In this 162nd episode I welcome Dr. Henao back to the show to discuss hypertensive disorders of pregnancy and how to manage them.
- During our discussion of treatment of eclamptic seizures Dr. Henao said benzos were first line treatment. This is assuming the patient is already getting magnesium. For test questions, the answer for first line treatment should be Mg. In reality, patients will likely get both at the same time.
- Serum Mg concentrations can be reported as mmol/L, meq/L or mg/dL. The important ranges to know for testing (though in reality different people may get symptoms at different times) are a therapeutic range of 2-3.5 mmol/L or 4-7 mEq/L or 5-9 mg/dL; A loss of patellar reflexes at >3.5, >7, >9; Respiratory paralysis at >5, >10, >12 and cardiac arrest at >12.5, >25, >30. EKG changes including prolonged PR and widened QRS happen in much the same range as loss of patellar reflexes, maybe a bit before but there is a lot of overlap.

In this 159th episode I welcome Dr. Juanita Henao to the show to discuss prevention and management of postpartum hemorrhage.
One CORRECTION: At about minute 4:30 Dr. Henao states that in women with PPH the mortality rate is 10% but what she meant to say is that PPH accounts for 10% of maternal deaths in the United States.
