Paed Surgery Flashcards
How would you determine the avg weight of a child if you don’t have time to weigh them?
2 x (age +4)
E.g. 10yr old: 2 x (10 + 4) = 28 kg
How do you determine blood volume, urine output and insensible fluid loss in kids?
Blood volume = 80ml/kg
UO = 1ml/kg/hr
Insensible fluid loss = 20ml/kg/day
How do we determine the systolic BP of kids?
80 + (2 x age)
E.g. 9yr old:
80 + (2 x 9) = 98
How do we manage pain in kids?
Follow the WHO pain ladder:
1) PM
2) Ibuprofen
3) Weak opiod (but codeine can’t be used <12yrs)
4) Strong opioid e.g. morphine
What would we give kids as resuscitation fluids?
20ml/Kg bolus of 0.9% NaCl (saline)
What do we give kids as maintenance fluids?
4ml/Kg (1st 10Kgs)
2ml/Kg (2nd 10kgs)
1ml/Kg (thereafter)
Of 0.9% NaCL & 5% dextrose +/- KCl
E.g. 10yr old = 28kgs
(4 x 10) + (2x10) + (1 x 8 ) = 68ml/hr
List 5 red flag signs of a surgical problem in kids?
- Feed Refusal

How do we manage someone with appendicitis?
Analgesia & Laparoscopic appendectomy
Non-specific Abdo Pain (NSAP) is a +Ve diagnosis for when we can’t find a pathological reason for abdo pain. What are it’s features?
Short Central Constant Not affected by movement No GIT disturbance No temp Site/severity changes
It’s more common in girls and is often recurrent
What is Mesenteric Adenitis
Lymphadenopathy in abdomen –> Abdo pain, tenderness & high fever
It’s caused by a precedeing viral illness e.g. URTI
How can pneumonia present with abdo pain?
