Title: Study on effects of continuous center attract negative pressure
Abstract: Objective To study the function of continuous center attract negative pressure in preventing subcutaneous hydrops after radical mastectomy in breast cancer.Methods The patients accorded with the clinically standard after radical mastectomy were randomly divided into control group and experiment group,after radical mastectomy,the control group patients were tied up for 3 ~ 5 days by using normal regulatioas continuous single tube or double tube connecting a negative pressure,or with a bottle negative pressure to lead to flow and the elasticity bandage.The experiment group made use of continuous center attract negative pressure,pressure maintained at -0.01 ~ -0.03 Mpas(-100 ~ -225 mmHg) keeping on negative pressure,continuously for 3 ~ 5 days,we observed and compared the incidence rate of subcutaneous hydrops and flap necrosis,and recorded a related data to have statistical analysis.Results The subcutaneous hydrops in the experiment group was 2 cases (8%),while control group occurred 9 cases (35%).The incidence rate of subcutaneous hydrops in the experiment group was obviously lower than that of control group(P < 0.05).No skin flap necrosis was noted in the experiment group (0%),while 6 cases found in control group(23%).The skin flap necrosis incidence rate in the experiment group was lower than that of control group with statistical significant difference (P < 0.05).Conclusions Continuous center attract negative pressure can be used in radical mastectomy to prevent the incidence rate of subcutaneous hydrops and flap necrosis,helping the wound to heal.Therefore it is worth to be applied in clinic.
