Who This Checklist Is For

If you're a nurse, surgeon, or wound care specialist managing post-operative or chronic wounds in a hospital setting, this is for you. You're already using advanced dressings—maybe Mölnlycke Mepilex for pressure injuries or Melgisorb Plus for exudating wounds. But you're wondering: how do I know if the healing is on track without waiting for a weekly wound photo?

The answer is right there on the patient monitor. I'm talking about the vital signs you're already tracking: heart rate, temperature, respiratory rate. The trick is knowing what to look for when you've got a Mölnlycke dressing in place. This checklist gives you the 5 steps to connect the dots—no guesswork.

Full disclosure: I'm a clinical educator at a Level 1 trauma center. In the last two years, I've trained over 200 nurses on wound assessment protocols. This checklist is based on what I've seen work—and what I've seen get missed.

Step 1: Check the Temperature Trend (Not Just the Number)

You pull up the patient monitor. Temperature: 37.2°C. Looks normal. But here's what I've learned the hard way: the trend matters more than the single reading.

When a patient has a Mölnlycke Melgisorb Plus dressing on a moderately exudating wound, a creeping temperature over 24 hours—say from 36.8°C to 37.4°C—is often the first sign of a localized infection. You won't see it in the wound bed yet because the dressing is doing its job, absorbing exudate and maintaining a moist environment. But the body is already mounting a response.

"In April 2024, I had a patient with a diabetic foot ulcer, covered with Melgisorb Plus. Temperature went from 37.0 to 37.6 over 36 hours. No visible change in the wound. But the trend told us to check deeper. We found a small abscess forming under the wound bed. Caught it early."

What to do: Document temperature at least twice daily. If you see a consistent 0.5°C rise over 24 hours, flag it—even if the wound looks fine.

Step 2: Watch the Heart Rate—It's an Early Warning

Heart rate is the underrated vital sign in wound care. Everyone looks at temperature and WBC count. But a persistently elevated heart rate—especially if the patient is afebrile—can signal systemic inflammation or even early sepsis.

Here's a scenario you've probably seen: patient with a large surgical wound covered by a Mölnlycke Mepilex Border dressing. Heart rate is 95 bpm. Not alarming by itself. But if it was 72 bpm yesterday and now it's 95 bpm with no other change? That's a red flag.

What most clinicians miss: A Holter monitor or continuous telemetry can give you this trend automatically. If you're using a patient monitoring system that tracks HR variability, you can spot autonomic changes hours before a fever develops.

"We had a post-op patient on a Mepilex dressing for a hip replacement wound. HR went from 68 to 92 over 6 hours. No fever, no pain spike. The wound looked clean. But the HR trend pushed us to do an ultrasound. Found a deep hematoma that was starting to get infected. That quick action saved a revision surgery."

What to do: Set a baseline HR at dressing change. If HR increases by more than 15 bpm sustained over 4 hours, escalate review—even if the wound looks unremarkable.

Step 3: Interpret the Respiratory Rate—Harder to Fake

Respiratory rate is the vital sign most often ignored. It's also the one least influenced by patient anxiety or movement. For wound care, a rising respiratory rate can mean two things:

• Pain: The patient is breathing shallowly and faster because moving hurts. This is especially common with large abdominal wounds, even with an atraumatic dressing like Safetac® technology.
• Systemic infection: Tachypnea is an early compensatory mechanism for metabolic acidosis, which can accompany wound infection or sepsis.

I've seen nurses document RR as 'normal' because the patient looks comfortable. But if you actually count—a sustained rate above 22 breaths/min when the patient is at rest, with no COPD or asthma history—that's a flag.

Put another way: The patient is telling you something, even if they're not saying a word. A rising RR with a stable SpO2 is suspicious for pain or early systemic response.

What to do: Count respiratory rate at least once per shift, manually, for 30 seconds. Document it alongside the wound assessment. A rate consistently above 22 should trigger a wound evaluation.

Step 4: Correlate Pain Scores with Dressing Changes

This is the step most people get wrong because they treat pain as a separate issue. But pain is a vital sign, and for wound care, pain trends related to dressing changes are gold.

If you're using Mölnlycke Mepilex or Melgisorb Plus, you're already benefiting from Safetac® silicone adhesive technology, which minimizes trauma on removal. That means any new or increasing pain during dressing change is clinically significant—it's not just from the adhesive.

I always tell my team: 'If the pain score goes up by 2 or more points during the scheduled dressing change, and the wound looks the same, don't assume it's normal. Check for tunneling, undermining, or early infection.'

"Saved a patient from a nasty complication back in Q1 2024. She had a chronic leg ulcer with Melgisorb Plus. Pain at dressing change went from 3/10 to 6/10 over 3 days. Wound looked fine, but we did a probe and found a sinus tract forming. Changed the treatment plan immediately."

What to do: Document pain immediately before, during, and after dressing change. A consistent increase of 2+ points on the pain scale over 2 consecutive changes = investigate.

Step 5: Use the Monitoring System Data, Not Just the Numbers

Most hospitals have patient monitoring systems or even Holter monitors for cardiac patients. But the data from these systems is rarely applied to wound assessment.

Here's what I mean: If a patient on a wound care protocol is also being monitored for cardiac rhythm, you can use that data to spot autonomic changes. A sudden increase in heart rate variability (HRV) can indicate parasympathetic withdrawal—an early stress response that often precedes clinical signs of infection by 12 to 24 hours.

How to actually read it:

• Look for trends in mean HR over 6-hour windows.
• Check if there's a new onset of tachycardia (HR >100) that wasn't there before.
• If the patient has a Holter monitor, review the HR variability report. A drop in HRV of more than 20% from baseline is suspicious.

"In 2023, we had a surgical patient on telemetry. The monitoring system flagged a persistent HR increase from 78 to 102 over 8 hours. No fever, no pain. We examined the wound—covered with Mepilex—and found early cellulitis spreading around the edges. The dressing was intact, but the infection was already moving."

What to do: Configure your patient monitoring system to alert on HR trends, not just absolute thresholds. A sustained increase of 15 bpm over 4 hours should trigger a wound check.

What Most Clinicians Get Wrong

Mistake #1: Treating vital signs as independent data points. They're not. A single elevated temperature means little. A combination of rising HR and RR over 12 hours means a lot, especially if the wound is covered with an advanced dressing that hides early changes.

Mistake #2: Relying only on what you can see. Mölnlycke dressings are designed to maintain a moist healing environment—which is great for healing, but it means you can't always see the early signs of infection. The vital signs are often ahead of the visual change.

Mistake #3: Not documenting the baseline. You can't spot a trend if you don't have a starting point. At the first dressing application, document HR, RR, temperature, and pain score. That's your reference.

A Quick Note on the Tools

If you're using a patient monitoring system that integrates with your EMR, you can set automated alerts for HR and RR trends. Most systems have this capability, but it's rarely configured for wound care. Talk to your biomedical team. It takes 15 minutes to set up and can save your patient a week of antibiotics.

For Holter monitors, the HRV data is usually available in the software. Ask your cardiology team to flag any significant drop in HRV for your wound care patients. Again, it's data you're already collecting but not using.
