− | ==Signalment==
| |
− | Foals younger than 6 months on a poor worming schedule and with a heavy parasite burden. Recent history of being wormed with a product that causes sudden ascarid death.
| |
− | | |
− | ==Aetiology==
| |
− | | |
− | ''Parascaris equorum''
| |
− | | |
− | | |
− | ==Clinical Signs==
| |
− | *Acute onset colic after administration of anthelmintic (onset varies with degree of obstruction (37))
| |
− | *Signs compatible with small intestinal obtruction
| |
− | **Nasogastric reflux (occasionally dead parasites are seen in reflux)

− | ==Diagnosis==
| |
− | | |
− | *History
| |
− | *Clinical signs referable to smal intestinal obstruction
| |
− | *Abdominal imaging (radiography and ultrasonography) may demonstrate multiple loops of distended small intestine, but imagin is not required if the clinical presentation indicates immediate surgery.

− | ==Prognosis==
| |
− | | |
− | ==Treatment==
| |
− | *[[Colic, Medical Treatment|'''Medical treatment:''']] immediate treatment of hypovolaemic shock resulting from sequestration of fluid in small intestine
| |
− | *'''Surgical treatment:''' enterotomy made over the intraluminal impaction and removal of ascarids
| |
− | | |
− | ==Prognosis==
| |
− | Fair in cases that are rapidly treated but poor in foals with evidence of hypovolaemia and septic shock. In a recent study, long term survival of 25 affected horses was 33%(37).
