EMBRYOTOMY. 8^ 



thorax, Immediately above the sternum ; rupture the 

 structures in passing Into the cavity ; tear away the 

 iirst pair of ribs, to allow free passage of the hand; 

 remove the lungs and heart ; puncture the diaphragm, 

 and remove the abdominal organs through the'opening. 



BiOtation. 



Sometimes it is necessary to bring about rotation of 

 the foetus, which means a partial turning of it to right 

 or left. If either the fore or hind limbs are out of the 

 passage, this is not so difficult of accomplishment, by 

 cording the presented extremities, and applying traction 

 in the direction the fcetus is desired to take. 



If all the limbs are in the uterus, it is much more 

 difficult. Cord one pair, pass in the hand, and try to 

 elevate the body of the foetus, while traction on the 

 cords is applied as directed. Failing In this, a sack 

 or blanket, passed under the abdomen of the mother, 

 and pressure applied, may bring about rotation. 



Version. 



It Is sometimes necessary to cause version of the 

 fcetus. This means converting a posterior into an 

 anterior presentation, and vice versa. In this case, 

 cord the limbs that are wanted into the passage, and, 

 with a repeller,push the opposite extremity downwards 

 and forwards Into a horn of the uterus, at the same 

 time applying traction to the cords. Sometimes great 

 benefit Is derived by elevating the body of the foetus 

 with the hand, or by raising or lowering the hind- 

 quarters of the parent ; the treatment depending uppn 

 the case.
