Non-invasive measurement of the intracranial pressure (ICP) via the anterior fontanelle by using an applanation transducer has been performed. Recently, a new fontanometer using an applanation transducer has been developed in our department by improving the conventional Statham transducer, P-50 which is currently accepted for its high reliability. In this study, by analysing patterns of the ICP pulse waves obtained from this new fontanometer, its clinical evaluation has been made in 27 neonates and infants in intracranial pathologies. Analysing the ICP waveforms, the first peak (P1) was divided by the following second peak (P2) and the changes in P1/P2 were examined. A differential amplifier, a dP/dt detector, was also used to make it easier to identify the turning point on the pulse waves. The results obtained demonstrated that the waveforms of ICP in neonates as well as infants are influenced by not only the intracranial constituents but compliance of the container such as the scalp, cranium and the meninges.
已通过使用压平式换能器经前囟门进行颅内压（ICP）的无创测量。最近，我们科室通过改进传统的斯塔瑟姆换能器P - 50（目前因其高可靠性而被认可）开发了一种新的使用压平式换能器的囟门测压仪。在本研究中，通过分析从这种新的囟门测压仪获得的ICP脉搏波模式，对27例患有颅内病变的新生儿和婴儿进行了临床评估。分析ICP波形时，将第一个峰值（P1）除以下一个峰值（P2），并检查P1/P2的变化。还使用了一个差分放大器，即dP/dt检测器，以便更轻松地识别脉搏波上的转折点。获得的结果表明，新生儿和婴儿的ICP波形不仅受颅内成分的影响，还受头皮、颅骨和脑膜等容器顺应性的影响。
