    Pulse Contour Analysis and Transesophageal Echocardiography: A Comparison of Measurements of Cardiac Output During Laparoscopic Colon Surgery
    (LIPPINCOTT WILLIAMS & WILKINS, 2009) Concha, Mario R.; Mertz, Veronica F.; Cortinez, Luis I.; Gonzalez, Katya A.; Butte, Jean M.
    BACKGROUND: Pulse wave analysis (PWA) allows cardiac output (CO) measurement after calibration by transpulmonary thermodilution. A PWA system that does not require previous calibration, the FloTrac/Vigileo (FTV), has been recently developed. We compared determinations of CO made with the FTV to simultaneous measurements using transesophageal echocardiography (TEE).

    The Volume of Lactated Ringer's Solution Required to Maintain Preload and Cardiac Index During Open and Laparoscopic Surgery
    (LIPPINCOTT WILLIAMS & WILKINS, 2009) Concha, Mario R.; Mertz, Veronica F.; Cortinez, Luis I.; Gonzalez, Katya A.; Butte, Jean M.; Lopez, Francisco; Pinedo, George; Zuniga, Alvaro
    BACKGROUND: Recent studies have emphasized the importance of perioperative fluid restriction. However, fluid restriction regimens may increase the likelihood of insufficient perioperative fluid administration or may result in excess intravascular crystalloid replacement. We postulate that the use of transesophageal echocardiography may reduce the amount of crystalloid administered during open and laparoscopic colorectal surgery.
