Most labors progress normally over the course of several hours. But some do not, and in this and several other situations, artificial rupture of membranes is sometimes advised.

Begin by examining the patient.

It is best if the head is fully engaged. While lesser degrees of engagement are sometimes acceptable, it is important to avoid creating a prolapsed umbilical cord.

An amnihook is used to rupture the membranes. The hook is guided into place with your index finger.

The bag of waters is snagged with the hook, and torn open.

Artificial rupture of membranes should be painless.

After rupture, observed the amniotic fluid for quantity, color, and odor.

This amniotic fluid is slightly meconium stained, and average in quantity. It has no foul odor.
