Implementation of sonopartogram: multicenter feasibility study.

OBJECTIVES: Well-established clinical practice to assess progress in labor involves routine abdominal palpation and vaginal examination (VE). However, VE is subjective, poorly reproducible and painful for women. In this study, our aim is to evaluate the feasibility of systematically integrating transabdominal and transperineal ultrasound assessment of fetal position, psAOP, HPD and SCD to monitor labor progress in women undergoing induction of labor (IOL). We also aim at determining if ultrasound can reduce women's pain during examinations. METHODS: Women were recruited as they presented for IOL in three maternity units. Ultrasound assessments were performed in 100 women between 37+0 and 41+6 weeks' gestation. A baseline combined transabdominal and transperineal scan was performed, including the assessment of fetal biometry, umbilical artery and middle cerebral artery Dopplers, amniotic fluid index (AFI), fetal spine and occiput positions, psAOP, HPD, SCD, and cervical length. Intrapartum scans were performed instead of VEs according to protocol. Participants were asked to indicate their level of pain by verbally giving a pain score from 0 - 10 (with 0 representing no pain) during assessment. The repeated measures data were analyzed by mixed effect models to identify the significant factors that affected the relationship between psAOP, HPD, SCD and mode of delivery. RESULTS: 223 intrapartum ultrasound scans with a median of 2 scans per participant (interquartile range (IQR) = 1 - 3), and 151 VEs were performed with a median of 1 per participant (IQR = 0 - 2). There were no adverse fetal or maternal outcomes. After excluding those with epidural anesthesia during examination, median pain score for intrapartum scan was 0 (IQR = 0 - 1) and 3 for VE (IQR = 0 - 6). Cesarean delivery and epidural anesthesia were significantly associated with slower rate of change in psAOP, HPD and SCD. Maternal height, parity and neonatal birth weight did not affect ultrasound measurements of labor progress. CONCLUSIONS: Comprehensive transabdominal and transperineal ultrasound assessment can be successfully used to assess progress in labor and can reduce the level of pain experienced during examination. Ultrasound assessment may be able to replace some transabdominal and VE examinations during labor. This article is protected by copyright. All rights reserved.

Parir después de los 50 años. Estudio piloto observacional / Birth over 50: A pilot observational study

Objetivos: Evaluar si existe una mayor tasa de resultados obstétricos adversos, incontinencia urinaria posparto y problemas sexuales entre las mujeres que dan a luz después de los 50 años.Material y métodos: Estudio observacional ambispectivo de un solo centro. Se registraron la tasa de parto por cesárea, la diabetes gestacional, la preeclampsia, la restricción del crecimiento intrauterino (RCIU), la prematuridad, la incontinencia urinaria (Cuestionario de incontinencia en formato corto [ICIQ-SF]) y la disfunción sexual (índice de función sexual femenina [FSFI-6]). Resultados: Veinticinco (0,06%) de 38.510 nacimientos ocurrieron en mujeres mayores de 50 años durante el período de estudio en nuestro centro. Hubo 16 (64%) partos por cesárea. Siete (28%) mujeres padecieron diabetes gestacional. Se diagnosticó preeclampsia en 3 (12%) mujeres. Hubo 5 (20%) casos de RCIU. Hubo 5 (20%) partos prematuros. Las diferencias en la tasa de parto por cesárea, diabetes gestacional y RCIU entre el grupo de estudio y la población total fueron estadísticamente significativas. Los resultados de los cuestionarios ICIQ-SF y FSFI-6 se obtuvieron de 17 mujeres. Se encontró algún grado de incontinencia urinaria en 7 (41,1%) y disfunción sexual en 9 (52,9%) mujeres. Conclusiones: Los embarazos en mujeres mayores de 50 años parecen estar asociados con una mayor tasa de diabetes gestacional, RCIU y preeclampsia. Hay una alta prevalencia de incontinencia urinaria y problemas sexuales entre estas mujeres.(AU)

Objectives: To assess whether there is a higher rate of adverse obstetric outcomes, postpartum urinary incontinence, and sexual problems among women who give birth over 50. Material and methods: A single-center ambispective observational study. Rate of cesarean birth, gestational diabetes, preeclampsia, intrauterine growth restriction (IUGR), prematurity, urinary incontinence (Incontinence Questionnaire Short Form [ICIQ-SF]), and sexual dysfunction (Female Sexual Function Index [FSFI-6]) were recorded. Results: Twenty-five (0.06%) of 38,510 births occurred in women over 50 during the study period. There were 16 (64%) cesarean births. Seven (28%) women had gestational diabetes. Preeclampsia was diagnosed in 3 (12%) women. There were 5 (20%) cases of IUGR. There were 5 (20%) preterm births. The differences in the rate of cesarean birth, gestational diabetes, and IUGR between the study group and the total population were statistically significant. The results of the ICIQ-SF and FSFI-6 questionnaires were obtained from 17 women. Some degree of urinary incontinence was found in 7 (41.1%) and sexual dysfunction in 9 (52.9%) women. Conclusions: Pregnancies in women over 50 may be associated with a higher rate of gestational diabetes, IUGR, and preeclampsia. There is a high prevalence of urinary incontinence and sexual problems among these women.(AU)

Obstetric perinatal and maternal outcomes of monochorionic diamniotic twins following assisted reproductive techniques. Retrospective observational study / Resultados obstétricos perinatales y maternales en gemelos monocoriales diamnióticos conseguidos mediante técnicas de reproducción asistida. Estudio observacional retrospectivo

Introduction: Multiple and specifically monochorionic diamniotic (MCDA) pregnancies are related to maternal and foetal complications. The aim of this study is to evaluate obstetric and perinatal outcomes of MCDA after assisted reproductive techniques (ART). Methods: This is a case-control study comparing 23 MCDA twin pregnancies after ART (ART-MCDA) and 75 spontaneous MCDA (sMCDA). Maternal, obstetric, foetal, and perinatal outcomes variables including maternal age, prematurity, TTTS, sIUGR, TAPS, PROM, and neonatal weight were compared. Results: mean maternal age is higher in the ART-MCDA pregnancies, 38.0±.6 (OR=1.32(1.13–1.53)). Neonates weighing between 1500 and 2500g are more frequent in the sMCDA group and those weighing >2500g in the ART group (OR=0.47(0.22–0.97)). Foetuses born at between 32 and 37 weeks are more frequent in sMCDA pregnancies and those born >37 in the TRA group (OR=0.27(0.09–0.80)). These differences are lost when we adjust the results by maternal age. There were no differences in maternal, obstetric, or foetal complications. Conclusions: ART-MCDA are not associated with a higher number of maternal, obstetric or foetal complications if they are adjusted by maternal age. When they are not adjusted by maternal age, there would be better outcomes such as premature and neonatal weight in the ART group.(AU)

Antecedentes: El incremento de las técnicas de reproducción asistida (TRA) ha supuesto un aumento de las gestaciones gemelares en general, pero también de las monocoriales biamnióticas (MCBA), que se asocian a diversas complicaciones maternofetales. Estas complicaciones están bien estudiadas en gestaciones espontáneas, pero no en aquellas conseguidas mediante una TRA. Objetivo: Comparar la incidencia de complicaciones maternas, fetales, obstétricas y perinatales en gestaciones MCBA conseguidas de forma espontánea frente a aquellas conseguidas mediante TRA. Materiales y métodos: Estudio de casos-controles retrospectivo. Se han analizado 98 gestaciones gemelares MCBA controladas en la Unidad de Medicina Materno-Fetal del Servicio de Obstetricia del Hospital La Paz de Madrid entre los años 2015 y 2020. Resultados: La media de edad de las madres de las gestaciones MCBA conseguidas mediante TRA es mayor (OR=1,32 [1,13-1,53]). Los recién nacidos de peso entre 1.500-2.500g son más frecuentes en las gestaciones MCBA conseguidas de forma espontánea y los de >2.500g en las de TRA (OR=0,47 [0,22–0,97]). Los recién nacidos entre las 32-37 semanas son más frecuentes en las gestaciones gemelares MCBA espontáneas y los recién nacidos de >37 semanas en las de TRA (OR=0,27 [0,09-0,80]). Cuando estos resultados se ajustan por la edad materna dejan de ser estadísticamente significativos. Conclusiones: Las TRA no conllevan un aumento de las complicaciones en las gestaciones MCBA cuando se ajustan los resultados por la edad materna. Si no se ajustasen por la edad materna, las gestaciones MCBA conseguidas mediante TRA tendrían mejores resultados, con menos prematuridad y mayor peso del neonato.(AU)

Influence of introducing a maneuverable vacuum extractor cup on maternal hospital stay after instrumental birth. Retrospective cohort study / Repercusión de la introducción de la ventosa obstétrica maniobrable en un centro hospitalario sobre la estancia materna tras parto instrumental. Estudio de cohortes retrospectivo

Objectives: The aim of our study is to evaluate the impact of the introduction of a maneuverable vacuum extractor cup on the length of hospital stay after assisted vaginal birth in nulliparous women in a hospital where no vacuum devices were used. Methods: This single center retrospective analytical study included two groups of nulliparous women who had undergone an assisted vaginal birth. The 2 groups differ according to the availability or not of a maneuverable vacuum extractor cup. The first group includes the last 54 instrumental births until May 2017, when only obstetric forceps and Thierry's spatulas were available in our center; the second group includes the first 54 instrumental births since May 2018 in our center, when obstetric forceps, Thierry's spatulas and maneuverable vacuum extractor cup were available. Maneuverable vacuum extractor cups had been available for 12 months in the second group. Results: In the no vacuum cup group, Kjelland forceps and Thierry's spatulas were used in 29 (53.7%) and 25 (46.3%) of the 54 assisted vaginal births, respectively. In the vacuum available group, a vacuum cup was chosen in 30 (55.6%), Kjelland forceps were used in 18 (33.3%) and Thierry's spatulas in 6 (11.1%) of the assisted vaginal births. 22 women (40.7%) had a postpartum hospital stay longer than 3 days in the group with no maneuverable vacuum extractor cup availability, versus 3 women (5.6%) in the group with availability of a maneuverable vacuum extractor cup, p<0.001. Average postpartum hospital stay length was 3.17±0.803 days versus 2.81±0.585, p<0.001. There was also a significant reduction in the number of episiotomies. Conclusion: The introduction of a maneuverable vacuum extractor cup in a center where only forceps and Thierry's spatulas had been used resulted in a decrease in postpartum hospital stay in nulliparous women.(AU)

Objetivos: El objetivo de nuestro estudio es evaluar el impacto de la introducción de una ventosa obstétrica con cazoleta maniobrable en la duración de la estancia hospitalaria tras parto instrumental en mujeres nulíparas en un hospital donde no se utilizaban ventosas obstétricas. Métodos: Este estudio de cohortes retrospectivo unicéntrico incluyó 2 grupos de mujeres nulíparas sometidas a parto instrumental. Los 2 grupos se diferencian según la disponibilidad o no de ventosa obstétrica en el centro. El primer grupo se compone de las últimas 54 mujeres a las que se les asistió un parto instrumental hasta mayo del 2017, cuando solo había disponibilidad de fórceps obstétricos y espátulas de Thierry en nuestro centro; el segundo grupo se compone de las primeras 54 mujeres a las que se les asistió un parto instrumental desde mayo del 2018 en nuestro centro, cuando había disponibilidad de fórceps obstétricos, de espátulas de Thierry y de ventosa obstétrica con cazoleta maniobrable (esta última desde hacía 12 meses). Resultados: En el grupo sin disponibilidad de ventosa obstétrica, se utilizaron fórceps de Kjelland y espátulas de Thierry en 29 (53,7%) y 25 (46,3%) de los 54 partos instrumentales, respectivamente. En el grupo con disponibilidad de ventosa, se usó la ventosa en 30 (55,6%), fórceps de Kjelland en 18 (33,3%) y espátulas de Thierry en 6 (11,1%) de los partos instrumentales; 22 mujeres (40,7%) tuvieron una estancia hospitalaria tras el parto mayor de 3 días en el grupo sin disponibilidad de ventosa, frente a 3 mujeres (5,6%) en el grupo con disponibilidad de ventosa, p<0,001. La duración media de la estancia hospitalaria tras el parto fue de 3,17±0,803 días frente a 2,81±0,585, p<0,001. También hubo una reducción significativa en el número de episiotomías.(AU)

Use of intrapartum ultrasound in the prediction of complicated operative forceps delivery of fetuses in non-occiput posterior position.

OBJECTIVE: To evaluate the hypothesis that intrapartum ultrasound (ITU) measurements, including the angle of progression (AOP), progression distance (PD) and head direction (HD), can predict complicated forceps delivery in non-occiput posterior deliveries. METHODS: In this prospective observational study, a single operator performed ITU on 30 patients with an indication for operative forceps delivery. Managing obstetricians were blinded to the results. ITU was performed just before blade application, between contractions and concurrently with contractions and active pushing. Forceps delivery was classified as complicated when one or more of the following situations occurred: three or more tractions; a subjective impression of a difficult or failed application; a third-degree or higher perineal tear; significant bleeding during the episiotomy repair; major tear; significant traumatic neonatal lesion. RESULTS: Twenty-one forceps deliveries were classified as uncomplicated and nine were complicated. The strongest predictor of a complicated forceps delivery, calculated using the area under the receiver-operating characteristics curve (AUC), was the AOP between contractions (AOP1) (AUC = 98.9%). The best cut-off for predicting a difficult forceps delivery was an AOP1 of 138° (sensitivity = 85.7%, specificity = 100%). The best predictive model included both the AOP1 and the HD during a contraction with active pushing (HD2). CONCLUSION: The sonographic parameters AOP and HD can be used to predict complicated operative forceps delivery in fetuses in non-occiput posterior position.
