Title in Portuguese
"Cardiotocografia estimulada em gestações de baixo risco: estudo comparativo da resposta cardíaca fetal à estimulação vibratória e sônica"
Keywords in Portuguese
Cardiotocografia
Estimulação acústica
Freqüência cardíaca
Monitorização fetal
Vibração
Abstract in Portuguese
Trata-se de estudo prospectivo, comparativo da resposta da freqüência cardíaca fetal (FCF) à estimulação vibratória e sônica, quanto à amplitude e duração, em 113 fetos de gestações de baixo risco. A população estudada foi discriminada em quatro grupos: 1) 25 semanas a 28 semanas e seis dias; 2) 29 semanas a 32 semanas e seis dias; 3) 33 semanas a 36 semanas e seis dias e 4) 37 a 42 semanas. Comparando-se a amplitude e a duração da resposta da FCF na faixa três e na faixa quatro, a resposta à estimulação vibratória foi menor que a sônica. Nas faixas um e dois não houve diferença nas respostas. Conclui-se que a estimulação vibratória promove resposta fetal (FCF) menos intensa com amplitude e duração de resposta menor quando comparada à estimulação sônica em faixa de idade gestacional mais tardia

Abstract in English
This prospective study compares the response in terms of fetal heart rate acceleration after vibratory and sonic stimulation, in a sample of 113 fetuses of low-risk pregnancies. The study population was divided into four groups according to gestational age: group 1 - 25 weeks to 28 weeks and 6 days; group 2 - 29 weeks to 32 weeks and 6 days; group 3 - 33 weeks to 36 weeks and 6 days, and group 4 - 37 to 42 weeks. Comparing the amplitude and duration of the cardioacceleratory response between group 3 and 4, the response after vibratory stimulation was lower than sonic. In the groups 1 and 2, the response was similar. The study concludes that vibratory stimulation promotes a less intense response with amplitude and duration lower than sonic stimulation in latter gestational age
