Ultrasound uses reflected sound waves to obtain images of the unborn baby and pelvic organs. It is a very safe and painless.
Empty bladder 90 mins prior to appointment, drink 750ml of water over the next 60 mins and hold.
What happens during the procedure
You may be asked to put on a gown. Gel is applied to the skin to improve contact between the skin and transducer (a handheld plastic probe which sends and receives the reflected sound waves that forms the image). The transducer is moved slowly over the abdomen to acquire images of the baby and pelvic organs in different planes. The images are displayed on a computer monitor for interpretation. Ultrasound is painless but discomfort from transducer pressure may be experienced if your bladder is full.
You may be asked permission to perform an internal (transvaginal) examination if a more detailed examination of the cervix is required. You will be asked to wear a gown after emptying your bladder and undressing from the waist down. A sheet will cover your lower abdomen. A sterilised and covered transducer coated with gel is placed carefully into the vagina where it lies closer to the cervix.
How long does it take?
An ultrasound takes approx 15-60 minutes depending on the complexity.
