Five measures for newborn lamb care

1. Ensure the lamb starts breathing smoothly right after birth. Immediately wipe the mouth, nose, and ears with a dry cloth to clear any mucus. If the amniotic sac is still intact, carefully tear it open to help the lamb breathe more easily. This step is crucial to prevent suffocation and promote immediate respiration. 2. In cases of stillbirth or apparent lack of breathing, quick action is essential. Hold the lamb by its hind legs and gently pat its chest or back to expel any amniotic fluid from the airway. Place the lamb on a slightly elevated surface with its head lower than its body to encourage airflow. Begin artificial respiration immediately. You can also use cotton balls dipped in iodine or alcohol to stimulate the lamb’s nostrils, which may trigger breathing. 3. Dry the lamb quickly to maintain body temperature and help the ewe bond with her newborn. Allow the ewe to lick and dry the lamb naturally. If she shows no interest, sprinkle some bran or straw around the lamb to encourage her to clean it. This not only helps keep the lamb warm but also strengthens the maternal bond, stimulates oxytocin release, and aids in the expulsion of the placenta. 4. Handle the umbilical cord properly to prevent infection. Most lambs will naturally rupture the umbilical cord, but if not, gently pull it from the abdomen 5–10 cm away from the body, squeezing the blood back into the lamb before cutting. Then, apply heat (like a hot iron) to cauterize the end and disinfect it with 5% iodine to prevent bacterial infections. 5. Ensure the lamb receives colostrum as soon as possible. After the ewe has given birth, trim the long hair around her udder to make nursing easier. Clean the teats with warm water or a mild potassium permanganate solution, and express the first few drops of milk to remove any impurities. Once the ewe is stable, assist the lamb to nurse. Colostrum provides vital nutrients and antibodies that boost the lamb’s immune system and reduce the risk of illness.

Trauma Cannulated Screw

Cannulated screw is a common internal fixation device in orthopedic surgery.

Working process

During the operation, the Kirschner wire with the hole matching the hollow screw is first drilled into the bone of the fracture site, and then the hollow screw is screwed into the fracture site through the guidance of the Kirschner wire. Finally, the Kirschner wire is pulled out to complete the fixation of the fracture site. In many cases of fracture of the neck and femur, the healing cycle is long, and it usually takes about 30 months to remove the cannulated screws. At this point, the bone and the surface of the cannulated nail are closely connected and firmly connected in the nail path, which leads to defects easily generated by conventional nail removal methods, causing secondary injury at the fracture healing site and causing pain to the patient. Percutaneous cannulated screw internal fixation for femoral neck fractures has the advantages of small trauma, good healing, low rate of femoral head necrosis, and good stability.
