The diagnostic criteria of DKA are-

glucose

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.

There are no firm criteria for initiating red cell transfusion. The decision to provide blood transfusion should be based on both clinical and haematological assessment.

The 2009–12 Confidential Enquiries into Maternal Deaths and Morbidity report3 highlighted the importance
of correlating clinical signs and symptoms expected from different blood loss values to help target decisions on resuscitation, and also emphasised the importance of taking the woman’s weight into account.

The therapeutic target in case of massive blood loss is to maintain Haemoglobin  greater than 8 gm/dL.

• 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.

Where delivery is planned, either by elective caesarean section or induction of labour, LMWH maintenance therapy should be discontinued 24 hours prior to planned delivery.

Regional anaesthetic or analgesic techniques should not be undertaken until at least 24 hours
after the last dose of therapeutic LMWH.
LMWH should not be given for 4 hours after the use of spinal anaesthesia or after the epidural catheter has been removed, and the epidural catheter should not be removed within 12 hours of the most recent injection.

Regarding 'Prophylactic dose'-Regional techniques should be avoided if possible until at least 12 hours after the previous
prophylactic dose of LMWH.
LMWH should not be given for 4 hours after use of spinal anaesthesia or after the epidural catheter has been removed and the catheter should not be removed within 12 hours of the most recent injection.

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.
