The Impact of Propofol and Ketamine on Cardiovascular Collapse During Induction for Intubation
Sponsor: Kocaeli City Hospital
Summary
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.

propofol
The hemodynamic effects of propofol and ketamine are well-documented in the general patient population, yet the incidence and characteristics of cardiovascular collapse induced by these agents in critically ill patients remain underexplored. Cardiovascular collapse, a severe and potentially life-threatening event, may arise due to the unique physiological stressors present in the critical care setting, including pre-existing hemodynamic instability, comorbidities, and the administration of high-risk pharmacological agents. Despite the theoretical understanding of these drugs' pharmacodynamics, there is limited evidence assessing their differential impact on cardiovascular function in this vulnerable population. This study aims to contribute novel insights to the literature by exploring the association between these widely used sedative-hypnotic agents and the development of cardiovascular collapse. While propofol is known for its potent vasodilatory and myocardial depressive effects,
