I will check first thing in the morning again. If need be, I will call the vet for yet another after hours call <sigh> of course this would happen over Easter weekend...
Anyway, here are two pictures for you to have a look at. There is no heat, no swelling, no pooling. There is some extra "shinny-ness" here aside from the drainage because I put polysporin on the drain exit. That was when I noticed that my finger came away with a slightly orange colour on it.
History is below the pictures if you care to read it, but is not necessary, IMO.
Here is Lisa aka "Hose-head" Lisa-head-bonk-005.jpg
... and a close-up: Lisa-head-bonk-005-close-up.jpg
Tuesday evening, Lisa decided to back out of the trailer when she wasn't supposed to. I told her not to, pulled on the lead and she threw up her head and bonked it.
Damage is only to soft tissue. The vet did her thing: cleaned, sedated, local freezing, tetanus, bute, penicillin. She is on bute for one more day and penicillin for a total of 5 - 7 days (3 - 5 more). There was a large area of the skin that lifted and developed a pocket where fluids could build up, hence the drain tube. Polysporin is applied daily to the entrance and exit areas for the drain tube.
She is an outside horse. The vet was told this and understood. Lisa has a modified fly mask on to protect the area.
Vet's prognosis for adherence is pessimistic because the cut is downward. Of course, the main concern is infection.
