Although it has been possible to reduce the percentage of premature infants suffering intraventricular hemorrhage, posthemorrhagic hydrocephalus remains a serious problem without a good treatment. There is a high rate of cerebral palsy, and ventriculoperitoneal shunt surgery makes the child permanently dependent on the valve and catheter system. Shunt surgery ...
Whitelaw A - - 2001
Hydrocephalus following intraventricular hemorrhage (IVH) is still one of the most serious complications of premature birth. Ventriculoperitoneal shunt surgery cannot be carried out early and permanent dependence on a shunt is associated with several serious complications. To determine whether intraventricular streptokinase after intraventricular hemorrhage reduces the risk of permanent shunt ...

Intraventricular hemorrhage (IVH) is a major complication of preterm birth. Large hemorrhages are associated with a high risk of disability and hydrocephalus. Instability of blood pressure and cerebral blood flow are postulated as causative factors. Another mechanism may involve reperfusion damage from oxygen free radicals. Phenobarbitone has been suggested as ...
Whitelaw A - - 2001
Intraventricular hemorrhage remains a serious complication of premature birth and post hemorrhagic hydrocephalus still has no satisfactory treatment. Acetazolamide and furosemide, which both reduce the production of cerebrospinal fluid, have been suggested as non-invasive therapies to reduce hydrocephalus and the need for ventriculo-peritoneal (V-P) shunting. The aim of this review ...
