Study on the Prevention and treatment of fat liquefaction of abdominal incision

OBJECTIVE Fat liquefaction of abdominal incision is the more common complications after abdominal surgery,and the main surgery task is to prevent the occurrence of fat liquefaction.METHODS We washed the incision with large amounts of physiological saline before closure of subcutaneous fat.The treatment principle of fat liquefaction was not to expose all of the incision when less exudates;Open local Incision with an additional 10% hypertonic saline drainage can achieve good results;Incision open,unobstructed drainage and use of antibiotics are necessary when more exudates or exudative a wider range;The whole incision drainage used hypertonic saline or gentamicin gauze.Two stage suture was implemented when the fresh granulation tissue was formed.RESULTS The fat liquefaction rate of the experimental group did not show significant difference compared with the control group when Subcutaneous fat thickness was less than 2cm(P﹥0.05);The fat liquefaction rate of the control group(Subcutaneous fat thickness was less than or equal to 2cm)was significantly different compared with the control group(less than or equal to 4cm)(P﹤0.01);The fat liquefaction rate of the experimental group was significant difference compared with the control group(Subcutaneous fat thickness was more than or equal to 4cm)(P﹤0.01).CONCLUSION Effective measures should be taken to prevent the fat liquefied,including preoperative to correct anemia and hypoproteinemia,controlling blood glucose below than 10 mmol/L,proper use of electrotome,low-current cutting subcutaneous tissue,accurately and quickly cutting the fat tissue,so as to avoid repeated cutting and prolonged exposure of fat tissue,washing incision with large amounts of physiological saline before closure of subcutaneous fat.
