The aim of this pilot study is to obtain preliminary results comparing topical oxygen therapy (TOT) and vacuum assisted closure (VAC) in terms of its ability to accelerate wound healing. METHODS: This non-randomised prospective study included patients with age 16-50 years, wound size ≥ 16cm2 and present below knee joint within seven days of occurrence. Bates-Jensen wound assessment tool (BWAT) was used for evaluation at 8-day interval along with percent area reduction at final follow up. RESULTS: Mean number of cycles required in VAC and TOT group were 1.97 (range 1-3) and 2.1 (range 1-3) (each cycle of 5 days) per patient respectively. Percent area reduction was significantly higher in the VAC group (34±9.7%) than TOT (11.3±3.8%) group at final follow up (p<0.05). TOT patients had better improvement in epithelialization compared to VAC at last follow up. More extensive debridement was needed in patients of TOT than VAC. There was no significant difference between final score in both groups. CONCLUSION: TOT appears to be comparable to well-established VAC in treatment of fresh traumatic wounds below the knee joint. Further large scale, multicentric and randomised studies comparing both these modalities of treatment should be the way forward

Purpose: Negative pressure wound therapy (NPWT) has revolutionized wound care, but its high cost reduces the procedure's availability. To solve the problem, streamlined vacuum dressings systems have been proposed, but the utility of these devices has been poorly studied. The objective of this study was to evaluate a simplified vacuum dressing system model (SVDM). Methods: Randomized clinical trial in which wounds were treated with SVDM compared to a complex occlusive dressing (silver hydrofiber, SHF). The analyzed outcomes were cleaning, presence of granulation tissue, clinical appearance, and indication for surgical closure of wounds. Results: Fifty injuries were treated (25 in each group), most located on lower limbs. SVDM proved to be more effective than SHF in the evaluated outcomes. Wound recalcitrance reduced the effectiveness of the equipment used. Despite its efficacy, complications occurred, the most frequent related to dressing changes: minor bleeding, foam adherence to a wound bed, and pain. Only for bleeding no favorable risk-benefit ratio was found. There were no severe complications, worsening conditions of injuries, or deaths. Conclusions: SVDM proved to be an effective and acceptably safe device for managing studied wounds.

Objective: To investigate the clinical effects of in situ perforation of preserved split scar matrix in combination with scalp transplantation and vacuum sealing drainage in the treatment of hypertrophic scar in non-functional sites after burns. Methods: A retrospective observational study was used. From June 2017 to June 2019, 33 patients (24 males and 9 females, aged 8-50 years) who met the inclusion criteria with hypertrophic scars in non-functional sites outside the face after burns were treated in General Hospital of TISCO (the Sixth Hospital of Shanxi Medical University). All patients underwent scalp transplantation after perforation of retained split scar matrix in situ (with scar thinning area of 90-500 cm2), and then the vacuum sealing drainage was performed. The hematoma and infection of wounds were observed on the 7th day after operation. At the same time, the survival rate of skin grafting was observed and calculated. The flatness and thickness of the scar in the operative area were observed in 12 months after operation, and the itching and pain of the patients were recorded. Vancouver Scar Scale was used to score the scar of patients before operation and at 3, 6 and 12 months after operation. The healing time and hair growth of donor site were observed. Data were statistically analyzed with repeated analysis of variance, paired sample t test and bonferroni correction. Results: On the 7th day after operation, local subcutaneous hematoma appeared in the wound of 2 patients, which healed after dressing change; no infection occurred. On the 7th day after operation, the survival rate of skin grafting of patients was 94.6%-99.0%(96.8±1.2)%. Scar flatness was well, the thickness of scar was not significantly higher than that of normal skin in 12 months after operation, and the symptoms of itching pain of patients disappeared or significantly relieved. Vancouver Scar Scale scores of patients before operation and at 3, 6, and 12 months after operation were 12.1±2.8, 8.5±1.5, 7.6±1.6, 6.7±1.3, respectively, and the scores of 3, 6, and 12 months after operation were all significantly lower than that before operation (with t values of 4.48, 4.06, and 3.97, respectively, P<0.01). All the donor sites of the head healed well in 4-7 days after operation. By 3-6 months after operation, all patients had good hair growth in the donor site and achieved no scar healing. Conclusions: The treatment of hypertrophic scar in non-functional sites outside the face after burns by in situ perforation of preserved split scar matrix in combination with scalp transplantation and vacuum sealing drainage can effectively improve the appearance of hypertrophic scar in non-functional areas after burn and reduce its degree of hyperplasia, with scar-free donor site healing.

On November 17, 2013, the Second Affiliated Hospital of Kunming Medical University admitted a 23-year-old male patient with a high-temperature steel bar penetration injury from scrotum to buttocks who was transferred from another hospital. Expanded debridement, suture, and drainage of the perineum, right thigh, and right hip were performed as soon as possible after admission. A sputum suction tube was used as the guide mark for expanded debridement during the operation to ensure the accuracy of the direction and scope of expanded debridement. The incision was treated with vacuum sealing drainage (VSD) and full drainage. On the 20th day after the operation (the 25th day after admission), the unhealed wound was transplanted with split-thickness skin graft from the right thigh, and the drainage of the operation area and dressing change were strengthened. On the 53rd day after injury, the patient was discharged after complete wound healing. This case suggests that VSD after early debridement is an effective means to treat high-temperature steel bar penetration injuries.

Wound repair has always been one of the key issues of clinical concern. In recent years, negative pressure wound therapy (NPWT) has played an increasingly active role in promoting various wound repairs, not only for the treatment of common acute and chronic wounds, but also for closure of surgical incisions, preparation of wounds before skin transplantation, fixation of skin grafts after transplantation, and treatment of some complex thoracic and abdominal trauma. This review aims to summarize the clinical application of NPWT in wound treatment and the related latest research progress, and to preliminarily discuss its future development prospects.

El objetivo de este trabajo es normatizar el uso de la terapia de presión negativa de heridas complejas en neonatos. La iniciativa surge a partir de la negativa de nuestros proveedores locales de proporcionarnos el material del sistema VAC (cicatrización asistida por vacío), por temor a las posibles complicaciones por su uso en neonatos y escasa bibliografía al respecto. Se presentan 2 casos tratados en neonatos entre 2018 y 2021, y se acompaña de revisión bibliográfica encontrada, de diferente etiología. Con las conclusiones obtenidas, se pretende establecer al VAC como una herramienta terapéutica eficaz en neonatos, de igual manera que se aplica, en toda herida compleja que lo requiera, sin importar la edad del paciente

The goal of this work is to standardize the use of negative pressure therapy for complex wounds in newborns. The initiative arises from the refusal of our local suppliers to provide us with the VAC (vacuum-assisted healing) system material, for fear of possible complications from its use in newborns and little literature about it. There are 2 cases treated in neonates between 2018 and 2021, and it is accompanied by found bibliographic review of different etiology. With the conclusions obtained, it is intended to establish the VAC as an effective therapeutic tool in neonates, just as it is applied, in any complex wound that requires it, regardless of the age of the patient

OBJECTIVES: To evaluate the efficacy of autologous platelet-rich plasma (PRP) gel in the treatment of refractory pressure injuries and its effect on wound healing time and quality of life of patients. METHODS: A random number table method was used to group 102 patients with refractory pressure injuries into either a control group (CG) (51 cases) receiving negative pressure wound therapy (NPWT) or a study group (SG) (51 cases) receiving NPWT+PRP gel. RESULTS: The total efficacy rate in the SG (92.16%) was higher than that in the CG (76.47%) (p<0.05). The SG exhibited lower visual analog scale (VAS) scores and pressure ulcer scale for healing (PUSH) scores, smaller wound sizes and depths, and shorter wound healing times than the CG after 21 days of treatment (p<0.05). After 6 months of treatment, the SG scored higher than the CG on the psychological, physiological, social functions, and daily activity domains on the World Health Organization Quality of Life (WHOQOL-BREF) scale (p<0.05). The incidence of postoperative complications in the SG (13.73%) was not significantly different from that of the CG (7.84%) (p>0.05). CONCLUSION: In the treatment of refractory pressure injuries, PRP gel can accelerate wound healing, reduce wound pain, shorten the treatment cycle, regulate tissue inhibitor matrix metalloproteinase-1 (TIMP-1) and matrix metalloproteinase-9 (MMP-9) levels and the expression of specific proteins in granulation tissue, reduce the levels of the inflammatory factors interleukin-1β (IL-1β), IL-8, and tumor necrosis factor-α (TNF-α), and improve the quality of life of patients without increasing complications.

Abstract Introduction: Negative pressure wound therapy (NPWT) has significantly improved outcomes in individuals with superficial and deep sternal wound dehiscence (SWD). We report our experience with NPWT to evaluate factors influencing effectiveness, duration of treatment and postoperative hospital stay. Methods: We reviewed 92 patients with postoperative SWD following a median sternotomy. Patients were divided into 2 groups: those with a superficial SWD (Group 1; 72, 78%) and those with a deep SWD (Group 2; 20, 28%). Group 1 was further divided into 3 subgroups based on NPWT duration. Results: In both groups, none of the preoperative characteristics examined showed a significant association with longer NPWT duration. In Group 2, there was a trend for postoperative bleeding and neurological complications to be associated with longer treatment duration. In the entire series, staph infection resulted a weak predictor of NPWT duration. In each Group 1 subgroup and in Group 2, treatment days were compared with duration of hospitalization until discharge. Mean post-NPWT hospital stay was 6 days in subgroup 1, 12 days in subgroup 2 and 20 days in subgroup 3 (P<0.0001). At a median 3-year follow-up, there were 4 late deaths, none related to wound complications. No cases of SWD recurrence were observed. Conclusion: Our results confirm the effectiveness of NPWT in SWD management, while excessive treatment duration might have a negative impact on the length of hospital stay. Further studies are needed to define an optimal use of NPWT protocol.

Pressure ulcers are quite distressing, and they cut across all age groups. Aside from increasingmortality, it results in protracted hospital stay and an upsurge in the consumption of healthcare resourcesPressure ulcers are considered to be essentially preventable, but in order to prevent them it is important to identify the people most at risk and deliver timely preventative care. In case of severe acute respiratory distress syndrome (ARDS), as in coronavirus dis­ease 2019 (COVID-19) affected patients, prone position and invasive ventilation improve the clinical status of this group of patients. This form of therapy is associated with an increased risk of facial pressure ulcers. When pressure ulcer occurs, appropriate documentation of each ulcer and staging of the ulcer are essential for good wound assessment.Treatment involves, assessing the nutritional needs of the patient, management of infections, removal of necrotic tissue, maintenance of a moist environment for wound healing, and possibly surgery

SUMMARY OBJECTIVE To investigate the clinical efficacy of cefazolin sodium pentahydrate combined with vacuum sealing drainage (VSD) in the treatment of open fracture complicated with soft tissue injury. METHODS Sixty-three patients with open fracture complicated with soft tissue injury were divided into observation (n = 33) and control (n = 30) groups. After surgical reduction, fixation, and repair of the fractures, the control group was treated with VSD for 10 days, and the observation group was treated with cefazolin sodium pentahydrate based on VSD for 10 days. The infection control time was recorded. After treatment, the pain of patients was evaluated. Before and after treatment, the serum levels of C-reactive protein (CRP), interleukin (IL)-6, IL-8, tumor necrosis factor α (TNF-α), cortisol, epinephrine, norepinephrine, and glucose were detected. After 6 months of treatment, the total effective rate of the treatment was evaluated. RESULTS The infection control time and Visual Analogue Scale score after treatment in the observation group were significantly lower than in the control group, respectively (P < 0.05). After the treatment, the serum levels of CRP, IL-6, IL-8, TNF-α, cortisol, epinephrine, norepinephrine, and glucose in each group were significantly lower than before the treatment (P < 0.05), and each index in observation was significantly lower than in the control group (P < 0.05). CONCLUSIONS In the treatment of open fractures complicated with soft tissue injury, cefazolin sodium pentahydrate combined with VSD can effectively reduce inflammation and stress, thus improving the treatment efficacy.

RESUMO OBJETIVO Investigar a eficácia clínica do cefazolin penta-hidrato de sódio combinado com drenagem por vedação a vácuo (VSD) no tratamento da fratura exposta complicada com lesão nos tecidos moles. MÉTODOS Sessenta e três doentes com fratura exposta complicada com lesões nos tecidos moles foram divididos em grupos de observação (n=33) e controle (n=30). Após redução cirúrgica, fixação e reparação da fratura, o grupo de controle foi tratado com VSD durante dez dias e o grupo de observação foi tratado com cefazolina penta-hidrato de sódio com base no VSD durante dez dias. O tempo de controle de infecção foi gravado. Após o tratamento, a dor dos doentes foi avaliada. Antes e após o tratamento, foram detectados os níveis séricos de proteína C-reativa (CRP), interleucina (IL)-6, IL -8, fator de necrose tumoral alfa (TNF-α), cortisol, epinefrina, norepinefrina e glicose. Após seis meses de tratamento, a taxa efetiva total de tratamento foi avaliada. RESULTADOS O tempo de controle da infecção e a pontuação da Escala Visual Analógica após o tratamento no grupo de observação foram significativamente inferiores ao do grupo de controle, respectivamente (P<0,05). Após o tratamento, os níveis séricos de CRP, IL-6, IL-8, TNF-α, cortisol, epinefrina, norepinefrina e glicose em cada grupo foram significativamente menores do que antes do tratamento, respectivamente (P<0,05), e cada índice de observação foi significativamente inferior ao do grupo de controle (P<0,05).

Introducción: Los pacientes que se presentan con cuadros de peritonitis de origen diverticular (estadios Hinchey III o IV) en un contexto de sepsis severa con inestabilidad hemodinámica (shock séptico) la realización de anastomosis primaria presenta una alta tasa de dehiscencia anastomótica y mortalidad operatoria, aconsejándose la realización de una resección y abocamiento a la manera de Hartmann. Sin embargo, la alta tasa de complicaciones relacionadas a la confección del ostoma, la complejidad de la cirugía de restauración del tránsito intestinal, asociado a que entre el 40 % y el 60 % de los Hartmann no se reconstruyen, ha estimulado a que se intenten otras variables de resolución para esta compleja y grave patología. Diversas publicaciones en los últimos años han propuesto la táctica de "cirugía del control del daño" con el objeto de disminuir la morbimortalidad de estos gravísimos cuadros sépticos y a su vez reducir la tasa de ostomías. El objetivo de este trabajo es presentar nuestra experiencia inicial con esta modalidad de manejo de la peritonitis diverticular Hinchey III/IV sepsis severa e inestabilidad hemodinámica (shock séptico) y realizar una revisión bibliográfica del tema. Material y método: Estudio observacional, descriptivo, de series de casos. Entre noviembre de 2015 y diciembre de 2016. Servicio de coloproctología del complejo médico hospitalario Churruca-Visca de la ciudad de Buenos Aires y práctica privada de los autores. Se utilizó la técnica de laparotomía abreviada y cierre temporal del abdomen mediante un sistema de presión negativa. Resultados: En el periodo descripto se operaron 17 pacientes con peritonitis generalizada purulenta o fecal de origen diverticular. Catorce casos fueron Hinchey III (82,36%) y 3 casos Hinchey IV (17,64%). En 3 casos se observó inestabilidad hemodinámica en el preoperatorio o intraoperatorio. Todos ellos correspondientes al estadio IV de Hinchey. Se describen los 3 casos tratados mediante esta táctica quirúrgica. Discusión: La alta tasa de morbimortalidad de este subgrupo de pacientes incentivó a diversos grupos quirúrgicos a implementar la técnica de control del daño, permitiendo de esta manera estabilizar a los pacientes hemodinámicamente y en un segundo tiempo evaluar la reconstrucción del tránsito intestinal. En concordancia con estas publicaciones, dos de nuestros pacientes operados con esta estrategia, pudieron ser anastomosados luego del segundo lavado abdominal. Conclusión: En pacientes con peritonitis diverticular severa asociado a shock séptico el concepto de laparotomía abreviada con control inicial del foco séptico, cierre temporal del abdomen con sistema de presión negativa y posterior evaluación de la reconstrucción del tránsito intestinal, es muy alentador. Permitiendo una disminución de la morbimortalidad como así también del número de ostomías. (AU)

Introduction: Patients presenting with diverticular peritonitis (Hinchey III or IV stages) in a context of severe sepsis with hemodynamic instability (septic shock), performing primary anastomosis has a high rate of dehiscence anastomotic and operative mortality, advising the realization of a resection and ostoma in the manner of Hartmann. However, the high rate of complications related to performing of ostoma, the complexity of intestinal transit restoration surgery, associated with the 40% to 60% of Hartmann reversal not performed, has encouraged other variables to be attempted resolution for this complex and serious pathology. Several publications in recent years have proposed the tactic of "damage control surgery" in order to reduce the morbidity of these serious septic charts while reducing the rate of ostomies. The objective of this study is to present our initial experience with this modality of management of the diverticular peritonitis Hinchey III/IV severe sepsis and hemodynamic instability (septic shock) and to carry out a bibliographic review of the subject. Material and method: Observational, descriptive study of case series. Between November 2015 and December 2016. Coloproctology service of the Churruca-Visca hospital medical complex in the city of Buenos Aires and private practice of the authors. The technique of abbreviated laparotomy and temporary closure of the abdomen was used by a negative pressure system. Results: In the period described, 17 patients with generalized purulent or fecal peritonitis of diverticular origin were operated. Fourteen cases were Hinchey III (82.36%) and 3 cases Hinchey IV (17.64%).In 3 cases, hemodynamic instability was observed in the preoperative or intraoperative period. all of them corresponding to Hinchey's Stage IV. The 3 cases treated using this surgical tactic are described. Discussion: The high morbidity rate of this subgroup of patients encouraged various surgical groups to implement the damage control technique, thus allowing patients to stabilize hemodynamically and in a second time evaluate reconstruction intestinal transit. In line with these publications, two of our patients operated on with this strategy could be anastomosated after the second abdominal wash. Conclusion: In patients with severe diverticular peritonitis associated with septic shock, the concept of abbreviated laparotomy with initial control of the septic focus, temporary closure of the abdomen with negative pressure system and subsequent evaluation of transit reconstruction intestinal, it's encouraging. Allowing a decrease in morbidity as well as the number of ostomies. (AU)

ABSTRACT Objective To describe the indications and contraindications of negative pressure assisted wound therapy as well as a modification to the negative pressure technique that has been shown to shorten the number of changes of dressings and hospital stay with the early closure of the wound. Methods A review of the existing literature in the databases OVID, PubMed, Cochrane and Medigraphic was carried out in relation to the pressure-assisted closure of wounds. This is a non-invasive and active healing system that uses localized and controlled negative pressure, which consists of a specialized dressing that includes reticulated foam that removes the exudates through a tube to an airtight container. This set forms microdeformations in the wound bed, which are known to cause an important increase in fibroblastic migration and consequently of higher quality tissue, granulation tissue formation and angiogenesis. Results It was found that this method shortens the number of days of hospital stay. The technique describes the primary closure of the wound after intense cleansing and debridement of the non-viable tissue and signs of infection. Conclusions Negative pressure wound therapy is effective for the treatment of deep infections in postsurgical spinal wound, with average time of use of 1 to 4 weeks in the most severe cases. Level of evidence IV; Case Series.

RESUMO Objetivo Descrever as indicações e contraindicações da terapia de cicatrização assistida pela pressão negativa, assim como uma modificação nessa técnica, que demonstrou diminuir o número de recargas de curativos e de internação hospitalar, por meio da manipulação do fechamento precoce de feridas. Métodos Foi realizada uma revisão da literatura, em bases de dados da OVID, PubMed, Cochrane e Medigraphic, sobre a terapia de cicatrização assistida pela pressão negativa. Este é um sistema ativo de cura não invasivo utilizando pressão negativa controlada e localizada, que consiste em um curativo especializado, com a inclusão de uma espuma reticulada que conduz, através de um tubo de exsudado, a um recipiente hermético, formando micro deformações no leito da ferida. A técnica tem provado ser uma importante causa do aumento da migração fibroblástica e, consequentemente, de tecido de qualidade mais elevada, junto com a formação de tecido de granulação e angiogénese. Resultados Em relação à técnica, descreve-se as etapas como forma de fechamento primário da ferida após limpeza intensa, desbridamento da área não viável e das características infecciosas. Além disso, o uso da técnica demonstrou diminuir o número de dias de internação hospitalar. Conclusão Este método de pressão negativa é eficaz para o tratamento de infecções pós-cirúrgicas profundas da coluna vertebral, sendo usado, em média, de um a quatro semanas nos casos mais graves. Nível de evidência IV; Série de Casos.
