Bispectral Index and First-Pass Intubation

This prospective observational study aims to evaluate the association between anesthetic depth, measured by the Bispectral Index (BIS), and first-pass endotracheal intubation success in adult patients undergoing rapid sequence intubation (RSI) in the emergency department. Endotracheal intubation is one of the most critical procedures performed in emergency medicine. Multiple intubation attempts are associated with an increased risk of adverse events, including hypoxemia, aspiration, cardiovascular complications, and death. Although several factors influence first-pass intubation success, the contribution of anesthetic depth at the time of intubation has not been adequately investigated in the emergency department. Patients for whom the treating emergency physician decides to perform RSI will undergo noninvasive BIS monitoring using a disposable forehead sensor. The physician performing
