In order to maintain the need for limb fracture repositioning, deformity correction, and fixation of the body position required for clinical treatment, plaster fixation is an effective treatment modality. So what are the complications, care points and precautions for pediatric plaster fixation? After plaster fixation, as with external fixation of small splints, not everything is fine. If you do not pay attention, one or another complications may still occur. Generally, the common complications are as follows: 1, pressure sores: the plaster is very hard after drying, although there is a layer of cotton inside, but the protruding parts of the bones are still very sudden pressure phenomenon. If the pressure is too long the skin will ulcerate and form an ulcer soup. Patients should pay attention to the line of pressure sores if they feel persistent pain in certain parts within the cast. 2, compression nerve palsy: the cast is too tight may also compress the surrounding nerve tissue, resulting in compression nerve palsy. If the calf cast compresses the fibular head, it may cause peroneal nerve paralysis. The forearm cast compresses the radial nerve, easily causing radial nerve palsy and wrist joint prolapse. Therefore, after fixation, if you find numbness of the limb, finger and toe movement impairment, pain, it may be the early symptoms of compression nerve injury. 3, limb ischemic contracture: there is no loose space in the plaster fixation cavity, if the plaster bandage is too tight, or the limb swelling is serious, it will lead to osteo-fascial compartment syndrome, resulting in limb ischemic muscle contracture or limb necrosis. This complication is very serious, so it should not be taken lightly. 4.Plaster syndrome: It refers to the acute gastric dilatation that occurs after the plaster of the trunk (plaster undershirt, thoracic-humeral plaster, hip herringbone plaster and frog plaster, etc.), which is one of the serious complications of plaster fixation. It is very rare in children. How to care for the patient with external plaster fixation? 1. Explain to the patient the basic principle of plaster fixation to obtain the patient’s cooperation, plaster fixation because of the gradual sensitization of the plaster and release of heat, which is the patient will have a burning sensation, generally will not burn the skin. However, thereafter it will feel wet and cold because of the plaster water, these are normal phenomena and will not have any effect on the child. Patients and family members should be relieved of their doubts, and do not move the limb at will after fixation, so as not to affect the effect of fixation. 2.Prepare to clean the skin of the affected area before plastering. It takes some time to fix the cast, and it cannot be opened casually after fixation, so the skin should be cleared and cleaned with soap and water before, and the dirt of the skin should be wiped off, which can be disinfected with alcohol and wrapped with sterile treatment wipes, and the traumatic area should be changed to prevent infection, which is more comfortable after fixation. 3, pay close attention to the blood circulation of the limb to prevent ischemic necrosis of the fat body tissue. After plaster wrapping, it is preferred to elevate the affected limb to help blood circulation and decongestion. Therefore, the blood circulation at the end of the limb should be observed at all times within 24 hours. If the following conditions occur: pale or blue skin, pain, significant swelling, numbness or decrease in skin temperature, etc., it indicates over tightness as well as poor blood flow, and the doctor needs to be notified immediately for timely treatment or hospital consultation. If the ischemia is prolonged, it may cause local necrosis of the limb. When the skin is itchy, use some alcohol drops, never use bamboo needles, chopsticks and other hard objects to poke into the plaster to prevent poking the skin and then cause infection. Observe whether there is any abnormal smell inside the plaster, if there is rotten from the smell, it indicates that the wound is infected or the skin inside the plaster forms pressure sores causing tissue necrosis. Please consult a doctor for treatment as soon as possible. 4.Observe whether there is bleeding in the outside of the cast. After surgery, the affected limb is wrapped in plaster, so pay attention to observe the wound bleeding. If there is blood seepage from the wound, the blood will penetrate to the surface of the cast. If He determines whether the bleeding continues, use a pencil to draw a line along the edge of the blood stain and indicate the time. If the blood stain continues to expand, it means the bleeding does not stop and should be treated by a doctor in time. What should I pay attention to after external fixation of plaster? After external fixation of plaster, daily care is very important, it is related to the success or failure of treatment. The following points should be noted: 1. Elevate the affected limb to facilitate the return of venous blood and lymphatic fluid to reduce the swelling of the limb. Usually, the upper limb should be suspended in front of the chest and the lower limb should be padded with pillows to elevate the affected limb. 2.After external fixation of the fracture cast, appropriate functional exercises should be carried out to facilitate the healing of the fracture. For example, the upper limb should do wrist extension and flexion activities; the lower limb should do quadriceps contraction, ankle dorsiflexion, toe extension and so on. 3.After external fixation of the plaster, the edges should be trimmed and opened in time to prevent decubitus ulcers from occurring in the axilla, waist and skeleton due to compression, and trunk and abdominal plaster trimmed and opened can prevent cardiopulmonary complications to facilitate breathing and digestion. 4.After the external fixation of the limb cast, it is necessary to help the patient turn over regularly to prevent decubitus ulcers, keep the cast dry, do not get water, and do not be soaked with feces and urine. Pay attention to keep warm in winter to prevent frostbite. 5. Pay attention to whether there is any sign of infection in the incision of the affected limb, and check frequently whether there is any enlargement and pressure pain in the lymph nodes in the axilla and groin. If there is any of the above, it means that there is a possibility of infection in the fracture wound, and you should go to the hospital for examination and treatment in time. 6.When lying on a hard bed, protect the cast with soft pads to avoid breaking the cast due to improper turning of the patient. 7, closely observe the peripheral blood circulation of the limb, pay attention to whether the color is purple, puffy, whether there is severe pain, whether the fingers (toes) are cold, numb, limited activity, etc. If the above conditions are found, the cast should be dissected immediately to avoid limb necrosis or ischemic contracture.
