Abstract: Objective: To investigate the clinical value of continuous lavage drainage of lateral ventricle in the treatment of intraventricular hemorrhage.Methods: Forty-six patients with intraventricular hemorrhage were randomly divided into the treatment group and control group.The treatment group and control group were treated with double lateral drainage combined with continuous urokinase lavage and urokinase injection,respectively.The clinical effects between two groups were compared.Results: The effective rate,time of clearing intraventricular hemorrhage,intracranial infection rate and hospitalization time in treatment group were better than those in control group(P<0.05 to P<0.01).Conclusions: Lateral ventricle lavage is an effective method in treating intraventricular hemorrhage.
