Surgical wounds are at increased risk of infection when left open to heal through secondary intention; they increase length of hospital stay, hospital costs, readmission rates, and patient morbidity. New technologies and methods of treating acute and chronic wounds are emerging. Two recent developments for the treatment of open wounds are noncontact low-frequency ultrasound (NCLFU) treatment and negative pressure wound therapy (NPWT).
This case series reports findings from 4 hospitalized patients with complex conditions who underwent colorectal surgery resulting in open abdominal wounds. The wounds were treated with NCLFU in combination with NPWT. Data were collected via retrospective review of medical records.
After concurrent treatment with NPWT (range, 13-18 days) and NCLFU (range, 5-9 treatments), wound areas in these 4 cases were reduced by 4.5% to 37% and wound volume decreased by 17% to 62%. Granulation tissue increased in the open tissue areas in all patients. In addition, 3 of the cases received a mesh graft.
Combination treatment with NPWT and NCLFU therapy with or without sharp debridement enhanced wound healing in the open abdominal wounds of these 4 patients.
手术伤口若任其通过二期愈合开放愈合，感染风险会增加；这会延长住院时间、增加住院费用、提高再入院率并增加患者发病率。治疗急慢性伤口的新技术和方法不断涌现。近期用于治疗开放性伤口的两项进展是非接触式低频超声（NCLFU）治疗和负压伤口治疗（NPWT）。
本病例系列报告了4例病情复杂的住院患者的研究结果，这些患者接受了结直肠手术后腹部出现开放性伤口。伤口采用NCLFU联合NPWT进行治疗。通过回顾病历收集数据。
在同时接受NPWT（范围为13 - 18天）和NCLFU（范围为5 - 9次治疗）后，这4例患者的伤口面积减少了4.5%至37%，伤口体积减少了17%至62%。所有患者开放组织区域的肉芽组织均增多。此外，其中3例患者接受了网状移植物。
NPWT与NCLFU联合治疗，无论是否进行锐性清创，均促进了这4例患者腹部开放性伤口的愈合。
