Name of the Procedure:

Ultrasound of the pregnant uterus, real time with image documentation; fetal and maternal evaluation after the first trimester (≥ 14 weeks 0 days), transabdominal approach; single or first gestation.

Summary

An ultrasound is a safe, non-invasive imaging technique used to monitor the health of both the fetus and the pregnant mother. After 14 weeks of pregnancy, this procedure involves using a transabdominal ultrasound to obtain real-time images for evaluating fetal development and maternal uterine conditions.

Purpose

The ultrasound aims to monitor the growth and development of the fetus, assess the health and position of the placenta, check the volume of amniotic fluid, and evaluate the overall health of the pregnant uterus. It provides vital information that helps in ensuring a healthy pregnancy and early detection of any potential complications.

Indications

• Routine prenatal screening after the first trimester
• Monitoring fetal growth and development
• Assessing the position and function of the placenta
• Checking amniotic fluid levels and uterine conditions
• Investigating any symptoms like bleeding, pain, or abnormal fetal movement patterns
• Confirming or adjusting the estimated due date

Preparation

• The patient may be advised to drink water and have a full bladder prior to the exam to improve image quality.
• Loose, comfortable clothing is recommended.
• No fasting or special medications are typically required.
• Previous ultrasound reports and medical history should be available for review.

Procedure Description

1. The patient lies on an examination table.
2. A special conductive gel is applied to the abdomen area to ensure good contact between the skin and the ultrasound transducer.
3. The transducer, a handheld device, is moved over the abdomen.
4. Real-time images are generated and displayed on a screen, capturing fetal and uterine details.
5. The sonographer documents the findings, which may include fetal measurements, heart activity, movement, placental position, and amniotic fluid levels.

6. The procedure is painless and does not require anesthesia or sedation.

   Duration

   The procedure typically takes about 20-30 minutes.

Setting

• Outpatient clinic
• Hospital radiology department
• Specialized ultrasound center

Personnel

• Trained sonographer or ultrasound technician
• Radiologist or obstetrician who interprets the results

Risks and Complications

• Ultrasound is generally considered very safe.
• Rarely, slight discomfort from the pressure of the transducer on a full bladder.

Benefits

• Provides crucial information about fetal health and development.
• Non-invasive and safe for both mother and fetus.
• Immediate and real-time results.

Recovery

• No recovery time needed.
• Patients can resume normal activities immediately after the procedure.

Alternatives

• Doppler ultrasound for more detailed blood flow analysis.
• MRI in rare cases requiring comprehensive anatomical detail.
• Each alternative has its own set of advantages and limitations.

Patient Experience

• The procedure is usually painless, though there may be slight discomfort due to the gel's coolness and the pressure from the transducer.
• Real-time imagery can be fascinating and reassuring for expecting parents.
