case continues:
  • Glycopylorate, 50 micrograms, IV, was titrated without change in heart rate.
  • The patient was preoxygenated for one minute before proceeding with a rapid induction sequence using ketamine, 1 mg/kg and succinylcholine, 1mg/kg.
  • The trachea in intubated with ease using a 4.0 mm endotrachial tube.

Thiopental and propofol are common induction agents. Ethomidate would be another possibility. However, they were not used. Suggest possible reasons why.
