Pedi 13 Flashcards
Pathogenesis of refeeding syndrome?
High insulin–Increase cellular uptake of K/Mg/P and thiamin–Low serum k/Mg/P and thiamine
High insulin also increases Na and Water retention
Manifestation?
Arrhythmia and CHF CNS(Seizure, Treamour..) Wernicke encephalopathy MSK(rhabdomyolysis and weakness) GI(diarrhea and elevated TA)
RTA type?
1–distal
2-proximal
4-aldosterone related
D/T based on urine PH and electrolyte(PH is >5.5 in 1 and <5.5 in 2 and 4), serum K high in 4, and low-normal in 1 and 2
CM of RTA?
Growth failure
Low bicarbonate
High serum chlorine(help to D/T from MA from Gi causea)
Non Anion GAP metabolic acidosis
T1RTA Cxs?
Poor H secretion in the distal nephron High urine PH Low-Normal serum K Medication disorder AID(SS and RA) Family Hx of nephrolithiasis
T2RTA?
Defect in proximal Bicarb absorbition
Low urine PH
Low-Normal serum K
Fanconi syndrome(Glucoseuria,Posphaturia and aminoaciduria)
T4RTA?
Aldostrone resistant/defect in k/Na antiporte in DCT
Urine Ph <5.5
High serum K
CAH and Obstructive uropathy
DPT component?
Diphtheria Toxoid
Tetanus Toxoid
Conjugated/acellular pertussis
Schedule?
6 dose
2,4,6 month
15-18 month
4-6 year
C/I?
in Px dose
EncephalopathyIAMS, Prolonged seizure, comma…)
Anaphylaxis
Unstable neurologic sign(uncontrolled seizure and infantile spasm)
Reactive attachment disorder (RAD) CM?
Occur in children with Hx of neglect/abuse/prolonged institutionalization and inconsistent care
Seldom need comfort
Do not respond to confrontation
Lack of social responsiveness
Lack of positive emotion
Unexpected irritability and sadness to non-treatning situation
What about PTSD?
No emotional stunning
No lake of response to the caregiver
Risk factor for methemoglobinemia?
Nitrates
Dapsone
Topical/Local anesthetic
CM?
Cyanosis
Dark checolate blood
Pulsosimetry–85%
LAB?
Normal Po2
>5% d/c in saturation by pulse oximetry and ABG
pathophysiology?
Oxidizing agents—Change Fe2+ to Fe 3+–Low O2 affinity and Deacrese 02 release from periphery–Hypoxia/Blood colour and cyanosis did not respond to 100 02 but ABG read normal o2
management?
Methylene blue(reduce MetHb to Hb) Vit C if MB not available or C/I(G6PDD)
Viral meningitis Cxs?
Viral predoom Meningeal sign CSF(WBC(10-500),G(40-70,I.e N) and P(40-150) Focal NS less likely MCC is Enterovirus
Enterovirus
part of picorena (NE,IS,SS,RNA) Poliovirus Echovirus, Coxsackievirus can cause aseptic (viral) meningitis
management?
Supportive
