Resumo(s)
Portugal apresenta uma das mais altas taxas de prematuridade do continente euro-
peu. A prematuridade pode acarretar uma série de desafios como alterações físicas e
emocionais, bem como nas dinâmicas familiares. Os avanços na medicina e nos cuidados
perinatais têm permitido o aumento das taxas de sobrevivência de bebés prematuros.
No entanto, estes continuam a apresentar um maior risco de mortalidade que os bebés
nascidos a termo, bem como de sofrerem problemas de saúde e de desenvolvimento. A
implementação de terapias de intervenção, prevenção e acompanhamento destas crianças
deve ser tido em conta, nomeadamente ao nível das suas competências visuomotoras.
Na presente dissertação, recolheu-se e foi feita a posterior análise de potenciais evoca-
dos visuais (técnica que avalia a resposta cerebral desencadeada por estimulação visual)
aplicados a bebés nascidos prematuramente de forma longitudinal (aos 4 e 6 meses de
idade corrigida), o que pretende ser um método de avaliação objetivo do desenvolvi-
mento das crianças em termos de registos encefalográficos. Sabendo que uma avaliação
atempada através do estudo das competências visuomotoras em bebés prematuros revela
precocemente alguma imaturidade que as crianças possam vir a apresentar durante o
seu desenvolvimento, as conclusões retiradas de todo o processo têm como objetivo a
elaboração de um plano de intervenção mais adequado.
Como resultado do estudo desenvolvido, concluiu-se que se verificou a tendência de
que quanto menor a idade gestacional, maior a latência de P100. Esta tendência mostrou-
se mais relevante para os 6 meses de idade corrigida. Portanto, demonstra-se que a idade
gestacional deve ser tida em conta no acompanhamento e nas terapias de estimulação do
desenvolvimento visuomotor.
Portugal has one of the highest rates of prematurity on the European continent. Prema- turity can cause a series of challenges such as physical and emotional changes, as well as in family dynamics. Advances in medicine and perinatal care have allowed the survival rates of premature babies to increase. However, they continue to have a higher risk of mortality than full-term babies, as well as suffering from health and developmental prob- lems. The implementation of intervention, prevention and monitoring therapies for these children must be taken into account, particularly in terms of their visuomotor skills. In the present dissertation, it was collected and performed a posterior analysis of vi- sual evoked potentials (a technique that evaluates the brain response triggered by visual stimulation) applied to babies born prematurely in a longitudinal way (at 4 and 6 months of corrected age), which intends to be an objective evaluation method of children’s de- velopment in terms of of encephalographic records. Knowing that a timely assessment through the study of visual-motor skills in premature babies early reveals any immatu- rity that children may present during their development, the conclusions drawn from the whole process aim to develop a more appropriate intervention plan. As a result of the developed study, it was concluded that there was a tendency that the lower the gestational age, the greater the P100 latency. This trend was more relevant for 6 months of corrected age. Therefore, it is demonstrated that the gestational age should be taken into account in the follow-up and in the therapies to stimulate the visuomotor development.
