What are the indications of atropine?
Indications
- Antisialagogue. While atropine can be used independently for anti-salivation effects, it most commonly is secondary to anticholinergic or antimuscarinic poisoning, as discussed below.
- Anticholinergic Poisoning.
- Bradycardia.
- Rapid Sequence Intubation (RSI) Pretreatment.
What is atropine used for cardiac?
The use of atropine in cardiovascular disorders is mainly in the management of patients with bradycardia. Atropine increases the heart rate and improves the atrioventricular conduction by blocking the parasympathetic influences on the heart.
What is the drug atropine used for?
Atropine is a prescription medicine used to treat the symptoms of low heart rate (bradycardia), reduce salivation and bronchial secretions before surgery or as an antidote for overdose of cholinergic drugs or mushroom poisoning.
Is atropine used for myocardial infarction?
Atropine is the drug of choice for management of patients with SB and hypotension and is effective in the treatment of ventricular arrhythmias as well as conduction disturbances in patients with inferior myocardial infarction.
What is atropine used for in an emergency?
It is used in emergency situations when the heart beats too slowly, as an antidote to for example organophosphate insecticide or nerve gas poisoning and in mushroom poisoning. It can be used as part of the premedication before general anaesthesia.
Why would you give atropine?
Atropine is used to help reduce saliva, mucus, or other secretions in your airway during a surgery. Atropine is also used to treat spasms in the stomach, intestines, bladder, or other organs. Atropine is sometimes used as an antidote to treat certain types of poisoning.
Does atropine cause pupil dilation?
Conclusion: Atropine administration in conventional dose causes slight pupillary dilation but does not abolish pupillary light reactivity.
When should you give atropine?
Atropine is useful for treating symptomatic sinus bradycardia and may be beneficial for any type of AV block at the nodal level. The recommended atropine dose for bradycardia is 0.5 mg IV every 3 to 5 minutes to a maximum total dose of 3 mg.
What is the action of atropine?
Atropine reduces secretions in the mouth and respiratory passages, relieves the constriction and spasm of the respiratory passages, and may reduce the paralysis of respiration, which results from actions of the toxic agent on the central nervous system.
Why atropine is contraindicated in myocardial ischemia?
Atropine should be used with caution during AMI because the drug can potentiate dysrhythmias. In addition, the increase in heart rate caused by atropine increases the oxygen demand on the heart and can exacerbate myocardial ischemia.
Why is atropine contraindicated in heart block?
When the vagus nerve is blocked, the SA node increases its rate of electrical discharge and this, in turn, results in the increased HR. Use atropine cautiously in the presence of myocardial ischemia and hypoxia because it increases oxygen demand on the heart and can worsen ischemia.
Are there any side effects to taking atropine?
Adverse reactions to atropine may occur, and are of two types: toxic and allergic. Toxic reaction, the most common form, results from the anti-muscarinic effects of the drug. Since it is most probably related to interpersonal variation in sensitivity to atropine, toxic effects may appear at the usual therapeutic doses.
When to take atropine intravenously or by intravenous?
If there are local symptoms to the eyes or respiratory tract, atropine is not indicated. Intravenous (IV) atropine indications include patients with hypersalivation, bronchial secretions, or bradycardia. Large doses and repeat doses may be required. Ingestions especially require higher doses (up to 20 mg).
Is it safe to take atropine in pulseless patients?
The AHA has removed all indications for atropine in the pulseless patient. Atropine is not indicated in beta-blocker-induced bradycardias or hypotension, though its use is unlikely to be harmful. Glucagon is the first-line to treat beta-blockade-induced symptoms.
How many mg of atropine do you need for bradycardia?
Intravenous (IV) atropine indications include patients with hypersalivation, bronchial secretions, or bradycardia. Large doses and repeat doses may be required. Ingestions especially require higher doses (up to 20 mg). Titrate to effect by monitoring the patient’s ability to clear excess secretions.
