Intraoperative pressure sore prevention: an analysis of bedding materials
1Thomas Jefferson University Hospital, Philadelphia, PA 19107.
This study looked at how different operating room table surfaces affect pressure sore development during surgery. Researchers followed 505 patients and found that overlays provided better protection than standard foam or gel surfaces. Patients with longer surgeries, those over 40, and those with vascular disease were more likely to develop skin changes. The study suggests that using overlays could help prevent pressure sores in high-risk patients. The findings highlight the importance of considering both patient factors and material choices in surgical settings.
Area of Science:
- Surgical outcomes research in orthopedic and general surgery
- Wound prevention in clinical nursing
- Medical device evaluation in perioperative care
Background:
Pressure injuries remain a significant concern during surgical procedures. Prior research has shown that prolonged surgical duration increases risk. It was already known that patient age and comorbidities influence vulnerability. No prior work had resolved how OR table materials interact with these risk factors. This gap motivated examining the interplay between bedding materials and patient outcomes. That uncertainty drove a focus on how different surfaces affect skin integrity. No prior work had resolved whether overlays offer better protection than standard foam. This study aimed to clarify these relationships.
Purpose Of The Study:
This study aimed to evaluate how OR table surfaces influence pressure sore development. The specific problem addressed was identifying which materials best prevent skin changes. The motivation stemmed from rising surgical durations and aging patient populations. The goal was to determine if overlays outperform standard foam or gel surfaces. Researchers sought to quantify the effectiveness of different bedding types. They also aimed to identify patient risk factors beyond surgical duration. No prior work had resolved how overlays compare to standard foam in real-world settings. This study sought to fill that gap.
Main Methods:
The study involved 505 patients undergoing surgical procedures. Preoperative assessments used the Hemphill scale for pressure sore risk. Postoperative skin evaluations were conducted to detect changes. Data collection included surgical duration, patient age, and comorbidities. Researchers compared outcomes across three bedding types: standard foam, gel, and overlay. Statistical analysis identified correlations between materials and skin integrity. Variables like vascular disease and Hemphill scores were factored into models. The study design allowed for tracking how surface choices impact outcomes.
Main Results:
Patients with surgery longer than 2.5 hours had higher skin change rates. Those aged 40+ or with vascular disease were more vulnerable. A preoperative Hemphill score of 4+ predicted increased risk. The overlay surface showed better protection than standard foam or gel. Standard mattress-only setups had the highest incidence of skin changes. No significant difference was found between gel and standard foam. The most effective material was the overlay in preventing pressure sores. These findings suggest overlays may reduce risk in high-risk patients.
Conclusions:
The authors propose that overlays offer better protection than standard foam or gel surfaces. They suggest that surgical duration exceeding 2.5 hours increases risk. Age and vascular disease are linked to pressure sore development. A Hemphill score of 4+ indicates higher vulnerability. The study implies that material choice matters in preventing skin changes. These findings suggest that overlays may be preferable in high-risk scenarios. No prior work had resolved how overlays compare to standard foam in real-world settings. The authors propose that patient and procedural factors must be considered together.
