MSFinals-6403

A 65-year-old man comes to the Emergency Department with severe abdominal pain and haematemesis. Following initial resuscitation, an urgent CT scan shows a perforated duodenal ulcer. The surgical team schedules an emergency laparotomy, and he is transferred to the operating room. Due to his non-fasted state, the anaesthetist intends to perform a rapid sequence induction (RSI) using a depolarising muscle relaxant to minimize airway obstruction.
What is the appropriate drug to use in this situation?
