General anesthesia is needed for baby syndactyly and syndactyly surgery because with general anesthesia, we are able to monitor the baby’s vital signs better, the baby will not move around under general anesthesia, and we are able to perform the surgery for the child better. Many parents worry that general anesthesia will affect the baby’s intelligence and height. In fact, it is only a single short period of general anesthesia, which is not long and will not affect the baby’s intelligence and height. Therefore, parents do not need to worry too much, and let the baby receive general anesthesia normally. So when may have an effect? In a part of the repeated multiple general anesthesia of the baby, there will be a very small part of the baby’s ability to read quickly is not so good, fine activities have a little impact, other than no effect. Babies with syndactyly should have their fingers surgically separated as early as possible, if possible. Separate the fingers together as early as possible, will be conducive to the growth of the baby’s fingers, but also conducive to the healing of the wound as soon as possible.
