The plunger part - opposite from the needle.

When you inject the lovenox you want the bubble of air to go in before the medication. So it means the air bubble is at the end closest to the needle.

The air bubble should be up at the plunger. The rationale is that the injection of the small amount of air after the medicine will ensure the entire volume is delivered to the patient.

Um... i thought you wanted the bubble to follow the med.. so that the incidence of bruising is decreased... pushing the med further into the SQ tissue.... ??

At least that was the reasoning i was taught... whatever the reason.. you want the bubble to go in after the med...

No, the air goes in first, the air helps to distribute the medication evenly into the subcutaneous tissue.

Re: Where should the BUBBLE Be

I just read the manufacturer's guidelines for administrating and the only mention of the air bubble is to not expel it before the giving the injection...it doesn't say that it should precede or follow the med. I was taught that it follows the med to ensure the whole dose is given.

I agree. Since I'm the only one saying the air goes in first, heck I may be wrong but I remember the first time I gave it, probably 5 years ago, the package insert said the air goes in first. I'll check on it and get back to you. Sorry for all the confusion.

I have always done the air last. All of my instructors made sure to remind us of that before we gave our lovenox injections. This helps to keep the med in the med in the subq tissue. I don't understand how injecting the air first would help prevent the loss of the med.
