Abstract Funding Acknowledgements Type of funding sources: None. Background A new mathematical model allows calculation hemodynamic forces (HDF) from routine transthoracic echocardiographic images. In large cohorts, the evolution HDF parameters in patients after onset cardiac resynchronization therapy (CRT) has not been investigated. Purpose To compare at baseline versus six months follow-up CR...

OBJECTIVE General anesthesia causes reduction of functional residual capacity. And this decrease can lead to atelectasis and intrapulmonary shunting in the lung. In this study we want to evaluate the effects of 5 and 10cmH2O PEEP levels on gas exchange, hemodynamic, respiratory mechanics and systemic stress response in laparoscopic cholecystectomy. METHODS American Society of Anesthesiologist...

Introduction: One of the most common problems during laryngoscopy involves sympathetic system stimulation and the subsequent hemodynamic changes. It is a key measure to maintain the hemodynamic stability of patients with cardiovascular diseases during induction of anesthesia. This study attempted to compare the hemodynamic effects of laryngeal mask airway and combitube. Methods: This prospec...
