Topical antimicrobial prophylaxis in minor wounds

Effect of topical antibiotics on the prevention and management of wound infections: A meta-analysis

A meta-analysis research was implemented to appraise the effect of topical antibiotics (TAs) on the prevention and management of wound infections (WIs). Inclusive literature research was performed until April 2023, and 765 interconnected researches were reviewed. The 11 selected researches included 6500 persons with uncomplicated wounds at the starting point of the research: 2724 of them were utilising TAs, 3318 were utilising placebo and 458 were utilising antiseptics. Odds ratio (OR) and 95% confidence intervals (CIs) were utilised to appraise the consequence of TAs on the prevention and management of WIs by the dichotomous approach and a fixed or random model. TAs had significantly lower WI compared with placebo (OR, 0.59; 95% CI, 0.38-0.92, p = 0.02) and compared with antiseptics (OR, 0.52; 95% CI, 0.31-0.88, p = 0.01) in persons with uncomplicated wounds (UWs). TAs had significantly lower WIs compared with placebo and antiseptics in persons with UWs. However, caution needs to be taken when interacting with their values because of the low sample size of some of the chosen researches and low number of researches found for the comparisons in the meta-analysis.

Recent technological advances in the management of chronic wounds: A literature review

Background

Wound treatment comprises a substantial portion of the healthcare budgets in developed countries. Studies suggest that about 50% of patients admitted to hospitals have wounds, while 1%−2% of the general population in the developed world suffers from chronic wounds. Chronic wounds fail to repair themselves within the expected period of 30 days. Technologies have been developed to address challenges encountered during wound care with the aim of alleviating pain, promoting healing, or controlling wound infections.

Objective

The objective of this study was to explore the technological improvements that have been made in this field over time.

Methods

To gain insight into the future of wound management, a systematic review of literature on the subject was conducted in scientific databases (PubMed, Scopus, Web of Science, Medline, and Clinical Trials).

Results and Discussion

Results indicate that wound dressings have evolved from the traditional cotton gauze to composite materials embedded with appropriate ingredients such as metal‐based nanoparticles. Studies on biodegradable dressing materials are also underway to explore their applicability in dressing large and irregular wounds. On the other hand, conventional drugs and traditional formulations for the management of pain, inflammation, infections, and accelerating healing have been developed. However, more research needs to be carried out to address the issue of microbial resistance to drugs. Drugs for managing other ailments also need to be designed in such a way that they can augment wound healing. In addition, it has been demonstrated that a coordinated integration of conventional and traditional medicine can produce laudable results in chronic wound management.

Conclusion

Accordingly, collaborative efforts and ingenuity of all players in the field can accelerate technological advances in the wound care market to the benefit of the patients.

Wounds affect about 50% of patients admitted to hospitals.

Technologies have been developed including biodegradable dressing materials to address underlying challenges.

Technological advancement, rising incidences of chronic wounds, growing government support, and a rising elderly population will drive wound market growth.

A careful combination of recent research outputs can greatly change wound care technologies.

This review highlights the recent research advances and opportunities in the wound care field.

The future lies in biodegradable dressing materials, probably embedded with selected nanoparticles and which shall be combined in predetermined ratios.

A systematic review and meta-analysis on the use of prophylactic topical antibiotics for the prevention of uncomplicated wound infections

Background

The prescription of topical antibiotics for the prevention of infections in uncomplicated wounds is common. However, the efficacy is not well reported. Therefore, the objective of the study was to conduct a systematic review and meta-analysis of the available evidence on prevention of uncomplicated wound infections by prophylactic topical antibiotics.

Materials and methods

The search included Pubmed, Google Scholar, SCOPUS, Embase, Cochrane, ClinicalTrials.gov, International Clinical Trials Registry Platform, National Technical Information Service, and the National Guidelines Clearinghouse.

Results

We identified eight randomized controlled trials and four quasi-randomized trials that met the criteria for the systematic review. Of these trials, 11 studies were pooled for meta-analysis to compare the effects of topical antibiotics versus placebo and 4 studies were pooled for comparison of effects of topical antibiotics versus topical antiseptics on uncomplicated wounds. Fewer wound infections occurred in the topical antibiotic arms compared to placebo (pooled risk ratio: 0.57 [95% CI: 0.37 to 0.86]; p=0.01 and pooled risk difference: −3.1% [95% CI: −5.8% to −0.34%]; p=0.03). Compared to antiseptics, topical antibiotics demonstrated statistically significant relative risk reduction (pooled risk ratio: 0.56 [95% CI: 0.23 to 0.91]; p=0.02), while there was no significant absolute risk reduction (pooled risk difference: −3.7% [95% CI: −7.9% to +0.6%]; p=0.09).

Conclusion

Topical antibiotics are effective in reducing wound infections after surgical procedures, but the absolute benefit is small. Given the global emergence of antimicrobial resistance, judicious use of antibiotics is encouraged and use of antiseptics should be considered as a reasonable alternative to topical antibiotics.

Chronic Wound Healing: A Review of Current Management and Treatments

Wound healing is a complex, highly regulated process that is critical in maintaining the barrier function of skin. With numerous disease processes, the cascade of events involved in wound healing can be affected, resulting in chronic, non-healing wounds that subject the patient to significant discomfort and distress while draining the medical system of an enormous amount of resources. The healing of a superficial wound requires many factors to work in concert, and wound dressings and treatments have evolved considerably to address possible barriers to wound healing, ranging from infection to hypoxia. Even optimally, wound tissue never reaches its pre-injured strength and multiple aberrant healing states can result in chronic non-healing wounds. This article will review wound healing physiology and discuss current approaches for treating a wound.

National Athletic Trainers' Association Position Statement: Management of Acute Skin Trauma

OBJECTIVE

  To present recommendations for the cleansing, debridement, dressing, and monitoring of acute skin trauma in patients.

BACKGROUND

  Acute skin trauma is common during participation in athletic and recreational activities. Clinical decisions and intervention protocols after injury vary among athletic trainers and are often based on ritualistic practices. An understanding of cleansing, debridement, and dressing techniques; clinical features of infection and adverse reactions; and monitoring of acute skin trauma is critical for certified athletic trainers and other allied health and medical professionals to create a local wound environment that promotes healing and lessens the risk of complications.

RECOMMENDATIONS

  These guidelines are intended to provide the certified athletic trainer and others participating in athletic health care with specific knowledge about and recommendations for the management of acute skin trauma.

A Randomized Controlled Study to Compare Conventional and Evidence Based Treatment Protocols in Fresh Compound Fractures

INTRODUCTION

A recent concept review in Journal of Bone and Joint Surgery (JBJS) outlines evidence to control peri-operative infections in compound fractures. However, evidence for impact of adopting a protocol combining measures that have some evidence is lacking in literature. The present method of treatment at King George's Medical University (KGMU) is representative of the conventional practice of managing compound fractures in India and is an appropriate control for trial against the Experimental Evidence Based Protocol (EBP).

AIM

To study the additional impact of adopting Evidence Based Protocol on parameters defining infection rate and bone union.

MATERIALS AND METHODS

This randomized controlled study was conducted at the orthopaedics department of KGMU. Two hundred and twenty six patients of compound fractures of both bone leg, age > 12y were randomized to two groups. One group received standard treatment and the experimental group received treatment as per JBJS review.

STATISTICAL ANALYSIS

Random allocation was tested by comparing baseline characteristics of the two groups. The two groups were compared for all the outcome variables in terms of time to a negative wound culture, time to wound healing, time to union at fracture site and time to achieve complete range of motion at knee joint.

RESULTS

Random allocation was successful. EBP group reported significantly lesser time to a negative culture report from wound (mean in conventional=4.619, experimental=1.9146, p=0.0006), lesser time to bony union (mean in conventional=23.8427 weeks, experimental=22.8125 weeks, p=0.0027), lesser time to wound healing (mean in conventional=14.4425 weeks experimental=10.4513 weeks, p=0.0032), and a lesser duration of hospital stay (mean in conventional=6.5982 days, experimental=4.5000 days, p=0.0343).

CONCLUSION

EBP based on the guidelines suggested by Fletcher et al., significantly shorten the time taken for achieving a negative culture and hasten wound and fracture healing. Therefore EBP is recommended for use in settings like the KGMU trauma center.

Wound healing potential of formulated extract from hibiscus sabdariffa calyx

Wound healing agents support the natural healing process, reduce trauma and likelihood of secondary infections and hasten wound closure. The wound healing activities of water in oil cream of the methanol extract of Hibiscus sabdariffa L. (Malvaceae) was evaluated in rats with superficial skin excision wounds. Antibacterial activities against Pseudomonas aeroginosa, Staphylococcus aureus and Echerichia coli were determined. The total flavonoid content, antioxidant properties and thin layer chromatographic fingerprints of the extract were also evaluated. The extract demonstrated antioxidant properties with a total flavonoid content of 12.30±0.09 mg/g. Six reproducible spots were obtained using methanol:water (95:5) as the mobile phase. The extract showed no antimicrobial activity on the selected microorganisms, which are known to infect and retard wound healing. Creams containing H. sabdariffa extract showed significant (P<0.05) and concentration dependent wound healing activities. There was also evidence of synergism with creams containing a combination of gentamicin and H. sabdariffa extract. This study, thus, provides evidence of the wound healing potentials of the formulated extract of the calyces of H. sabdariffa and synergism when co-formulated with gentamicin.

Topical antibacterial agents

Decreased systemic toxicity, ease of application, and increased concentrations at the target site are some of the important advantages topical antibacterial agents offer. This article reviews the literature on selected indications for these agents and provides in-depth examination of specific agents for the prophylaxis and treatment of skin and wound infections.

A comparison of postprocedural wound care treatments: do antibiotic-based ointments improve outcomes?

BACKGROUND

Topical antibiotic ointments are commonly used for the postprocedural treatment of superficial wounds created during dermatologic procedures. We propose that antibiotics may not be necessary for healing these wounds, have the potential to cause allergic contact dermatitis, and may contribute to the development of antibiotic resistance.

OBJECTIVE

We sought to compare the efficacy and safety of a nonantibiotic, petrolatum-based ointment (Aquaphor Healing Ointment [AHO], Beiersdorf Inc, Wilton, CT) and an antibiotic-based first-aid ointment (Polysporin [Poly/Bac], Johnson & Johnson, New Brunswick, NJ) for the treatment of wounds created by removal of seborrheic keratoses.

METHODS

In this double-blind study, 30 subjects each had two seborrheic keratoses removed from their trunk or abdomen; one wound was treated with AHO and one with Poly/Bac twice daily. Clinical grading of wound healing and subjective irritation was assessed at days 7, 14, and 28 postwounding. Adverse events were recorded.

RESULTS

Clinical grading assessment showed no differences between wounds treated with AHO versus Poly/Bac for erythema, edema, epithelial confluence, crusting, and scabbing at any time point. Subjective irritation assessment showed wounds treated with Poly/Bac had a significant increase in burning at week 1, whereas no differences were seen between treatments for stinging, itching, tightness, tingling, or pain. One case of allergic contact dermatitis was reported after Poly/Bac treatment.

LIMITATIONS

This was a relatively small study.

CONCLUSIONS

This study demonstrated that the petrolatum-based skin protectant ointment AHO provided equivalent efficacy for wound healing as a combination antibiotic first-aid ointment. Antibiotics may not be necessary to achieve satisfactory wound healing and may cause allergic contact dermatitis.

Topical Application of Bacitracin Ointment Is Associated with Decreased Risk of Mediastinitis after Median Sternotomy

BACKGROUND

The diagnosis of mediastinitis after open-heart surgery is infrequent but dreaded as it carries a high morbidity and mortality. The purpose of this study was to investigate the impact that topical antibacterials would have on the postoperative mediastinitis rate.

METHODS

Data were collected from 2455 consecutive patients who underwent sternotomy and cardiopulmonary bypass for both valvar and ischemic heart disease. Prior to 1999, patients (n = 1036) underwent surgery with standard perioperative intravenous antibiotics but no application of bacitracin. After 1999, patients (n = 1419) underwent surgery with intravenous antibiotics and application of bacitracin ointment to the sternotomy incision after closure.

RESULTS

Cases of mediastinitis occurred in 12 patients (1.2%) not treated with bacitracin, which required re-exploration, sternectomy, and soft tissue closure of the mediastinum. Alternatively, 3 patients (0.2%) in the group treated with bacitracin developed mediastinitis (P < .01). Therefore, the use of topical antibacterials was associated with a 6-fold reduction in the risk of mediastinitis after cardiac surgery. This significant difference in the infection rate was observed even though the percentage of patients with risk factors for mediastinitis was equal to greater than the group not treated with bacitracin. Non-bacitracin versus bacitracin: diabetics, 298 versus 484; emergency operations, 24 versus 50; bilateral internal thoracic grafts, 28 versus 29; and obesity (body mass index >30), 294 versus 396.

CONCLUSIONS

The use of topical antibacterials is associated with a decrease in the risk of mediastinitis after cardiac surgery.

Update on the Use of Antibiotics in Cutaneous Surgery

BACKGROUND

Antibiotics are often prescribed in perioperative settings, including dermatologic surgery. Given the continued evolution in the breadth and complexity of cutaneous procedures performed and inevitable localized or distant infections that occasionally occur, it seems prudent to periodically evaluate findings and recommendations from the literature regarding the use of antibiotics in cutaneous surgery.

MATERIALS AND METHODS

Literature review from English-language sources from the past 30 years, especially focusing on sources from the past 5 to 10 years. Data were examined for a variety of cutaneous surgical procedures, routes of antibiotic administration, and consideration of both cutaneous and distant infections.

RESULTS

The literature suggests that, for most routine skin procedures, antibiotic use is probably not warranted for the prevention of surgical wound infection, endocarditis, and late prosthetic joint infections. During prolonged Mohs procedures, delayed repairs, grafts, takedowns of interpolation flaps, or any procedure that breaches a mucosal surface, the evidence is less clear, and decisions should be made on a case-by-case basis. Topical antibiotics are probably overused, although silver sulfadiazine may have an undeserved negative reputation among dermatologists. Systemic prophylactic antibiotics for laser resurfacing and liposuction appear not to be routinely necessary, although patients with known prior herpes infection likely should receive antiviral prophylaxis. The overall reported infection rates and infectious complications remain low in dermatologic surgery, and antibiotic therapy may be prescribed excessively or inappropriately as a result. CONCLUSION.: Antibiotics continue to be widely used, and through varying routes of administration, in the setting of dermatologic surgery. Prudent use of these agents is indicated in high-risk patients, certain anatomic locations, and the presence of overt infection. Additional studies may help clarify the most appropriate indications, and in which patient populations, in the future.

A prospective, randomized pilot evaluation of topical triple antibiotic versus mupirocin for the prevention of uncomplicated soft tissue wound infection

Little data exists comparing the safety and efficacy of triple antibiotic ointment (TAO) and mupirocin for prevention of uncomplicated soft tissue wound infections. The purpose of this investigation was to conduct a pilot study of the relative safety, efficacy, and cost effectiveness of the 2 preparations. This was a randomized, prospective, interventional study to determine the difference in infection rates of uncomplicated soft tissue wounds between subjects treated with TAO and mupirocin ointment after standard wound care and suturing. Subjects were enrolled at presentation to the ED if they met the study inclusion criteria and were required to make one follow-up visit to the ED to determine the status of their wound (infected vs. not infected). A total of 99 patients were enrolled and assessed at the follow-up visit. The groups had similar rates of self-reported compliance with wound care and dressing changes. Patients in the mupirocin group had a greater rate of signs of infection (12% vs. 6.1%), and infection (4% vs. 0%) compared with patients in the TAO group, although neither difference achieved statistical significance. There were no serious adverse effects in either group. This pilot study found a similar rate of wound infection and adverse events between TAO and mupirocin ointments. Results should be confirmed in a larger equivalency trial.

Topical antibacterial agents

Topical antibacterial agents occupy an important niche of antimicrobial therapy for both inpatients and outpatients. These agents, including antiseptic and antibiotic preparations, are used for prophylaxis and treatment of infection. Prophylactic uses include application for traumatic and surgical wounds, burns, intravascular catheters, and eradication of S. aureus nasal carriage. Topical antibacterial agents are also used for treatment of primary and secondary pyodermas. Individual antibacterial agents have been reviewed. Of note, despite the widespread use of topical antibacterial agents, further data on which to guide therapy are needed in many instances.
