Neosynephrine compatibility problem

phenylephrine is compatible with norepinephrine.

if you are still worried you can always put the diprivan with your crystalloid solution or heparin infusion.

Yeah, I usually run my pressors together...

I would start a separate line and run the Diprivan peripheral, as opposed to running the Neo peripheral....vasoactives are usually very harsh on peripheral veins and the chances of extravasaton or phlebitis is high....Diprivan is okay to run peripheral...and it's beter like the others said to run separate lines for your pressors and such.....

Why was D51/2 running wide open??? I don't think I have ever seen that....I have seen LR or NS full open....but dextrose full open isn't wise....

This can really cause some metabolic probs. in septic patients....and it is really hard on kidneys and brain tissue at a full on rate...

I wouldn't put a titrated drug into a line where it could be accidently bolused into the bloodstream via a fast running IV line, or a transduced line, like a cvp line....

I am curious about the primary IV rate, and why.....

I would probably start an A/C and run the D51/2NS via the PIV. We run propofol on a lumen by itself and I'd put the levo in another lumen.

Why does this pt. have D51/2NS wide open? What was wrong with this patient, or is it a hypothetical patient?

Thanks for all of your responses....

This was a hypothetical patient that my instructor came up with.

this may be a silly question, but if you have a triple lumen port, does EVERYTHING running through all three ports have to be compatible? Or say, can you run Neo through one port and Diprivan through another safely?

Most Infusion Therapy protocols are now adopting a heparin free protocol, because of the increased incidence of HIT and allergic reactions to heparin. You can infuse incompatible drugs IV through a central line concurrently, that is why a triple lumen was invented.

here is a good study done in vivo on just this subject, and the conclusion was that there was no evidence of precipitate or clogging problems as the above poster mentioned....

I have used T-lumens, Swans, Groshongs, Hickmans, etc. for my whole nursing career....and as long as you think before you plug in your drugs, you should do just fine....just don't run incompatibles IN THE SAME PORT...

Background:

Multilumen catheters are commonly used in critically ill children. Their use, however, is associated with significant morbidity. We studied the simultaneous administration of incompatible drugs using a new triple-lumen catheter with decreased length and port to port distances.

Methods:

Ten domestic swine, 10–20 kg in weight, were divided into two groups of five. Total parenteral nutrition was administered through the distal port and phenytoin was administered as a bolus and as an infusion in each group. Samples were taken from two sites during the bolus and at 1, 5, and 15 min during phenytoin infusion. Histograms were generated for particle size and concentration. Samples were also examined under the microscope for particles.

Results:

Histograms of particle size did not show any alteration of the histogram that would suggest particle size > 2 μm in diameter in the study or control samples. No particles were identified by phase microscope, light microscope, or Wright stain smear.

Conclusions:

The use of a triple-lumen catheter with a distance of 0.4cm between the proximal port and the medial port and 1.3 cm between the medial port and the distal port, for the in vivo simultaneous administration of incompatible solutions does not result in precipitates large enough to cause adverse clinical effects.

It is helpful to have some peripheral lines if possible, for the less abrasive IV solutions, ie a normal saline tko with maybe intermittent pushes and less caustic antibiotics....and leave the central line open for blood draws, TPN, and IV pressors or blood administration.

I hope this answers your questions....
