title: [Monitoring of fontanelle pressure in neonates and infants. Evaluation of a new measuring technique, determination of normal values and clinical usefulness].
abstract: The experience with 200 measurements of anterior fontanelle pressure with the Rotterdam Teletransducer in newborns and infants is reported. Statistical analysis of 25 comparative measurements between anterior fontanelle pressure and invasive cerebrospinal fluid pressure showed an excellent correlation (rs = 0.95). Measurements were reproducible and the plot quality allowed visualisation of pulse pressure and pressure waves. Normal values of the anterior fontanelle pressure, pulse pressure amplitude and pressure wave maximal amplitude were established in 15 prematures, 27 term newborns and 10 infants. Anterior fontanelle pressure monitoring was performed in 19 term newborns with post-asphyxial encephalopathy, 18 newborns and infants with hydrocephalus, 8 preterm and term newborns with respiratory distress and 19 patients with subdural haematomas, metabolic diseases, meningitis, subarachnoidal haemorrhage, head trauma, post cardiac arrest encephalopathy and abnormal head growth or bulging fontanelle. Abnormal patterns of anterior fontanelle pressure monitoring were found in moderate or severe neonatal post-asphyxial encephalopathy, evolutive hydrocephalus, subdural haematomas, metabolic diseases with hyperammoniemia and other clinical situations. In contrast, anterior fontanelle pressure monitoring yielded normal values in mild post-asphyxial encephalopathy, arrested hydrocephalus, well functioning ventriculo-peritoneal derivation, and in normal infants with rapid head growth or bulging fontanelle. The Rotterdam Teletransducer provides thus accurate and reproducible values of intracranial pressure. Anterior fontanelle pressure monitoring may be of value in many situations in clinical practice.
