ABSTRACT
[Objective]To summarize the clinical experience on anesthesia techniques for surgery of spinal tumors.[Method]A total of 546 patients undergoing surgery of spinal tumors were retrospectively studied,and the complications of surgery were also collected.[Result]There was no perioperative death.The average degree of blood loss was 1997ml per patient who usually required a large volume of blood transfusion.Acute pumonlary edema were occurred in 3 patients who were suspected to develop larynx edema immediately after operation.A perioperative visual loss following cervical spine surgery was also founded.[Conclusion]It is important to prevent and minimize blood loss by varied techniques during operation.Peventing adverse effect of operative position on patients and protecting their airway are also crucial for spinal surgery.
