Gestational sac – Refer to appropriate standard table. Crown-rump length for dating. Long axis of uterus. Abnormal structures in adnexa. ENDOVAGINAL EXAM: Usage as follows unless otherwise directed or indicated. A fetal pole with uncertainty of viability. Gestational sac with no fetal pole identified during abdominal exam.

Dating Criteria for delivery: determines whether lungs are considered mature for delivery. FHT documented 30 weeks by Doppler. 36 weeks since UPT positive. US of CRL at 6-11 weeks makes gestational age >39 weeks. US of under 20 weeks supports gestational age >39 weeks. STAGES OF LABOR. First: beginning of contractions to complete cervical dilation

First trimester dating should be determined by CRL not from mean gestational sac diameter as the latter is less accurate. Estimated date of delivery (EDD) and gestational age from known in vitro fertilisation (IVF) dates should not be changed.

Since the introduction of diagnostic ultrasound, more reliable approaches to the dating of pregnancies have developed. These include gestational sac diameter and volume and crown rump length measurement in the first trimester. Crown rump length measurement has been described to predict gestational age accurately to with in ± 4.7 days.

Routine measurements including mean gestational sac diameter (MSD) and embryo crown rump length (CRL) were taken at each visit (17). Participants were subsequently seen at the time of their routine dating scan (11 to 14 weeks gestation) and anomaly scan (18 to 22 weeks gestation) and underwent an additional ultrasound assessment of fetal growth ...

Pregnancy dating using mean sac diameter (MSD; average of X/Y/Z measurements) is only useful at 5-6 weeks. Once the fetus has reached 13wks gestational age, BPD (biparietal diameter), HC (head circumference), AC (abdominal circumference), and FL (femur length) are used. Gestational age determination by CRL is accurate to within 5-7 days

Definitive diagnosis can be made if products of conception (gestational sac and villi) are seen by the provider, or if a previously seen pregnancy is no longer visible by ultrasound. While a fetal heartbeat can sometimes be seen as early as 2 mm crown rump length (CRL), an early pregnancy loss cannot be definitively diagnosed until the CRL is ...
