Revisitando o perímetro craniano de recém nascidos brasileiros de maternidades públicas e privadas

Autoria SCIMAGO INSTITUTIONS RANKINGS

RESUMO

Objetivo

Revisitar o perímetro cefálico (PC) de recém nascidos (RN) correlacionando com a idade gestacional (IG), gênero, tipo de parto (TP), sistema de saúde e construir e validar gráficos e curvas.

Métodos

Estudou-se prospectivamente RN sadios analisando-se as diferenças entre os PC segundo a IG, gênero, TP e sistema de saúde. As curvas suavizadas de percentis foram criadas pelo método LMS (least mean squares).

Resultados

692 nasceram em maternidades privadas, 2.150 em maternidade pública, 839 nasceram de parto vaginal e 1.311 parto cesáreo. O gênero masculino apresentou PC maior que o feminino nas IG de 37 a 42 semanas. Os RN de maternidades privadas tiveram PC maior que os de maternidade pública. Os nascidos de parto cesáreo tiveram PC maior que os de parto vaginal.

Conclusão

Importante consequência deste estudo foi que os resultados permitiram a criação de curvas e gráficos validados estatisticamente de aplicabilidade na prática clínica neonatal.
