ABSTRACT
AIMS:
Addressing volume expansion may improve the management of hypertension across the pregnancy continuum. We conducted a systematic review to summarize the evidence on the use of loop diuretics in the context of hypertensive disorders during pregnancy and the postpartum period. METHODS ANDRESULTS:
Medline, Embase, Cochrane library, ClinicalTrials.gov, and Google Scholar were searched for original research articles published up to 29 June 2021. Of the 2801 results screened, 15 studies were included eight randomized controlled trials, six before-after studies, and one cohort study. Based on random effects meta-analysis of before-after studies, antepartum use of loop diuretics was associated with lower DBP [mean difference -17.73âmmHg, (95% confidence intervals -34.50 to -0.96); I2â=â94%] and lower cardiac output [mean difference -0.75âl/min, (-1.11 to -0.39); I2â=â0%], with no difference in SBP, mean arterial pressure, heart rate, or total peripheral resistance. Meta-analysis of randomized controlled trials revealed that postpartum use of loop diuretics was associated with decreased need for additional antihypertensive patients [relative risk 0.69, (0.50-0.97); I2â=â14%], and an increased duration of hospitalization [mean difference 8.80âh, (4.46-13.14); I2â=â83%], with no difference in the need for antihypertensive therapy at hospital discharge, or persistent postpartum hypertension.CONCLUSION:
Antepartum use of loop diuretics lowered DBP and cardiac output, while their postpartum use reduced the need for additional antihypertensive medications. There was insufficient evidence to suggest a clear benefit. Future studies focusing on women with hypertensive pregnancy disorders who may most likely benefit from loop diuretics are required.
