What is not safe for adenosine infusion?

Adenosine infusion is contraindicated in patients suffering from: – Hypersensitivity to the active substance or to any of the excipients listed in section 6.1. – Second or third degree atrioventricular (AV) block, sick sinus syndrome, except in patients with a functioning artificial pacemaker. – Long QT syndrome.

How does adenosine work?

Adenosine not only dilates coronary vessels, but attenuates beta-adrenergic receptor-mediated increases in myocardial contractility and depresses both sinoatrial and atrioventricular node activities. The effects of adenosine are mediated by two distinct receptors (i.e., A1 and A2 receptors).

How do you infuse adenosine?

Adenosine should be administered by rapid intravenous (IV) bolus injection into a vein or into an IV line. If given into an IV line it should be injected through as proximally as possible, and followed by a rapid saline flush. If administered through a peripheral vein, a large bore cannula should be used.

How does adenosine affect sleep?

During wakefulness, adenosine levels gradually increase in areas of the brain that are important for promoting arousal, especially the reticular activating system in the brainstem. 3 With higher and higher concentrations, adenosine inhibits arousal and causes sleepiness. Then, adenosine levels decrease during sleep.

How does adenosine make you sleepy?

Our neurons, or nerve cells, are embedded with adenosine receptors. When adenosine binds to these receptors, a variety of proteins that inhibit neurons are released. This suppression of nerve cell activity is what causes the feeling of drowsiness.

Does adenosine cause tiredness?

Adenosine is a chemical in the central nervous system. It regulates your sleep-wake cycle. When you’re awake during the day, your adenosine levels increase , eventually making you drowsy by suppressing the activity of cells in the basal forebrain.

What chemical makes you wake up?

Serotonin. Serotonin is an important chemical in supporting the process of waking you up and some wake-promoting serotonin cells are themselves sensitive to light.

How many milligrams of OxyContin are there?

OxyContin® (oxycodone hydrochloride controlled-release) Tablets are an opioid analgesic supplied in 10 mg, 15 mg, 20 mg, 30 mg, 40 mg, 60 mg, 80 mg, and 160 mg tablet strengths for oral administration.

Are there any side effects to taking adenosine?

Therefore, the lower dose (3mg) may be considered for patients with a central venous line or a history of heart transplant. Some side effects of adenosine administration include flushing, chest pain/tightness, brief asystole or bradycardia. Make sure that adenosine is not used for irregular, polymorphic wide-complex tachycardia and unstable VT.

What should be the initial dose of adenosine?

A lower initial dose of 3mg should be used for patients taking dipyridamole or carbamazepine as these two medications potentiate the effects of adenosine. Also, prolonged asystole has been seen with the use of normal doses of adenosine in heart transplant patients and central line use.

What are the risks of OxyContin extended release?

OxyContin exposes users to the risks of opioid addiction, abuse, and misuse. Because extended-release products such as OxyContin deliver the opioid over an extended period of time, there is a greater risk for overdose and death due to the larger amount of oxycodone present.
