ABSTRACT
INTRODUCTION@#There has been a global decrease in operative vaginal deliveries, with a marked shift towards the vacuum extractor. However, little is known about the trends in operative vaginal delivery in Singapore.@*METHODS@#A retrospective study was conducted on all operative vaginal deliveries performed from 2012 to 2017 at Singapore General Hospital (SGH). Maternal outcomes in terms of postpartum haemorrhage and obstetric anal sphincter injuries were compared between forceps- and vacuum-assisted deliveries. Neonatal outcomes in terms of neonatal intensive care unit (NICU) admission and clinically significant neonatal events were compared. The instrument preference of obstetricians was analysed.@*RESULTS@#A total of 906 consecutive operative vaginal deliveries were included in the study, comprising 461 forceps- and 445 vacuum-assisted deliveries. The rate of operative vaginal delivery was maintained at approximately 10% from 2012 to 2017. Neonatal cephalohematomas were more common after vacuum-assisted deliveries. Other maternal and neonatal outcomes did not differ significantly between the two groups. Clinically significant neonatal events were mostly due to shoulder dystocia, whereas all cases of NICU admissions were not directly related to the mode of delivery. Obstetricians' choice of instrument appeared to reflect personal preference and was not affected by the year of graduation.@*CONCLUSION@#The rates of neonatal and maternal morbidity were low at SGH. Overall instrument use of forceps and vacuum was balanced, and proficiency in both was demonstrated by all operators. Operative vaginal delivery remains an essential skill in facilitating safe vaginal delivery, which should be maintained to keep Caesarean section rates in check.

Objetivos: evaluar la frecuencia del parto instrumentado en Colombia y por regiones entre el 2015 y 2019. Materiales y métodos: estudio de corte transversal a partir de registros poblacionales. Se incluyeron los registros de mujeres con edad gestacional mayor a 28 semanas y parto vaginal. Muestreo consecutivo. La información se obtuvo a partir del certificado de nacido vivo del Departamento Administrativo Nacional de Estadística (DANE). Se realizó la descripción de las variables sociodemográficas y clínicas. La frecuencia del parto instrumentado fue calculada y descrita por año y departamento. Resultados: se incluyeron 3.224.218 registros de recién nacidos vivos. De estos, 1.719.405 (53,33 %) correspondieron a partos vaginales, y 1.468.726 (45,55 %) a partos por vía cesárea. La frecuencia nacional del parto instrumentado entre el 2015 y 2019 fue de 36.087 nacimientos (1,11 %); Antioquia y Bogotá, D.C. fueron los lugares con mayor ocurrencia, 16.201 (4,5 %) y 13.686 (2,52 %), respectivamente. Conclusiones: el parto vaginal instrumentado es la vía de parto con menor ocurrencia en Colombia con tendencia a la disminución. La formación en este recurso para el uso durante el trabajo de parto no debe perderse en la formación del profesional de salud, especialmente en los programas de Ginecología y Obstetricia. Se debe evaluar si el aumento en el adecuado uso de esta técnica puede disminuir la tasa de cesáreas observadas actualmente, así como describir los escenarios clínicos donde su uso es seguro para la madre y el feto. Se requieren estudios prospectivos, pues pueden permitir establecer las causas del descenso en el uso de esta herramienta obstétrica, los resultados maternos y perinatales en términos de su riesgo/beneficio.
Objectives: To assess the frequency of instrumented delivery in Colombia and by regions between 2015 and 2019. Materials and methods: Cross-sectional study based on population registries. Records of women with a gestational age of more than 28 weeks and vaginal delivery were included. Consecutive sampling was used. The information was taken from live birth certificates of the National Administrative Department of Statistics (DANE). Sociodemographic and clinical variables were described. The frequency of instrumented deliveries was calculated and described by year and by department. Results: Overall, 3,224,218 live birth records were included. Of these 1,719,405 (53.33 %) were vaginal deliveries and 1,468,726 (45.55 %) were cesarean births. At a national level, the frequency of instrumented deliveries between 2015 and 2019 was 36,087 births (1.11 %); Antioquia and Bogotá, D.C. were the places with the highest occurrence, with 16,201 (4.5 %) and 13,686 (2.52 %), respectively. Conclusions: The occurrence of instrumented vaginal delivery in Colombia is the lowest and tends to diminish. Training of healthcare professionals in this approach during labor must not be abandoned, particularly in Obstetrics and Gynecology training programs. Further studies should be conducted to determine whether the increased adequate use of this technique could contribute to a lower rate of cesarean sections, and also to describe the clinical setting in which its use is safe for both the mother and the fetus. Prospective studies are required to identify the causes leading to the lower use of this obstetric tool as well as the risks and benefits in terms of maternal and perinatal outcomes.

In this study, 15 second-year resident doctors who had standardized training of OBGYN were taken as research subjects to discuss the effect of training resident doctors with obstetrics forceps by using simulation teaching method. The simulation teaching process includes theoretical study, theoretical examination, simulation teaching of forceps skills and Assessment of forceps skills. In theoretical study section: before learning to use forceps, the students acquired the theoretical knowledge by flipped teaching micro-video mode. In theoretical examination section: the mastery of basic clinical knowledge of using forceps was evaluated through online assessment. In simulation teaching of forceps skills: students who scored 8/10 points were admitted to enter the simulation teaching process, and they had practical training of scenario simulation skills in Clinical Skills Center. In assessment of forceps skills: the mastery of forceps skills was evaluated by standardized forceps delivery procedure items. The results showed that the students in the simulation teaching group had excellent teaching assessment results, and the resident doctors had more confidence in operating forceps independently, and the teaching effect was ideal, which could further promote the simulation teaching of obstetric clinical skills.
