DESCRIPTION. Adult Dosage for Lidocaine: Dosage for cardiac arrest from ventricular fibrillation or pulseless ventricular tachycardia: Initial . You don't have an irregular heart rhythm with ventricular fibrillation, you don't have a heart rhythm. Pro Tip: VFib is a non-perfusing and lethal dysrhythmia that is most commonly seen during the first few minutes of cardiac arrest. Epinephrine is the drug of choice for the treatment of ventricular asystole and should be administered in sufficient dosage under electrocardiographic control. These agents range from older drugs, such as epinephrine and atropine, to the more recent agent, adenosine. It should . Note A. Initial dose can be followed by ONE 150 mg IV/IO push in 3 to 5 minutes If rhythm converts with return of pulses, refer to ROSC policy. There are no absolute contraindications against using epinephrine. There is a high incidence of cardiovascular side effects with epinephrine use. It is the initial drug of choice for treating bronchoconstriction and hypotension resulting from anaphylaxis as well as all forms of cardiac arrest. In a child with ventricular tachycardia and ventricular fibrillation with a nonparticular or uncertain past history, electrical cardioversion, epinephrine, and . Adrenaline/epinephrine is contraindicated in patients with shock (other than anaphylactic shock) . If VF/VT continues: Epinephrine 1:10,000 1.0 mg IV/IO; repeat q 3-5 minutes; If VF/VT persists after three defibrillations or recurs: Consider Amiodarone 300 mg IV/IO push (diluted in, or followed by, 20 to 30 ml NS). 5 In VF, the etiology of arrest is often attributed to either acute ischemia or non-ischemic arrhythmia.

Patients w/ ventricular fibrillation; hyperthyroidism, HTN & cardiac arrhythmias. In other words, lidocaine decreases automaticity and suppresses ventricular arrhythmias. Epinephrine is also used in the treatment of the severe type of hypotension or it is the ACLs drug for hypotension treatment. Initial dose can be followed by ONE 150 mg IV/IO push in 3 to 5 minutes Lidocaine would be contraindicated if there is a known hypersensitivity to lidocaine or derivatives like xylocaine, novocaine, etc. preferably following the first dose of epinephrine and prior to intubation to reverse the immediate effects of acidosis b.

Procaine amide and quinidine have been found to be ineffective and even harmful . To determine if naloxone has salutary effects during cardiac arrest with conventional closed-chest cardiopulmonary resuscitation (CPR), ten dogs were studied during 20 minutes of ventricular fibrillation (VF) and CPR and during a 30-minute postcountershock period. ventricular fibrillation if used in the treatment of anesthetic cardiac accidents. epinephrine may precipitate or aggravate angina pectoris as well as produce ventricular arrhythmias [see Drug Interactions (7) and Adverse Reactions (6)]. Another unique contraindication to be aware of is catecholaminergic polymorphic ventricular tachycardia. Epinephrine stimulates alpha-, beta1-, and beta2-adrenergic receptors in dose-related fashion. . If disturbances in cardiac rhythm occur, withhold epinephrine and notify physician immediately. If ventricular fibrillation or pulseless ventricular tachycardia persists after 2 minutes of CPR, you will administer another shock. Patients who have been resuscitated from ventricular fibrillation arrests should be evaluated for risk of recurrence. Epinephrine should be used cautiously in the elderly and in patients with . [2][3]In the operating room (OR) setting, epinephrine is also used as a local anesthetic block. CONTRAINDICATIONS. Google Scholar 3. The patient is One dose of epinephrine was given after the second shock. Dopamine is also contraindicated in clients with tachyarrhythmias, ventricular fibrillation, pheochromocytoma, and hypovolemia. Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia, with a lifetime risk in the community of 25% 1 and associated complications of heart failure, stroke, and death. Ventricular fibrillation c. Pulseless ventricular tachycardia .

Electrocardiograms revealed multifocal ventricular ectopy, and in two (4 and 10 yr old), this correlated with repeated administration of epinephrine during repeated ventricular tachycardia and ventricular fibrillation cardiac arrest resuscitation cycles. The lower second dose is due to the long half-life of amiodarone and the risk for toxicity if ROSC occurs. Another unique contraindication to be aware of is catecholaminergic polymorphic ventricular tachycardia. 8 Although VF appears as a chaotic and disorganized rhythm, characteristics of the ventricular fibrillation waveform such as . Off-label uses of epinephrine include, but are not limited to, ventricular fibrillation, pulseless ventricular tachycardia, asystole, pulseless electrical activity (PEA), croup, and severe asthma exacerbations unresponsive to standard treatment. Ventricular fibrillation (VF) begins as a quasiperiodic reentrant pattern of excitation in the ventricles with resulting poorly synchronized and inadequate myocardial contractions. The video below shows an example of what ventricular fibrillation will look like when you see it on the defibrillator monitor. Defibrillation is the treatment of choice and should occur as soon as possible. VENTRICULAR fibrillation, usually a rapidly fatal arrhythmia, occurs most commonly in coronary-artery disease, in patients with atrioventricular block (that is, Stokes-Adams disease) and in toxic r. ventricular fibrillation if used in the treatment of anesthetic cardiac accidents. 2, 3, 4 As a comorbidity of aging, preexisting AF is common among patients presenting to the ICU. CONTRAINDICATIONS Epinephrine. High quality CPR is in progress, and shocks have been given. . . 1:10,000 1.0 mg IV/IO; repeat q 3- 5 minutes; If VF/VT persists after three defibrillations or recurs: Amiodarone. 2.10-Ventricular Fibrillation/Pulseless V -Tach Patient with Cardiac Arrest and VF or VT on Presentation . Epinephrine may produce ventricular arrhythmias in patients who are on drugs that may sensitize the heart to arrhythmias. The endogenous release of epinephrine and other catecholamines is reported to increase 20 to 40 times when persons are subjected to different kinds of stress. An antiarrhythmic drug was given immediately after the third shock. We suspect that the β-adrenergic receptor activity of epinephrine attenuated hypoxic pulmonary vasoconstriction. Which drug and dose should be administered first by the IV/IO route? Lidocaine is one of several ACLS drugs used to treat cardiac arrest from ventricular tachycardia (VT) and Ventricular Fibrillation (VF). Contraindications Epinephrine is contraindicated in patients with known hypersensitivity to sympathomimetic amines, in patients with angle closure glaucoma, and patients in shock (nonanaphylactic). Off-label uses of epinephrine include, but are not limited to, ventricular fibrillation, pulseless ventricular tachycardia, asystole, pulseless electrical activity (PEA), . All these drugs are contraindicated in cases of rapid ventricular arrhythmias. Other Patients and Diseases Epinephrine should be administered with caution to patients with hyperthyroidism, diabetes, elderly individuals, and pregnant women. Contraindications that apply to both aspirin and clopidogrel include: Select one: a. Epinephrine is inactivated by alkaline solutions never mix with Sodium Bicarbonate. Sodium bicarbonate will inactivate catecholamines . sensitize the myocardium to the action of intravenously administered epinephrine or norepinephrine. • Proceed with Automated Defibrillator Procedure An arrhythmia known as ventricular tachycardia can cause ventricular fibrillation in some settings, but ventricular tachycardia is not an irregular heart rhythm, and very uncommon in healthy hearts. If ventricular fibrillation was secondary to degeneration of another arrhythmia that may recur, medication and other therapies (eg, radiofrequency catheter ablation [RFCA], pacemaker placement, automatic ICD [AICD], surgery) may be aimed at prevention of that arrhythmia. After 20 minutes, spontaneous circulation returned and she was transported to a local hospital. Conclusions During experimental ventricular fibrillation and CPR, epinephrine increased intrapulmonary shunt ≈300% more than saline or methoxamine and significantly reduced arterial oxygen saturation. Lidocaine is considered a second-line antiarrhythmic drug and should be administered in VF/VT cases where amiodarone is either unavailable or ineffective. Increase the force of contraction.
