Brief summary

The primary purpose of this study is to demonstrate the safety of the use of non steroidal medication in women who have high blood pressure (hypertension) in pregnancy. Traditionally the use of non steroidal medication has been avoided due to theoretical concerns of exacerbating preexisting hypertension. The hypothesis is that there is no increase in events of severe hypertension that would occur in the postpartum population and actually it is an effective pain killer and avoids the need for stronger pain killers like endone.

Interventions

Use of non steroid anti inflammatory drug (ibuprofen) for pain relief following caesarean section in women who have hypertensive disorders of pregnancy (chronic hypertension, preeclampsia, gestational hypertension). a) Treatment arm Women in the treatment arm will receive paracetamol (1 g four times orally per day) and ibuprofen (400 mg three times orally per day) regularly. If additional analgesia is required due to increased pain requirements, women will receive opioids as required (prefer

Use of non steroid anti inflammatory drug (ibuprofen) for pain relief following caesarean section in women who have hypertensive disorders of pregnancy (chronic hypertension, preeclampsia, gestational hypertension). a) Treatment arm Women in the treatment arm will receive paracetamol (1 g four times orally per day) and ibuprofen (400 mg three times orally per day) regularly. If additional analgesia is required due to increased pain requirements, women will receive opioids as required (preferably endone orally 5-10 mg or as determined by their treating physicians). On the other hand, if women are not experiencing pain, ibuprofen will be administered as required. The medications will be administered by a midwife. Both groups will receive treatment for 7 days duration or up to time of discharge. Analgesic requirements will depend upon the needs of the participant, and cumulative non steroidal anti inflammatory drug (NSAID) and opioid doses will be recorded for analysis.
