Did she only have the meds the Vet administered yesterday- ie you were given nothing to continue her treatment at home ?
With gut stasis treatment needs to be ongoing, so Metoclopromide is usually given every 6-12 hours, Ranitidine (Zantac) every 12 hours. Analgesia also needs to be maintained, frequency of dose and type of drug will vary. Ongoing SQ fluids are very helpful, dehydration of ingesta occurs rapidly when gut motility is reduced. This just exacerbates problems. Oral fluids remain important too.
In some cases Lactulose, an osmotic Laxative can be useful
Exercise and abdominal massage is often helpful, but abdominal massage should not be attempted without specific Veterinary advice/guidance
Maybe the Vet could admit Emmy for ongoing intensive care ?
