Serial lumbar punctures for the management of neonatal posthemorrhagic hydrocephalus without intracranial hypertension were evaluated in 16 infants. Cranial ultrasonography to evaluate ventricular size and the Ladd monitor at the anterior fontanel to measure intracranial pressure were utilized immediately before and after lumbar puncture. In 12 patients, a decrease in ventricular size and in anterior fontanel pressure could be effected with each lumbar puncture. In these infants, cessation of progression of the hydrocephalus and intermittent decreases in ventricular size were accomplished. In four patients, lumbar punctures were not successful in decreasing ventricular size or lowering intracranial pressure. Two criteria could be defined to determine whether lumbar puncture could provide at least temporary benefit for the treatment of posthemorrhagic hydrocephalus. The first of these is to establish the presence of communication between lateral ventricles and lumbar subarachnoid space by effecting a decrease in ventricular size and a decrease in intracranial pressure by removal of CSF. The second criterion is to ascertain a critical volume of CSF (usually relatively large) that must be removed in order to effect the above changes. Cranial ultrasonography and measurement of intracranial pressure by application of the Ladd monitor to the anterior fontanel are extremely valuable in the evaluation of lumbar punctures in the management of posthemorrhagic hydrocephalus.

Hyperglycorrachia was produced in anesthetized dogs by the administration of intravenous glucose. The glucose entered the lumbar subarachnoid space more rapidly than it entered the cisternal subarachnoid space. This finding is a reverse of the diffusion into the cisternal and lumbar regions in man after the administration of intravenous glucose. The pattern in dogs is different from that in man under normal circumstances, but follows the pattern present when radioactive sodium 24 is used as a diffusible substance. It is concluded that glucose diffuses directly into the spinal subarachnoid at a rapid rate in the dog. This may be due to anatomical differences in various species.
