Abstract: ObjectiveTo explore the mechanism and prevention for the hypertension complicated by the retroperinoneal paraganglioma operation.MethodsBlood pressures were monitored during operations on 15 patients with retroperinoneal paraganglioma. Also,the reason and the prevention for the changed blood pressure were studied emphatically during operation.ResultsThe elevated blood pressure of 12 patients was detected during operation,and all dropped to a varied degree after operation,with 2 of them below the normal value.ConclusionThe retroperinoneal paraganglioma operation was liable to cause blood pressure elevated,which was related to the anesthesia induction and the operation stimulation of tumor. After the excision of the tumor,blood pressure of most of the patients dropped to some degree. Therefore,during the retroperinoneal paraganglioma operation,the blood pressure should be monitored closely,and the short-acting antihypertensives should be applied on time. Meantime,occurrence of hypotension was also considered after the excision of the tumor.
