ABSTRACT
Objective To observe the quantity of drainage fluid after operation and to evaluate the application of negative pressure drainage in skin soft tissue expansion. Methods The silica gel tube of 2 mm inside diameter with multi holes on sides was set under the skin soft tissue expander in 48 patients, then drained from upper incision or another incised hole,and connected with negative pressure apparatus. Results After operation, the quantity of drainage was from less than 5 ml to no more than 50 ml, averaged 16 ml. Conclusion For an operation with expansion capability above 100～200 ml,setting the negative pressure drainage as a routine is a most simple and effective method to prevent and treat bleeding and hematoma formation.It can produce effects on reducing the early complications such as hematoma and infection.
