FALCON GUERRA, Miriam et al. Intravenous total anesthesia with remifentanil and fentanyl as analgesic base in elective thoracic surgery. Rev cuba anestesiol reanim [online]. 2020, vol.19, n.2, e561.  Epub 20-Maio-2020. ISSN 1726-6718.


Maintaining adequate oxygenation during single-lung ventilation is a fundamental concern faced by the anesthesiologist during thoracic surgery; therefore, a constant search is maintained for the ideal anesthetic method that helps achieve this goal is maintained.


To evaluate the outcomes of two total intravenous anesthesia techniques with remifentanil and fentanyl as analgesic base and to identify the onset of complications during surgery.


A prospective and quasi-experimental study was carried out at Dr. Salvador Allende Clinical-Surgical Hospital, between January 2013 and December, with 40 ASA II or III patients who required intrathoracic procedures. These were divided into two groups: A (remifentanil-propofol) and B (fentanyl-propofol). Hemodynamic variables and others of oxygenation during one-lung ventilation were studied, together with anesthetic recovery time (spontaneous ventilation, ocular opening, extubation) and postoperative analgesia.


There were no significant variations in the hemodynamics or oxygenation of patients with the use of both anesthetic techniques; however, awakening and short-term postoperative recovery was better in group A. Postoperative pain intensity, based on the analogue-visual scale, was lower in group B.


Both techniques are effective for thoracic surgical procedures, with minimal effect in hemodynamics and oxygenation parameters.
