Genotyping can be undertaken from 16 weeks of
gestation for all except K which can be undertaken from 20 weeks, due to the risk of a false negative
result if performed earlier in pregnancy.

After undertaking a detailed clinical history and examination, perform
multichannel filling and voiding cystometry before surgery for stress urinary
incontinence in women who have anterior or apical prolapse.

Before surgery- an MDT should review the proposed treatment. And before surgery, women should be asked for consent for their data to be entered in a national registry.

Use of UFH predisposes patients to thrombocytopenia..

Obstetric patients who are postoperative and receiving unfractionated heparin should have platelet count monitoring performed from days 4 to 14 ,

or until heparin is stopped.

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

• If pharmacological measures fail to control the haemorrhage, surgical interventions should be initiated sooner rather than later.
• Intrauterine balloon tamponade is an appropriate first-line ‘surgical’ intervention for most women where uterine atony is the only or main cause of haemorrhage.

ABG Analysis is of limited value in diagnosis of PE.

In one study- ABG analysis showed that only 10% had arterial P O2 levels less than 60 mmHg and 2.9% had oxygen saturation levels less than 90%.

• Measure post-void residual volume by bladder scan or catheterisation in women with symptoms suggestive of voiding dysfunction or recurrent UTI.
• Use a bladder scan in preference to catheterisation on the grounds ofacceptability and lower incidence of adverse events.
• Undertake a urine dipstick test in all women presenting with urinary incontinence.
• Undertake routine digital assessment to confirm pelvic floor muscle contraction before the use of supervised pelvic floor muscle training for the treatment of urinary incontinence.

Do not use the Q-tip, Bonney, Marshall and Fluid-Bridge tests in the assessment of women with urinary incontinence.
