Comparison of muscle paralysis after intravenous and intraosseous administration of succinylcholine in Swine.

Aim: To compare the onset and duration of intravenous (IV) and intraosseous (IO) administration of succinylcholine in swine.

Methods: Electromyographic (EMG) amplitudes were used to characterize muscle paralysis following administration of succinylcholine via the IV or IO route in four Yorkshire-cross swine.

Results: The onset of action of succinylcholine was statistically longer after IO administration (0.
