Its 5 IU by slow intravenous injection.

In women with suspected PE who also have symptoms and signs of DVT, compression duplex ultrasound should be performed. If compression ultrasonography confirms the presence of DVT, no further investigation is necessary and treatment for VTE should continue.

Pregnant women with suspected PE who have symptoms and signs of DVT should have bilateral compression duplex ultrasound leg studies performed. A diagnosis of DVT may indirectly confirm a diagnosis of PE and since anticoagulant therapy is the same for both conditions, further investigation may not be necessary.

This would limit the radiation doses given to the mother and her fetus.

Obstetric patients who are postoperative and receiving unfractionated heparin should have platelet count monitoring performed every  2 to3  days from days 4 to 14 or until heparin is stopped.

The platelet count should be checked after 24 hours of initiating treatment if the patient has previously received heparin (unfractionated or LMWH) in the last 100 days.

Previous vaginal delivery, particularly previous VBAC, is the single best predictor of successful VBAC and is associated with a planned VBAC success rate of 85–90%.

Previous vaginal delivery is also independently associated
with a reduced risk of uterine rupture.

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

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

Conversion from LMWH back to warfarin should be delayed for at least 5 to 7 days after delivery
to minimise the risk of haemorrhage during the period of overlap of LMWH and warfarin treatment.

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.
