Quantifying and Visualizing the Pressure: Pressure Injury Prevention in the Operating Room
Summary: March 2026 article explores pressure injury prevention in the operating room using pressure mapping technology to quantify and visualize interface pressures between patient skin and OR surfaces (mattresses, tables, positioning devices). High pressures (>32 mmHg prolonged) during surgery contribute to intraoperative pressure injuries (prevalence 8.5–34.5%). Study/methods: Real-time mapping identifies hotspots (sacrum, heels, occiput), correlates with duration/positioning. Interventions: Pressure-redistributing overlays, gel pads, heel protectors, frequent micro-adjustments. Outcomes: Reduced peak pressures, better distribution, lower injury risk. Emphasizes multidisciplinary protocols (anesthesia, nursing, surgeons), documentation, and education. Ties to NPIAP guidelines; calls for routine mapping in high-risk cases (long procedures, immobility). Supports proactive, tech-enabled prevention in surgical/chronic care settings.
Key Highlights:
- Tech: Pressure mapping quantifies hotspots in real time.
- Risks: Prolonged high pressures during anesthesia/immobility.
- Solutions: Offloading aids, positioning changes, protocols.
- Relevance: Prevents iatrogenic pressure injuries in vulnerable patients.
