Caring for Skin and Healing Wounds

Simon Carver

Alright, folks, welcome back to “Got to be a Nurse, Baby!” Simon Carver here, and as always, I’m joined by my good mate across the pond—Lachlan Reed. Today, we’ve got a topic that, trust me, literally touches every patient: skin integrity and wound care. You ready, Lach?

Lachlan Reed

You bet, Simon! G’day everyone. Mate, skin really is the unsung hero, isn’t it? The old epidermis, dermis, and the delimiter between them—the dermal-epidermal junction—all working round the clock, doing way more than just holding our guts in.

Simon Carver

Exactly. If you picture your skin, that top layer’s the epidermis—thin but mighty. Then you’ve got the dermis underneath, loaded with collagen, giving strength. Right in the middle is the dermal-epidermal junction, kind of like velcro pads keeping both layers together. Mess with that setup, and, uh, you’re in for trouble. Which brings us to pressure injuries. You might know ‘em as bedsores or decubitus ulcers, but honestly, those technical names don’t quite hit home for patients or their families.

Lachlan Reed

Yeah, and why do we worry about ‘em so much, besides the fact they're gnarly? Well, let’s break down what puts folks at risk: impaired mobility—say, someone after hip surgery, can’t roll over well. Or impaired sensory perception—if you can’t feel your heels getting squashed, you won’t shift your weight. Toss in things like reduced consciousness, friction, shear, and moisture, and your risk skyrockets. Shout out to sweaty backs and damp bed sheets—absolute recipe for disaster, mate.

Simon Carver

Don’t forget about the staging, Lach. Pressure injuries run the gamut—stage one is just reddened skin, doesn’t blanch, but the skin’s intact. Stage two means partial thickness—think of a shallow open blister. Stage three, now you’re looking at full-thickness skin loss—sometimes tunneling or undermining starts showing up. Stage four? That’s the deep end—full-thickness skin and tissue loss. And sometimes, it’s just…impossible to stage, especially if it’s covered in slough or eschar, or if it’s a deep tissue injury and just looks like a bruised plum.

Lachlan Reed

Got a quick story here, Simon. Was looking after a bloke—we’ll call him Joe—who had what looked like a nasty pressure sore on his sacrum. Thing is, after the team sorted out moisture and friction—change of sheets, good incontinence care, barrier films—that wound turned right around much quicker than I expected. It’s the small things, sometimes, that make the big difference, eh?

Simon Carver

Yep, that’s teamwork in action, mate. I’ve seen heels saved just by rolling up a spare towel and sticking it under the ankles. And this is all stuff you pick up, sometimes after you’ve already seen one problem go too far. Good news is—we can prevent most of these if we know what to look for.

Simon Carver

So, let’s get into the next piece—the actual healing, which is never as smooth as the textbooks want you to believe. There’s healing by primary intention, like after a surgical incision—you staple it, glue it, close the edges, and let the body work its magic. Then there’s secondary intention, where edges can’t just be pulled together—think about those same nasty pressure injuries. More time, more scar tissue, higher risk for infection.

Lachlan Reed

And then you’ve got tertiary intention—also called delayed primary closure. Did this once on a abscess—had to leave it open to start, bit of wound packing, then came back to close it once the gunk was gone. If you think of wound depth: partial-thickness wounds are just superficial, but full-thickness goes all the way down—sometimes even to muscle or bone. It’s proper gnarly, especially on a diabetic foot! Honestly, some wounds heal better on their own—if you give them a fighting chance with good nutrition and perfusion.

Simon Carver

Right, and it’s not just about the wound itself. There are a million factors that can help or completely derail healing. Nutrition is huge—I’m talking protein, vitamins, all that good stuff. Poor perfusion means not enough oxygen gets to the wound, so, slow healing. Infection can turn even a minor wound into a marathon. Age? Not to be rude, but skin just doesn’t bounce back the same way when you’re eighty as it does when you’re twenty-eight.

Lachlan Reed

Don’t remind me, mate. And sometimes you get nasty surprises—dehiscence, when the wound pops open, or the real horror show: evisceration, when contents come out. Nearly missed a wound infection once myself. Leg wound just wasn’t granulating—bit more red, there was heat around it, WBC counts climbing. Lucky, the team caught it before it went septic. Always trust your instincts, and get fresh eyes on a tricky wound if something feels off.

Simon Carver

Acute wounds, like surgical ones, follow a pretty predictable timeline—hemostasis, inflammation, proliferation, maturation. Chronic wounds, though? Different beast. They sort of get stuck in those early stages, don’t they, Lach? That’s where tools like the Braden Scale become lifesavers—we’re not just fixing what's in front of us, we’re figuring out why it isn’t fixing itself. Clinical judgment is king here; it’s not one-size-fits-all.

Lachlan Reed

Absolutely. You learn pretty quick that assessing a wound is about the whole patient, not just the hole in the patient. Take a moment to eyeball their nutrition, mobility, circulation—and tweak your care plan for exactly what’s going on in front of you. Makes all the difference.

Simon Carver

Let’s walk through putting this all into action. When you assess a wound, it’s more than just a cursory glance. You need to know the wound type—abrasion, laceration, puncture? Pressure injury? Check the base—are you dealing with granulation tissue, slough, eschar, exudate? Track the size, color, location. Drainage? Is it scant or copious? And, crucial—look at the big picture, not just the wound. Labs can tell you heaps: low hemoglobin means less oxygen for healing, elevated WBC points to infection, low albumin means there’s not enough protein building-blocks, and so on.

Lachlan Reed

Spot on, mate. You can’t wing this stuff. Evidence-based nursing interventions start with good risk assessment—like using the Braden Scale to ID risk for pressure injuries. Repositioning patients, picking the right dressings—whether that’s hydrocolloids or alginates—plus advanced options like debridement or irrigation for wounds that need it. Don’t forget support surfaces, either. A cheap egg crate pad can sometimes make the difference between a stage one pressure injury and a full-blown disaster.

Simon Carver

Absolutely, and let’s actually flesh that out with a quick case, since teamwork’s been a theme for us lately. Say we’ve got a patient, Mrs. D, who’s immobile after a stroke. Braden score’s low, albumin’s borderline, and you spot a red, non-blanchable area on her heel at the start of your shift. What’s your move, Lach?

Lachlan Reed

First up, I’m using clinical judgment—she’s at risk, so I’d get her off that heel straight away, maybe use a pillow. Then check for any moisture—decent barrier cream goes a long way, mate. Make a plan for regular repositioning, monitor the wound, grab baseline labs if they’re not done, and loop in dietary. Communication’s key—let the team know what you’ve seen, so it doesn’t get missed at handover. Keep reevaluating—sometimes, even the best plans need tweaking after a day or two.

Simon Carver

Exactly. Maybe if her wound progresses, we consider a hydrocolloid dressing, keep an eye out for drainage changes, involve wound care if needed. All about adapting. And, if your interventions work—celebrate it! If not, keep collaborating and trying new approaches. Ongoing evaluation, that’s the name of the game.

Lachlan Reed

Alright, I think that’s a wrap for today—hopefully this helped take the mystery out of wound care, even just a little. We’re all learning as we go! Simon, mate, as always—great teaming up. Can’t wait for what’s next.

Simon Carver

Yeah, cheers, Lach. And thanks to everyone for listening in, whether you’re cramming for an exam or tuning in from a night shift. Remember—every wound, every patient, every shift—it’s teamwork that makes a difference. Catch you next episode. Take care, everyone!
