Committee Opinion No. 723. American College of Obstetricians and Gynecologists What Is A Third Trimester Ultrasound Scan? It is an ultrasound scan carried out in the third trimester of pregnancy (weeks 28 to 40). Generally most women are only offered 2 scans, one in the first trimester and another called an anatomy scan in the second trimester (although you may be offered an additional scan at week 12 called a nuchal scan).A third trimester scan may be advised where. 2nd and 3rd.

Particularly late in pregnancy, this may not be a comfortable position for the patient, who can experience symptoms from inferior vena cava compression by the heavy, gravid uterus. Women in this position should be watched carefully for. OB 2nd and 3rd Trimester. Second and Third TRIMESTERS: Second Trimester- 12- 28 weeks. Third Trimester- 28- 40 weeks. OB Ultrasound Indications: age, growth, vaginal bleeding, fetal presentation, fetal number, size & dates, pelvic mass, follow up, recognizing normal fetal anatomy, checking for malformation. Fetal positions This chapter discusses the use of emergency ultrasound to evaluate pregnant patients in the second and third trimesters. During this time period, the major indications for its use are the initial assessment of the pregnant trauma patient, evaluation of vaginal bleeding and preterm labor, and evaluation of abdominal pain

The indications for the ultrasound examinations differed as did the gestational age at delivery (P<.01; Table 2). The total number of antepartum complications after randomization was similar in the two groups with approximately one in four low-risk women developing a complication in their third trimester of pregnancy In 1996, ACNM published the first clinical bulletin providing guidelines for midwives who expressed an interest in incorporating third trimester ultrasound examinations into their clinical practice. The document was retired in 2009 yet clinical practice has changed in that many midwives are now adding all trimesters of ultrasound examination.

ISUOG has published guidance on the use of Doppler ultrasound at the 11 to 13 + 6-week fetal ultrasound examination 1.

The baby should have a renal sonogram (at least a week after birth, to allow for rehydration) During the third trimester of pregnancy the fetal ultrasound scan is performed with the help of the abdominal sensor within pregnancy weeks 34-36. At this stage of pregnancy the fetus has all vital organs fully developed and the period of fast growth and maturity continues. At this stage the fetus weighs 2400-2600 g and its length is 44-46 cm 24 weeks or greater (unless request by ordering physician) A. AC is <10% even when it's an isolated finding. B. If the EFW <10 th. C. If requested by ordering Physician. NO umbilical Doppler needed if there is low amniotic fluid. 3 PW Doppler samples of the umbilical artery are taken at the middle (free loop) section of the umbilical cord. Background: Diagnostic ultrasound is used selectively in late pregnancy where there are specific clinical indications. However, the value of routine late pregnancy ultrasound screening in unselected populations is controversial. The rationale for such screening would be the detection of clinical conditions which place the fetus or mother at high risk, which would not necessarily have been. Redating a pregnancy may occur when there is a discrepancy between the estimated due date (EDD) calculated by the last menstrual period (LMP) and that by ultrasound. Care should be taken when redating a pregnancy, especially in the third trimester, as there may be other reasons for a fetus to be small for gestational age (e.g. intrauterine growth restriction)

An obstetrical ultrasound in the second or third trimester includes an evaluation of fetal number, cardiac activity, presentation, amniotic fluid volume, placental position, fetal biometry, and an anatomic survey. The maternal cervix and adnexa should be examined. Clinical UM Guidelines, which address medical efficacy, should be considered. A limited second- or third-trimester ultrasound examination includes an evaluation of fetal number, cardiac activity, presentation, placental location with respect to the internal cervical os, and amniotic fluid volume. If requested, a limited obstetric ultrasound examination may include fetal biometry 3D ultrasound with transabdominal scanning in and after the late first-trimester with conventional 2D Ultrasound Scan, a general impression of fetal posture can be obtained, but it cannot be described precisely.

Specific clinical indications for examination other than the two screening scans listed above require an appropriate clinical code. Unless clinically determined, growth scans in the third trimester are not usually required. Any ultrasound scan that a woman is referred for should clearly note the appropriate clinical code and clinical indication There is no indication for an ultrasound examination in the first trimester of pregnancy unless there is a clinical abnormality. Why is a scan not recommended at the mother's first visit?
