Objective:

To compare the use of continuous constant negative pressure drainage and intermittent suction mode drainage in abdominal wall angioplasty to minimize the impact of complications.

Methods:

From May 2017 to August 2019, the Department of Medical Cosmetology and Plastic Surgery, Wuhan Third Hospital treated 76 female patients after expanded flap repair, aged 27-35 years, with an average age of 30.5±14.2 years, and 58 female patients after abdominal wall plasty, aged 38-55 years, with an average age of 47.8±7.8 years. They were divided into intermittent negative pressure drainage group and continuous negative pressure drainage group. The negative pressure values in different intervals were set according to the type of operation. The drainage volume, drainage time, incidence of hematoma, subcutaneous effusion, flap necrosis rate, primary wound healing rate and drainage related bleeding were recorded and compared between the two groups.

Results:

After expanded flap repair in 38 cases, flap necrosis occurred in 1 case and hematoma in 3 cases; After abdominal wall plasty in 29 cases, flap necrosis occurred in 0 cases and hematoma in 1 case. The primary healing of incision was higher ( P<0.05), the drainage volume was larger, but the drainage time was shorter ( P<0.05), and no bleeding related to drainage was observed. The effect of monitoring drainage was positively correlated with the effect of operation.

Conclusions:

Continuous and constant negative pressure drainage is related to the prognosis of patients undergoing expansion flap repair and abdominal wall plasty. It is helpful to improve the effect of plastic surgery and the quality of nursing work. It is an effective method for nursing management after plastic surgery.
