session 9 Management of paediatric dehydration Flashcards
explain the clinical signs of dehydration in an infant and child
sunken eyes dry mucous membranes reduced urine output poor skin turgor cool peripheries lethargic grey motttled skin colour sunken fontenelle in babies up to 11-15mths
describe how to calculate fluid requirements for an infant or child
none: 3-5 % = 50mls/kg
some: 6-19% = 60 - 90 mls/kg loss
severe: >10% = 100 mls/kg loss
a child was estimated to be 5% dehydrated. They were weighed yesterday before they got sick as 8 kg. What is their estimated fluid replacement need?
50x8=400mls
over 4 hrs = 400/4 =100mls hr
what are signs of hypvolaemic shock
tachycardia
hypotension
reduces level of consciousness
what is the treatment for hypovolaemic shock
fluid bolus - 10ml/kg 0.9% normal saline
repeat 10ml/kg 0.9 % normal saline
maintenance fluid commenced
why is it dangerous to give lemonade to a dehydrated child?
Osmosis - draws water away from cellular volume and the child can go into hypovolaemic shock
How do you assess for dehydration
Weight vital signs - character of pulse thirst LOC skin turgor, cap refill, temp mucous membranes fontonelle eyes urine output urinalysis electrolytes/ acid base balance
what are the principles of nursing care for the child with body fluid and electrolyte imbalance from acute gastroneteritis
Daily weights strict Fluid balance weigh nappies impaired skin integrity related to the presence of diarrhoea BGL , postassium and sodium monitoring promote comfort family support antiemetics NGT or IV cares WASH HANDS post care
what is normal urinary output for an infant and a child
2mL/kg/hr for an infant
0.5 mL to 1 mL/kg/hr for children
What other electrolyte imbalance occurs from metabolic alkalosis due to vomiting displayed in gastroentetitis
Vomiting causes a loss of hydrochloric acid from the stomach leading to metabolic alkalosis - a secondary electrolyte problem occurs from this - hypokalaemia (low potassium).
what is the 3 step process to interpreting blood gases
step 1 - Look at pH (normal 7.35-7.45)
step 2 - look at CO2 (normal 35-45 mmHg)
step 3 - confirm by checking the base excess of bicarbonate (normal +/- 2)
