ABSTRACT
Abstract Damage control surgery principles allow delayed management of traumatic lesions and early metabolic resuscitation by performing abbreviated procedures and prompt resuscitation maneuvers in severely injured trauma patients. However, the initial physiological response to trauma and surgery, along with the hemostatic resuscitation efforts, causes important side effects on intracavitary organs such as tissue edema, increased cavity pressure, and hemodynamic collapse. Consequently, different techniques have been developed over the years for a delayed cavity closure. Nonetheless, the optimal management of abdominal and thoracic surgical closure remains controversial. This article aims to describe the indications and surgical techniques for delayed abdominal or thoracic closure following damage control surgery in severely injured trauma patients, based on the experience obtained by the Trauma and Emergency Surgery Group (CTE) of Cali, Colombia. We recommend negative pressure dressing as the gold standard technique for delayed cavity closure, associated with higher wall closure success rates and lower complication and mortality rates.
ABSTRACT
Objective@#To investigate the effect of different negative pressure of wound negative pressure dressing (NPD) on the survival of full-thickness skin grafts of patients.@*Methods@#One hundred and eleven patients who need skin grafting, conforming to the inclusion criteria were hospitalized in our unit from August 2012 to March 2017, and their clinical data were retrospectively analyzed. Forty-seven patients hospitalized from August 2012 to October 2015 were assigned into traditional treatment group. Sixty-four patients hospitalized from November 2015 to March 2017 were divided into -9.975 kPa negative pressure treatment group (n=34) and -13.300 kPa negative pressure treatment group (n=30). Patients in traditional treatment group received conventional dressing after full-thickness skin grafting. Patients in -9.975 kPa and -13.300 kPa negative pressure treatment groups received -9.975 kPa and -13.300 kPa NPD based on traditional treatment after vacuum sealing, respectively. Dot necrosis area of skin grafts and erosion and escharosis of graft edges of patients in the three groups on post operation day 10 were observed. The percentage of dot necrosis area of skin grafts and occurrence rate of erosion and escharosis of skin graft edges were calculated, respectively. Data were processed with chi-square test, Fisher′s exact test, and Kruskal-Wallis H test.@*Results@#Percentages of dot necrosis area of skin grafts of patients in traditional treatment group and -9.975 kPa and -13.300 kPa negative pressure treatment groups were 17.81%, 3.20%, and 3.00%, respectively. Percentage of dot necrosis area of skin grafts of patients in traditional treatment group was significantly higher than that in -9.975 kPa and -13.300 kPa negative pressure treatment groups (Z=-5.770, -4.690, P<0.001). Percentages of dot necrosis area of skin grafts of patients in -9.975 kPa and-13.300 kPa groups were close (Z=-0.619, P>0.05). The occurrence rates of erosion and escharosis of skin graft edges of patients in traditional treatment group and -9.975 kPa and -13.300 kPa negative pressure treatment groups were 78.7% (37/47), 32.4 (11/34), and 36.7% (11/30), respectively. Erosion and escharosis of skin graft edges of patients in -9.975 kPa and -13.300 kPa negative pressure treatment groups were better than those in traditional treatment group (P<0.001). Erosion and escharosis of skin graft edges of patients in -9.975 kPa and -13.300 kPa negative pressure treatment groups were close (P>0.05).@*Conclusions@#The use of -9.975 kPa and -13.300 kPa NPD in skin grafts after full-thickness skin grafting significantly diminishes the occurrence rates of dot necrosis area of skin grafts and erosion and escharosis of graft edges.
ABSTRACT
Background: Delayed wound healing is a significant health problem, particularly in older adults. In addition to the pain and suffering, failure of the wound to heal also imposes social and financial burdens. Vacuum-assisted closure (VAC) therapy has been developed as an alternative to the standard forms of wound management, which incorporates the use of negative pressure to optimize conditions for wound healing and requires fewer painful dressing changes. Aim: To assess whether the management of non-healing wounds using VAC therapy will result in improved efficacy and safety outcomes compared with conventional methods. Materials and methods: Present prospective, time bound study was done for 1 year from January 2016 to December 2016 over 50 subjects (25 cases and 25 controls). Details of cases were recorded including history and wound characteristics. Routine investigations were done. Follow up with size of wound, appearance of granulation tissue after day 0, 3, 6, 9, 12 and so on dressings were done. Results: Patients managed with VAC had increased rate of r epithelialization and fewer patients required repeat split thickness skin graft to the same site. VAC was more effective at treating various chronic and complex wounds, as there was a significantly greater reduction in wound volume, depth and treatment duration. Conclusion: VAC results in better healing than standard methods, with few serious complications. More rigorous studies with larger sample sizes assessing the use of VAC therapy on different wound types are required
ABSTRACT
Decubitus ulcer is a pressure-induced ischemia-reperfusion injury overlying a bony prominence. Various dressing methods have been developed to treat it, but clinical management is still a challenging practice. A patient presented with stage IV decubitus ulcer on the left lateral side of the buttock, which was caused by compulsively lying down on the left side due to schizophrenia. The ulcer was resistant to occlusive dressing method for five weeks. However, the patient successfully recovered in three weeks by our applying a negative pressure dressing with the portable vacuum-assisted closure (VAC) system. Our experience shows negative pressure dressing can be effectively used to treat intractable decubitus ulcer in outpatient settings.
