Abstract
Objective
The aim of this review is to evaluate the relationship between the use of non-steroidal anti-inflammatory drugs (NSAIDs) during last trimesters of the pregnancy and the reduction of amniotic fluid.
Methods
Electronic databases were searched (PubMed, Medline, and Scopus). Selection criteria included studies reporting the relationship between oligohydramnios and use of NSAID during pregnancy. We analyzed the median age of women, weeks of pregnancy at the beginning of the drug administration, kind of medication, period of exposure and dosage, deepest vertical pocket (DVP), and amniotic fluid index (AFI).
Results
Of the 68 records identified, we analyzed 29 studies investigating the administration of NSAIDs, including 11 studies examined the administration of the Indomethacin, four articles have focused on the use of Nimesulide, and only two manuscripts considered the use of Diclofenac. We found a strict correlation between the development of oligohydramnios and the use of NSAIDs. The oligohydramnios is reversible, and the normal amount of amniotic fluid is restored after the interruption of the treatment.
Conclusions
The use of NSAIDs should be considered when maternal benefits outweigh the potential fetal risk, at the lowest effective dose for shortest duration. Beyond 48 h of NSAIDs treatment, we consider ultrasound monitoring of amniotic fluid, and we suggest stopping therapy if a decline AFI is present.
