abstract: The object of this study is to charac terize the effect of focused ultrasound stimulation (FUS) on the rat ce rvix which has been observed to speed its ripening during pregnancy. Ce rvical ripening is required for successful fetal delivery. Timed-pregnant Sprague-Dawley rats (n=36) were used. On day 14 of gestation, the FUS system was placed on the body surface of the rat over the cervix and ultrasound energy was applied to cervix for variable times up to 1 hour in the control group, the FUS system was placed on rats but no energy was applied. Daily measurement of cervix light-induced florescence (LIF, photon counts of collagen x-bridge fluorescence) were made on days 16 of gestation and daily until spont-aneous delivery (day22) to estimate changes in cervical ripening. We found that pulses of 680 KHz ultrasound at 25 Hertz, 1 millisecond pulse duration at 1W/cm^2 applied for as little as 30 minutes would immediately afterwards show the cervix to hav e ripened to the degree seen just before delivery on day 22. Delivery times, fetal weights and viability were unaffected in the FUS-treated animals. / Dissertation/Thesis / M.S. Bioengineering 2012

Sujeitos e métodos: Foi realizado um estudo prospectivo, randomizado e do tipo ensaio clínico. Trinta e sete mulheres com gestação de baixo risco foram randomizadas para o preparo de colo uterino, com sonda de Foley, em dois grupos: ambulatorial (n=17) e internação (n=20). Os principais desfechos avaliados foram: índice de Bishop final, número de gestantes que modificaram o índice de Bishop de desfavorável para favorável, tipo de parto, uso de ocitocina, tempo de internação, morbidade materna e neonatal grave, óbito neonatal, taquissistolia com alteração da frequência cardíaca fetal e Apgar de quinto minuto ≤ 7. Para a análise estatística foram utilizados o teste de qui-quadrado para comparar proporções e o teste t de Student para a comparação de médias. O nível de significância estabelecido foi de 5% ( = 0,05). Resultados: Não houve diferença estatística significativa entre os dois grupos quanto ao índice de Bishop final, tipo de parto, necessidade de uso de ocitocina, morbidade materna e neonatal grave, óbito neonatal, taquissistolia com alteração da frequência cardíaca fetal e Apgar de quinto minuto ≤ 7. Como esperado, as gestantes do grupo internação tiveram mais horas dentro do ambiente hospitalar do que as do grupo ambulatorial (77,7 horas no grupo ambulatorial versus 93,1 horas no grupo internação), entretanto não houve diferença estatística. Conclusão: Gestantes do grupo ambulatorial apresentaram os mesmos desfechos que gestantes do grupo internação, com diminuição do tempo de internação e, consequentemente, redução do custo de tratamento, além da possibilidade de permanecer maior tempo no conforto do lar e na convivência familiar. / Objective: To determine the effect of the use of the Foley catheter for the cervical ripening, in pregnant women treated on an outpatient basis versus hospitalization. Subjects and methods: A prospective, randomized clinical trial was conducted. Thirty-seven women with low-risk pregnancies were randomized to the cervical ripening with a Foley catheter in two groups: outpatient (n = 17) and hospitalization (n = 20). The main outcome measures were: Bishop's final index, number of pregnant women who modified Bishop's ratio from unfavorable to favorable, type of delivery, oxytocin use, hospitalization time, severe maternal and neonatal morbidity, neonatal death, tachysystole with alteration of Fetal heart rate and fifth-minute Apgar ≤ 7. For the statistical analysis the chi-square test was used to compare proportions and Student's t-test for comparison of means. The level of significance was set at 5% ( = 0.05). Results: There was no statistically significant difference between the two groups regarding the final Bishop index, type of delivery, need for oxytocin use, severe maternal and neonatal morbidity, neonatal death, tachysystole with altered fetal heart rate, and fifth-minute Apgar ≤ 7. As expected, the pregnant women in the hospitalization group had more hours within the hospital setting than the outpatient group (77.7 hours in the outpatient group versus 93.1 hours in the hospitalization group), however there were no statistical differences. Conclusion: Pregnant women in the outpatient group presented the same outcomes as pregnant women in the hospitalization group, with a reduction in the length of hospital stay and, consequently, a reduction in the cost of treatment, as well as the possibility of remaining longer in the comfort of the home and in the family support.
