Continuous High-Pressure Negative Suction Drain: New Powerful Tool for Closed Wound Management: Clinical Experience 고압력 연속 음압 흡입기를 이용한, 패쇄 창상의 치료의 새로운 해결방법 신, 승준 박, 명철 대학원 의학과 104849 신, 승준 Seroma Wall suction Continuous high-pressure negative suction drain 장액종 고압력 연속음압 흡입기 Background & Aims: Although various reconstructive flap surgeries have been successfully performed, there still are difficult wound complications, such as seroma formation, wound margin necrosis, delayed wound healing, and even flap failures. The negative-pressure wound therapy has been described in detail in the literature to assist open chronic/complex wound closure in reconstructive surgery. However, the negative-pressure wound therapy was difficult to be applied under the incisional closed wounds. Methods: A total of 23 patients underwent the various reconstructive flap surgeries with continuous high-pressure negative suction drain. Instead of using regular suction units, BarovacⓇ (50 - 90 mmHg, Sewoon Medical, Seoul, Republic of Korea) drainage tubes were connected to the　wall suction unit, providing continuous high-powered negative pressure.　In addition, continuous subatmospheric suction pressure (100 －300　mmHg) was applied. Outcome of the measures was obtained from the　incidence of seroma, volume of postoperative drainage, hospitalization　period, and incidence of other typical　wound complications. Dead space　was evaluated postoperatively with ultrasonography. Results: Using continuous high-pressure negative suction drain,　successful management of seroma was obtained without any major　complication such as wound infection, flap loss, and wound margin　necrosis, except for only 1 case of seroma after discharge from the　hospital. The indwelling time of the drain in the latissimus dorsi donor　site was significantly reduced in comparison with the authors’ previous　data (P = 0.047). The volume of drainage and hospitalization　period were also reduced; however, these were not statistically significant.　The dead space with continuous high-pressure negative　suction drain was more reduced than in the control group in the　immediate postoperative period and confirmed with ultrasonography.　 Conclusions: Continuous high-pressure negative suction drain might be the simple and powerful solution in the management of challenging closed wounds.
