PSA Flashcards
Resus fluids
500ml bolus over 15 mins
Reassess
Following fast bolus, adjust dose accordingly (250-500ml)
Replacement fluids needed in tachycardia and low BP
- tachycardia = usually 1-2L fluid depleted
- BP only starts going with more than 2L
maintenance fluid requirements
3 L over 24 hrs
1 salty, 2 sweet (1L normal saline, 2L 5% dextrose)
K+ (40-60mmol/24hrs)
K infusion rate and concentration
Rate <10 mmol/hr
Infusion concentration <40 mmol/L

interactions of paracetamol
- alcohol = hepatotoxic
- flucloxacillin = metabolic acidosis
- warfarin = inc INR
interactions of NSAIDs
- SSRIs/warfarin/DOAC/steroids = inc bleeding risk
- ACEi = hyperkalaemia
- Diuretics = AKIi
interactions of opioids
- alcohol = CNS depressant
- SSRI/ St John Wart/ Sumitriptan = serotonin syndrome
interactions of steroids
- aspirin = GI bleeding
- digoxin = dig toxicity
- erythromycin/citalopram = hypokalaemia
- antifungals = inc exposure of steroids
disulfram reactions
