“…After every 20 minutes, the parameters of interest were extracted from the report issued by the computed system in accordance with the criteria established by Dawes and Reedman. 15 Walking was considered to be at moderate intensity when the MHR during exercise remained between 60% and 80% of the maximum heart rate (HR) corrected for age. 16 In addition, subjective perceived exertion was measured using the Borg scale, 17 respecting the previously established limitations of each individual woman.…”

“…18 Short-term variation corresponds to the variation in bpm between each fetal heart beat, and its evaluation was only possible using the computer system. 15 Fetal movements were recorded using an event-marking device attached to a cardiotocograph operated by the pregnant woman. The woman was instructed to press the device every time she perceived a fetal movement.…”

Resumo Objetivo Determinar o efeito da caminhada em esteira sobre a frequência cardíaca materna (FCM) e parâmetros cardiotocográficos (batimentos cardiofetais basais [BCFs], movimentos ativos fetais [MAFs], número de acelerações e desacelerações e variabilidade de curta [STV] e longa [LTV] duração da frequência cardíaca fetal) em gestantes na 36a semana. Métodos Foi realizado um ensaio clínico não randomizado e aberto com 88 gestantes saudáveis submetidas a caminhada de moderada intensidade na esteira e a cardiotocografia computadoriza em 3 momentos de 20 minutos (antes, durante e após a caminhada). Resultados A média dos BCFs diminuiu durante a caminhada, retornando a níveis prévios (antes: 137 bpm; durante: 98 bpm; após: 140 bpm; p < 0,001), com bradicardia ocorrendo em 56% dos fetos nos primeiros 10 minutos do exercício, e em 47% após 20 minutos. A bradicardia fetal não foi observada em outros momentos (antes ou depois). As médias da STV e da LTV foram 7,9, 17,0 e 8,0 milissegundos (p < 0,001) e 7,6, 10,7 e 7,6 bpm (p = 0,002) antes, durante e após a caminhada, respectivamente. A média dos números dos MAFs em 1 hora foi 29,9, 22,2 e 45,5, respectivamente, nos três momentos (p < 0,001). Nas mulheres com sobrepeso/obesidade, a média da FCM foi menor (p = 0,02). Após a análise de regressão logística, duas variáveis permaneceram significativamente associadas a bradicardia: aptidão maternal na 28a semana de gravidez (efeito protetor) e peso materno (aumento do risco). Conclusão Em fetos saudáveis, o exercício físico mostrou-se seguro, uma vez que, embora os BCFs e os MAFs diminuam durante a caminhada na esteira, foi observado um aumento da SVT e da LTV.

“…The CTG trace is influenced by different variables such as: gestational risk factors, maternal habitus, and different indications for testing [2,4,5]. Some researchers also highlighted a possible variability of the CTG trace considering the ethnicity [6][7][8][9]. The increasing multi-ethnicity of our society could independently impact on several etiopathologies and outcomes of treatment: the relationship between ethnic group and fetal monitoring features is important in clinical practice [6,10].…”

“…The analysis of ethnic differences is very interesting, considering that previous studies seems to have more closely analyzed the white population than others [11,12]. In literature, data about this topic have reported less variable CTG traces in black women's fetuses than in other ethnic groups [6,7,9,13]. In studies published so far, CTGs have been analyzed for periods not including labour and have been limited to black versus white group comparisons.…”

Objective. Our society is becoming increasingly more multi-ethic. This fact could have an effect on several etiopathologies and outcomes of treatment. Therefore, there might also be an effect on the obstetric field. Cardiotocography is the most common way to assess fetal well-being in labour and some researchers also highlighted a possible variability of the CTG trace considering the ethnicity. The main aim of this study was to analyze whether different ethnicities might cause differences in the analysis of CTG traces and therefore influence clinical conduct. Patients and Methods. This is a descriptive cross-sectional research comparing CTGs performed during labour. Our sample is constituted by pregnant women at 37-42 weeks in a Maternal-Fetal Medical Center in Northern Italy (A.O.U. Maggiore della Carità, Novara), divided into different groups according to the patient's and her partner's ethnicity. Results. No statistically significant maternal or neonatal differences were observed between the different groups. Neonatal sex was equally distributed. The Apgar index was in the normal range for all groups at both one minute and five minutes, except for two newborns. There were no statistically significant differences in the fetal weight. Almost all women delivered vaginally. Black group showed 4 minutes more of reduced variability (on average) than other groups. No significant differences occurred in the CTGs parameters between the different ethnic groups of women in labour. Conclusions. Our results would seem encouraging about the use of CTG with equal expectations for all patients, regardless of ethnicity. This is the reason why our research could have useful implications in clinical choices: the CTG trace remains a valid tool for obstetric decision making for all women of any ethnic group.
