We wondered whether loading infusion of dexmedetomidine 1 μg/kg over 10 min to intracranial tumor patients was as efficient and safe as to those abdominal disease patients. Methods: Patients aged 18-60 years, male or female, ASA I or II, scheduled for intracranial tumor resection (Group N, n = 30) or abdominal operation (Group A, n = 30) were enrolled in this observational trial. Dexmedetomidine was administrated with a loading dosage of 1 μg/kg over 10 min following with continuous infusing of 0.5 μg/kg/h. Fentanyl, propofol and rocuronium were sequentially administered for anesthesia induction. Heart rate (HR), blood pressure (BP), pulse oxygen saturation (SpO2), bispectral index (BIS) and other adverse effects were recorded from the beginning of loading infusion of dexmedetomidine to the end of endotracheal intubation. Results: Among with loading infusion, HR and BIS value decreased and were significantly lower at the end of infusion than before infusion (P P > 0.05). One patient of Group N dropped out from this trial because of a serious headache. 14 of 29 patients during dexmedetomidine loading infusion suffered hypoxemia (SpO2 P Conclusion: A loading dosage of 1 μg/kg of dexmedetomidine was not suitable for the anesthesia induction of intracranial tumor patients as compared to patients undergoing abdominal operation.展开更多
