Paediatric

Gastroenteritis (including campylobacter enteritis)

  • Majority of cases of acute gastroenteritis require NO antibiotic therapy.
  • Rehydration and electrolyte replacement (oral rehydration solution e.g. dioralyte) is preferred. For more information on fluid management, refer to NICE guideline C684.
  • If C diff is suspected, refer to Clostridioides difficile Infection guideline
  • For information regarding infection prevention and control, see ‘Gastroenteritis at-a-glance
  • Complete the notification form immediately on diagnosis of a suspected notifiable disease. See Notifiable diseases section for more information.
  • Obtain a detailed travel history and any history of immunosuppression.

Indication for antimicrobials

Do not routinely give antibiotics to children with gastroenteritis. Seek advice from Paediatric ID/Micro about giving antibiotic treatment to children:

  • with suspected or confirmed septicaemia
  • with extra-intestinal spread of bacterial infection
  • younger than 6 months with salmonella gastroenteritis
  • who are malnourished or immunocompromised with salmonella gastroenteritis
  • who have sickle cell disease with salmonella gastroenteritis
  • with giardiasis, dysenteric amoebiasis or cholera
  • with severe dysenteric shigellosis
  • with severe campylobacteriosis (see treatment below) 

Campylobacter enteritis

Usually self-limiting. NO antibiotic treatment usually required. ONLY treat if patient is immunocompromised. 

In cases of severe infection, discuss with Paediatric ID/Micro.
