Furosemide treatment in pregnancy reduced cardiac output and stroke volume while increasing total peripheral resistance. However, it did not significantly lower blood pressure or cause vasoconstriction.

Area of Science:

  • Cardiovascular physiology
  • Pharmacology in pregnancy

Background:

  • Pregnancy is characterized by a hyperdynamic circulatory state.
  • Understanding the impact of medications on maternal hemodynamics is crucial.

Purpose of the Study:

  • To evaluate the pharmacodynamic effects of furosemide on maternal cardiovascular parameters during pregnancy.

Main Methods:

  • Twenty-one pregnant women received 20 mg of furosemide daily.
  • Cardiac output (CO), stroke volume (SV), and total peripheral resistance (TPR) were measured using Doppler technique before and after treatment.

Main Results:

  • Furosemide administration led to a decrease in CO and SV, and an increase in TPR.
  • These hemodynamic changes did not normalize to typical pregnancy values.

Conclusions:

  • Furosemide effectively modulated the hyperdynamic circulation of pregnancy.
  • The drug did not result in clinically significant hypotension or vasoconstriction.
