PRE SENT A TIONS OF THE FCETC/S.

Doo" asleep. In this we have two distinct positions, according as the 

 fcetus lies on one side or the other. But it may also assume a third and 

 almost vertical position — the croup on the floor of the abdomen of the 

 mother, and the creature in the attitude of a Dog sitting. 



The important consideration m these three positions is related to the 

 situation or direction of the head ; as if this is known, we may easily 

 infer that of the other parts of its body, and thus appreciate the indica- 

 tions for delivery to be followed in this pathological presentation. Ac- 

 cording to the direction of the head, the three following positions are 

 described ; — 



I. Right Cephalo-ilial Position. — The fcetus is on its right side, which 

 rests more or less directly on the abdominal walls of the mother, the 

 head in the right flank, the croup towards the left flank, the body more 

 or less curved, and the dorso-lumbar region towards the pelvis, in which 

 it presents (Fig. 60).

 Right Cephalo-ilial Position of the Foetus. 



2. Left Cephalo-ilial Position. — This is the reverse of the preceding. 



3. Cephalo-sacral Position. — In this position the foetus is presented by 

 [the back, and in an almost vertical attitude : the croup resting on the 

 [floor of the mother's abdomen, the head more or less depressed, and 

 [directed forward towards the sacro-lumbar region — the creature being 

 ^seated, as it were, on the udder of its parent (Fig. 61). 



D. Sterno-Abdominal Presentation. — In this presentation the foe- 

 [tus offers the abdomen to the inlet of the pelvis, and on exploration the 

 mand first meets this part, and two or more of the limbs, but always at 

 lleast a hind and fore one. The head may be found, or it may be out of 

 Freach. The sternum and other parts on the lower surface of the body 

 ^can also be felt. 



In this presentation there are two principal positions : — 

 I. Left Cephalo-ilial Position. — The foetus lies on the right side, th6 

 [head towards the left ilium of the mother, and the croup to the right 

 milium (Fig 62).
