Can you give nitroglycerin subcutaneous?

Can you give nitroglycerin subcutaneous?

In conclusion, our study suggests that subcutaneous injection of nitroglycerin at the radial artery puncture site can be a safe, economical, and effective approach to reduce the incidence of RAO post transradial coronary catheterization.

What is the difference between nitroprusside and nitroglycerin?

Nitroprusside is a potent arterial and venous vasodilator. It produces more balanced arterial and venous dilation compared to nitroglycerin (which is more of a venodilator particularly at low doses).

Can you give heparin intra arterial?

Some operators administer heparin through the intra-venous route while others use the intra-arterial route. One study has shown no significant difference in the rate of radial artery occlusion between the two routes [6].

How do you prevent radial artery spasms?

Radial artery spasm occurs frequently during the transradial approach for coronary catheterization. Premedications with nitroglycerin and verapamil have been documented to be effective in preventing radial spasms.

Is Nitro an arterial vasodilator?

Nitroglycerin is a vasodilator with multiple uses in the cath lab. It is administered via the intra-arterial route to relieve coronary spasm and prevent spasm from intracoronary tools such as intravascular ultrasound catheters or coronary wires.

Does nitroglycerin lower blood pressure?

Nitroglycerin works by relaxing smooth muscle within the walls of blood vessels (particularly veins) which dilates (widens) them. This helps to relieve chest pain that is caused by a narrowing of the blood vessels, and also reduces how hard the heart has to work to pump blood around the body, reducing blood pressure.

Why are drugs not given by an intra-arterial route?

Intra-arterial drug injection may cause vessel injury by one of several mechanisms. The vessel may be obstructed by inert particles or drug crystals. Hemolysis, platelet aggregation, vasospasm and venous thrombosis are the other contributory factors [2].

How is intra-arterial administered?

What is intra-arterial chemotherapy? Traditional chemotherapy is administered through a catheter into a peripheral vein. This means the chemotherapy drug has to pass via the heart and lungs before being delivered to the cancer, and therefore the drug is diluted by the time it reaches the target.

Why is verapamil given in the cath lab?

Background. Verapamil is traditionally applied prophylactically in transradial procedures to prevent radial artery spasm. However, verapamil may have side effects and is contraindicated in some clinical settings.
