labs:

PH 7.24

Pco2 29

HCO3 12

Na 140

K4.5

Cl 102

Most appropriate treatment?

a.give HCO3 IV bolus

b.oral HCO3

c.HCO3 IV drip

its acidosis probably gue to muscle break down myogloginemia and myoglobinuria. if im on the rigth track lets give him a.give HCO3 IV bolus to alkalinize his urine



  #5

metabolic acidosis with respiratory compensation, give iv bolus of bicarb

Wait and repeat labs... I dont think rhabdomyolisis produces a rapid onset of acidosis... It is a consequence of an increased lactic acid production, since there is an increased motor activity and a decreased alveolar ventilation, with lots of anaerobic glycolisis and you know the results...

well yes mazinger is right.It is lactic acid.I have learned that in qs like these,always calculate anion gap.here it is

140-102+12=140-112=28

so it is anion met acidosis,in this case due to rhabdomyolysis lactic acidosis.UW says this lactic acidosis after a seizure resolves on its own in 72 hrs so we will observe,
