Resumo: | Objectives: To assess the fetal response by use of doppler study in low risck pregnant women submitted to isometric handgrip test. Methods: A cross-sectional experimental study was conducted on 50 healty pregnant women with gestational age between 26 and 36 weeks. The patients were submited to isometric handgrip, and data were collected from the mother (blood pressure, heart rate and Doppler velocimetry for the uterine arteries) and from the fetus (heart rate, Doppler velocimetry for the umbilical artery, middle cerebral artery and ductus venosus). All variables were collected before, during and after the isometric handgrip. Results: There was a significant increase (p<0,001) of systolic blood pressure (pre-isometric 113,13±9,92, trans-isometric 117,13±10,24, post-isometric 112,43±9,87) and maternal heart rate (pre 87,52±14,10, trans 97,61±14,83, post 85,13±13,24), and a significant decrease of pulsatility index (pre 0,63±0,15, trans 0,56±0,15, post 0,65±0,17, p=0,001), resistance index (pre 0,44±0,08, trans 0,40±0,07, post 0,45±0,08, p=0,001) and systole/diastole ratio (pre 1,81±0,26, trans 1,69±0,24, post 1,85±0,29, p<0,001) of the left uterine artery. These maternal variables changed significantly only during isometry, but not when pre and post data were compared. There was no change on the fetal parameters when compared before, during or after isometric handgrip. Although there was no significant reduction of pulsatility index, resistance index and systole/diastole ratio values for the right uterine artery during the isometric handgrip, it had the same behavior of the left uterine artery, showing that there was a bilateral vasodilatation when maternal blood pressure and heart rate rise. This vasodilatation of the uterine arteries seems to be a compensatory mecanism, preserving the hemodynamic homeostasis of pregnancy, which is confirmed by the fact of there was no change on the fetal hemodynamic parameters. Conclusion: The isometric handgrip test didn’t interfered in the fetal hemodynamics, in low risk pregnant women. |

Metodologia: Estudo experimental transversal, com amostra de 46 gestantes saudáveis com idade gestacional entre 26 e 36 semanas, que foram submetidas a teste isométrico com dinamômetro de preensão manual, para coleta de parâmetros hemodinâmicos maternos (pressão arterial, frequência cardíaca e Doppler de artérias uterinas) e fetais (frequência cardíaca, Doppler de artéria umbilical, artéria cerebral média e ducto venoso), antes, durante e após a isometria. Resultados: Houve aumento significativo com p<0,001 da pressão arterial (PA) sistólica (pré- isometria 113,13±9,92, trans-isometria 117,13±10,24, e pós-isometria 112,43±9,87) e da frequência cardíaca (FC) materna (pré 87,52±14,10, trans 97,61±14,83, e pós 85,13±13,24), e redução significativa do índice de pulsatilidade (IP) (pré 0,63±0,15, trans 0,56±0,15, e pós 0,65±0,17, com p=0,001), índice de resistência (IR) (pré 0,44±0,08, trans 0,40±0,07,e pós 0,45±0,08, com p=0,001) e relação sístole/diástole (S/D) (pré 1,81±0,26, trans 1,69±0,24, e pós 1,85±0,29, com p<0,001) da artéria uterina (AU) esquerda. Estas variáveis se alteraram significativamente apenas durante a isometria, e não quando comparados os valores pré e pós- isometria Não houve diferença significativa nos parâmetros fetais quando comparados antes, durante ou após o teste isométrico. Apesar de não termos encontrado redução significativa dos valores de IP, IR e S/D na AU direita durante a isometria, esta seguiu o mesmo comportamento que a AU esquerda, mostrando vasodilatação bilateral quando houve alteração de PA e FC maternas. Este mecanismo de vasodilatação das AU parece ser compensatório, preservando a homeostase hemodinâmica da gravidez, o que se comprova por não haver modificação dos parâmetros hemodinâmicos fetais. Conclusão: O teste isométrico não teve repercussão sobre a hemodinâmica fetal, em gestantes saudáveis de pré-natal de baixo risco.Universidade Federal de Santa MariaBrasilCiências da SaúdeUFSMPrograma de Pós-Graduação em Ciências da SaúdeCentro de Ciências da SaúdeGallarreta, Francisco Maximiliano Pancichhttp://lattes.cnpq.br/6610643089938647Haeffner, Léris Salete BonfantiXXXXXXXXXXXXXXXCoutinho, Renato XavierXXXXXXXXXXXXXXXXXXSoares, Karina Biaggio2021-04-19T17:43:22Z2021-04-19T17:43:22Z2018-02-19info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://repositorio.ufsm.br/handle/1/20625porAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/openAccessreponame:Manancial - Repositório Digital da UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSM2021-04-20T06:00:42Zoai:repositorio.ufsm.br:1/20625Biblioteca Digital de Teses e Dissertaçõeshttps://repositorio.ufsm.br/ONGhttps://repositorio.ufsm.br/oai/requestatendimento.sib@ufsm.br||tedebc@gmail.comopendoar:2021-04-20T06:00:42Manancial - Repositório Digital da UFSM - Universidade Federal de Santa Maria (UFSM)false |
