A New Instrument for Non-invasive Measurement of Intracranial Pressure via the Anterior Fontanelle

Intracranial pressure (ICP) is one of the most important parameters in evaluating intracranial pathology. The skulls of the newborn and the infant, unlike the tightly sutured skull of the adult, provide non-invasive access to ICP via the anterior fontanelle. The authors have developed a new transducer which is convenient for non-invasive, continuous measurement of the intracranial pressure through the anterior fontanelle. The new transducer is thinner and lighter than the APT-16 type transducer (Hewlett-Packard). The authors described the principles of measurement with this new transducer via the anterior fontanelle, the results of basic experiments, and some clinical results obtained through its numerous clinical applications.
