One day, you are full of joy, pacing in front of the delivery room, that is, anxiety and excitement, a heart to meet the baby’s arrival, the baby was born but was told that the body has a defect, is a polydactyly …… In the face of this “thunderbolt from the sky”, you don’t know what to do, and then fell into endless contemplation and trepidation In the face of this “shock”, you do not know what to do, and then fell into endless contemplation and panic …… “All your life, you are different from normal people!” These words and the strange looks you get from the people around you keep coming back to your mind. The birth of every child with polydactyly is likely to mean a couple, a family, will have to live with the hurt hidden behind these words for the rest of their lives. Why is the baby like this? What should be done? All the parents of children with polydactyly, all over and over again in the bottom of the heart “tortured” their own …… Today, I listed the parents often asked about polydactyly five questions, and now, we one-time to make it clear. 1.Why polydactyly? The cause of polydactyly is very complex, but on the whole is divided into two kinds: one is internal, i.e., genetic factors, due to chromosomal abnormalities, gene mutation; the other is external, i.e., environmental factors, due to the embryonic period by external factors, such as biological, nutritional, pharmaceutical, radiation, endocrine, trauma and other factors affecting the occurrence of deformity. 2.How to prevent “polydactyly”? Eugenics, it is recommended that couples start from the period of preparation for pregnancy, try to maintain a healthy physical condition, happy mood. Strengthen the health care and nutrition during pregnancy, especially in the first three months of pregnancy, is the critical period of fetal limb development and formation, must be careful to use or not use drugs. Avoid respiratory infections, gastrointestinal infections, and viral infections such as rubella, measles, chicken pox, mumps, etc. during pregnancy, and avoid exposure to second-hand smoke, formaldehyde, radiation and other possible teratogenic factors in the embryo. 3, “polydactyly” can be found during pregnancy? Ultrasonography is the main method of clinical diagnosis of fetal limb deformities at this stage, but ultrasonography process there is a fetal fist, limb pressure, or due to positional factors, it is often difficult to detect finger deformities. Most polydactyly is found after birth. 4.How to treat polydactyly? Surgery is the only treatment for polydactyly. When a child is found to have polydactyly, “don’t be afraid, face it positively, and treat it as early as possible”, and take the child to the relevant specialties (hand and foot surgery) in a regular hospital as early as possible to avoid delaying the best time for surgery. In general, for simple polydactyly, the child in 6 months ~ 1 year old, as long as good health, weight (6kg or more), you can carry out surgery; for complex polydactyly, can be appropriate to delay the operation, generally between 1 ~ 2 years old. 5.Does surgical anesthesia affect the child? Syndactyly surgery needs to be carried out under general anesthesia, many parents are very worried about the general anesthesia will affect the child’s intelligence and development, in fact, do not worry too much about this problem, because there have been studies confirming that a single short period of time of anesthesia, on the child’s intelligence and development of little effect. It is very normal for parents to worry when their babies are young for surgery. As a doctor, I will tell the parents the relevant information so that they can have a clear picture in their mind, so that they will not be anxious.
