Just a quick question, do any CRNAs/MDA know why bolusing of pressors is sometimes done during surgery for a low b/p? My understanding of this practice is that it can cause a sudden rise is SVR and B/P, then the patient may again vasodialate and drop their B/P once the medication wears off. I have seen done on several occasions.

many times during surgery your transient drop in bp is just that -- transient...usually due to the anesthetics we give...so by giving a bolus - we maintain a satisfactory MAP - yet the med won't last 12 hours (when their BP will be back to normal by its own mechanisms.)
hope that helps...i could give you scientific jargon...but that is the down and dirty.
