Why might outlet forceps be necessary for the delivery of a primigravida with a large fetus?

Using outlet forceps during delivery is often indicated when the fetal head is visible at the perineal floor. This situation typically means that the fetus is in the final stages of the delivery, requiring assistance to help facilitate a safe and efficient birth. The use of outlet forceps can be crucial when time is of the essence, as they can help minimize the duration of the second stage of labor, particularly in cases involving a primigravida (a woman who is experiencing her first pregnancy) and a large fetus, where additional support might be necessary to prevent complications.

When the fetal head is visible, the healthcare provider can position the forceps effectively to assist the delivery without disrupting the physiological process too much. This means that any potential risks associated with prolonged labor or fetal distress can be alleviated.

In other contexts, such as if the fetal head is engaged past the inlet or at a certain station (like +1), it may not necessarily warrant the usage of outlet forceps, as these situations typically indicate that the fetus is appropriately positioned for descent without the need for further mechanical assistance. Similarly, if the head has reached the ischial spines, it indicates that the fetus is engaged but not necessarily ready for delivery, so assistance might be
