Q

26 yo F with v-tach, metabolic acidosis, muscle rigidity, 102˚F; this type o reaction to the medication runs in her family

A

malignant hyperthermia

  • occurs as a result of administration of NMJ blockers (succinylcholine, halathone)
  • results in hyperthermia, muscle rigidity, arrhythmias, hypotension, rhabdomyolysis, and DIC
  • hypersensitivity to these kinds of Rx runs in families

Q

22 yo M presents with extreme rigidity, ∆ mental status, 104˚F, and highly elevated CPK

A

NMS

  • due to neuroleptic use
  • ∆ in mental status, autonomic instability (hyperthermia, tachycardia, labile HTN, tachypnea), and lead pipe muscle rigidity
