IN CASES OF UNCERTAINTY (EQUIVOCAL NITRAZINE, FERNING, AND POOLING), WHICH OF THE FOLLOWING DYES SHOULD NOT BE INJECTED TRANSABDOMINALLY FOR THE DIAGNOSIS OF PRETERM PROM

• A. Indigo carmine
• B. Methylene blue ✓
• C. Evans blue
• D. Fluorescein

In cases of uncertainty regarding the diagnosis of preterm premature rupture of membranes (PROM), it is important to exercise caution when considering transabdominal injection of dyes for diagnostic purposes. Among the dyes listed, methylene blue should not be injected transabdominally for the diagnosis of preterm PROM. Methylene blue is known to have potential adverse effects, especially when introduced into the amniotic cavity. It can cross the placental barrier and may lead to fetal toxicity or harm.

Methylene blue is a synthetic dye commonly used in various medical procedures, but its use in pregnant women, particularly for diagnostic purposes related to pregnancy complications like PROM, is not recommended due to its potential risks. Therefore, in cases where there is uncertainty in diagnosing preterm PROM and considering transabdominal injection of dyes, methylene blue should be avoided.

It is essential to consult with healthcare professionals and obstetricians when faced with diagnostic uncertainties in pregnancy-related conditions like PROM. The safety of both the mother and the fetus should always be a top priority when considering any diagnostic procedures involving potentially harmful substances.
