[Comparison of anesthetic maintenance and recovery with propofol versus sevoflurane combined with remifentanil in craniotomy for supratentorial neoplasm].
OBJECTIVE
To compare the effectiveness of propofol versus sevoflurane associated with remifentanil on the maintenance of anesthesia and on recovery in patients undergoing elective supratentorial craniotomy.


METHODS
Prospective randomized trial enrolling 90 patients scheduled for excision of a brain neoplasm. All received an infusion of remifentanil at a dose of 0.5 microg x Kg(-1) x min(-1) until tracheal intubation and then 0.25 microg x Kg(-1) x min(-1) during surgery. Induction was achieved with propofol and anesthesia was maintained with either sevoflurane at a maximum alveolar concentration of 0.4 (45 patients) or propofol by target controlled infusion at a concentration of 2.5 microg x mL(-1) (45 patients, group P). Variables assessed were hemodynamic stability during anesthesia and times and quality of recovery from anesthesia (eye opening, initiation of spontaneous ventilation, extubation, cough reflex, and temporal and spacial orientation 3 minutes after extubation. During the first 24 hours after surgery, pain intensity was evaluated on a verbal visual analog scale (VAS) and the incidence of nausea and vomiting was recorded.


RESULTS
Times until eye opening upon request and until extubation were significantly shorter in the sevoflurane group than in the propofol group: 3.7 (SD, 1.2) minutes vs 5 (3.1) minutes, respectively, for eye opening and 6.6 (1.2) minutes vs 8.1 (3.3) minutes for extubation (P<0.01). The incidence of nausea and vomiting was significantly higher in the sevoflurane group (40% vs 13%, respectively, P<0.01).


CONCLUSIONS
Combining remifentanil with propofol or with sevoflurane provides satisfactory anesthesia during elective supratentorial craniotomy to remove a brain neoplasm. Hemodynamic stability is appropriate and recovery from anesthesia is rapid.
