Rx hyperkalaemia? (5)
|
Insulin + glucose (drives K+ intracellularly)
Salbutamol (drives K+ intracellularly) Calcium gluconate (cardio protective - but doesn't change serum K+) Dialysis Polystyrene sulphonate |
|
|
Rx mild acute asthma attack? (2)
|
Nebulised salbutamol
Oral pred or hydrocortisone (iv if oral not well tolerated) |
|
|
Rx severe asthma attack?
|
1) Nebulised (O2, Salbutamol, ipratropium bromide)+ Hydrocortisone or pred
if no improvement: 2) repeat 1 + MgSO4 if no improvement: 3) Consider aminophylline Magnesium sulphate |
|
|
Rx: acidosis
|
iv Fluid
and HCO3- (sodium bicarb) |
|
|
ECG changes in hyperkalaemia? (3)
|
flattening P wave
widening QRS complex prominent T-Waves |
|
|
Rx: TCA (e.g. amitriptyline, imipramine) overdose
|
Charcoal (1st hr only - gastric emptying)
Sodium bicarbonate (antidote) |
|
|

|
|
|
Complications of severe asthma attack? (1)
|
Pneumothorax (due to hyperinflation lungs)
|
|
|
Diagnosis?
Pa02 = 11kPa PaC02 = 2kPa pH = 7.28 HCO3- = 15 mmol/L |
Metabolic acidosis - [resp compensation]
low CO2 is compensating the low bicarb = hyperventilation |
|
|
Diagnosis?
Pa02 = 11kPa PaC02 = 8kPa pH = 7.53 HCO3- = 30 mmol/L |
Metabolic alkolosis
|
|
|
Diagnosis?
Pa02 = 9kPa PaC02 = 8kPa pH = 7.23 HCO3- = 21 mmol/L |
Respiratory Acidosis
|
|
|
Diagnosis?
Pa02 = 20kPa PaC02 = 2kPa pH = 7.53 HCO3- = 21 mmol/L |
Respiratory Alkalosis
