Clinical ProblemHypergranulation tissue (HT) is granulation tissue that grows higher than the periwound skin level. HT can prevent epithelial cell migration and therefore inhibit wound healing.

The recognized causes of hypergranulation tissue include:

• unresolvedinflammation,asoccurswithchronicinfection

• highexudatelevelsandfluidasaresultofedema

• externalfriction

• foreignbodyirritant

• tooocclusiveofanenvironment

ManagementoftheunderlyingcauseiskeytoresolutionofHT.Previously,HTwasmanagedwithan antimicrobial barrier dressing. The approach was unsatisfactory because the dressing adhered tothewound,causing:a)traumaandpain;b)increasedproliferationofHT;c)woundtissuediscoloration,makingassessmentsdifficult;and,d)longer,morecomplicatedandexpensivewound clinic visits due the need to provide pre-dressing removal pain management and time required for adhered dressing removal.

4HTcasesarepresented;seechartfordetails.

Probable contributing causes of HT in these cases included:

• excesswoundmoistureassociatedwithedema

• woundinfection,amajorcauseofchronicwoundinflammation

• excessivewoundmoisture contributedby tissue edemacombinedwith ahydrogel andasecondary dressing used to enhance autolytic debridement

• acceleratedtissuegrowthpossiblyduetohighlyvasculartissue

All of the cases received previous unsuccessful treatments with advanced dressings or topical wound care products.

RationaleMultifunctional silver polymeric membrane dressings (SPMDs)* were chosen to manage the HT of all case studies. The dressings contain key components necessary for ideal wound healing. SPMDs are able to absorb 10 times their weight because the dressings contain a superabsorbent starch copolymer. The semipermeable film backing on the dressing allows for the appropriate moisturevaportransmissionrate(MVTR)whichbalancesthecorrectamountofgas(oxygenandcarbondioxide)exchangebetweenthewoundbedwiththeoutsideenvironment.SPMDscontain the same benefits as the polymeric membrane dressings plus the antimicrobial benefits of smallelementalsilvertohelpprotectthewoundsfrommicrobialcontamination.Inflammationistheresultoftissueinjuryeitherbytraumaorinresponsetoinfection,delayingwoundhealing.Polymericmembranedressings(PMDs)havebeenshowntoquiettheinflammatoryresponsebyreducingthespreadofmacrophagesandneutrophilstoareasofsecondaryinjurywithoutinterferingwithlocalinflammation,necessaryforhealing.Thedressingscontainanontoxicnonirritating cleanser that continually cleanses the wound. Glycerin keeps the wound bed moist while ensuring the dressing will not stick to the wound. SPMDs encourage autolysis by loosening the bonds between the slough and wound bed.

Clinical Treatment Approach Before and After SPMDMultifunctional SPMDs were utilized in two ways in managing HT: 1) HT was first destroyed with silver nitrate/cautery and then SPMD applied; 2) SPMD was begun without priorHT destruction. SPMDs were chosen for their antimicrobial benefits and their ability to prophylactically maintain low bio-burden. After HT was resolved SPMD or PMD was continued to closure.

The protocol at this facility is to cleanse wounds prior to dressing application to assist in the removal of debris and apply a barrier cream to the periwound skin as needed. The wounds for case1,2and4weresharpdebridedandpremedicatedasneededwithatopicalanaestheticduring the course of management.

Patient Outcomes

They found that SPMDs:

• maintainedoptimumwoundmoisture

• didnotadheretothewoundbed,sotherewasnotraumaorpainduringdressingchanges,whichin-turnreducedtheinflammatorycyclethat is a driving force of hypergranulation tissue formation

• reducedstimulationoftheHTformationprocess,accompaniedbyfaster wound healing and fewer clinic visits

Conclusions

NotonlydidSPMDprovideexcellentclinicaloutcomes,buttheclinicians and patients found the dressings’ use easy and convenient. SPMDs are now the standard of care at this facility for managing HT.

Objectives

1. Recognize that SPMDs are able to provide the appropriate absorbency conditions to maintain optimal healing while preventing adherence and enhance autolytic debridement.

2.DiscusshowSPMDshelptoinhibitandmanagewoundinfections.

3. Review the benefits of SPMDs which have been shown to inhibit the nociceptor response activity that is triggered during tissue trauma or aninfection,therebyhelpingtoreducewoundpain,andinflammationthroughout the wound management process.

CASE 4

14 days after the use of a calcium alginate dressing, the dressing adhered to the wound bed. To remove the dressing, it was necessary to debride the area and the calcium alginate dressing was discontinued. HT had been revealed with the debridement of necrotic tissue. HT developed on the wound at the mid left side of the wound at approx. 8-10 0’clock. Note: The red is raised exposed tissue. The wound measures: 7cm x 5.2cm x 0.2cm. Area- 36.4 cm². SPMD are initiated.

14 days after the application of SPMD dressings. HT eliminated and the wound is granulating.

Wound Measurement:7.0cm x 3.8cm x 0.1cmArea 26.6 cm²

Area of exposed bone-2.8cm x 2.4cm

Photo – 42 days later.

Wound is progressing towards closure.

HT developed from excessive moisture due to edema.

Wound Measurements:3cm x 2.2cm x 0.1cm Area- 6.6cm²

There is moderate amount of serosanguineous drainage with no odor. Wound bed with red granulation tissue.

SMPD was applied and secured with a 2-layer elastic wrap for compression.

23 days later the HT is eliminated.
