Vomiting

Nota:

• -common chronic causes= GORD, feeding probs (force-feeding or overfeeding) -if transient, w/ other sx e.g. fever, diarrhoea, runny nose and cough- most likely gastroenteritis or RTI, but consider UTI and meningitis -if projectile at 2-7 weeks old, exclude pyloric stenosis -if bile stained vomit, exclude intestinal obstruction, esp intussusception, malrotation and strangulated hernia. Assess for dehydration & shock.

1. forceful ejection of gastric contents
2. differs from
   1. non-forceful return of milk
      1. regurgitation
         1. larger, more frequent losses
      2. posseting
         1. small amounts of milk w/ return of swallowed air ('wind')
3. red flag clinical features in vomiting child
   1. bile stained vomit (dark green)
      1. intestinal obstruction
         1. if more proximal
            1. vomiting is more prominent
            2. vomit becomes bile-stained sooner (unless obstruction prox to ampulla of Vater)
   2. haematemesis
      1. oesophagitis
      2. peptic ulceration
      3. oral/nasal bleeding
   3. projectile vomiting in 1st few weeks of life
      1. pyloric stenosis
   4. vomiting @ end of paroxysmal coughing
      1. pertussis
   5. abdo tenderness/abdo pain on movement
      1. surgical abdomen
   6. abdo distension
      1. intestinal obstruction, e.g. strangulated inguinal hernia
      2. more marked in distal obstruction
   7. hepatosplenomegaly
      1. chronic liver disease
   8. blood in the stool
      1. intussusception
      2. gastroenteritis

         2. Campylobacter
   9. severe dehydration, shock
      1. diabetic ketoacidosis

      3. systemic infection, e.g.
         1. UTI

   10. failure to thrive
       1. gastro-oesophageal reflux
       2. coeliac disease
       3. other chronic gastrointestinal conditions
   11. bulging fontanelle or seizures
       1. raised intracranial Pa
4. usually benign
5. often caused by feeding disorders or mild GORD or gastroenteritis
