Introduction:

Anesthesia for craniotomies is challenging due to the characteristics of the neurosurgical patient.

Objective:

To describe the perioperative behavior of patients operated on for supratentorial brain tumor with opioid-free anesthesia.

Methods:

A descriptive, longitudinal and retrospective study was conducted in 75 patients operated on for supratentorial brain tumor with the opioid-free anesthesia technique between January 2018 and December 2019 at Hospital Universitario General Calixto García. Hemodynamic (heart rate, as well as systolic, diastolic and mean blood pressure) and respiratory (respiratory rate, oxygen saturation and exhaled carbon dioxide) variables were analyzed, together with individual history and postoperative complications.

Results:

The average age was 54.2 ± 16.8, with a predominance of women, as well as of ASA II and hypertensive patients. The behavior of all the evaluated parameters was within the normal range. 96 % percent of the patients had no complications. Four complications occurred in three patients and none of them had important clinical repercussions.

Conclusions:

The opioid-free technique provided stability in hemodynamic and respiratory parameters, with few postoperative complications.
