For small children, atrial septal defect blocking is intravenous general anesthesia, but do not worry too much, the time of general anesthesia is not very long, because for a skilled interventional surgeon, if the patient is selected with very good indications, the time of atrial defect intervention, from the puncture to the completion of the release of the whole blocker, usually does not exceed half an hour, and the whole process of general anesthesia will not exceed one hour at most. With the development of medical technology nowadays, there is basically no harm or sequelae for the child, so parents should not worry because of general anesthesia. Of course, if the child is very old and has reached the age of teenagers, or even adults in their twenties, the procedure of atrial defect intervention can also be performed by means of local anesthesia. In short, judgment is still needed. Because the age of precordial findings is getting younger and younger nowadays, and the time to do the procedure is getting earlier and earlier, 90% of the children are young age children. It is obviously unrealistic and impossible to do local anesthesia, so basically children who undergo surgery go through general anesthesia, and general anesthesia or local anesthesia is not a factor in deciding the way of surgery.
