Hodge ‘s blueprints are terminology physicians use in the obstetric branch to be able to finalize themselves before attending a delivery. You’ve probably never heard of it, but they handle it as a fundamental part of a physical exam in Obstreticia.
Its main function is to determine what the position of the fetus will be in the birth canal path and thus establish how the degree of descent can be when the baby has to go outside through the vagina.
What is Hodge’s Plan?
Hodge’s Plane is a level that is used in the gynecology part to imaginarily divide the pelvis from the narrow upper to the narrow bottom, in order to locate what the location of the fetus will be in your birth canal and what the dimensions of your head will be so it can pass through the birth canal until it is expelled. Lee Plans are also used to be able to do the same type of study, exploration, and calculation.
What is the function of this procedure?
The Hodge Plan should be applied knowing well the anatomy that comforts the area of the woman’s pelvis. This area is a place delimited by bones that are located under the trunk and containing the internal reproductive organs.
With the Hodge Plan four imaginary and parallel lines will be drawn from several specific points where the zone will be divided into four parts, hence these zones are contrasted to calculate the level of descent and degree of the Fetal fitting.
Leopold’s maneuvers will measure this degree of fitting and will be complemented by a vaginal touch, which will determine the type of pelvis. You can also distinguish the 4 Hodge Plans that we wrote later.
Through all these examinations, the doctor can know if the delivery is advanced normally or if, on the contrary, the delivery is not going to develop easily since its measures are not consistent for a good expulsion of the fetus.
The 4 plans of Hodge
There are four Hogde plans that will be studied and evaluated to determine various circumstances.
Primary Plano de Hodge
It is an imaginary line that crosses from the upper edge of the Pubis Synfinis to the junction of the fifth lumbar vertebra or the back of the Sacral bone. This part is called as the anatomical shape with the upper strait of the pelvis.
In this plane it can be stated whether the head is properly positioned or fitted into such a zone. This maneuver can be completed with Leopold’s Third Maneuver, where a manual scan called a rustling will be done to find out how the lower fetal pole embedded in the pelvis is located.
It is another parallel and imaginary line formed with respect to the Foreground. It is formed from the lower edge of the public synfinis to the second vertebra of the sacral bone. At this point we can specify that the fetal head is in the background or is hinted or fixed. Here you can now practice Leopold’s Third Maneuver to determine what his position is.
Third Plan of Hodge
It is the imaginary and parallel line that happens to the other two previous planes. It is traced from both sciatic spines, crossing the anterior face of the 3rd Sacra vertebra to the Ischion. In this plane it can be stated if the head of the fetus is correctly fitted, from this point we can determine that the baby will be close to birth and we can talk about Active Phase.
Hodge’s Room Plan
This fourth line is the one that is represented from the back of the vertex of the Sacral Bone and corresponds to the narrow lower part of the pelvis. Here there should be a fetal head fully fitted in this area and it will be confirmed that a birth is already near.
At this point, the fetal head can be perceived without problems by means of a manual scan. This will give way to the days following a Dilation and Borramiet although the membranes may still be intact and domed, which must break for the birth to occur.
