How does terbutaline work for priapism?

The mechanism of action of terbutaline in erection is poorly understood. Although it acts as a β-2-agonist and smooth muscle relaxant, the stagnant blood in priapism would impede perfusion of the terbutaline into the corpus cavernosum, suggesting an alternate means of effect, if any.

What injection is given for priapism?

Intracavernous injection: This treatment is used for low-flow priapism. Drugs known as alpha-agonists are injected into the penis. They cause the arteries to narrow, reducing blood flow to the penis and causing the swelling to decrease.

How do you give priapism to phenylephrine?

Phenylephrine should be diluted in normal saline to produce a concentration of 100–500 μg/ml. Then, injections of 1 ml aliquots should be performed intracavernosally every 3–5 min for up to 1 h or up to a dose escalation of 1000 μg of diluted phenylephrine [Montague et al. 2003].

Where do you inject priapism with phenylephrine?

Draw 0.5 mg of phenylephrine into a 27 gauge (G) syringe. Place the needle into the corpus cavernosum on the selected side, close to the base of the penis at the two or ten o’clock position. Aspirate a little to confirm that you are in the corpus, and then inject the phenylephrine.

How does phenylephrine help priapism?
