The cost of a dose of succinylcholine from society's perspective equals the
acquisition cost of the drug plus the cost of its adverse outcomes. We hyp
othesized that although the acquisition cost of succinylcholine is minimal,
the true cost would be much larger. We reviewed the medical literature to
identify the total cost of a dose of succinylcholine when administered for
nonemergency purposes according to manufacturers' guidelines (i.e., to adul
ts only). We found that 88% of the cost per dose of succinylcholine was for
the chance of dying or sustaining permanent brain injury from anaphylactic
or anaphylactoid reactions to succinylcholine. Consequently, the estimated
cost per dose of succinylcholine was sensitive to the incidence of anaphyl
actic or anaphylactoid reactions to succinylcholine, the risk of severe inj
ury from anaphylactic or anaphylactoid reactions, and the financial value o
f unforeseen instant death or permanent brain injury. The range for the cos
t per dose of succinylcholine was thus large, $9 to $93. Our best estimate
of the cost per dose was $37. We conclude that the true cost per dose of su
ccinylcholine from society's perspective is more than 20 times the acquisit
ion cost. However, a precise costing requires better knowledge of the incid
ence and consequences of anaphylactic or anaphylactoid reactions to succiny
lcholine.
