ELECTROLYTES
Ca disorders
acute hypoCa
causes
parathyroidectomy
pancreatitis
sepsis
tumor lysis syndrome
acute alkalosis
chelation
EDTA
blood transfusion
foscarnet
presentation
muscle cramps
Chovstek and Trouseau
paresthesias
hyperreflexia/tetany
seizures
treatment
IV Ca gluconate/chloride
pathophysiology
Na citrate and citric acid used to preserve RBCs
massive transfusion - don't have enough time to clear it
underlying disorder (liver, kidneys, sepsis) cannot clear it effectively
Citrate binds to ionized (free) Ca
Dx
measure ionized Ca level
serum Ca may be normal
hypoCa
causes
surgery (during or immediately after)
extensive transfusions
K disorders
hyperkalemia
a/w
crush injuries
renal insufficiency
severe burns
presentation
ECG changes
asystole
GI disturbances (N/V)
Mg Disorders
hypoMg
may mimic hypoCa
a/w
prolonged NT suction
diarrhea
heavy EtOH use
diuretic use
hyperMg
presentation
dec DTR
loss of DTR
muslce paralysis
flaccid quadriplegia
dec respiration
apnea
Na disorders
