Abstract:
Objective To describe the survival state and to investigate the risk factors of death on patients with subarachnoid hemorrhage (SAH). Methods Age, past history, number of encephalic region suffering SAH, laboratory examination indexes, therapeutic measures, complications and prognosis of 174 patients with SAH were followed-up and investigated. The survival states and risk factors of death of the patients with SAH were identified by both Kaplan-Meicr survival analysis and Cox proportional risk model. Results There were 10 patients (5.75%) losing follow-up investigation and 164 patients with SAH completed the follow-up investigation. 66 patients died and the longest follow-up invcstigation time was 5.64 years. The survival rates of 28 days, 1 year and 3-5 years were 70.60%,63.40% and 57.20% respectively. The treatment of nimotop, aneurysm occlusion treatment and aneurysm embolotherapy could decrease the death of SAH. At the same time, advanced age, the long time smoking, hyponatremia, the rising of leucocyte in acute stage, repeated hemorrhage and cerebral angio spasm were the independent risk factors to the death of patients. Conclusion Prognosis of patients with advanced age, the rising of leucocyte in acute stage, gastrointestinal blooding, hyponatremia, repeated hemorrhage and cerebral angio spasm were unfavorable. When giving patients with aneurysm, the aneurysm occlusion and embolotherapy and nimotop treatment, the death risk could be reduced.
