OBJECTIVE

The aim of this small pilot audit was to record the performance of an adjustable Velcro compression wrap, ReadyWrap, and the experiences of patients and health-care professionals using the system as a self-care option for the management of venous and lymphatic leg conditions in both the treatment and maintenance phases.

METHOD

This audit was held within a 4-week review period. Participants included venous leg ulcer (VLU) patients with and without oedema, and patients with lymphoedema. Where open wounds were present they were managed with debridement, skin care and dressings according to clinical need. Lymphoedema patients received manual lymphatic drainage and skin care regimens as per standard practice. The Velcro system evaluated formed part of a treatment pathway with compression bandages and/or compression hosiery as clinically indicated. Patients, carers and health-care professionals applied the garments following assessment and training. Objective data recorded included change in circumferential measurements and improvement in wound status. Observation of health-care professionals, patients and carers with regard to the comfort and ease of application/removal of the device were recorded.

RESULTS

There were 17 patients included in the audit. Within the 4-week period a reduction in limb circumference was recorded in all cases. Improvements in open wounds were recorded in most cases. Following the 4-week audit period 94% of the application of the device was performed by either the patient (59%) or the carer (35%) thereby reducing the health-care professional contact that was required for application.

CONCLUSION

Early results in this small audit demonstrate that this adjustable Velcro compression wrap may provide a simple, clinically effective and patient-acceptable solution for self-care with compression. Use of this type of device could have the potential to reduce overall health-care burden by reducing necessary skilled treatment visits and/or cost while still achieving good clinical outcomes. Further studies are required to confirm this pilot study and provide additional data.

Background During cardiac surgery with heart-lung-machine support, abdominal swabs are routinely used to adsorb blood from the operation field. In part, abdominal swabs exhibit procoagulant activity, which is usually considered harmless. However, coagulation induction and abnormal clot formation on the surface of abdominal swabs in the operation field may, if the blood is retransfused into the extracorporeal circuit, lead to severe thromboembolic complications. The aim of the present study was to elucidate the origin of the unexpected blood clotting upon contact with hypercoagulant swabs. Methods The coagulant properties of three abdominal swabs were characterized using a simple clotting test and human whole blood, which was anticoagulated with different heparin concentrations. Eluates prepared from the abdominal swabs and the color stabilizer polydiallyamine (PDAA) were incubated with blood and blood clotting was investigated. Furthermore, the effects of the abdominal swabs on blood clotting time and on heparin were investigated. Results Our data show that the three abdominal swabs as well as the respective eluates exhibit distinctive coagulant properties. The abdominal swab with the highest hypercoagulant effect significantly reduced blood clotting time and also led to a reduction in free heparin. PDAA does not induce activation of the coagulation system. Conclusion The data indicate that the hypercoagulant swab reduces the clotting time and the concentration of free heparin. Abdominal swabs used during complex cardiac surgery with heart-lung-machine support should definitely be tested for their coagulant properties using appropriate tests before clinical applications, as it cannot be specified what leads to their hypercoagulant property.

INTRODUCTION

Operative and interventional treatment of Boerhaave's syndrome include closure of the esophageal defect and drainage of the septic focus. Initial reports on the use of endoscopic vacuum therapy (EVT) of Boerhaave's syndrome are now available. This article describes the experiences gained from the clinical application in two patients using this new surgical endoscopic procedure. The current literature regarding treatment of Boerhaave's syndrome is presented.

MATERIAL AND METHODS

Open-pore drainage is endoscopically placed either through the transmural defect in the extraluminal wound cavity (intracavitary EVT) or overlapping the defect into the esophageal lumen (intraluminal EVT). The application of a negative pressure results in active drainage directed to the lumen and simultaneously in defect closure. Through these therapeutic measures the perforation defect and the septic focus can be healed. Open-pore drains are manufactured from drainage tubes and open-pore foam or an open-pore film.

RESULTS

In both patients the distal esophageal perforation defects were completely healed using EVT. In 1 patient the treatment with EVT alone lasted 8 days. For the second patient EVT was combined with an open thoracotomy for decortication of pleural empyema. The treatment with EVT lasted 23 days and 1 cycle of EVT was carried out with an new open-pore film drainage (OFD). Surgical treatment to close the defect or an esophageal resection was not necessary for both patients. In the currently available studies and single case reports of ETV for Boerhaave's syndrome, 11 patients (84 %) of a total of 13 patients have been successfully treated.

CONCLUSION

First clinical experiences have demonstrated that with EVT draining of the septic focus and closure of the Boerhaave defect at the gastroesophageal junction can be achieved. The EVT is an organ-preserving endoscopic surgical treatment, which can be an alternative and complementary to traditional surgery.

Maceration is the elixation of the skin by prolonged exposure to moisture that impedes healing due to failure of the skin protection and possible microbial infections. Modern wound dressings are expected to maintain a humid wound milieu without allowing exposure of the peri-wound skin to exudate and subsequent damage of the skin by maceration. Hence, it is of interest to analyze and compare the fluid management of PU-foam dressings under standardized conditions as close as possible to a real life situation. Therefore, a vertical maceration model using 40 mmHg compression was developed.
