Abstract
A hydrocephalic child, who was operated with a ventriculo-peritoneal shunt at the age of 1 month, developed ventriculitis due to Pseudomonas aeruginosa at 8 months. After removal of the shunt and successively increasing intramuscular and intraventricular doses of gentamicin the patient was cured and a new shunt could be inserted. As high 24-hour gentamicin level in the cerebrospinal fluid as 76 μg/ml was reached without any apparent toxic signs.
