, and

geriatric patients. Monitor fluid load carefully; more concentrated solutions can be used to treat arrhythmias

in patients on fluid restrictions. Have patients who have received lidocaine as a spinal anesthetic remain lying flat for 6–

12 hr afterward, and ensure that they are adequately hydrated to minimize risk of headache.

Check lidocaine preparation carefully; epinephrine is added to solutions of lidocaine to retard the absorption of the local anesthetic from the injection site.

Be sure that such solutions are used only to produce local anesthesia. These solutions should be injected cautiously in body areas supplied by end arteries and used cautiously in patients with peripheral vascular disease, hypertension, thyrotoxicosis, or diabetes.

Use caution to prevent choking. Patient may have difficulty swallowing following use of oral topical anesthetic. Do not give food or drink for 1 hr after use of oral anesthetic.

Treat methemoglobinemia with 1% methylene blue, 0.1 mg/kg, IV over 10 min. Apply lidocaine ointments or creams to a gauze or bandage before applying to the skin.
