Objective
To investigate the curative effect of Ommaya reservoir drainage on reducing intracranial pressure in children with hydrocephalus.
Methods
From January 2015 to June 2016,50 children underwent Ommaya capsule implantation in Department of Neurosurgery,Hunan Children's Hospital,and they were enrolled in this study. Before the treatment,children and their families were mentally guided. After treatment observe the changes of the patient's condition,check the drainage status of the Ommaya sac draining device,and regularly check the intracranial pressure in children and other physiological indexes. After the treatment incision care and regular examination of children's body temperature,cerebrospinal fluid color and blood was performed. Low intracranial pressure due to excessive drainage should be prevented.
Results
Complications after Ommaya capsule implantation happened in 11 cases,including 3 cases of secondary intracranial infection,2 cases of drainage tube obstruction,1 case of secondary intraventricular hemorrhage and 1 case of rejection. Low intracranial pressure caused by excessive drainage occurred in 4 cases,while the remained children were with intracranial pressure reducing to normal levels,the complication rate being 22.0%. After targeted treatment,the symptoms of complications were effectively improved,and there was no recurrence.

Conclusion
Ommaya capsule implantation for children with hydrocephalus can reduce intracranial pressure,and the rate of complications is low,which is worthy of clinical use.
