Terbutaline is an IV B2 agonist, is it not?

Seems it's main use is keeping the bun in the oven though.

Not according to my pharmacology text, but what do text writers know ;)

Yea, that sounds like a good idea. Which one are you referring to? A page # would also help expidite the search for this b2 selectivity of epinephrine. A preliminary search for this selectivity has yielded me nothing, but my only source available to me is the world wide web, (all my texts are at home :crying2: ). AND, as we all know, the web can be as reliable as overhearing a conversation in the bathroom so to speak, but I digress.

Take it easy on me, I'm still learning, but very interested. Have a good day!

Acetylcholine is a bronchconstrictor so giving pre-op atropine or glycopyrolate decreases intra-op bronchospasm. These are effective IV, IM, or endotracheally.

Terbutaline (Brethine) is one of the first bronchiodilators (sorry, I don't feel like thinking about the spelling).

It has been replaced with newer (better) meds and is now primarily used to stop PTL.

My mom was severely asthmatic (with a strong emotional component) and had PTL . She credited Brethine for my existance.

NO does help with hypoxia by limiting the lungs' vasoconstrictive response to hypoxia. I think it relaxes the vascular endothelium and dilates the pulmonary vessels.

I do remember that long term NO therapy oxidizes iron and causes methemoglobinemia, which inhibits the blood's oxygen-carrying capacity.

These are the only things I can remember about NO in regards to the respiratory system.
