Knowledge point
Obstetric Ultrasound is the use of ultrasound scans in pregnancy
Obstetric ultrasound can be used to:
1. Date the pregnancy and estimate the expected date of confinement (EDC)
- this is valuable when the last menstrual period is not sure or inaccurate
- this can be achieved by measuring the size of the fetus
2. Viability
- when a pregnant woman has abdominal pain or vaginal bleeding, fetal viability is a concern
- fetal heart beat can be seen
3. Determine location of fetus
- to see the pregnancy is located in the right place (inside uterus) or abnormal place (outside uterus or called ectopic pregnancy)
4. Check the location of the placenta in relation to the cervix
- a low-lying placenta can cause vaginal bleeding
Cleaning the Needle Guide
a) Remove the needle guide from the transducer after each use. Use a small, soft brush to remove visible contaminants from the surface. Keep parts from drying out until complete cleaning can be accomplished.
b) Soak the needle guide for at least five minutes in a neutral pH, low foaming enzymatic detergent. While immersed, use instrument brush to remove trapped contaminants from surfaces and features. If visible contaminants are not easy to remove, repeat the soaking procedure for another five minutes. Remove the needle guide from cleaning solution and remove any remaining residue with dry wipe. Observe cleaning solution manufacturer’s directions for use and recommendations for concentration.
