For those who do there own flushing/lavage were do you get your catheters from and how do you sterilize or clean. Do they make single use?

Thank you

If you are talking about the pipettes you can get them from any company that carries AI equipment. I have never seen one that was to be cleaned and reused.

Do you use the AI pipette for flushing/lavage or antibiotics infusions as well as for AI

We like the silicon 34 French Foley catheter from Har-Vet or Exodus Breeder's Supply. The advantage of the silicon Foleys is that although more expensive, they can be steam-sterilised. This can be achieved in an autoclave, or even in a pressure cooker at a pinch!

We need to clarify carefully here the difference between infusion and lavage (commonly referred to as "flushing"). Insemination of semen or infusion of antibiotics into the uterus makes use of a pipette. A lavage - where fluid is introduced into the uterus, but then drained out again mechanically, typically using gravity - makes use of a catheter. Big difference! :-)

The vet I use uses the pipette for both. It may not be the correct piece of equipment to use but he does.

You cannot get an adequate cervical seal nor adequate in/outflow using a pipette. One ends up with leakage into the vagina (which isn't what one is lavaging) and you can't get any larger chunks of matter out of the uterus, which is what you really want out. In other words, you are quite probably paying for a service that you are either not getting or not getting effectively. I hope the cost is cheap...

Jos I understand what you are saying. I don't know what he charges as I have never had the procedure done just saw the procedure on mares while I was there. Infused the fluid and lowered the bag to have it refill.
I do have to ask though. When a mare is flushed (fluid left to expel on its own or with oxytocin) does the fluid not pass back through the cervex into the vagina?

Lavaging ("flushing") involves introduction of a larger amount of fluid than does infusing. With lavaging the intent is to encourage the return of all the fluid - or should be - hence the use of a larger bore tube and the suction effect of lowering the attached bag or the end of the tube. A sterilised stomach tube is often used if a Foley is not available for some reason.

The fluid in a lavage should pass back out through the cervix and through the vagina. One problem that can be encountered with placement of the fluid and not arranging recapture is with mares that have a cervix that does not relax - obviously those mares are going to have a harder time of eliminating the fluid.

Infusing (with a lower volume) typically will involve the use of an antibiotic or antimycotic to treat an endometritis situation and in that case, the fluid is left in the uterus and while some of it will find it's way back onto the vagina, the volume used is smaller (typically <100 ml) and it is the agent within the fluid that is important, and that is absorbed by the uterine tissue to some extent, or has an impact on the surface presence of the pathogen prior to being expelled.
