Application of drainage tube used intelligent squeeze device in the postoperation of radical mastectomy

Objective To investigate the effect on drainage tube with intelligent squeeze device on the radical mastectomy.Methods Totals of 120 patients with parasternal or axillary drainage tubes were randomly divided into group A with negative pressure ball (n =40),group B with the central low vacuum suction (n =40) and group C with intelligent squeeze device (n =40).24 hours,48 hours,72 hours of drainage fluid,each squeeze tube time,subcutaneous hemorrhage and effusion were compared among the three groups.Results 24 hours,48 hours,72 hours of drainage fluid in group C were significantly more than that in group A and B [(190±23)ml vs (140±14) and (165 ±12)ml; (125 ±15)ml vs (100 ±10) and (110 ±20)ml; (100±10)mlvs (80±15) and (90 ±13)ml; F=80.24,55.36,76.12;P＜0.05].Each squeeze tube time [(0.6 ± 0.2) mins] and tube retention time [(12 ± 2) d] were shorter than that in group A and B (P ＜ 0.05),as well as the incidence of flap necrosis,subcutaneous hemorrhage,and subcutaneous effusion (0％,0％,15％).Conclusions The intelligent squeeze device on drainage tube,with good efficiency,fewer complications and high security,is suitable for drainage in the radical mastectomy.
