So before anyone gets too crazy about this, let me make a point. The intubating dose is still 1-2 mg/kg. However, more recent studies have shown that the LARYNGOSPASM dosage is as low as 0.1 mg/kg IV. This provides many benefits such as shorter (if any) apnea time, less need for additional sedation or mechanical ventilation. The authors suggest that the lower dosage may not cause apnea but will relieve laryngospasm due to the sensitivity of the larynx to succinylcholine.<ref>Chung, D. C., and S. J. Rowbottom.

The answer is A.
So before anyone gets too crazy about this, let me make a point. The intubating dose is still 1-2 mg/kg. However, more recent studies have shown that the LARYNGOSPASM dosage is as low as 0.1 mg/kg IV. This provides many benefits such as shorter (if any) apnea time, less need for additional sedation or mechanical ventilation. The authors suggest that the lower dosage may not cause apnea but will relieve laryngospasm due to the sensitivity of the larynx to succinylcholine.[1]
