Can fat liquefaction and drainage recur after caesarean section? Fat liquefaction is one of the main reasons for poor healing of surgical wounds. Especially when there is a large amount of fat in the incision, the mechanism may be that the high temperature generated by electrosurgical excision procedure causes superficial burns of subcutaneous adipose tissue and some adipose cells are denatured due to thermal injury.
At the same time, the capillaries in adipose tissue are embolized due to coagulation, which further hinders the blood supply of the hypertrophic adipose tissue with poor blood supply, and the adipose tissue undergoes aseptic necrosis after operation, forming more exudates, which affects wound healing.
It is speculated that the fat liquefaction of incision is related to obesity and whether the skin and subcutaneous tissue are cut with high frequency electrotome during operation. The mechanism may be that the high temperature generated by electrotome causes superficial burns of subcutaneous adipose tissue, and some adipose cells are denatured due to thermal injury. At the same time, the capillaries in adipose tissue were embolized due to thermal coagulation, which further hindered the blood supply of hypertrophic adipose tissue with poor blood supply. After operation, adipose tissue was aseptic necrosis, forming more exudates, which affected wound healing.
Because fat has no nociceptive nerve, people are painless when liquefied, which usually occurs 5-7 days after operation. Only when the stitches are removed will you see a yellowish liquid at the wound. If you don't pay attention, it will be regarded as sweating. Wound healing is not good, there is no obvious pain after pressing, and there is no sign of necrosis or redness around.
How long does it take for caesarean section to absorb thread? When women have caesarean section, they usually use absorbable suture at the abdominal incision. If there is an absorbable line in the fat layer, it will not be absorbed. At this time, it may often cause local pain in the incision, and these threads may also come out of the incision. If this happens, it is usually only necessary to take out the extra thread from the incision and sew it again. At this time, it is generally recommended to suture with silk thread, and then remove the thread after the incision returns to normal.
The absorbable suture is sutured inside the wound, which can be absorbed by itself in subcutaneous or adipose tissue, and the conventional absorption time is about one month. If the absorbable thread is not absorbed for a long time, it needs to be taken out. If necessary, a small incision should be made at the wound under local anesthesia, and the absorbable suture should be pulled out intermittently. Absorbable suture takes different time to absorb, for example, it can only be absorbed in two months, and it is normal not to absorb it after 20 days or one month, and then it can be absorbed. Some patients will reject the absorbable thread, the wound will be red and swollen, and even secondary infection. Absorbable suture should be taken out when necessary, and the wound should be sutured after the inflammation is controlled.
