Can't say anything like that has happened to me but I do often get an air lock effect in the pouch outlet or the night bag connector so that it doesn't drain from one to the other. It's more troublesome with some particular sorts of pouches and bags but far less so with others but is really aggravating if you're sleepy in bed and go to hook up and then have to get up and jump up and down or waggle things around for a few minutes to free the flow. I often wake up in the night to find it's jammed up again and my pouch is full so have to stand up and shake it all about again.
It's all good, eh?
I have asked for an answer in the past but was unable to get a straight answer or a cure.
Trying to work out how the heck you get air in a Uro bag ????
The only time I have had excess air in my night bag is if I've cleaned it with something that creates froth and not made sure it's drained properly afterwards. Even so it's just a little bit bulgy above the top of the liquid...
I don't know what happens to the air during the day but I have never had any problem in that respect. Just as a matter of interest it has happened with both new and old washed night bags.
Almost from the beginning of using a night bag for my Urostomy, I found the bag has ballooned with air in the morning (I was afraid the pressure of the air can break the bag and…).
I didn’t find any reference to this occurrence in Google, except for two similar complaints in another forum.
I looked for all kind of explanations (more or less fantastic J), until I realize that the small bag attached to the base of the stoma (Hollister, 2 parts) during the day, didn’t suffer from the same phenomenon.
In other words, something in the night bag….
Since the beginning of my treatment I have been rinsing the night bag in the morning with diluted vinegar (acetic acid), leaving a small amount in the bag when I re-connect again at night (I change the night bag once a week).
Normally in the urine, there is a salt called calcium carbonate (and the amount can be relatively excessive when the ostomate suffers from a specific kind of excessive acid in the blood, a known complication of the ileal conduit (usually very mild and asymptomatic). The excess of acid is buffered (lessened) in part by extracting calcium carbonate from the main deposit of this salt in the body, the bones (and finally eliminating it in the urine). By the way, the presence of excessive calcium carbonate in the urine is one of the reasons for the frequent production of stones in the urinary systems of urostomates.
And here comes the solution to the “mystery”: the combination of acetic acid and calcium carbonate produces the gas CO2 (carbon dioxide), the same gas we exhale during respiration. For the chemistry-minded ostomates:
2CH3COOH + CaCO3 ----- Ca(CH3COO)2 + H2O + CO2
The night following my “discovery”, I connected to a new bag: no “air” in the morning. The same after rinsing the bag with vinegar, but afterward rinsing it again with water.
I think this is the mechanism for the production of nocturnal gas.
I suppose there are variables playing here, on the production of more or less (or none) gas: the use of vinegar, of course. Then, how much vinegar we leave in the bag. And finally, how much calcium carbonate the urine contains.
