Critical Care Flashcards
sodium requirements
1-2mmol/kg/day
potassium requirements
0.5-1mmol/kg/day
Fluid requirements
25-30ml/kg/day
Glucose requirements
50-100g/day
What is the most sensitive indicator of severe illness
Abnormal respiratory rate
Who often requires ventilatory support
Severe pneumonia CAP/HAP PE CCF Life threatening bronchospasm SIRS
Fluid challenge -
Give the patient volume of fluid and see whether the HR and BP changes
State the normal limit on fluid resuscitation
30ml/kg
State the MAP that should be aimed for
65mmHg
Inotropes
Increase the contractiitu of the heart (B1 agonists)
Vassopressors
Cause venous constriction
Crystalloid
Small molecules, 0.9% saline, 5% dextrose, Hartmanns solution
Colloid
Large molecules, common blood (if bleeding) and albumin
Normal Urine output
0.5ml/kg/hour
Renal support
Continuous veno-venous haemofiltration
How can the brain be supported
Management of physiological parameters, PCO2, PO2, MAP, Glc, Temp
Osmotherapy, mannitol, hypertonic saline
Therapeutic hypothermia
Burst suppression of cerebral activity
How can the cardiovascular system be supported in critical care
Invasive monitoring with appropriate fluid resuscitation
Inotropic or vasoactive support
Intra-aortic balloon counterpulsation
Extracorporeal support e.g. AV ECMO, VAD
