Trying to debride such sensitive tissue without anesthesia would do more harm than good...She's already in some pain, the pain after debridement would make her expel her intestines, I am aware of a case like this, where just a well meaning but unnecessary cleaning with chlorhexidine of a mild prolapse resulted in the hen being in such pain that she strained so much, she expelled her intestines soon after. Also, there are reports of the necrotic tissue falling off by itself.
There is a narrow window of opportunity with every prolapse and exactly what is applied then
makes a world of difference and can result in three possible outcomes:
a. Complete cure
b. Partial cure, resulting in a 'leaky bottom'. This means that later on she could get salpingitis or flystrike. Even if treated, they will keep coming back because their cause will remain.
c. Crossing the rainbow bridge, as the OP poetically puts it
Just in the last few months, just on this site, confirmed deaths from Prep H (with or without lidocaine)

One report of cure with Prep H. An elegant explanation from
@NancyNurseCxMama why it shouldn't be used:
"After much research, I soaked her in an Epsom salts bath for about twenty minutes. BTW---Preparation H is no longer recommended. As a nurse I questioned the Prep H approach---this would restrict blood flow to the area. A prolapsed vent is inflamed displaced tissue and restricting blood flow would reduce the size of the prolapse but also deprive it of blood flow. Not good for healing. To restrict blood flow to the area would reduce its size but not address the issue which is the displacement of the vent."
Two deaths from vaseline cream:

Vaseline could be described as
neutral, won't actively harm, but won't actively help either. No report of cure in the same time period .
Hydrocortisone cream, the one that suppresses the immune system has one death

and one cure reported by
@NancyNurseCxMama
While searching for a cure, I've seen one recommendation to use sugar (and rinse it off 30 minutes later ?!!) and one report of someone who had used it, called it 'messy' and I must not have been impressed with the result because I kept searching. I would much prefer to use sugar than grind tree bark, of course, but sugar is no great astringent, actually it's not an astringent at all.
Supermarket honey has no medicinal properties. Raw, unpasteurized honey does have medicinal properties, just not an astringent..
Almost home now: cold pressed, unrefined coconut oil is antibacterial, anti-inflammatory, oily. Will do the job if it's a first or second prolapse, discovered soon after it happened. It's best to combine it with white oak bark powder, which is antiseptic and quite the astringent. In fact, calling white oak bark powder an astringent is like saying that the sea is wet.
The 'recipe' is dedicated to poor Ida (remember her?)
This little analysis is dedicated to the anonymous hen who died one week before I registered here at BYC.
