Q

if urine is dark after burn

A

assume electrical burn and affected the muscle and pt is in rhabdomyolysis releasing myoglobin.
increase fluid to achieve a urine output of 100ml/hr
if urine doesn’t clear up then use mannitol to continue diuresis
Control metabolic acidosis by perfusion and add sodium bicarbonate as needed to alkalinize urine to solubilize myoglobin

Q

tx of hemorrhagic shock

A
give 1-2 L bolus to adults
give 20mL/kg to kids
monitor by
urine output 30-50 ml/hr
urine output for kids 1ml/kg/hr (for kids younger then 1 yrs is 2mL/kg/hr)
