Do not use pad tests in the routine assessment of women with urinary
incontinence.

Up to 10% of women scheduled for ERCS go into labour before
39+0 weeks. Therefore it is good practice to to discuss and document a plan for delivery if labour starts prior to the scheduled date.

• 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.

The use of postoperative laxatives is recommended to reduce the risk of wound dehiscence.
Bulking agents should not be given routinely with laxatives.

Use of stool softeners such as lactulose is recommended for about 10 days after the repair.

A systematic review reported that women with one, two, or three or more previous caesarean deliveries experience a 1%, 1.7% or 2.8% risk of placenta previa in a subsequent pregnancy. ( Source- Birth After Previous
Caesarean Birth Green-top Guideline No. 45 ).

Assisted reproductive technology ( RR- 3.71, OR 2.67)and maternal smoking ( OR 1.42)  increase the risk of placenta praevia.

After undertaking a detailed clinical history and examination, perform
