RESUMO
Resumen Las anomalías del cordón umbilical están asociadas a efectos adversos durante el embarazo. El nudo verdadero del cordón umbilical está presente en el 0.3-2.1% de los embarazos y se ha asociado a muerte fetal. Dentro de los factores de riesgo se incluye, la edad materna, índice de masa corporal (IMC) elevado, multiparidad, trastornos hipertensivos, tabaquismo, polihidramnios, diabetes gestacional, sexo masculino del feto y otras malformaciones. El diagnóstico prenatal del nudo verdadero es raro y un desafío. La mayoría se diagnostica durante el nacimiento y sólo el 0.08% de los nudos verdaderos son diagnosticados de manera prenatal. El registro cardiotocográfico puede registrar trazos no tranquilizadores que reflejan que hay un estrés hipóxico o mecánico que interrumpe la oxigenación fetal. El objetivo de este reporte es mostrar un caso de nudo verdadero del cordón umbilical que presentó taquicardia fetal persistente durante el trabajo de parto con terminación del embarazo vía vaginal.
Abstract Umbilical cord abnormalities are associated with adverse effects during pregnancy. The true umbilical cord knot is present in 0.3-2.1% of pregnancies and has been associated with fetal death. Risk factors include maternal age, high BMI, multiparity, hypertensive disorders, smoking, polyhydramnios, gestational diabetes, male sex of the fetus, and other malformations. Prenatal diagnosis of the true knot is rare and challenging. Most are diagnosed at birth and only 0.08% of true knots are diagnosed prenatally. Non-reassuring cardiotocography traces may be present, reflecting hypoxic or mechanical stress disrupting fetal oxygenation. The aim of this case report is to present a case of true umbilical cord knot presenting with persistent fetal tachycardia during labor, resolved by vaginal delivery.
RESUMO
Pregnancy is an important time period during reproductive cycle of every woman. WHO has set about certain guidelines, in the care of pregnant ladies it’s called as Antenatal care The main aim of this care is to provide an uneventful antenatal period and there by producing a healthy offspring. Intrapartum period also plays a major role in determining the health status of both mother and fetus. Most of the discomforts in the mother can be directly visualized as well as interrupted from her vitals. But in the case of fetus the intrauterine discomforts can be interrupted only from assessing the fetal heart rate. When the fetal heart rate rises above 160/min it is called as fetal tachycardia. This rise in FHR can affect both mother as well as the fetus. The cause should be identified as early as possible and prompt management should be provided. Yoga provides physical as well as mental wellbeing through a holistic approach. It comprises of Pranayama and Asanas which can bring positive effect on the health status of the pregnant woman as well as results in the good outcome of labor. The main reason for tachycardia here was maternal anxiety and stress. Intranatal yoga works very efficiently here and thereby corrects the fetal tachycardia
RESUMO
OBJECTIVE：To investigate the ro le of clinical pharmacists in the therapy of fetal tachycardia by oral administration of digoxin through mother. METHODS ：The clinical pharmacists participated in the whole process of drug therapy for a pregnant woman with fetal tachycardia. According to 31+6 weeks of gestation ，the fetal heart rate of 230 beats/min at admission，clinical pharmacists provided the suggestion for the doctor about the safety and blood concentration determination of digoxin in the treatment of fetal tachycardia by mother. The patient ’s blood potassium value was lower than the normal range ，and it was suggested that potassium should be supplemented before digoxin was used ，and the initial dose of digoxin was 0.5 mg per 12 h. On the 7th day in the hospital ，the dosage of digoxin should be adjusted to maintaining dose （0.25 mg per 12 h）；on the 11th day in the hospital ，the patient ’s blood sodium value was low ，and the clinical pharmacists gave diet guidance. At the same time ， the clinical pharmacists explained the adverse reactions of digoxin to the doctors ，nurses and patients ，and closely observed and educated the patients. RESULTS ：Doctors adopted the suggestions of the clinical pharmacists. The fetal heart rate decreased to 180 beats/min from hospital after 13 days of treatment. The maternal digoxin concentration remained stable. No adverse drug reactions occurred in the mother and infant. CONCLUSIONS ：Maternal and child safety should be taken into account in the medication of pregnant patients. The clinical pharmacists assisting doctors to formulate medication strategying ，and carrying out pharmaceutical care for patients ，can ensure the effectiveness and safety of medication for fetal tachycardia.
RESUMO
Las frecuencias anormalmente rápidas sobre un corazón con una estructura menos distensible, rodeado por una coraza que sólo le permite defenderse con la frecuencia cardiaca para sostener el gasto cardiaco, hacen que este sea un corazón con márgenes estrechos de tolerancia frente a las taquiarritmias. Las frecuencias persistentes y superiores a 220 latidos por minuto, generan presiones anormalmente altas sobre todo el corazón y el sistema venoso. Hidrops y edema placentario son secuelas finales antes de la muerte fetal, y aún hasta este punto se pueden controlar y revertir. Aunque en teoría cualquier tipo de arritmias común en la vida extrauterina se podría desencadenar en el feto, 90% de éstas están incluidas en la taquicardia supraventricular reciprocante y en el flutter. Ambos tipos de arritmias pueden responder a la digoxina, aunque algunas son refractarias a este medicamento. La aplicación de ultrasonido sobre el corazón, permite no sólo descartar anomalías cardiacas asociadas, sino realizar protocolos de tratamiento. La medición de la relación de los tiempos ventrículo atrial:atrio ventricular, permite considerar otro tipo de arritmias como la taquicardia ectópica de la unión y la forma permanente reciprocante de la unión, etc., e incluir otros anti-arrítmicos, como amiodarona, flecainida, sotalol, entre otros. La principal vía de uso de los anti-arrítmicos es la transplacentaria. Por lo tanto, no sólo el feto se expone a posibles efectos secundarios, sino también la madre. Un grupo multidisciplinario enfrentará esta situación con el fin de ofrecer el mejor resultado para los dos.
A heart with a not much distensible structure, surrounded by a membrane, and only able to react with the heart rate for maintaining its cardiac output, has a narrow margin of tolerance in front of tachyarrhythmias. Persistent heart rates >200/min generate abnormally high pressure on the heart and the venous system. Hydrops and placental edema are common final outcomes before fetal death, that still at this point can be controlled and reverted. Although theoretically any type of arrhythmias could be developed in the fetus, 90% of fetal tachyarrhythmias correspond to supraventricular reciprocant tachycardia and flutter. Both types of arrhythmias may respond to digoxin, although some are refractory to this drug. Ultrasound application to the heart allows not only to rule out associated heart anomalies, but to realize treatment protocols. The measurement of the relation between ventricular-atrial and atrio-ventricular times allows to consider another type of arrhythmias such as junctional ectopic tachycardia, permanent junctional reprocicant tachycardia, etc., and to include other antiarrhythmics such as amiodarone, flecainide and sotalol among others. The main administration route of antiarrhythmics is the transplacental. Therefore not only the fetus but also the mother is exposed to drug side effects. A multidisciplinary group will confront this situation in order to offer both mother and fetus the best result.
