Vasectomy of ram and postoperative treatment and nursing

The ligation of the ram is the ligation or removal of the vas deferens (preferably one), and makes the ram have a good sexual desire for testing after the operation. A total of 205 cases of ligation were performed from 1997 to 2006, with a success rate of 100%. The operation methods and matters needing attention are summarized as follows.

1 preparation before operation

1.1 for the selection of rams, healthy rams aged between 2 and 4 years old with bright male characteristics must be selected as surgical objects.

1.2 preparation and disinfection of surgical instruments and establishment of surgical procedures, including 3 hemostatic forceps, scissors, scalpels and blades, suture needles and sutures, 15min was soaked in 5% Lysol solution before operation, and then sterilized with alcohol cotton balls.

1.3 the preparation of surgical drugs is as follows. Debridement and disinfectant: sterilized saline, 5% Lysol, 5% iodine, 75% alcohol. Application of medicine on the wound: anti-inflammatory powder. Application of antibiotics: penicillin, streptomycin and so on. Hemostasis and anesthetics: hemostat, procaine hydrochloride. Other supplies: cotton wool, sterilized gauze.

2Surgical methods

2.1The determination of Baoding and operative part of ram: 6 hours before operation, the ram was fasted by water and fasting, and the ram was recumbent on the side, and the upper hind limb was transposed forward to Baoding, so as to fully expose the surgical part, and the operation site determined the range of 1cm above and below the midpoint of the scrotal neck in front of the scrotum.

2.2 Surgical hair shearing disinfection: shearing the surgical site, washing and disinfecting with 5% Lysol solution, then smearing 5% iodine, 4-5min and deiodizing with 75% alcohol cotton balls.

2.3Anesthesia: 0.5% procaine hydrochloride 1Oml was injected subcutaneously around the operation, and the operation could be performed after 5min.

Cut the skin: cut the skin longitudinally along the vas deferens, keep the incision within 2cm, use hemostatic forceps to separate the subcutaneous tissue, cut the sheath, fully stop the bleeding, hook one side of the scrotal neck to the incision with the index finger of the right hand, gently cut open the upper mucosa of the vas deferens with a scalpel after finding the vas deferens, clip the vas deferens with hemostatic forceps and pull it to the incision, and cut off a section of about 1-1.5cm. Then cut off the vas deferens on the other side in the same way.

2.5 incision suture: check whether there is bleeding before suture, if there is bleeding, stop bleeding in time, then wash the wound thoroughly with normal saline and seal the sheath sac. Sprinkle a little anti-inflammatory powder evenly into the incision, then suture the skin with one shot, and finally wipe the incision and surrounding skin with 5% iodine for thorough disinfection.

3The management of critical illness during operation.

The common crisis of ligation surgery is to cut the blood vessels, leading to bleeding, at this time to timely tie the ruptured blood vessels, fully stop bleeding, and to clean the blood clots in the scrotum, and then wash them with normal saline.

4 treatment and nursing after operation

Postoperative management is very important to the success of the operation. Attention should be paid to the following points:

4.1 pay attention to feeding management: sheep after operation pay special attention to feeding management, giving nutritious and digestible feed and adequate drinking water, while paying attention to warmth and enclosure hygiene.

4.2 cleaning and disinfection of the wound: as the ram is prone to lying in pain after operation, the wound is easy to be contaminated, so it should be cleaned and disinfected in time. If bleeding is found, stop bleeding and clean the accumulated blood in the scrotum in time, and then thoroughly wash with normal saline and wipe with iodine wine for disinfection.

4.3 treatment: in addition to the application of systemic antibiotics, hemostasis and analgesia should also be carried out, but the principle of few but fine drugs should be adopted. Appropriate amount of penicillin, streptomycin and antongding should be injected intramuscularly twice a day for 4 days, while 0.5 g of hemostat was injected intramuscularly twice a day for 2 days. Individual patients with wound infection and systemic reaction should be treated symptomatically.

5 Summary

As long as the male sheep ligation operation pays attention to the following aspects, it will certainly ensure the success of the operation: first, the thorough disinfection of surgical instruments and supplies, the operation department; second, gentle action, beware of vascular rupture, if vascular rupture should be dealt with in time, fully stop bleeding, clear the accumulation of blood and clean it; third, careful nursing and treatment after operation.
