Remifentanil versus fentanyl in total intravenous anesthesia for lumbar spine surgery: a retrospective cohort study

• We compare the speed of anesthetic recovery and the perioperative analgesic requirements in patients who received total intravenous anesthesia (TIVA) with either remifentanil-propofol or fentanyl-propofol for lumbar spine surgery.
• Speed of emergence from anesthesia and length of stay in the post-anesthesia care are identical.
• Postoperative pain control is superior with the use of fentanyl.
• We recommend the use of fentanyl-propofol TIVA for lumbar spine surgery.

Study objectiveThe aim of this study was to compare the speed of anesthetic recovery and the perioperative analgesic requirements in patients who received total intravenous anesthesia (TIVA) with either remifentanil-propofol or fentanyl-propofol for lumbar spine surgery.DesignRetrospective cohort study.SettingOperating room, postanesthesia care unit, and general surgical ward.PatientsOne hundred six patients (53 in each group) with American Society of Anesthesiologists status I, II, or III who received either remifentanil-propofol TIVA or fentanyl-propofol TIVA for elective lumbar vertebral disc surgery.MeasurementsPatient demographics, total duration of anesthesia relative to surgical duration, time to emergence from anesthesia after completion of surgery, length of stay in the postanesthesia care unit, and requirements for opioid analgesia, nonopioid analgesia, and antiemetics in the perioperative period.Main resultsNo differences in anesthesia time, emergence time, or length of stay in the postanesthesia care unit were found between the remifentanil-propofol and fentanyl-propofol groups. Postoperative opioid and nonopioid analgesic use was significantly higher in the remifentanil-propofol group.ConclusionsRemifentanil and fentanyl are equally efficient with regard to the speed of patient turnover when used as part of TIVA for lumbar disc surgery, but remifentanil use is associated with increased perioperative analgesic requirements.
