Summary

Warming blankets used during prolonged surgeries are a significant risk factor for developing pressure ulcers. Avoiding their routine use may reduce the incidence of these hospital-acquired conditions.

Area of Science:

  • Surgical Patient Care
  • Wound Prevention
  • Medical Device Risk Assessment

Background:

  • Prolonged operative procedures pose a risk for pressure ulcer development.
  • Identifying specific intraoperative risk factors is crucial for prevention strategies.

Purpose of the Study:

  • To identify risk factors associated with pressure ulcer development in patients undergoing lengthy surgeries.
  • To investigate the role of intraoperative interventions in pressure ulcer formation.

Main Methods:

  • A descriptive study involving 33 patients undergoing operations exceeding 10 hours.
  • Utilized the Braden Scale, visual skin inspection, and demographic data collection.
  • Statistical analyses included chi-squared tests and Student's t-tests to compare patient groups.

Main Results:

  • 45% of patients developed stage I or II pressure ulcers within 48 hours post-surgery.
  • A significant association was found between the use of warming blankets and pressure ulcer development (chi 2 = 4.3, p < 0.05).
  • 75% of patients who developed pressure ulcers had been placed on a warming blanket.

Conclusions:

  • Routine intraoperative use of warming blankets should be reconsidered for patients undergoing prolonged surgery.
  • Further research is needed to confirm if eliminating warming blankets reduces pressure ulcer incidence.
  • This finding highlights a modifiable risk factor in surgical patient care.
