Bull's hemostasis after castration
China's traditional castration bull has a long history, a variety of methods, and different effects. Its purpose is to make the bull lose its fertility, change the bull's performance, and improve the quality of livestock products. The castration bull's surgery seeks to be safe, fast, and less irritating, to ensure rapid postoperative recovery and effectively curb the occurrence of postoperative complications. However, in clinical practice, spermatic hemorrhage, spermatic cord inflammation, and spermatic cord spasm occur frequently, often resulting in secondary surgery and re-medication, which has negative impact on animal husbandry production. The author applied bovine self-sheathed ligament anti-barbed spermatic cords instead of sutures and castrated bulls in local townships in 131 cases. The postoperative complications were few and the effect was good. Two cases of operation methods and experiences were reported as follows. Peer provides reference and reference. 1 Operation Technology This method is only applicable to blood castration, and the instruments used are not changed. In order to facilitate the operation, Baoding bulls are often taken on the left side. According to the requirements of conventional surgery, the equipment and the surgical department are disinfected. The operator holds the bull's scrotum with his left hand and cuts the scrotum out of his right hand with a knife to squeeze out the testis. The native sheath is separated by hand and the testis is gently pulled to expose the spermatic cord. Separate the sheath ligament from the spermatic cord to the tail of the epididymis, cut it, and then continue to separate the sheath ligament along the spermatic cord to the finer part of the spermatic cord, grasp it with the left hand and cooperate with the right hand to wrap the sheath ligament around the spermatic cord. Knuckle, continue to hit the trotters knot 2 to 3 in the direction of the testicles, confirm the ligation firmly, cut off the spermatic cord at the last knot, remove the testis, and smear iodine in the broken end. 2 Precautions First check the body condition of the bull and the operation department. If you have cryptorchidism, palsy, inflammation, etc., you should not use this method. Care must be taken to protect the ligament of the sheath when peeling the intrinsic sheath to avoid peeling together. Separation of sheath ligament on the spermatic cord should be light and complete protection, such as the use of this method should not be used. The first trotter knot during ligation should not be too tight, otherwise tissue damage will result in postoperative bleeding. 3 typical examples Example 1 Hemou's cattle needed to be castrated. The author worked with the local animal husbandry and veterinary station personnel. The method is as follows: The cow has no abnormality in the whole body and partial examination and can perform surgery. On the left side of Baoding bull, after cleaning the scrotum and surrounding dirt with clean water, disinfect the scrotum and surrounding skin with 0.1% potassium permanganate solution. The surgeon's hands and arms are first washed with soapy water, then disinfected with 0.1% benzalkonium bromide, and immersed in the hands and arms for 3 to 5 minutes before being dried. The operator holds the scrotum with his left hand, holding the testicles close to the scrotum's bottom wall, holding the knife in his right hand, making an incision at the bottom of the scrotum parallel to the scrotum gap (the length of the incision is about 3/4 of the length of the testis's longitudinal axis), once with the intrinsic sheath cut. Wear, homeopathic testicular expulsion, isolated the intrinsic sheath and testicles by hand, gently pull the testicles to expose the spermatic cord, separate the sheath ligament, and cut at the tail of the epididymis. Continue to separate the sheath membrane along the spermatic cord to the more detailed part. Hold the fistula with your left hand and tie the sheath ligament around the spermatic cord with your right hand, and continue to beat two trotter knots in the direction of the testicle. Tighten gently to confirm that the ligature is secure. The spermatic cord was cut at the last knot, the testis was removed, and iodine was applied to the broken end. In the same way, remove the other testis. Finally wipe the incision with 5% iodine and around the scrotal skin and apply an appropriate amount of anti-fly cream. After a 10-day visit, the incision healed without any other abnormalities. Example 2 Zhang's 6-year-old ox using a sheath ligament against barbed spermatotomy, right scrotal incision bleeding, has not yet naturally stop bleeding every 4 hours, so once again lying Baoding bull, with potassium permanganate solution Rinsing the scrotum and scrotal blood clots, due to swelling around the scrotal incision, inconvenient to find the spermatic cord, check the ligation is not off and bleeding, determine the hemorrhage is not on the spermatic cord. With gauze slowly extending along the spermatic cord, for hemostasis, intramuscular injection of 5% Anrou blood 20ml, exit the gauze. The incision healed well after 10 days. 4 Summary and Experience This method is applied in clinical 131 cases, safe, convenient, effective, local materials, eliminating the need for sutures, while reducing postoperative complications. With sutures, some can cause foreign body allergies, inflammatory reactions, affecting the health of the carcass.
