Un ultrasonido es una forma segura e indolora de ver el interior del cuerpo. Con este método, tú y el médico pueden ver una imagen del útero y del feto.

¿Qué es un ultrasonido?

Un ultrasonido, también conocido como ecografía, le permite al médico ver si el feto se está desarrollando con normalidad. El médico podría recomendarte que te hagas 1 o más ultrasonidos en diferentes momentos del embarazo. Puede utilizarse para verificar que no haya anomalías ni problemas en la anatomía del feto.

Según cuán avanzado esté tu embarazo, las imágenes de ultrasonido le permiten al médico hacer lo siguiente:

  • Calcular la fecha de parto.
  • Ver la posición de la placenta.
  • Conocer el tamaño, la posición, el movimiento, la respiración y el ritmo cardíaco del feto.
  • Ver la cantidad de líquido amniótico en el útero.
  • Detectar embarazos múltiples (gemelos, trillizos, etc.).

Los ultrasonidos también pueden utilizarse para identificar ciertas anomalías congénitas, como el síndrome de Down.

¿Cómo funciona un ultrasonido?

Para los ultrasonidos se utilizan ondas sonoras de alta frecuencia que generan imágenes del feto y de los órganos reproductivos (como el útero y el cuello uterino). Existen dos maneras de hacer un ultrasonido durante el embarazo: a través de la piel del abdomen (vientre) o a través del interior de la vagina.

Durante un ultrasonido abdominal, el médico coloca un poco de gel en el estómago y pasa el emisor de ultrasonido por la piel. El gel está frío y puede que sientas algo de presión, pero no duele.

Durante un ultrasonido vaginal, el médico inserta el emisor de ultrasonido en la vagina. Se siente como un examen vaginal normal que podrías tener durante un control ginecológico. Tal vez sientas un poco de presión, pero no duele.

Médicos, enfermeros o técnicos especializados realizan los ultrasonidos y leen los resultados.

¿Cuánto cuesta un ultrasonido?

El costo de un ultrasonido depende del tipo de ultrasonido y dónde te lo hagas. Muchos planes de seguros de salud cubren el costo de los ultrasonidos durante el embarazo, pero consulta con la compañía aseguradora para saber con certeza.

Puedes visitar el centro de salud de Planned Parenthood local para recibir ultrasonidos en forma gratuita o a bajo costo, ya sea que tengas seguro de salud o no. Tu médico también podría ayudarte a encontrar lugares donde hagan ultrasonidos asequibles en tu zona.

Ultrasonido: Sonograma o Ecografía

Un sonograma es un procedimiento que utiliza ondas sonoras de alta frecuencia para escanear la cavidad del abdomen y la pelvis de una mujer, creaciendo una imagen (sonograma) de la bebé y la placenta . Las palabras de ultrasonido y sonograma son técnicamente diferentes, pero se utilizan indistintamente y hacen referencia al mismo examen.

¿Qué tipos de ultrasonidos hay?

Básicamente, hay siete exámenes de ultrasonido diferentes, pero el proceso es el mismo.
Los distintos tipos de procedimientos incluyen:

Ultrasonido Transvaginal – Los transductores de sonda especialmente diseñados son usados dentro de la vagina para generar imágenes de la ultrasonografía. Es usado más frecuente durante las primeras etapas del embarazo.
Ultrasonido Tradicional – El ultrasonido tradicional utiliza un transductor sobre el abdomen para generar imágenes 2-D del feto.
Ultrasonido Avanzada – Este examen es similar a el ultrasonido tradicional, pero el examen apunta a un problema sospechado y usa equipo más sofisticado.
Ultrasonido Doppler – Este procedimiento imagenológico mide cambios leves en la frecuencia de las ondas del ultrasonido como rebotan del movimiento de objetos, como células de la sangre.
Ultrasonido 3-D – Utiliza sondas especialmente diseñadas y software para generar imágenes en 3D del feto.
Ultrasonido 4-D o 3-D Dynamico – Uses specially designed scanners to look at the face and movements of the baby prior to delivery.
Ecocardiografía Fetal – Uses ultrasound waves to assess the baby’s heart anatomy and function. This is used to help assess suspected congenital heart defects.

How is an ultrasound performed?

The traditional ultrasound procedure involves placing gel on your abdomen to work as a conductor for the sound waves. Your healthcare provider uses a transducer to produce sound waves into the uterus. The sound waves bounce off bones and tissue returning back to the transducer to generate black and white images of the fetus.

When are ultrasounds performed?

Ultrasounds may be performed at any point during pregnancy, and the results are seen immediately on a monitor during the procedure. Transvaginal scans may be used early in pregnancy to diagnose potential ectopic or molar pregnancies.
There is not a recommended number of ultrasounds that should be performed during routine prenatal care. Because ultrasound should only be used when medically indicated, many healthy pregnancies will not require ultrasound. The average number of ultrasounds varies with each healthcare provider.
Additional ultrasounds might be ordered separately if your healthcare provider suspects a complication or problem related to your pregnancy.

What does the ultrasound look for?

Ultrasounds are diagnostic procedures that detect or aid in the detection of abnormalities and conditions related to pregnancy. Ultrasounds are usually combined with other tests, such as triple tests, amniocentesis, or chorionic villus sampling, to validate a diagnosis.
An ultrasound exam is medically indicated throughout pregnancy for the following reasons:
First Trimester:

  • Confirm viable pregnancy
  • Confirm heartbeat
  • Measure the crown-rump length or gestational age
  • Confirm molar or ectopic pregnancies
  • Assess abnormal gestation

Second Trimester:

  • Diagnose fetal malformation
    • Weeks 13-14 for characteristics of potential Down syndrome
    • Weeks 18-20 for congenital malformations
  • Structural abnormalities
  • Confirm multiples pregnancy
  • Verify dates and growth
  • Confirm intrauterine death
  • Identify hydramnios or oligohydramnios – excessive or reduced levels of amniotic fluid
  • Evaluation of fetal well-being

Third Trimester:

  • Identify placental location
  • Confirm intrauterine death
  • Observe fetal presentation
  • Observe fetal movements
  • Identify uterine and pelvic abnormalities of the mother

What are the risks and side effects to the mother or baby?

The ultrasound is a noninvasive procedure which, when used properly, has not demonstrated fetal harm. The long term effects of repeated ultrasound exposures on the fetus are not fully known. It is recommended that ultrasound only be used if medically indicated.

Answers to common questions related to an ultrasound/ sonogram exam:

If an ultrasound is done at 6 to 7 weeks and a heartbeat is not detected, does that mean there is a problem?

No, it does not mean there is a problem. The heartbeat may not be detected for reasons that include: tipped uterus, larger abdomen, or inaccurate dating with last menstrual period. Heartbeats are best detected with transvaginal ultrasounds early in pregnancy.
Concern typically develops if there is no fetal heart activity in an embryo with a crown-rump length greater than 5mm. If you receive an ultrasound exam after week 6, your healthcare provider will begin to be concerned, if there is no gestational sac.

How accurate are ultrasounds in calculating gestational age?

Your healthcare provider will use hormone levels in your blood, the date of your last menstrual period and, in some cases, results from an ultrasound to generate an estimated gestational age. However, variations in each woman’s cycle and each pregnancy may hinder the accuracy of the gestational age calculation.
If your healthcare provider uses an ultrasound to get an estimated delivery date to base the timing of your prenatal care, the original estimated gestational age will not be changed.

Why do some healthcare providers schedule ultrasounds differently?

If there are any questions regarding gestational age, placenta location, or possible complications then more ultrasounds may be scheduled. Because ultrasound should only be used when medically indicated, many healthy pregnancies will not require ultrasound. The average number of ultrasounds varies with each healthcare provider.

How accurate are ultrasounds in determining the conception date to determine paternity?

Your healthcare provider will use hormone levels in your blood, the date of your last menstrual period and, in some cases, results from an ultrasound to generate an expected date of conception. However, many differences in each woman’s cycle may hinder the accuracy of the conception date calculation.
The viability of sperm varies as well, which means intercourse three to five days prior to ovulation may result in conception. Ultrasound dating of conception is not reliable for determining paternity because the ultrasound can be off by at least 5-7 days in early pregnancy.

When can an ultrasound determine the sex of the baby?

You may have an ultrasound between 18 to 20 weeks to evaluate dates, a multiples pregnancy, placenta location or complications. It may also be possible to determine the gender of your baby during this ultrasound. Several factors, such as the stage of pregnancy and position of fetus, will influence the accuracy of the gender prediction.
To be 100% sure you will have an anxious wait until the birth!

Are ultrasounds a necessary part of prenatal care?

Ultrasounds are only necessary if there is a medical concern. As noted above, ultrasounds enable your healthcare provider to evaluate the baby’s well being as well as diagnose potential problems. For women with an uncomplicated pregnancy, an ultrasound is not a necessary part of prenatal care.

Ultrasound for infants at 1 month in the Primorsky district of St. Petersburg

The first screening of a child is recommended at the age of 1 month. Using the ultrasound method, the brain, heart, kidneys, abdominal cavity, and hip joints are examined. These are the main investigated organs, but diagnostics can also be carried out on soft tissues, the thyroid gland, organs of the reproductive system and other systems. Not only the shape of the organs, size, but also the blood flow, the presence and volume of fluids are examined. Ultrasound examination is harmless and painless, therefore it can be performed even for newborns.

Why at 1 month?

It is during the period of 1 month that many pathologies and diseases can be detected that can be effectively treated and corrected if detected in a timely manner. Parents with a child are consulted after ultrasound by a pediatrician, neurologist, surgeon, orthopedist.

An ultrasound examination of a 1-month-old baby is recommended by the Ministry of Health, but parents can choose not to do so if they wish. Some types of research will not be available in the future. For example, brain studies using ultrasound through a non-overgrown fontanel are possible only in children from birth to 1 month. The joints are clearly visible, because the bones are not yet strong, and ultrasound passes through them.

Preparing for an ultrasound scan of a child at 1 month

Preparation at 1 month for an ultrasound examination is not required, it will not be necessary to torture the child with starvation. Fasting is recommended only for children after reaching 5 years of age, when examining the abdominal organs.

A child at the age of 1 month can take his favorite toys for the procedure so that he is distracted by them and is calm. If the child is breast-fed before the procedure, this will also relax him.

Indications for ultrasound of a child at 1 month

Ultrasound of the brain:

  • prematurity;
  • traumatic injuries;
  • suspicion of malformations;
  • ischemia;
  • neurological symptoms;
  • suspicion of an inflammatory process.

Examination is also carried out for preventive purposes, to identify possible pathologies. It is especially important to conduct an ultrasound of the brain in a timely manner with frequent regurgitation or disproportionate growth of the child’s head, excessive excitability or lethargy.

Ultrasound of the abdominal cavity:

  • inconsistency in the laboratory analysis of urine blood;
  • bloating, liver enlargement;
  • loose stools, yellowing of the skin;
  • discomfort, the baby cries, does not want to eat.

Ultrasound of the hip joints:

  • possible genetic inheritance;
  • infectious diseases affecting the joints;
  • multiple pregnancy in the mother;
  • one leg is shorter than the other;
  • clicking or other sounds when abducting the leg;
  • asymmetric pleats on the buttocks.

ultrasound of the heart:

  • suspicion of pathology;
  • blue nasolabial triangle;
  • low weight for no reason;
  • low body temperature of unknown etiology;
  • heredity.

Ultrasound is an informative diagnostic method that does not harm children of any age. Therefore, it is recommended to carry out it at the age of exactly one month, not only according to indications, but also for the purpose of screening and prevention. Most modern parents are worried about their children and undergo ultrasound at 1 month in a timely manner. The procedure does not take much time, about 30-40 minutes.

Ultrasound of a newborn at 1 month. Where to get an ultrasound scan for a newborn child

To make sure that the child is absolutely healthy and does not require special treatment, examinations help, among which an important place is occupied by ultrasound. Several types of such procedures are practiced: ultrasound of the brain, hip joints, heart and pelvic organs. The need for them is determined by experts. If the baby was born before the due date, he will definitely need neurosonography.
If the baby has a suspected heart disease, an ultrasound of the heart of a newborn baby can help in the diagnosis — sometimes it is done in maternity hospitals. Our specialists can also perform this procedure.

Quite often, babies are also prescribed neurosonography (that is, a study of the brain), which must be carried out before the closure of the fontanel. This may be an ultrasound of a newborn; at 1 month — during this period, echogenicity is high enough to get a complete picture.
Also at the age of 1 month, babies can undergo ultrasound of the hip joints of newborns, which helps in the diagnosis of dysplasia (congenital dislocations) of the joints.
