Rapid Sequence Induction
Modified anesthesia induction technique that minimizes the time between loss of consciousness and securing the airway to reduce aspiration risk.
Full Definition
Rapid sequence induction (RSI) is a specialized anesthesia induction technique designed to quickly secure the airway while minimizing the risk of pulmonary aspiration of gastric contents. In obstetric anesthesia, RSI is the standard approach for general anesthesia due to the increased aspiration risk associated with pregnancy-related physiological changes including delayed gastric emptying and increased gastric acid production. The technique involves pre-oxygenation, rapid administration of induction agents and neuromuscular blocking drugs, followed by immediate endotracheal intubation without positive pressure ventilation. Cricoid pressure may be applied to further reduce aspiration risk until the airway is secured.
Usage
Usage note: Standard technique for obstetric general anesthesia.
