Wound irrigation techniques: new Steripod normal saline

Clinical use of 0.1% polyhexanide and propylbetaine on acute and hard-to-heal wounds: a literature review

OBJECTIVE

To summarise the findings on the effect of the clinical use of 0.1% polyhexanide-propylbetaine (PHMB/betaine) solution/gel on acute and hard-to-heal (chronic) wound healing.

METHOD

A literature search was conducted in MEDLINE, CINAHL, Embase, Scopus and the CENTRAL Trials Registry of the Cochrane Collaboration. Paired reviewers conducted title and abstract screening and full-text screening to identify experimental, quasi-experimental and observational studies. Study quality and risk of bias were not formally evaluated.

RESULTS

A total of 17 studies met the eligibility criteria. The findings from 12 studies indicated that the use of 0.1% PHMB/betaine solution/gel had: a low risk of contact sensitivity; could help debridement during wound cleansing; aided effective wound bed preparation; reduced wound size, odour and exudate; improved pain control; reduced microbial load; and enhanced wound healing. The results of three studies indicated that both 0.1% PHMB and saline solution were effective in reducing bacterial load, while another showed that adding 0.1% PHMB to tie-over dressings had no effect on reducing bacterial loads in wounds. Another study concluded that disinfection and granulation of pressure ulcers with hydrobalance dressing with 0.3% PHMB was faster and more effective than using 0.1% PHMB/betaine.

CONCLUSION

The findings of this literature review showed that 0.1% PHMB/betaine solution/gel appeared to be useful and safe for wound cleansing, was effective in removing soft debris and slough from the wound bed, and created a wound environment optimal for healing. Although these actions cannot be attributed solely to this treatment modality, these results do highlight the unique action of this combined product. However, more robust studies are needed to confirm these results.

Wound cleansing for treating venous leg ulcers

BACKGROUND

Leg ulcers are open skin wounds that occur below the knee but above the foot. The majority of leg ulcers are venous in origin, occurring as a result of venous insufficiency, where the flow of blood through the veins is impaired; they commonly arise due to blood clots and varicose veins. Compression therapy, using bandages or stockings, is the primary treatment for venous leg ulcers. Wound cleansing can be used to remove surface contaminants, bacteria, dead tissue and excess wound fluid from the wound bed and surrounding skin, however, there is uncertainty regarding the effectiveness of cleansing and the best method or solution to use.

OBJECTIVES

To assess the effects of wound cleansing, wound cleansing solutions and wound cleansing techniques for treating venous leg ulcers.

SEARCH METHODS

In September 2019 we searched the Cochrane Wounds Specialised Register; the Cochrane Central Register of Controlled Trials (CENTRAL); Ovid MEDLINE (including In-Process & Other Non-Indexed Citations); Ovid Embase and EBSCO CINAHL Plus. We also searched clinical trials registries for ongoing and unpublished studies, and scanned reference lists of relevant included studies as well as reviews, meta-analyses and health technology reports to identify additional studies. There were no restrictions with respect to language, date of publication or study setting.

SELECTION CRITERIA

We considered randomised controlled trials (RCTs) comparing wound cleansing with no wound cleansing, or RCTs comparing different wound cleansing solutions, or different wound cleansing techniques.

DATA COLLECTION AND ANALYSIS

We screened studies for their appropriateness for inclusion, assessed their risk of bias using the Cochrane 'Risk of bias' tool, and used GRADE methodology to determine the certainty of evidence. Two review authors undertook these tasks independently, using predetermined criteria. We contacted study authors for missing data where possible.

MAIN RESULTS

We included four studies with a total of 254 participants. All studies included comparisons between different types of cleansing solutions, and three of these reported our primary outcomes of complete wound healing or change in ulcer size over time, or both. Two studies reported the secondary outcome, pain. One study (27 participants), which compared polyhexamethylene biguanide (PHMB) solution with saline solution for cleansing venous leg ulcers, did not report any of the review's primary or secondary outcomes. We did not identify any studies that compared cleansing with no cleansing, or that explored comparisons between different cleansing techniques. One study (61 participants) compared aqueous oxygen peroxide with sterile water. We are uncertain whether aqueous oxygen peroxide makes any difference to the number of wounds completely healed after 12 months of follow-up (risk ratio (RR) 1.88, 95% confidence interval (CI) 1.10 to 3.20). Similarly, we are uncertain whether aqueous oxygen peroxide makes any difference to change in ulcer size after eight weeks of follow-up (mean difference (MD) -1.38 cm², 95% CI -4.35 to 1.59 cm²). Finally, we are uncertain whether aqueous oxygen peroxide makes any difference to pain reduction, assessed after eight weeks of follow-up using a 0 to 100 pain rating, (MD 3.80, 95% CI -10.83 to 18.43). The evidence for these outcomes is of very low certainty (we downgraded for study limitations and imprecision; for the pain outcome we also downgraded for indirectness). Another study (40 participants) compared propyl betaine and polihexanide with a saline solution. The authors did not present the raw data in the study report so we were unable to conduct independent statistical analysis of the data. We are uncertain whether propyl betaine and polihexanide make any difference to the number of wounds completely healed, change in ulcer size over time, or wound pain reduction. The evidence is of very low certainty (we downgraded for study limitations and imprecision). The final study (126 participants) compared octenidine dihydrochloride/phenoxyethanol (OHP) with Ringer's solution. We are uncertain whether OHP makes any difference to the number of wounds healed (RR 0.96, 95% CI 0.53 to 1.72) or to the change in ulcer size over time (we were unable to conduct independent statistical analysis of available data). The evidence is of very low certainty (we downgraded for study limitations and imprecision). None of the studies reported patient preference, ease of use of the method of cleansing, cost or health-related quality of life. In one study comparing propyl betaine and polihexanide with saline solution the authors do not report any adverse events occurring. We are uncertain whether OHP makes any difference to the number of adverse events compared with Ringer's solution (RR 0.58, 95% CI 0.29 to 1.14). The evidence is of very low certainty (we downgraded for study limitations and imprecision).

AUTHORS' CONCLUSIONS

There is currently a lack of RCT evidence to guide decision making about the effectiveness of wound cleansing compared with no cleansing and the optimal approaches to cleansing of venous leg ulcers. From the four studies identified, there is insufficient evidence to demonstrate whether the use of PHMB solution compared with saline solution; aqueous oxygen peroxide compared with sterile water; propyl betaine and polihexanide compared with a saline solution; or OHP compared with Ringer's solution makes any difference in the treatment of venous leg ulcers. Evidence from three of the studies is of very low certainty, due to study limitations and imprecision. One study did not present data for the primary or secondary outcomes. Further well-designed studies that address important clinical, quality of life and economic outcomes may be important, based on the clinical and patient priority of this uncertainty.

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.

Infection control and intravenous therapy in patients in the community

Recent efforts to reduce infections have been focused within the hospital setting. Early hospital discharge, shorter inpatient stays, day surgery and the movement of patients between acute and long-stay care facilities is likely to make community-acquired infection an increasing problem. There are, or course, universal precautions and general infection control issues to consider when undertaking any clinical procedure, both in hospital and the community, but when administering intravenous therapy (medicines and/or maintenance fluids) specific measures need to be considered. This is especially important if a patient is receiving intravenous therapy at home. There are many reasons why patients may need to receive intravenous therapy in the community and these will all present with specific problems. This paper will discuss some of the infection control procedures one must undertake when administering intravenous therapy to patients in the community.

Infection control and IV therapy in patients with Clostridium difficile

Clostridium difficile is a spore-forming anaerobe belonging to the family Clostridium, with the bacteria being found in low numbers in approximately 5% of the healthy adult population. Together with meticillin-resistant Staphylococcus aureus, it is a major healthcare-associated infection and is responsible for considerable morbidity and mortality. Antibiotics administered to patients can alter normal gut flora, allowing the proliferation of C. difficile and causing antibiotic-associated diarrhoea and colitis. Such diarrhoea, if severe, can lead to dangerous dehydration and even hypovolaemia, especially in the elderly. To limit the physiological impact of diarrhoea, it is sometimes necessary to administer intravenous therapy. Although good clinical practice demands that infection control should be considered in all clinical situations, specific infection control procedures need to be adhered to when administering intravenous therapy to patients with C. difficile.

Aseptic technique: evidence-based approach for patient safety

The fact that there is a relationship between the standards of aseptic technique performance and the rise in hospital infection rates has been suggested by the Department of Heath's (DoH's, 2004) 'Winning Ways' document. This literature review considers how the aseptic technique is performed in the UK, and examines the nature of ritualistic and evidence-based practice underpinning this skill-based procedure. The findings have identified an emerging glove culture and continuing poor hand-hygiene practices. The alternative 'clean technique' is also adopted widely in clinical practice which confuses the aseptic theory-practice gap. While it is hard to pinpoint an actual time or event that causes infection, it is unlikely nurses will ever become involved in litigation as a result of a poorly performed aseptic technique. However, the review concludes that nurses should not become too complacent. It briefly considers how performance of the aseptic technique can be improved, through creative educational strategy, applied risk assessment and clinical audits of nurses' practices.

A case study of holistic wound management in intensive care

Complex wounds that have become contaminated after abdominal surgery can cause a great deal of distress to patients, and the management of such wounds requires an holistic and humanistic approach (Torrance, 1985). This case study aims to address the issues of wound management, involving some of the underlying and surrounding problems - exudate, malodour, nutrition and wound pain - that may be associated with chronic wounds after surgery. Further discussed will be the treatment and use of vacuum-assisted closure (VAC) therapy which was administered to the patient in this study. The clinical environment is an intensive care unit (ICU) within a district general hospital. The critical care nurse is primarily involved in caring for resuscitation of the critically ill patient and wound care is often a long way down the list of priorities; however, wound management is important and must be addressed at part of holistic nursing care.

Applying the principles of infection control to wound care

Human skin in healthy adults is inhospitable organisms. A wound may occur from any accidental or deliberate trauma that breaks the surface of the skin. Once this line of defence is broken there is a risk of infection. All soft tissue injuries, whether chronic, traumatic or surgical, involve the same basic biochemical and cellular processes. This article looks at the risk factors associated with healing of such wounds. The principles of asepsis, wound cleansing agents, choice of dressings and the taking of wound swabs are considered.

The use of Askina saline in the wound cleansing process

After the removal of a dressing from a wound, wound cleansing is often the first action to be taken by the nurse. Saline or tap water is often used to loosen the dressing and therefore help to remove it. It can also be used for the subsequent cleansing of the wound if required. B/Braun Medical has a range of modern wound care products for all healing phases of acute and chronic wounds and this article will look at their saline range.
