Ultrassonografia tridimensional da funcionalidade dos músculos do assoalho pélvico de gestantes com diabete melito gestacional

Abstract

Objetivo: Investigar o efeito do diabetes mellitus gestacional (DMG) na função do músculo do assoalho pélvico (MAP) durante a gravidez pelo ultrassom tridimensional (3D) transperineal. Método: Foram avaliadas 38 mulheres com DMG e 45 normoglicêmicas (NG) entre 24-30 e 36-40 semanas de gestação. A funcionalidade dos MAP foi determinada pela contração e distensão. Os resultados da contração foram descritos como "contratilidade" e da distensão como "distensibilidade". Para analisar a funcionalidade dos MAP de forma ampla determinamos o "Índice de Mobilidade". As imagens foram adquiridas pelo ultrassom 3D transperineal, em repouso, na contração dos MAP e em manobra de Valsalva. A contratilidade e a distensibilidade dos MAP foram demonstradas por valores absolutos e índices de funcionalidade. Os índices foram determinados pela diferença das dimensões do hiato do elevador (HE) entre a contração e o repouso e, entre a distensão e o repouso. O Índice de Mobilidade foi determinado pelo intervalo entre a distensão e a contração. Resultados: Os dados demográficos foram homogêneos. O grupo DMG apresentou diferenças na contratilidade, distensibilidade e mobilidade para a maioria das dimensões em relação ao grupo NG, entre 24-30 e 36-40 semanas de gestação. O progresso da distensão ao longo da gestação no grupo GDM demonstrou menor distensibilidade muscular do diâmetro anteroposterior do HE (HEap) (P = 0,000) e da área do HE (HEárea) (P = 0,000), caracterizando um músculo rígido. O progresso entre 24-30 e 36-40 semanas de gestação, mostrou aumento no grupo NG do diâmetro transverso do HE (HEt) (P = 0,046) e da HEárea (P = 0,000) no Índice de Distensibilidade; e aumento do HEap (P = 0,032), do HEt (P= 0,048) e da HEárea (P = 0,000) no Índice de Mobilidade. Em contraste, o grupo DMG mostrou diminuição no Índice de Contratilidade, Índice de Distensibilidade e Índice de Mobilidade da HEárea (P = 0,000; P= 0,000 e P= 0,000, respectivamente). Conclusão: O DMG diminuiu a função do MAP na contratilidade, distensibilidade e mobilidade na 24-30 semanas de gestação e 36-40 semanas de gestação e no progresso da gestação avaliado pelo ultrassom 3D transperineal.

Objective: To investigate the effect of gestational diabetes mellitus (GDM) on pelvic floor muscle (PFM) contractility and distensibility at two-time points of pregnancy by transperineal three-dimensional (3D) ultrasound. Methods: 38 GDM and 45 normoglycemic (NG) pregnant women were assessed at 24-30 and 36-40 weeks of gestation. PFM function was performed by contraction and distension. The functionality indexes results were described on contraction as “contractility” and on distention as “distensibility”. To analyze the PFM function widely, a “Mobility Index” was developed. The images acquired using 3D transperineal ultrasound (3D) were taken at rest, during PFM contraction and on Valsalva maneuver. The contractility and distensibility of the PFM were demonstrated by absolute values and function indexes that were determined by the difference between LH dimensions during contraction or distension and those at rest. Mobility Index was performed by the interval between distension and contraction. Results: Demographic data were homogeneous. The GDM group at 24-30 and 36-40 weeks of gestation showed differences in the contractility, distensibility and mobility for most all dimensions compared to NG. The distension progress of the GDM group demonstrated less muscle distensibility in anteroposterior diameter (LHap) (P=.000) and in LH area (LHarea) (P=.000). The gestation progress from 24-30 to 36-40 weeks of gestation, showed in the NG group increase on transverse diameter (LHrl) (P=.046) and on LHarea (P=.000) Distensibility Indexes; and increase on LHap (P=.032), LHrl (P=.048) and LHarea (P=.000) Mobility Indexes. In contrast, the GDM group showed decrease on LHarea Contractility Index, Distensibility Index and Mobility Index (P=.000; P=.000 and P=.000, respectively). Conclusion: GDM decreased PFM function in the contractility, distensibility, and mobility at 24-30 and 36-40 weeks of gestation and on gestational progress by 3D ultrasound.
