Retrograde Oviductal Flush (Laparotomy Approach) Technique

Оглавление

Performed under general anesthesia.

 The mare is fasted for 24 hours prior to surgery.

 Antibiotics and flunixin meglumine (1.1 mg/kg, IV, s.i.d.) are administered prior to surgery and after surgery as needed.

 The mare is placed under general anesthesia and in dorsal recumbency.

 The ventral abdomen is clipped free of hair.

 A standard surgical prep is made over the ventral abdomen.

 Two paramedian incisions are made in the caudal ventral abdomen through the skin and blunt dissection is used to pass through the external and internal abdominal oblique muscles.

 A hand is passed into the abdomen and the adjacent ovary and uterine horn tip are exteriorized.

 A small incision is made near the uterine horn tip and the uterus is everted to expose the papilla of the UTJ.

 The papilla is cannulated with the blunt‐ended catheter.

 The oviduct is flushed retrograde with sterile saline containing fluorescein dye.

 The infundibulum end of the oviduct is observed for the presence of colored saline which may contain masses.

 The procedures are repeated on the contralateral oviduct.

 The uterus and abdomen are closed in a routine manner.
