Hemodynamic Changes Induced by Pneumoperitoneum and Measured With ECOM

Laparoscopic surgery presents unique hemodynamic challenges for the anesthetic management of patients. Hemodynamic changes induced by pneumoperitoneum were measured using a new noninvasive device, the Endotracheal Cardiac Output Monitor (ECOM) (ConMed Corp, Utica, NY). This monitor provides measurements—including cardiac output (CO), systemic vascular resistance (SVR), and stroke volume variation (SVV)—that were previously unavailable noninvasively. A better understanding of the applicability and reliability of this new technology in the clinical setting is important for patient safety. CONCLUSIONS
