Experience of incision continuous negative pressure suction in gynecological or obstetric abdominal surgery

Objective: To assess the efficacy of applying subcutaneous continuous negative pressure drainage to gynecological and obstetric abdominal operation. Methods: One hundred and twenty patients undergone abdominal surgery with poor healing were included and randomly allocated to either group of treatment or controls( n = 60 for each). The treatment group were managed with one drainage tube placement between the anterior wall of rectus sheath and subcutaneous fat to achieve continuous postoperative negative pressure suction,and the control group were applied with conventional incision suturing. The incision healing was observed in the two groups. Results: Class-A wound healing rate was significantly higher in the treatment group than the control group( P 0. 01). The two groups had statistical difference regarding the abdominal closure( P 0. 05),yet remained no difference in hospital stay( P 0. 05).Conclusion: Subcutaneous continuous negative pressure drainage tube may promote the early recovery for women with poor incision healing after gynecological or obstetric abdominal surgery.
