Abstract:
Objective To investigate the clinical application of remifentanil in awake state for removal of tumors in functional brain area. Methods Twenty-four patients with tumors in functional brain area were divided into two groups by random digits table with 12 cases each:control group and remifentanil group. Infiltration anesthesia was used in all patients with 0.2% ropivacaine. Remifentanil was injected intravenously with micropump in 0.05-0.10 μg/ (kg·min) in remifentanil group and 0.9% sodium chloride was instead of remifentanil in control group. Patients remained awake during surgery in both groups. The hemodynamic changes and complications during operation were monitored. The satisfaction for surgical procedure was evaluated. Results The patients in two groups could be completed in awake state with surgery;mean artery pressure, heart rate in remifentanil group during opening or closing skull or intracranial period were significantly higher than those in control group(P< 0.05). There were no conspicuous complication in two groups such as respiratory depression, nausea, vomitting and dysphoria. The satisfaction score in remifentanil group[(3.3 ?0.6) scores] was higher than that in control group[(2.4 ?0.5) scores],there was significant difference between two groups (P<0.05). Conclusion Awake brain tumor surgery could be completed in rational use of remifentanil on the base of good local anesthesia, and hemodynamics are stable and the patients are well tolerated.
