When do you conisder fundolipication
Persistent FTT Oesophagitis Aspiration
26
Complications of reflux
``` Distress FTT Aspiration Otitis media Dental erosion ```
27
What is Sandifer
Reflux Dystonia Torticollis Refer as Dx could be West syndrome
28
Ddx reflux
CMPI | Think if poor response or atopy
29
Feeding advice in reflux?
150ml/kg/day Position Routine
30
What are complications of surgery
Bloating Dumping Retching
31
What is CMPI / lactose intolerance
Delayed non-Ige reaction to milk (intolerance) Usually present first 3 months in formula fed (can occur in breast) If IgE would be immediate (known as allergy) Can get anaphylaxis / angiooedema but rare
32
How does CMPI present
``` Reflux symptoms don't improve - Regurgitation + vomit - Wheeze - Chronic cough Skin involvement Gut involvement ```
33
Signs of skin involvement
Rash Ectopic eczema Urticaria FH atopy
34
Signs of gut involvement
``` D+V - osmotic Blood / mucous Frequent runny stools Abdo pain Distension Poor feed FTT ```
35
Who is at risk of CMPI
Formula fed babies | FH atopy
36
How do you Dx CMPI
Clinical Eliminate diet Skin prick can be done
37
When do you investigate further
Bile | FTT despite change in milk
38
What should you do before leave hospital
Milk challenge as anaphylaxis can rarely occur
39
How do you treat
4 week milk avoidance Continue breast but eliminate cow from diet Calcium supplement
40
What is 1st line and what do you do if doesn't work
Highly hydrolysed cow milk protein - protein broken down | AA if severe colitis
41
What should you do regularly
Rechallenge | Milk ladder approach - cooked milk in biscuit then yoghurt then milk
42
What should you suspect if dehydrated
Obstruction as CMPI doesn't cause
43
DDX
``` Reflux Coeliac - not if baby Cows milk allergy - no allergic / skin symptoms (will still grow if have milk will just feel sick) Pyloric stenosis NEC Surgical Infection - culture? ```
44
What is NEC and what are RF
``` Inflammatory bowel necrosis common in pre-term Necrosis can lead to bowel perforation, peritonitis and death - Pre-term - LBW - Enteral feeding - Formula feed - Resp distress - Sepsis ```
45
How does NEC present
``` Poor feed Abdo distension Bloody / mucous stool Lethargy Vomiting bile Sepsis Vital signs instability Absent bowel sounds Rapid progression ot shock requiring mechanical ventilation ```
46
How do you Dx NEC
``` FBC, CRP Blood gas Stool and blood culture X-match blood AXR ```
47
What does AXR show
``` Asymmetrical dilated bowel Bowel oedema Pneumatosis intestinalis - gas in gut wall Free air Pneumoperitoneum ```
48
What is Rx
``` Stop feed + NBM NG IV fluids TPN if long term Ax as risk of perforation Surgical laparotomy if perforate / to remove necrotic bowel May need resection + stoma ```
49
What Ax
Amoxicillin Metronidazole Gentamicin
50
If pre-term what do you do prophylaxis
Careful introduction of food | Breast milk protective
51
What are complications
``` Shock DIC Perforation Peritonitis Stricutres Abscess Long term stoma Short bowel syndrome ```
52
DDX
CMPI Hirschprung Volvulus
53
What is pyloric stenosis
Pylorus muscle hypertrophies at 6 weeks
54
How does it present
``` Projectile non bile vomit 30 mins after feed No bowel Sx Palpable mass Visible peristalsis Constipation Dehydration Weight loss FTT ```
55
RF
6 weeks Male FH
56
How do you Dx
USS - olive shape mass U+E = hypochlorameia / hypokalaemia alkalosis Test feed
57
How do you treat
IV fluid to correct electroylte NBM and NG to remove acid Pyloromytomy when biochemistry improves
58
Why alkalosis
Lose HCL in vomit Lose K to keep H Increased bicarb
59
Complications
Dehydration
60
What is intussusception
Invagination of one portion of bowel into adjacent | Commonly ileo-caecal
61
How does it present
``` Hx viral illness Intermittent colic or crying Drying spell due to vagal - floppy / apnoea Abdo distension Loose frequent stool Billious vomit Toxic / irritable Blood / mucous PR Mass RIF Long cap refil Not always bilious / blood ```
62
Who is at risk
Toddler 6-18 months Older tha DIC
63
How do you Dx
USS = target mass 1st line AXR rule out obstruction CT / bowel enema
64
How do you treat
Pneumostatic reduction urgent under radiological guidance = 1st line Barium enema
65
What do you do if fails
Laparotomy if fails or peritonitis
66
What are complications
Dehydration Obstruction Necrosis of bowel
67
DDX
Gastroenteritis | Sepsis
68
What gives you clue to Dx
Lack of fever | Immense frequent stools
69
Where does malroation occur and what does it present with
High caecum Bile vomit Volvulus = scaphoid
70
RF
Newborn but any age Diaphragmatic hernia Duodenal atresia Exomphalos
71
How do you Dx
Upper GI contrast study and USS
72
How do you Rx
Laparotomy | Ladds if volvulus
73
Complications
Obstruction Peritoneal signs Instability
74
What is another cause of vomiting
Cyclical N+V lasting hours to days Well in between May be associated with weight loss, poor appetite, diarrhoea, abdominal pain, headache, dizzy, photophobia
75
How do you Dx and Rx
``` Clinical Blood tests to rule out Pregnancy in young women Avoid triggers Fluid Medication ```
76
How does duodenal present
Few hours after birth Billious vomitnig Down = increased risk AXR = double bubble sign
77
If child comes in vomiting

What should you do
FBC to look for anaemia | Coeliac screen + IgA
