Give the method of delivering an anterior presentation (dorsosacral 

 position) with the fore limbs retained. 

 Repel foetus upward and backward, pass a cord around the 

 radius, slide it down toward the carpus, correct the deviation and 

 complete the delivery. If the head has passed beyond the vulva, 

 decapitation may be advantageous before attempting repulsion. 

 In some cases amputation of one limb and evisceration may be neces- 

 sary to reduce the size of the foetus and facilitate delivery. 



Give a method of delivery of the cephalosacral position of the foetus. 



In this position, the foetus sits on the floor of the abdomen, the 

 head directed forward and the withers toward the sacrolumbar 

 region of the mother. That is, it sits up like a dog. By most authori- 

 ties, this position is considered impossible because of its unstability. 

 To effect delivery, version must be accomplished. The dorsal pre- 

 sentation must be changed to an anterior or posterior. Version may 

 be effected by intra-uterine injections of emollients such as flax- 

 seed or slippery elm infusions. If this method fails, evisceration 

 and detruncation of the foetus is the only course to follow. 



Describe a method of delivering a right cephalo-ilial position, dorso- 

 lumbar presentation. 

 The dystocia from this position is practically the same as in the 

 cephalosacral position and the method of procedure is the same. 

 (See answer to preceding question.) 



Describe the sterno-abdominal position of the foetus. 



This is more accurately termed "ventral transverse presenta- 

 tion. ' ' The foetus presents with all of the feet in, or near, the pelvic 

 inlet and the head retained. It lies upon its side, transverse to the 

 long axis of the body of the mother with the head resting in the 

 flank in the region of one or the other of the maternal ilia. Hence 

 there are two possible positions, right cephalo-ilial and left cephalo- 

 ilial. 



Describe Cesarean section in the mare and name some of the compli- 

 cations that may arise in connection with this operation. 



Cesarean section refers to the delivery of a foetus by means of 

 an incision through the abdominal and uterine walls. The mare 

 should be placed under general anesthesia. Her forelegs should 

 be drawn forward and the hind legs backward and securely fastened. 

 The field of operation being thoroughly cleansed and disinfected, 

 make an incision in the flank through the skin and muscles, extend- 

 ing from the level of the external angle of the ilium downward about
