Rapid sequence induction
Rapid Sequence Induction (pronounced: RAP-id SEE-kwens in-DUK-shun) is a medical procedure often used in Emergency Medicine and Anesthesiology. It is a method of anesthetizing a patient quickly, while minimizing the risk of aspiration.
Etymology
The term "Rapid Sequence Induction" is derived from the speed at which the procedure is performed (rapid), the order in which the steps are carried out (sequence), and the initiation of the procedure (induction).
Procedure
Rapid Sequence Induction, or RSI, involves several steps. First, the patient is preoxygenated to increase the amount of oxygen in their lungs. This is followed by the administration of a potent, fast-acting anesthetic drug and a neuromuscular blocking drug. The patient is then intubated with an endotracheal tube to secure the airway. The entire process is performed as quickly as possible to minimize the risk of aspiration.
