Night Pain That Changes the Compression Plan
Mrs. K is 74, BMI 34, with a 12-week history of a 4 × 3 cm ulcer at the right medial gaiter. The wound bed is about 70% slough with heavy serous drainage; the periwound skin is macerated, with hemosiderin staining and 3+ pitting edema to the knee. She has a history of DVT in that leg and hypertension, and takes furosemide. The hospital's standing order set says: "apply 40 mmHg multilayer compression." Her ABPI today is 0.72. She tells you she wakes at 2 a.m. with burning across the forefoot that eases when she sits up and lets the leg hang down. She asks whether the bandages will finally get the swelling down.
1. The standing order says 40 mmHg. Do you apply it? Walk through the decision.

No. I would hold the order and escalate the same day. Two findings conflict with it:
- The ABPI of 0.72 falls below the usual threshold for full 40 mmHg multilayer compression (generally an ABPI of at least 0.8; 0.6–0.8 is reserved for modified, closely supervised compression).
- More important, she describes nocturnal burning relieved by dependency, which is ischemic rest pain. Compression in the presence of rest pain can precipitate skin necrosis and, at worst, amputation.
When a number and a clinical sign disagree, the sign wins. ABPI also overstates perfusion in obesity, renal disease, and diabetes because of vessel calcification, so 0.72 may be optimistic rather than accurate.
The safe sequence: withhold compression, document the reason and the exact words she used about night pain, notify the ordering provider by name and time, and refer for vascular assessment (duplex, toe pressures) before any compression is considered. If perfusion proves adequate, graduated reduced compression under supervision with reassessment at 24–48 hours.
Leaving the bandage off without a note and a call is not caution - it is an omission the next clinician will undo blindly.
2. Meanwhile the wound is 70% slough with heavy drainage and the periwound is macerated. What do you put on it, and what do you avoid?

Priorities in order: protect ischemic tissue, control exudate, protect skin, add no trauma.
Choose: a superabsorbent or hydrofiber primary dressing with a non-adherent contact layer, held by a soft secondary dressing that does not constrict. Apply a barrier film to the macerated periwound before anything else.
Avoid:
- Aggressive sharp debridement of slough while perfusion is unproven - in arterial disease this converts slough into a painful, non-healing wound.
- A cohesive or tubular bandage used "just to hold the dressing on." That is compression by another name and it will not be documented as such.
- Routine topical antibiotics or silver absent signs of critical colonization; antimicrobials are not a substitute for perfusion.
- Prolonged leg elevation above heart level - it improves the edema and worsens the ischemia.
I would tell her and the team to expect the ulcer to look worse, not better, until perfusion is addressed, so that a lack of progress is not misread as a dressing failure.
3. Her edema will not resolve without compression. How do you handle that tension, and what exactly do you hand off?
Read the worked answer
Name the tension rather than resolving it with a compromise that satisfies nobody: edema drives the ulcer, compression treats the edema, but compression is unsafe when inflow is inadequate. The resolution is sequence, not a middle dose chosen arbitrarily.
- Vascular evaluation first (duplex, toe pressure). If she is a candidate, revascularization precedes compression.
- Once perfusion is confirmed (toe pressure generally above 30–40 mmHg and no rest pain), start modified, supervised compression with a short-stretch system, applied by someone who will inspect the foot within 24–48 hours.
- Non-compressive adjuncts in the interim: elevation to heart level only, ankle pumps if mobility allows, and a fluid and salt conversation with the prescriber.
- A written reassessment date, not "follow up as needed."
If compression never becomes safe, the plan legitimately shifts to stabilization and palliation - and she and her family should hear that from a clinician rather than infer it from silence.
Handoff: the note, the named provider notified, the vascular referral, the dressing plan, and the instruction that compression requires a documented perfusion assessment before it is applied.
