key points to remember Flashcards
electrolyte abnormality in CAH
- metabolic acidosis
- hyponatraemia
- hyperkalaemia
- raised 17 hydroxy progesterone
electrolyte abnormality in bartter syndrome
- metabolic alkalosis
- hypokalaemia
- hyponatraemia
- hypochloraemia
- high calcium in urine
- high renin and aldosterone (normal bP)
management of bartter syndrome
- sodium chloride and potassium supplements
- indomethacin
difference between type 1 and 2 RTA
type 1 = distal = urinary ph >5.5 reduced bicarb, acidosis
type 2 = proximal = urinary ph <5.5
electrolyte abnormality in tumour lysis syndrome
- hyperkalaemia
- high uric acid
- high phosphate
- low calcium
- metabolic acidosis
oxygen and CO2 dependent on with ventilator settings
CO2 -> minute ventilation -> increase RR or PIP or tidal volume to clear cO2
O2 -> mean airway pressure -> increase PEEP to increase O2
stages of periventricular haemorrhage
1 - haemorrhage in germinal matrix
2 - IVH without dilatation
3- IVH with ventricular dilatation
4- IVH with intraparenchymal haemorrhage
