Massive transfusion of citrated blood leads to all except
Metabolic acidosis
Hypothermia
Hyponatremia
Hypocalcemia
Massive blood transfusion results in

Metabolic acidosis( lactate from RBCs, citric acid as anticoagulant)
Hyperkalemia( stored blood K+ reaches 30mmol/L after 3 weeks)
Hypothermia (as stored blood is kept at 4°C)
Decreased ionized calcium( due to citrate binding to calcium).
