The postoperative reaction of the buried line varies from person to person, some are normal reaction and do not need any treatment, while some are caused by individual allergy or improper postoperative care resulting in infection, which should be dealt with in time. Normal reaction 1, normal reaction: due to the stimulation of injury and goat intestinal cord (heterogeneous protein) stimulation, in 1-5 days, the localization can appear red, swollen, painful, hot and other aseptic inflammatory reaction. In a few cases, the reaction is heavier, and there is a small amount of exudate at the incision, which is also a normal phenomenon and generally does not need treatment. If more exudate protrudes from the skin surface, milky white exudate can be squeezed out, wiped away with 70% alcohol cotton balls, covered with sterilized gauze. The local temperature of the affected limb will also increase after the operation, which can last for 3-7 days. A small number of patients may have a systemic reaction, that is, 1—3 days after the buried line body temperature rises, usually about 38 degrees, local infection phenomenon, continued for 2-4 days after the body temperature returns to normal. The total number of white blood cells and neutrophil polymorphonuclear cell count can be increased after burying the thread, and should be observed. 2, there are very few patients, the needle eye out of the liquid, and even the line out, this is a good phenomenon, with the fire pot continuous pulling out the liquid, a chronic disease may be removed from the root. Abnormal reaction 1, a small number of patients due to the treatment of aseptic operation is not strict or wound protection is not good, resulting in infection. Generally, 3-4 days after treatment, local redness, swelling, pain intensification, and may be accompanied by fever. Local hot compresses and anti-infection treatment should be given. 2. Individual patients are allergic to sheep’s intestines, after treatment, local redness, swelling, itching, fever and other reactions, and even fat liquefaction at the incision, sheep’s intestines overflow, should be appropriate for anti-allergy treatment. 3. Nerve damage, such as sensory nerve damage, there will be nerve distribution area skin sensory impairment, there will be the innervation of the muscle group paralysis, such as damage to the sciatic nerve, peroneal nerve, will cause foot ptosis and bunions can not be dorsiflexed. If such phenomenon occurs, the goat’s intestines should be withdrawn in time and given appropriate treatment. In order to avoid these unnecessary losses, we need to operate strictly, scientific operation, absolutely not sloppy and careless.
