The healing process in acute wounds has been extensively studied and the knowledge derived from these studies has often been extrapolated to the care of chronic wounds, on the assumption that nonhealing chronic wounds were simply aberrations of the normal tissue repair process. However, this approach is less than satisfactory, as the chronic wound healing process differs in many important respects from that seen in acute wounds. In chronic wounds, the orderly sequence of events seen in acute wounds becomes disrupted or "stuck" at one or more of the different stages of wound healing. For the normal repair process to resume, the barrier to healing must be identified and removed through application of the correct techniques. It is important, therefore, to understand the molecular events that are involved in the wound healing process in order to select the most appropriate intervention. Wound bed preparation is the management of a wound in order to accelerate endogenous healing or to facilitate the effectiveness of other therapeutic measures. Experts in wound management consider that wound bed preparation is an important concept with significant potential as an educational tool in wound management.
This article was developed after a meeting of wound healing experts in June 2002 and is intended to provide an overview of the current status, role, and key elements of wound bed preparation. Readers will be able to examine the following issues;
• the current status of wound bed preparation;
• an analysis of the acute and chronic wound environments;
• how wound healing can take place in these environments;
• the role of wound bed preparation in the clinic;
• the clinical and cellular components of the wound bed preparation concept;
• a detailed analysis of the components of wound bed preparation.

Introduction
In 2001, in response to an overwhelming increase in patient visits for various pediatric abscesses, burns, and other wounds, an ambulatory burn and procedural sedation program (Pediatric Acute Wound Service, or PAWS) was developed to minimize operating room utilization. The purpose of this study is to report our initial 7-year experience with the PAWS program.Methods
The hospital records of all children managed through PAWS from 2001 to 2007 were reviewed. Outcomes measured include patient demographics, number and location of visits per patient, procedure information, cause of wounds, and reimbursement. χ2 test and linear regression were performed using GraphPad Prism (GraphPad Software Inc, San Diego, CA).Results
Overall, 7620 children (age 0-18 years) received wound care through PAWS from 2001 to 2007. There were no differences in patient age, race, and sex during this time period. Between 2001 and 2007, the percentage of patients seen as outpatients increased from 51% to 68% (P < .05), and the average number of visits per patient decreased from 3.9 to 2.4 (P = .05). In, 2007, 46% of the children required only 1 visit. In 2007, 74% of the visits were for management of wound and soft tissue infections, compared with only 9% in 2001 (P < .05). The contribution margin of a PAWS visit and total contribution margin in 2007 were $1052 and $4.0 million, respectively.Conclusion
The creation of PAWS has allowed for the transition in management of most pediatric skin and soft tissue wounds and infections to an independent ambulatory setting, alleviating the need for operating room resources, while functioning at a profitable cost margin for the hospital. 相似文献3.
Wound bed preparation has been performed for over two decades, and the concept is well accepted. The ‘TIME’ acronym, consisting of tissue debridement, infection or inflammation, moisture balance and edge effect, has assisted clinicians systematically in wound assessment and management. While the focus has usually been concentrated around the wound, the evolving concept of wound bed preparation promotes the treatment of the patient as a whole. This article discusses wound bed preparation and its clinical management components along with the principles of advanced wound care management at the present time. Management of tissue necrosis can be tailored according to the wound and local expertise. It ranges from simple to modern techniques like wet to dry dressing, enzymatic, biological and surgical debridement. Restoration of the bacterial balance is also an important element in managing chronic wounds that are critically colonized. Achieving a balance moist wound will hasten healing and correct biochemical imbalance by removing the excessive enzymes and growth factors. This can be achieved will multitude of dressing materials. The negative pressure wound therapy being one of the great breakthroughs. The progress and understanding on scientific basis of the wound bed preparation over the last two decades are discussed further in this article in the clinical perspectives.KEY WORDS: Chronic wound, negative pressure therapy, ulcer, wound, wound bed 相似文献

Management of chronic wounds has progressed from merely assessing the status of a wound to understanding the underlying molecular and cellular abnormalities that prevent the wound from healing. The concept of wound bed preparation has simultaneously evolved to provide a systematic approach to removing these barriers to natural healing and enhancing the effects of advanced therapies. This brief review of wound bed preparation traces the development of these concepts and explains how to apply systematic wound management using the TIME acronym - tissue (non viable or deficient), infection/inflammation, moisture (imbalance) and edge (non advancing or undermined). 相似文献

Wound management encompasses a number of disciplines. As new concepts and innovative technologies develop within this exciting field, it is important to share them in spite of the divergence of clinical perspectives between the expert disciplines. One such divergence exists between surgeons and nonsurgical wound specialists. As a result, there is a need to develop a common language between these two groups. How can we develop a common language that unites surgical expertise within medical wound management? One route may be through the principles of wound bed preparation, which we believe have great potential for the communication of effective surgical techniques. Another is through sharing our concepts of surgical debridement as it is applied to different wounds by a variety of surgical disciplines. In this monograph, we try to bring these two themes together. We discuss how wound bed preparation has added to our understanding of the pathophysiology of the nonhealing wound and has provided us with some general clinical concepts. We discuss what role debridement, and then specifically surgical debridement, has to play within wound bed preparation, before analyzing the importance of surgical debridement in tissue preservation and the control of infection. We finally look at ongoing work that examines the cost of various surgical debridement techniques. We will also review a new hydrosurgery system (VERSAJET®, Smith and Nephew, Hull, UK), which we believe has an important role to play in the surgical preparation of the wound. We also expect that this paper will remind our medical colleagues about the critical role played by surgery in wound management. 相似文献

The concept of wound bed preparation (WBP) heralded a new era in terms of how we treat wounds. It emphasized the difference between acute and chronic wounds, and it cemented the idea that the processes involved in the healing of acute wounds do not apply completely to the healing of chronic wounds. The arbitrary division of the normal healing process into the phases of hemostasis, inflammation, proliferation, and maturation addresses the events in acute wound healing. We have realized that the impediments to healing in chronic wounds lead to a failure to progress through these phases and are independent factors that make the chronic wound a much more complex condition. A major advance in resolving or addressing the chronic wound has been the concept of WBP. WBP allows us to address the problems of wound healing individually-the presence of necrotic tissue, hypoxia, high bacterial burden, corrupt matrix, and senescent cells within the wound bed. In WBP we can optimize our therapeutic agents to accelerate endogenous healing or to increase the effectiveness of advanced therapies. 相似文献

Our aging population has presented us with many new challenges. One such challenge is the need to manage an increase in wound-related problems effectively and efficiently. Over time, two parallel, yet divergent, management systems have developed. One strategy, used by medical specialists, uses a variety of dressings, topical enzymes, and local and systemic medications ultimately aimed at the promotion of healing by secondary intention or, in some cases, optimization of the wound for surgical reconstruction. In the second strategy, used by surgeons, early surgical intervention is used to prepare the wound for reconstruction in a timelier manner while promoting the healing process. This article reviews the development of these two distinct management systems and their areas of commonality and sets forth a new model to support the role of surgery in the treatment of problematic wounds. 相似文献

Wound bed preparation is the management of a wound in order to accelerate endogenous healing or to facilitate the effectiveness of split‐skin grafting. The formation of a healthy wound bed is a prerequisite to the use of advanced wound care products. Unless this is achieved, even the most sophisticated and expensive materials are unlikely to function correctly. An attempt has been made to use 3% citric acid ointment for wound bed preparation to prepare wound for grafting in five cases of wounds with large raw areas infected with multiple antibiotic‐resistant bacteria. 相似文献

Turner syndrome is a complex and common genetic disorder that affects women and is associated with a wide variety of anatomic and physiological disorders. These abnormalities, especially those relating to the airway and cardiovascular system, pose a challenge to the anesthesiologist. We report a case of Turner syndrome associated with mental retardation and difficult airway, followed by a discussion of the perioperative management and review of the relevant literature. We also provide a concise tabular summary of the many problems associated with Turner syndrome and give guidelines for a systematic perioperative approach. 相似文献

In the last few years, considerable progress has been made in the treatment of chronic ulcers, thanks to new therapy methods. Wound bed preparation is a modern approach for the removal of local barriers to healing by optimising debridement, reduction of bioburden and exudate management through the TIME principles, which have been introduced by the International Advisory Board on Wound Bed Preparation. However, this protocol does not evaluate the state of the repair process and therefore does not suggest the ideal therapeutic choice for each single patient. The revised TIME-H concept considers also the supposed healing time, H, and gives a score that correlates the wound condition with the incidental concomitance with medical pathologies related to the therapeutic measures, thus guiding the clinician towards a practical and systematic approach in the treatment. By applying this scheme to our situation, the average healing time was considerably reduced. The formulation of the new protocol TIME-H for a critical assessment of treatment scheme, which also includes the general conditions of the patient, represents a more rational and adequate approach for an accurate prognosis and therefore for a more suitable therapeutic choice in the treatment of difficult wounds. 相似文献

Treatment of hard-to-heal wounds involves a holistic approach for choosing between available treatment options. However, evidence for informing these choices is sparse, introducing uncertainty into decisions about the optimum treatment pathways that reflect the vast heterogeneity in this patient population. This paper discusses the existing clinical and health economic literature in order to provide insight into sources of uncertainty in the evaluation of the holistic approach to management of the hard-to-heal wounds, and how this uncertainty can be appropriately reflected in research. We identified three key sources of uncertainty in the evaluation of chronic wound treatments, namely heterogeneity in aetiology and patient populations, heterogeneity in treatment pathways, and challenges around capturing all relevant outcomes. Reflecting these complexities requires sophisticated modelling of treatment sequencing and long-term outcomes. The paper discusses how the scope specification, scenario analyses, and sensitivity analyses can be used to fully characterise analytical uncertainty. 相似文献

Irreversible facial palsy (IFP) presents a multitude of problems arising from a paretic periorbital and facial complex, the solutions to which cross the spectrum of multiple specialties. The process of facial rehabilitation can be simplified by subdividing the face into functional units. These units consist of the brow complex, the periorbital complex, the midface complex, and the lower face/oral complex. Although all of these units are interrelated and influence each other, careful study of the deformity and symptoms of each unit yields a coherent approach and customized surgical plan. The following provides a complete evaluation method for the surgeon to review and customize an approach to the individual patient's needs and desires. Facial rehabilitation must be tailored to each individual, addressing both functional as well as aesthetic concerns for each facial unit. 相似文献
