| − | ==Description==
| |
| − | '''Haemorrhagic gastroenteritis''' is characterised by acute [[Stomach and Abomasum Consequences of Gastric Disease - Pathology|vomiting]] and [[Intestine Diarrhoea - Pathology|diarrhoea]]. Gastrointestinal integrity is loss, resulting in a rapid movement of blood, fluid and electrolytes into the intestinal lumen. The aetiology is unknown but it may relate to ''[[Clostridium species#C. perfringens type A|Clostridium perfringens]]'' enterotoxicosis or an immune-mediated reaction. There is usually no history of garbage, chemical or foreign body ingestion.

| − | ==Diagnosis==
| |
| − | ===Clinical Signs===
| |
| − | *Acute and progressive haematoemesis and/or haematochezia, with [[Stomach and Abomasum Consequences of Gastric Disease - Pathology|vomiting]] preceding [[Intestine Diarrhoea - Pathology|diarrhoea]]
| |
| − | *Critically ill or moribund patient in severe cases
| |
| − | *Depression and anorexia
| |
| − | *Abdominal pain
| |
| − | *Dehydration and [[Patología General - Shock#Hypovolaemic shock|hypovolaemic shock]] occurs over a period of 8 - 12 hours.
| |
| − | *Pyrexia (rare)
| |
| − | *Thrombocytopaenia (severe cases)
| |
| − | *Pre-renal or renal azotaemia (severe cases)
| |

| − | ===Laboratory Tests===
| |
| − | ====Haematology====
| |
| − | *Haemoconcentration with PCV > 60%
| |
| − | *Normal or increased total protein concentrations, but proportionately lower than would be expected from the corresponding increase in PCV due to loss of protein through the intestines.
| |
| − | | |
| − | ====Other Tests====
| |
| − | *Faecal cytology may reveal red blood cells, occasional white blood cells, ''[[Clostridium species#C. perfringens type A|Clostridium perfringens]]'' spores or enterotoxin. ''[[Clostridium species#C. perfringens type A|Clostridium perfringens]]'' spores or enterotoxin can be found in a normal dog, therefore care has to be taken not to over-interpret this.
| |

| − | | |
| − | ===Diagnostic Imaging===
| |
| − | ====Radiography====
| |
| − | Abdominal radiograph may reveal fluid and gas filled small and large intestines.
| |
| − | | |
| − | ==Treatment==
| |
| − | *Start treatment prior to a full diagnostic investigations.
| |
| − | *Aggressive intravenous fluid therapy is important for the treatment and prevention of shock.
| |
| − | **[[Colloids|Colloidal]] or plasma are recommended to replace the intravascular deficit due to loss of protein, followed by [[Crystalloids|crystalloids]] to complete rehydration.
| |
| − | **Clinical improvements should be noted within a few hours but resolution of clinical signs may take a few days.
| |
| − | *A broad spectrum antimicrobials such as [[Penicillins|ampicillin]] combined with [[Fluoroquinolones|fluoroquinolone]] are appropriate against ''[[Clostridium species#C. perfringens type A|Clostridium perfringens]]''. This is recommended to be given empirically.
| |
| − | *Initially, Nil Per Os should be implemented. Once vomiting has stopped a bland and highly digestible diet such as chicken and rice can be introduced.
| |

| − | | |
| − | ==Prognosis==
| |
| − | Good if presented in a timely fashion. The duration of the disease is normally between 24 - 72 hours. Complete recovery in most cases provided there is no complication such as hypoproteinaemia or sepsis. However, recurrence is possible.
