This blogpost is a compilation of random facts about peripartum mental health which is one of an important aspect of women care. As a health care provider it is pertinent to provide optimum care for the mental health of the woman. Mental health disorders are prevalent and a woman is vulnerable during pregnancy and in the post part period. According to MBRRACE Suicide is now considered a direct cause of maternal death.
This post should be used as an adjunct to your study material for this topic as only random facts are given here.
I hope this is helpful for you all.
Thanks

Few facts about the commonly used medicines

- Toxicity → if >1.2 mmol/l — most common ECG finding T-wave flattening
- Using lithium women should give birth in the hospital
- Should be withheld during labour and child birth due to high placental transfer
- Levels checked again 12 hrs post delivery before being reinstated
- Not advised in breast feeding
Sodium valproate
