Vomiting in Childhood Flashcards
What are the different classes of vomiting (4)?
- vomiting with retching
- projectile vomiting
- bilious vomiting (red flag)
- effortless vomiting
What are features of vomiting with retching?
- pre-ejection phase (pallor, nausea, tachycardia)
- ejection phase (retch, vomit)
- post-ejection phase (pale and limp)
What can stimulate the vomiting centre?
- Enteric pathogens (tummy bug)
- Intestinal inflammation
- Metabolic derangement
- Infection anywhere in the body. E.g. meningitis, UTI, encephalitis, otitis media, chest infection, sepsis.
- Head injury (raised ICP)
- Visual stimuli
- Middle ear stimuli
What is pyloric stenosis?
congenital narrowing of the pyloric sphincter
How can pyloric stenosis present?
-young infant (4-12 weeks)
-non-bilious projectile vomiting (usually after feed)
-not gaining weight adequately
-dehydration
electrolyte disturbance (metabolic alkalosis, hypochloraemia, hypokalaemia)
How can you diagnose pyloric stenosis?
- do test feed and see visible gastric peristalsis (‘olive tumour’)
- US detection of long, thickened pylorus
- ABG - alkalosis
How can you manage pyloric stenosis?
- fluid resuscitation if dehydrated
- refer to surgeons (Ramstedts pyloromyotomy)
What colour is bile?
GREEN!!! (not yellow)
What is gastro-oesophageal reflux?
movement of gastric contents into oesophagus
How does GORD present?
- infants
- effortless vomiting (almost always caused by GORD)
- may be haematemesis
- feeding problems
- FTT
- respiratory symptoms because of aspiration
- neurological (Sandifer’s syndrome - abnormal movement of body to try and alleviate discomfort from GORD)
How should you assess a child you suspect to have GORD?
- history and examination often sufficient
- radiological investigations e.g. video fluoroscopy, barium swallow
- pH study combined with oesophageal impedance monitoring (gold standard)
- endoscopy (chid >2years or have symptoms of pain or difficulty swallowing)
Why would we consider a barium swallow to identify GORD?
may show:
- dysmotility
- hiatus hernia
- reflux
- gastric emptying
- strictures
What treatment can be offered for GORD?
- feeding advice - thicken the feed (as can help keep the feed down-may use gaviscon or ‘thick and easy’) and position baby at 45 degrees while feeding and prop up baby to sleep at 45 degrees
- nutritional support (some may require NG tube if continue to have large vomits), calorie supplements, exclusion diet (milk free) if not getting better
- medical treatment e.g. PPIs, H2 receptor blockers
- surgery - fundoplication
What are indications for surgery for GORD?
- FTT
- aspiration pneumonia
- oesophagitis
What can cause bilious vomiting?
- intestinal atresia (In newborn babies only)
- malrotation with or without volvulus
- intussusception (toddlers)
- ileus (older child)
- Crohn’s disease with strictures (older child)
