The girdle is a constricting ring that is formed at the beginning of fetal development when the normal development of the limb is hindered by the amniotic band. Some of these bands may be more pronounced, resulting in short fingers or syndactyly, and usually require surgery at the recommendation of the doctor when appropriate. However, there are some cases that are not so obvious and are often overlooked by parents, and some parents are even proud of this. Because the appearance of this band syndrome is very similar to that of obesity, which makes it impossible for many parents to tell the difference, and naturally, they are not clear about what is at stake. The presence of the girdle is like a thin and tough rope strangling the child’s limbs on a regular basis, which affects blood flow and compresses nerves, and if not released in time, may lead to distal limb deformities. So how should parents distinguish whether their children are harnessed or obese? In fact, only need three steps: The first step, first look at the baby limb on the fold is not a whole circle. Generally obese folds are half a circle or part, if there is a whole circle of folds, parents should be alert to whether the band is caused by. Second step, press the skin around the folds, if there is a relatively hard situation, basically you can confirm that it is the belt syndrome, because the obesity caused by the folds, the surrounding skin is relatively soft, will not appear very hard situation. Step 3: Push the skin around the fold with your hand to see if it disappears with the extension of the skin. If the fold still exists on the limb after the extension, parents should take the child to the hospital for examination as soon as possible. Because this is likely to be the bandage syndrome, need to be loosened as soon as possible, do not take any chances, if necessary, when the emergency treatment.
