Zosyn over 4 hrs

Nurses Medications

Published

At my hospital we used to infuse Zosyn (2.225, 3.375, and 4.5GM) mixed with 50mL of NS over 30 minutes. Recently our hospital has changed protocol to infuse 3.375GM with 100mL of NS over 4 hrs. At first it was just for renal patients with off the wall BUN/Creatine levels, now it is protocol for every patient receiving Zosyn. They say that the therapeutic levels stay in the system longer. I like to verify things myself, but after consulting Almighty Google, I am having trouble finding any science behind this. It makes sense to me, but I just like seeing the data for myself. I am weird.

Anybody heard anything about this?

We do the same at our hospital also. I found the following research point slide,

Hope it helps.

No matter the concentration (2.225, 3.375, or 4.5GM) the order always states to give Zosyn over 30 minutes, even with renal patients. Frequency is usually Q6H or Q8H.

One of my coworkers the other night had a pt that had a continous Zosyn infusion. As it wasn't my pt, I don't know all the details, but she's a new grad and asked me if I'd ever heard of that. From what I understand, it was dose of 13.5grams infused over 24 hours and then started all over again. This was a Lung Ca/Breast Ca pt with mets; however was at our facility with UTI/Sepsis and had drains everywhere.. JP for the cancer to the breast, 2 chest tubes (one on either side) a Mediport and double lumen PICC line, as well as high flow O2, Foley cath, and PCA hooked up. Really, she was probably too high acuity for our floor, however the ICU was full so we ended up with this pt.

Sorry for the long message- this is from IB Micromedex, I could not send a link since you have to subscribe to this service. I only searched the compatible and caution variable i.e. vanco up to 1 Gram is compatible with 3.375 d/t the ratio however 1500 mg vanco is not compatible. hope this helps!

General Dosage Information

compared to standard intermittent-infusion therapy, piperacillin/tazobactam administered as a continuous (initial bolus of 2 g/0.25 g infused over 30 minutes, then 12 g/1.5 g over 24 hours [1]) or prolonged intermittent infusion (3.375 g over 4 hours every 8 hours [2][3]) achieve higher pharmacokinetic and pharmacodynamic targets, but may only be associated with improved clinical outcomes in critically ill patients [4]
