Sixty ASA Ⅰ-Ⅱ patients undergoing TURBT were randomly assigned to 2 groups. Spinal anesthesia with 0. 75% pure bupivacaine （8-12 rag） was applied to patients in Group Ⅰ （n= 30）. Patients in Group Ⅱ （n=30） received total intravenous anesthesia with continuous infusion of Propofol and Remifentanil ; and a laryngeal mask was used to ensure the airway and ventilation. BP, HR, SPO2 and pertinent side effects were monitored and recorded. Results ： The patients in group Ⅱ experienced more stable hemodynamics than those in group Ⅰ . Obturator nerve reflex was observed in 15 （50. 0%） patients in Group Ⅰ , but none （0%） in Group Ⅱ （P〈0. 01）. Conclusion.. Total intravenous anesthesia with laryngeal mask is a safe, reliable, controllable and simple manual for patient undergoing TURBT.展开更多

The LMA was removed until the patient awakened.The anesthesiologist then kept up an on-going neuro- logical examination.After that,anesthesia was re-deepened and LMA was re-inserted until the whole surgery was accomplished.Results:Forty-six of 50 patients(92%)were successfully awakened and 4 (8%)failed to complete the intraoperative wake-up test because of dyspnea,over-sedation,or severe hy pertension.No severe complications occurred during the whole process.Conclusions:During the awake anesthetic period,the intraoperative wake-up test combined with navigation,evoked potential and ultra- sound techniques can help surgeons excise maximumly and precisely the brain tumors near to or in the functional areas.展开更多
