After collection, swabs should be placed in a non-nutrient transport medium, such as Amies or Stuart. Specimens should be transported and processed as soon as possible. If processing is delayed, specimens should be refrigerated. When testing for GBS, the lab should be specifically informed that the swab is for GBS testing.

• The timing of delivery should be tailored to the patient.
• If history of vaginal bleeding/ other risk factors for preterm delivery- consider ‘Late preterm delivery’- 34+0 to 36 +6 weeks.
• If uncomplicated placenta previa- Consider between 36+ 0 and 37+0.

Systemic chemotherapy is contraindicated in the first trimester because of a high rate of fetal
abnormality,but is safe from the second trimester.

Caesarean section is the recommended mode of delivery in cases of cord prolapse when vaginal birth is not imminent in order to prevent hypoxic acidosis.
Category 2 caesarean birth can be considered for women in whom the fetal heart rate pattern is normal, but continuous assessment of the fetal heart trace is essential.

In case of cord prolapse in advanced labor , delivery should be expedited.

This is GBS bacteruria. GBS bacteriuria is associated with a higher risk of chorioamnionitis and neonatal disease. Women with GBS bacteriuria should be offered IAP.

Women with GBS urinary tract infection (growth of greater than 10^5 cfu/ml) during pregnancy should receive appropriate treatment at the time of diagnosis as well as IAP. 

Successful VBAC is more likely among women with previous caesarean for
fetal malpresentation (84%) compared with women with previous caesarean for either labour dystocia (64%) or fetal distress (73%) indications.

Women are generally advised to wait for at least 2 years after treatment for breast cancer before
conception.

- For pregnancies at more than 16 weeks of gestation the term low-lying placenta should be used when the placental edge is less than 20 mm from the internal os on transabdominal or transvaginal scanning (TVS).

If the distance between the internal os and the placental edge is 20 mm or more on TVS, the placental location should be recorded as normal and managed as per routine

• The term placenta praevia should be used when the placenta lies directly over the internal os.

• Anthracyline regimens are safe
• There are fewer data on taxanes, which should be reserved for high-risk (node-positive) or metastatic disease.
• Tamoxifen is not used until after delivery.
• Trastuzumab  is contraindicated during pregnancy.
• Haemopoietic growth factors (granulocyte colony stimulating factor) may be employed to ameliorate chemotherapy-induced neutropenia.

It is not necessary to administer anti-D Ig to D negative females without childbearing potential, or males who receive D positive platelets.

Routine ultrasound screening is not useful. Selective ultrasound screening can be considered for women with breech presentation at term who are considering vaginal birth.

Risk of anal sphincter injury in women undergoing VBAC is 5%.

Birthweight is the strongest predictor of anal sphincter injury in women undergoing VBAC.

If the placenta is thought to be low lying (less than 20 mm from the internal os) or praevia
(covering the os) at the routine fetal anomaly scan, a follow-up ultrasound examination
including a TVS is recommended at 32 weeks of gestation to diagnose persistent low-lying
placenta and/or placenta praevia.

Use of TVS- to accurately see the placental edge. Also, cervical length is a predictor of antepartum bleeding and emergency preterm caesarean section in placenta praevia. Women with a cervical length of less than 31 mm have a 16 times higher risk of emergency
caesarean section due to massive haemorrhage.
