Objective      To analyze the associated risk factors for complications in spontaneous cerebral hemorrhage patients.       Methods      Clinical data about 443 spontaneous cerebral hemorrhage patients were retrospectively analyzed and the possible risk factors for complications of spontaneous cerebral hemorrhage were analyzed by logistic regression analysis.       Results      Binary logistic regression analysis showed that history of diabetes mellitus (DM) and cerebral hemorrhage into ventricles were the associated risk factors for pulmonary infection (OR=4.449

P0.01; OR=2.227

P0.05) while level of consciousness and history of DM were the associated risk factors for respiratory failure (OR= 2.715

P0.01; OR=11.071

P0.05) and abnormal lipid metabolism was the associated risk factor for electrolyte disturbance (OR=14.832

P0.05) in spontaneous cerebral hemorrhage patients.       Conclusion      Spontaneous cerebral hemorrhage patients accompanying history of DM at admission and cerebral hemorrhage in ventricles after admission are easy to occur pulmonary infection. Those with abnormal lipid metabolism or disturbance of consciousness and history of DM are easy to have electrolyte disturbance or respiratory failure.
