We recently developed continuous negative pressure therapy with irrigation (NPI) and successfully applied it to an infected digit with a narrow wound. With this technique, however, the dressing circumferentially wraps the digit or hand, and the pressure that the digit or hand receives and the influence on peripheral circulation are unclear. In this report, we evaluated the external pressure that a digit and hand received during NPI in vitro. Under circumferential NPI dressing, the skin perfusion pressure (SPP) of the peripheral portion was measured. Pressure was maintained at 1.3 mm Hg, and suction pressure ranged from -50 to -200 mm Hg. The pressure that a digit or hand receives during NPI is much lower than that at which tissue may be damaged (40–50 mm Hg). The SPP of the peripheral portion was much higher than 40 mm Hg, which is the pressure at which wound healing may be predicted. In clinical cases, NPI has been useful for wound bed preparation.

Cosmetic Results

When tendons, bones or joints are exposed in infected digits, functional and cosmetic sequelae are frequent. We propose continuous negative pressure therapy with irrigation (NPI) for an infected digit with an open wound. Continuous NPI was evaluated in vitro and subsequently applied to a clinical case. Acceptable functional and cosmetic results were obtained without any problems when continuous NPI was performed in the clinical case. Continuous NPI may be a useful alternative for treatment of an infected digit with an open wound.

CONTEXT: Complications from diabetes mellitus affecting the lower limbs occur in 40 to 70% of such patients. Neuropathy is the main cause of ulceration and may be associated with vascular impairment. The wound evolves with necrosis and infection, and if not properly treated, amputation may be the end result. Surgical treatment is preferred in complex wounds without spontaneous healing. After debridement of the necrotic tissue, the wound bed needs to be prepared to receive a transplant of either a graft or a flap. Dressings can be used to prepare the wound bed, but this usually leads to longer duration of hospitalization. Negative pressure using a vacuum system has been proposed for speeding up the treatment. This paper had the objective of analyzing the effects of this therapy on wound bed preparation among diabetic patients. CASE SERIES: Eighty-four diabetic patients with wounds in their lower limbs were studied. A commercially available vacuum system was used for all patients after adequate debridement of necrotic tissues. For 65 patients, skin grafts completed the treatment and for the other 19, skin flaps were used. Wound bed preparation was achieved over an average time of 7.51 days for 65 patients and 10 days for 12 patients, and in only one case was not achieved. CONCLUSIONS: This experience suggests that negative pressure therapy may have an important role in wound bed preparation and as part of the treatment for wounds in the lower limbs of diabetic patients.

A Prospective Study

The study aims to assess the significance of negative pressure therapy in the treatment of 1 January 2014 - 31 June 2017. The objectives intend to evaluate the healing time required after applying the method and the functional consequences for the patient. A prospective study was conducted on a sample of 31 patients with various tipe of wounds which were monitored their clinical course between September 2014 - February 2017, following negative pressure therapy. There were used vacuum assisted closure devices (VAC � -Hartman) in order to apply negative pressure to the wound, while complying with specified settings in accordance with patients� outcome. Healing was obtained in all cases, to an average hospital stay of 30 days and 12 days of therapy application.The negative result of microbial cultures was obtained after an average of 7.55 days by simultaneous application of negative pressure and antibiotic treatment according to the antibiogram. After basic treatment of the wound, auxiliary methods such as negative pressure contribute to the healing. Evolution was favorable with wound granulation in 95% cases, which allowed surgery under local anesthesia, and defect was covered with skin graft. VAC therapy falls into the last group of treatments by eliminating healing inhibitors. This regenerates the wound in a damp environment and essentially turns an open wound into a closed system.

The study aims to assess the significance of negative pressure therapy in the treatment of diabetic foot.The objectives intend to evaluate the healing time required after applying the method and the functional consequences for the patient. A prospective study was conducted on a sample of 37 patients with diabetic foot were monitored their clinical course between September 2014 - April 2017, following negative pressure therapy. There were used vacuum assisted closure devices (VAC � -Hartman) in order to apply negative pressure to the wound, while complying with specified settings (negative pressure, time of use of a kit) in accordance with patients� outcome.There were monitored changes in wound size (planimetric and volumetric measurement), their bacterial load and duration of treatment. Healing was obtained in all cases, to an average hospital stay of 27.3 days and 8 days of therapy application.The negative result of microbial cultures was obtained after an average of 6.45 days by simultaneous application of negative pressure and antibiotic treatment according to the antibiogram. Skin grafts were necessary to close the defect in 4 cases. After basic treatment of the wound, auxiliary methods such as negative pressure contribute to the healing.In patients with diabetic foot who were required surgical intervention, the use of negative pressure therapy yielded a significant benefit in the preservation of the affected limb, after minimal excision.The results we obtained throughout our experience recommend use of NPTW technique as indication for abdominal wall surgery in closing abdominal wall defects, compartment syndrome and surgical site infection after prosthetic mesh.
