The Impact of Propofol and Ketamine on Cardiovascular Collapse During Induction for Intubation

Abstract

This prospective observational study evaluates the impact of propofol and ketamine on the risk of cardiovascular collapse during induction for endotracheal intubation in critically ill patients. Induction agents play a crucial role in managing hemodynamic stability, particularly in this vulnerable population. Propofol, known for its vasodilatory and myocardial depressant effects, has been associated with significant hypotension during induction. Conversely, ketamine, with its sympathomimetic properties, is often considered a safer alternative for hemodynamic stability. In addition to comparing the incidence of cardiovascular collapse-defined as severe hypotension or cardiac arrest-this study examines the relationship between these induction agents and shock indices, including systolic shock index, diastolic shock index, age-adjusted shock index, and modified shock index. These parameters will provide a more detailed understanding of the hemodynamic effects of each agent and their clinical implications. The findings aim to guide induction agent selection to optimize outcomes in critically ill patients.
