Routine post-discharge wound care Discharge from the hospital does not mean that the wound is completely healed, and it still takes about 3 days for wound disinfection and gauze change. The signs of good wound healing include no significant difference in wound skin color from the surrounding normal skin, flat wound, no bulging, bulging, small holes or oozing, etc. The usual healing time is about 10 days after surgery. Possible causes of poor wound healing Most children with precordial heart disease are young, unlike adults who can protect their wounds on their own, so the risk of poor wound healing after surgery is relatively high, and the time of poor wound healing can range from a few days to several weeks after surgery, and there are cases of wound infection even one month after surgery. One of the reasons for poor healing is that the child has a rejection reaction to the absorption of the sutures in the wound, resulting in wound dehiscence, oozing, and then secondary infection that can lead to septicemia. This situation is mainly determined by the child’s constitution and is difficult to avoid. Another type of cause is that various reasons lead to poor wound healing followed by bacterial infection or direct bacterial infection leading to wound bulging, pus, and dehiscence. The common cases of postoperative wound infection include: newborns, low resistance; thin body, malnutrition, wound healing difficulties; obesity, wound easy to fat liquefaction; preoperative severe hypoxia, palliative surgery, still have hypoxia, cyanosis; preoperative and postoperative serious lung infection; postoperative chest drainage, pericardial effusion; postoperative child sweating, wound failure to keep dry and clean, child scratching the wound, child activity too much, etc. First of all, don’t be too anxious, postoperative wound infection is not uncommon, go to the hospital and stop changing the child’s medication by yourself; go to the hospital outpatient clinic and increase the frequency of medication changes, once a day if necessary, which is the most important aspect to promote wound healing; when there is pus in the wound, most of the wounds need to be incised and drained, and if necessary, sutured after the infection is controlled; when the child has fever and blood picture Antibiotics may be considered when elevated.
