RESUMEN
Information about the morphology of the intracranial pressure waveform, as well as the variations in intracranial pressure (ICP) and compliance in pediatric patients are essential to diagnose and predict the progression of various neurological conditions. However, there is no information on the morphology of the IP waveform in neurologically healthy pediatric patients. In the present study, intracranial compliance was therefore analyzed in neurologically healthy patients with the aid of a noninvasive device. The study was an observational, cross-sectional study. Fifty-five neurologically healthy participants were included. Data on intracranial compliance with the patient in two positions, lying down (0°) and seated (45°), were collected with a noninvasive extracranial sensor, which allowed the intracranial pressure waveforms to be recorded. The values of the ratio P2/P1 were then analyzed. A questionnaire (with a scale from zero to ten, where ten corresponds to the highest level of satisfaction) was applied for patients to evaluate their satisfaction with the sensor. Patients were 10 years old (average), and most of them were (58%). Mean P2/P1 ratio was 0.94 (sd = 0.14) in the supine position and 0.91 (sd = 0.15) in the seated position. Participants were satisfied with the length of time for which the equipment was used (9.8, sd = 0.71). The device did not cause any discomfort. The noninvasive method used was well accepted by the patients. Intracranial compliance values were determined by analysis of the P2/P1 ratio in neurologically healthy pediatric population.Trial registration: Brazilian Registry of Clinical Trials Identifier: RBR-5j74ddg.

ABSTRACT Professor Sérgio Mascarenhas was a Brazilian researcher with a vast legacy. His work paved the way for new research possibilities by consolidating the use of innovation and transdisciplinary science. In Medicine, he proposed changes to what had previously been well-accepted concepts, and his contributions have influenced medical practices. Although many authors consider intracranial pressure (ICP) as an unrivaled variable for monitoring and diagnosis of many diseases, its clinical applicability is still the subject of debate in the literature because of the difficulty in standardizing protocols. Mascarenhas's research and the creation of a device for noninvasive monitoring of intracranial compliance are discussed and are shown to have led to the creation of Brain4care, a start-up, and a new perspective on the debate on ICP monitoring.
RESUMO O professor Sérgio Mascarenhas foi um pesquisador com vasto legado. Seu trabalho abriu caminho para novas possibilidades de pesquisa, consolidando o uso da inovação e da ciência transdisciplinar. Na Medicina, ele propôs mudanças no que antes eram conceitos bem-aceitos, e suas contribuições influenciaram a prática médica. Embora muitos autores considerem a pressão intracraniana (PIC) uma variável incomparável para o monitoramento e o diagnóstico de uma série de doenças, sua aplicabilidade clínica ainda é motivo de debate na literatura pela dificuldade de padronização de protocolos. A pesquisa do Professor Mascarenhas e a criação de um dispositivo para o monitoramento não invasivo da complacência intracraniana levaram à criação do Brain4care, uma start-up, e a uma nova perspectiva sobre o debate do monitoramento da PIC.
