Artificial rupture of membranes
Artificial rupture of membranes
Artificial rupture of membranes (ARM), also known as amniotomy or amniotic sac rupture, is a procedure used in obstetric practice to induce or accelerate labor. The pronunciation is /ɑːrˈtɪfɪʃəl 'rʌptʃər ɒv 'mɛmbreɪnz/.
Etymology
The term "artificial rupture of membranes" is derived from the Latin "artificium" meaning "craftsmanship, craft, or art", and the Latin "ruptura" meaning "a breaking". The term "membrane" comes from the Latin "membrana" which means "skin, parchment, membrane".
Procedure
The procedure involves the deliberate breaking of the amniotic sac by a healthcare professional, usually an obstetrician or midwife, to release the amniotic fluid. This is typically done using a thin plastic hook known as an amnihook or a similar instrument.
Indications
ARM is usually performed when labor is not progressing naturally or when there is a need to speed up labor for medical reasons. It may also be used in conjunction with other methods of labor induction such as oxytocin administration.
Risks and Complications
While ARM is generally considered safe, it can lead to complications such as infection, umbilical cord prolapse, and changes in the baby's heart rate. It may also increase the risk of caesarean section.
