Espresso: Treatment of Acute Hypertension in Pregnancy and Postpartum
/Our second espresso episode focuses on the acute treatment of severe-range BPs in the pregnant and postpartum patient. More or less, we let the freshly released ACOG CO 767 speak for itself.
Below you’ll find the algorithms we describe in the podcast, which are present in ACOG CO 767. In addition to the below, always remember:
-Obtain IV access and labs (CBC, Creatinine, AST, ALT, urine protein:creatinine ratio) for any newly diagnosed patient with severe-range pressures.
-Avoid labetalol in patients with known asthma, as the beta-blockade effect can trigger respiratory issues, as well as those with CHF or pre-existing cardiac disease. Labetalol may also cause neonatal bradycardia due to beta-blockade.
-Immediate-release nifedipine should not be administered sublingually due to possibility of developing precipitous hypotension. Similarly, parenteral hydralazine may also cause precipitous maternal hypotension.
-IV magnesium sulfate should be given at a 4g or 6g bolus initially, followed by 2g/hr drip for the prevention of eclamptic seizures, if not previously given. Adjusted dosing may be required if renal insufficiency is noted on laboratories. Magnesium sulfate is not an antihypertensive agent.
