ABSTRACT

La amenaza de parto prematuro se considera hoy en día como una urgencia obstétrica en la que, si no se realiza alguna intervención desemboca en un parto prematuro. Por tanto, una vez confirmado el diagnóstico, el tratamiento consiste en la administración de tocolíticos, cuyo objetivo principal es el retraso del nacimiento ganando tiempo para administrar maduración pulmonar y neuroprotección con el fin de disminuir el síndrome de dificultad respiratoria y parálisis cerebral, así como lograr el traslado de la madre a un centro de referencia, si fuere el caso. La elección de un fármaco u otro debe basarse en una adecuada valoración riesgo-beneficio, una vez tenida en cuenta la situación clínica de cada gestante. El empleo de tocolíticos al inicio de este proceso es esencial y en esta revisión se analiza la información disponible sobre su uso en la amenaza de parto prematuro


The preterm labour is now considered an obstetric emergency in which, if no intervention is performed, it leads to premature delivery. Therefore, once the diagnosis has been confirmed, the treatment consists of the administration of tocolytics, whose main objective is to delay the birth by gaining time to administer lung maturation and neuroprotection in order to reduce respiratory distress syndrome and cerebral palsy, as well as to achieve the transfer of the mother to a reference center, if necessary. The choice of one drug or another should be based on an adequate risk-benefit assessment, once the clinical situation of each pregnant woman has been taken into account. The use of tocolytics at the beginning of this process is essential and in this review the available information on their use in threatened preterm labor is analyzed.

ABSTRACT

Resumen OBJETIVO: Reportar la experiencia en la práctica de cerclajes con indicación profiláctica y terapéutica en pacientes con embarazo único o múltiple, con insuficiencia cervical. Además, informar los días de gestación ganados y comparar las técnicas quirúrgicas con los cerclajes. MATERIALES Y MÉTODOS: Estudio retrospectivo, descriptivo, comparativo y transversal efectuado entre enero de 2011 y enero de 2018. Criterios de inclusión: pacientes a quienes se efectuó un cerclaje y el embarazo finalizó en nuestra unidad. Variables de estudio: edad, IMC, embarazos, abortos, días de gestación ganados, días en que se efectuó el procedimiento quirúrgico, semanas de gestación cumplidas a la finalización del embarazo, tiempo quirúrgico, medicamentos (tocolíticos y antibióticos), complicaciones a partir del cerclaje hasta la finalización del embarazo. Para el análisis descriptivo se utilizó el paquete estadístico IBM SPSS (versión 22); la distribución se obtuvo con t de Student, se aplicó la prueba de normalidad Shapiro-Wilk y las variables con distribución normal se analizaron, comparativamente, con ANOVA y las de distribución anormal con la prueba Kruskal-Wallis. RESULTADOS: Se analizaron 37 casos en los que el cerclaje prolongó 116.14 ± 47.4 días la gestación, con finalización promedio del embarazo a los 246.41 ± 26.54 días. El cerclaje Shirodkar fue superior: prolongó la gestación 134.69 días con finalización del embarazo a las 36 ± 2 semanas. CONCLUSIONES: En pacientes con insuficiencia cervical el cerclaje es una opción para prolongar el embarazo. La técnica Shirodkar tuvo márgenes de mayor seguridad hasta la finalización del embarazo (más de 34 semanas). El comportamiento en embarazos múltiples es similar, por lo que en caso de insuficiencia cervical debe aplicarse.


Abstract OBJECTIVE: To report the experience in the practice of cerclages with prophylactic and therapeutic indication in patients with single or multiple pregnancy, with cervical incompetence. In addition, report the days of pregnancy gained, compare surgical techniques and cerclages in single and multiple gestations. MATERIALS AND METHODS: Retrospective, descriptive, comparative and cross-sectional study carried out between January 2011 and January 2018. Inclusion criteria: patients who had a cerclage and the pregnancy ended in our unit. Study variables: age, BMI, pregnancies, abortions, days of gestation earned, days in which they were placed, weeks of gestation completed at the end of pregnancy, surgical time, medications (tocolytics and antibiotics), complications from the placement of the cerclage until the end of pregnancy. For the descriptive analysis the statistical package IBM SPSS (version 22) was used; the distribution was obtained with Student's t test, the Shapiro-Wilk normality test was applied and the variables with normal distribution were analyzed, comparatively, with ANOVA and those with abnormal distribution with the Kruskal-Wallis test. RESULTS: 37 cases were analyzed in which the placement of cerclage prolonged 116.14 ± 47.4 days gestation, with an average termination of pregnancy at 246.41 ± 26.54 days. The Shirodkar cerclage was superior: it extended gestation 134.69 days with the end of pregnancy at 36 ± 2 weeks. CONCLUSIONS: In patients with cervical incompetence cerclages are an option to prolong pregnancy. The Shirodkar technique had higher safety margins until the end of pregnancy (more than 34 weeks). The behavior in multiple pregnancies is similar, so in case of cervical incompetence should be applied.

ABSTRACT

Objetivo: Evaluar la efectividad de la progesterona natural micronizada administrada vía oral y del fenoterol administrado vía endovenosa, en el tratamiento de las pacientes con diagnóstico de amenaza de parto pretérmino. Métodos: Estudio experimental tipo ensayo terapéutico en pacientes que acudieron al Hospital Universitario de Caracas. Resultados: 15 pacientes del grupo estudio con progesterona presentaron resultados satisfactorios (X² = 155,837, df = 18); del grupo control, 13 pacientes con resultados satisfactorios (X² = 133,093, df = 18). La efectividad absoluta en el grupo de estudio fue de 0,68 contra 0,59 del grupo control (X² = 0,393; df = 1; P < 0,531). Conclusiones: Los tratamientos con progesterona natural micronizada y fenoterol demostraron ser inhibitorios de la dinámica uterina, a partir de la segunda hora de iniciado el tratamiento, evitando su progreso hacia trabajo de parto en un 90 %. La progesterona natural micronizada es efectiva en el tratamiento de la amenaza de parto pretérmino y se debe considerar su uso como alternativa terapéutica.


Objective: To evaluate the effectiveness of micronized natural progesterone administered orally and intravenously administered fenoterol in the treatment of patients with a diagnosis of preterm labor. Method: The type of therapeutic trial in patients attended at the Hospital Universitario de Caracas. Results: 15 patients in the progesterone study showed satisfactory results (X² = 155.837 df = 18); the control group, 13 patients with satisfactory results (X² = 133.093 df = 18). The absolute effectiveness in the study group was 0.68 against 0.59 in the control group (X² = 0.393 df = 1, P < 0.531). Conclusions: Treatment with micronized natural progesterone and fenoterol proved inhibitory uterine dynamics from the second hour of starting treatment preventing its progress toward labor by 90 %. The micronized natural progesterone is effective in the treatment of preterm labor and should be considered as an alternative therapeutic use.

ABSTRACT

El parto pretérmino es un gran problema de salud a escala mundial, con impacto directo en la morbilidad y mortalidad perinatal; por lo que actualmente el tratamiento con tocolíticos ha devenido un dilema. Ante tal situación, el autor de este artículo decidió revisar bibliografía actualizada sobre el tema, con vistas a describir las diferentes drogas -- mecanismos de acción, reacciones adversas, dosis, vías de administración y tiempo de utilización -- que se aplican para inhibir el parto pretérmino, así como los nuevos fármacos tocolíticos en estudio; de manera que los obstetras cuenten con la información necesaria que les permita seleccionar adecuadamente la droga, que se debe emplear con carácter individual y no poblacional.


Preterm delivery is a worldwide major health problem with direct impact on perinatal morbidity and mortality, so currently tocolytic therapy has become a dilemma. In such a situation, the author of this article decided to review current literature on the subject in order to describe different drugs -- mechanisms of action, side effects, dosage, route of administration and time of use -- administered to inhibit preterm delivery, as well as new tocolytics under study, so that obstetricians have the information necessary to enable them to properly select the drug to be used individually and not in the population.

ABSTRACT

O objetivo principal para o uso de uterolíticos no trabalho de parto prematuro é prolongar suficientemente a gestação para a administração materna de glicocorticoides e/ou realizar a transferência materna para um centro hospitalar terciário. As decisões sobre o uso e a escolha de uterolítico requerem o diagnóstico correto do trabalho de parto prematuro, o conhecimento da idade gestacional, das condições médicas materno-fetais, da eficácia, dos efeitos colaterais e do custo do medicamento. Todos os uterolíticos possuem efeitos colaterais e alguns deles são potencialmente letais. Os estudos sugerem que os agonistas de receptores beta-adrenérgicos, os bloqueadores de cálcio e os antagonistas de receptor de ocitocina são eficazes para prolongar a gestação por pelo menos 48 horas. Dos três agentes, o atosiban (antagonista de receptor de ocitocina) possui maior segurança, embora o custo seja elevado. O sulfato de magnésio não é eficaz para prolongar a gestação e apresenta efeitos colaterais importantes. Os inibidores da ciclooxigenase também apresentam efeitos colaterais significativos. Até o momento, não há evidências suficientes para se recomendar o uso de doadores de óxido nítrico para inibir o trabalho de parto prematuro. Não existem fundamentos para o emprego de antibióticos para evitar a prematuridade diante do trabalho de parto prematuro.


The main purpose of using uterulytic in preterm delivery is to prolong gestation in order to allow the administration of glucocorticoid to the mother and/or to accomplish the mother's transference to a tertiary hospital center. Decisions on uterolytic use and choice require correct diagnosis of preterm delivery, as well as the knowledge of gestational age, maternal-fetal medical condition, and medicine's efficacy, side-effects and cost. All the uterolytics have side-effects, and some of them are potentially lethal. Studies suggest that beta-adrenergic receptor agonists, calcium blockers and cytokine receptor antagonists are effective to prolong gestation for at least 48 hours. Among these three agents, atosiban (a cytokine receptor antagonist) is safer, though it presents a high cost. Magnesium sulfate is not efficient to prolong gestation and presents significant side-effects. Cyclooxygenase inhibitors also present significant side-effects. Up till now, there is not enough evidence to recommend the use of nitric oxid donors to inhibit preterm delivery. There is no basis for the use of antibiotics to avoid prematurity in face of preterm labor.
