Development and Internal Validation of a Preintubation Prediction Model for Postintubation Hypotension in Trauma Patients Undergoing Emergency Endotracheal Intubation: A Retrospective Cohort Study

Background/Objectives: Postintubation hypotension (PIH) is an important complication of emergency endotracheal intubation in trauma patients. However, the applicability of preintubation predictors of PIH in trauma patients undergoing emergency endotracheal intubation in the emergency department (ED) remains uncertain. Here, we aimed to develop and internally validate a preintubation prediction model for PIH in such patients.
