Hydrogels in wound care
Hydrogel wound dressings aid in the healing process by providing a moist environment and non-adherent pain relief. Discover how hydrogel dressing wound care changes the game for a wide range of acute and chronic wounds, including infected wounds. Its composition of 90% water in a cool, soothing gel effectively regulates fluid exchange.
What Are Hydrogels?
A hydrogel is a natural or synthetic polymer material that can absorb and retain a large amount of liquid. Natural hydrogels, like collagen and alginate, exhibit great variation and are often combined with synthetic hydrogels to create composite polymers that manifest greater stability. Because of their responsive and programmable qualities, hydrogels are widely used in robotics, chemical detectors and biomedical applications. These polymers can take the form of amorphous gels or be impregnated into medical pads or wound fillers.
Hydrogels for Wound Healing
The process of wound healing requires a clean, moist environment and time. If you’re stumped looking for reasons a chronic wound won’t heal, the type of dressing applied may well be the culprit. Traditional wound care, like gauze, pulls moisture from the wound bed and can adhere to the wound, causing undue pain during dressing changes. Hydrogel wound care, on the other hand, donates moisture to the wound, creating a moist environment that promotes autolytic debridement, granulation and epithelialization. Non-adherent hydrogel wound dressings are indicated for:
- Dry or slightly moist partial- and full-thickness wounds
- Abrasions and partial-thickness burns
- Granulating wounds
- Skin damage from radiation
- Wounds with slough or eschar
Do not choose hydrogel for wounds with very high exudate or for full-thickness burns.
How to Choose a Hydrogel Wound Dressing
When it comes to choosing a hydrogel dressing, wound care best practices are an appropriate guide. Select a hydrogel wound dressing that will accommodate the specific character and severity of your patient’s wound while keeping a few cautions in mind:
- All hydrogel wound dressings require a secondary dressing.
- Do not use hydrogel wound care in conjunction with foams, gelling fiber dressings or additional, non-impregnated alginates.
Take care to avoid maceration on periwound tissue and use a plain saline solution to clean the wound between dressing changes. To help reduce the pain of radiation burns, chill hydrogel wound dressing pads in the refrigerator and apply them cold for a soothing experience.
Hydrogel Wound Gels, Pads and Fillers
In addition to hydrogel pads, many trusted brands of hydrogel wound gels and hydrogel fillers are available to patients and caregivers. Triad, SilvaSorb and Anasept are popular options for antimicrobial hydrogel wound care, while MANUKApli Sterile Honey Wound Dressing harnesses the purest medical-grade Manuka honey to act as a 100% natural, antibiotic-free hydrogel for wound healing. Regenecare HA is a hydrogel wound gel that delivers 2% lidocaine to reduce pain and inflammation immediately, in addition to aloe vera and marine collagen to rebuild the skin matrix and restore an effective moisture barrier.

Orlando officials condemn removal of rainbow crosswalk near Pulse nightclub mass shooting site as a ‘cruel political act’
[url=https://lawdnepr.dp.ua/]юрист Запорожье[/url]
Orlando officials on Thursday condemned the state’s overnight removal of a rainbow crosswalk outside the Pulse nightclub – a commemoration of the 49 people killed at the LGBTQ-friendly nightclub in 2016.
Painting over one of the most important landmarks of the state’s LGBTQ community is part of a larger attack on LGBTQ people by Gov. Ron DeSantis and his administration, officials say.

Orlando Mayor Buddy Dyer said he was “devastated” by the removal of the Pulse memorial crosswalk.
“This callous action of hastily removing part of a memorial to what was at the time our nation’s largest mass shooting, without any supporting safety or discussion, is a cruel political act,” Dyer said in a post on X.
The crosswalk was installed by the state in 2017 and adheres to national safety standards, Dyer added. The colorful crosswalk added visibility, making it safer for the large number of visitors to the memorial, he said.
CNN has reached out to the Florida Department of Transportation for comment.

The removal comes only two months after the city marked the nine-year anniversary of the Pulse tragedy. On June 12, 2016, a gunman opened fire at the popular gay nightclub, making it the worst mass shooting in modern US history at the time.

The removal also comes during campaigns by the state and Trump administration to paint over “asphalt art,” including rainbow crosswalks. The dual directives are calling this a safety measure to make roads easier to navigate without distractions.
In June, the Florida Department of Transportation issued a memo prohibiting crosswalk markings and pavement surface art “associated with social, political, or ideological messages or images and does not serve the purpose of traffic control.”
The following month, US Transportation Secretary Sean Duffy sent a letter to governors of all 50 states saying intersections and crosswalks should be “kept free from distractions.”
“Taxpayers expect their dollars to fund safe streets, not rainbow crosswalks,” Duffy said about the letter in an X post on July 1. “Political banners have no place on public roads. I’m reminding recipients of USDOT roadway funding that it’s limited to features advancing safety, and nothing else.”

Cracker Barrel’s modern makeover doesn’t stop with redoing its restaurants. It’s dropping the barrel and the man from its logo, too.
On Tuesday, the Southern-inspired casual dining chain unveiled a new logo “rooted even more closely to the iconic barrel shape,” but without the barrel itself — a central part of the brand’s identity since 1977. (As for the the barrel itself, it was “essentially the water coolers of the day,” Cracker Barrel explained in a blog post.)

The identity refresh also includes new TV commercials, a redesigned menu and several new fall-themed foods, part of a larger $700 million transformation plan to shake off its stodgy image and lure in new diners.
“The way we communicate, the things on the menu, the way the stores look and feel … all of these things came up time and time again in our research as opportunities for us to really regain relevancy,” said CEO Julie Felss Masino in 2024.

In particular, the new logo is the latest in a string of changes angering some of its loyal fans who fear the 56-year-old chain is drifting too far from its bucolic roots. On social media, some users griped, with one writing that the “changing the logo just feels like another little piece of culture dying off.” The change also angered some conservatives, too, like President Donald Trump’s son.
Cracker Barrel has also been remodeling some of its 660-plus restaurants. The chain has “decluttered” the interiors by removing the country-themed trinkets that lined the walls and lightened up the interiors, shifting away from the dark woods. So far, reaction has been mixed on social media, with some videos on TikTok going viral voicing their displeasure.
Masino remains adamant that the renovations are working, telling ABC News this week that “people like what we’re doing” and that feedback has been “overwhelmingly positive.”
In June, Cracker Barrel posted an unusual earnings report for a restaurant: It’s taking a $5 million hit from tariffs because of its retail shops, which largely has products imported from overseas. Restaurant revenue and same-store sales both slightly grew, mirroring other increases casual dining chains are experiencing.
