Curvilinear Positioning and Micromovement Reduce Surgical Pressure Injuries
Comparing the effects of curvilinear position and micromovement on prevention of intraoperative acquired pressure injuries among patients undergoing surgery in the supine position: A randomized controlled trial.
Injury . 2025 Jun;56(6):112327.One hundred and twenty patients undergoing open general surgery in the supine position were randomized to curvilinear positioning (n=40), micromovement (n=40), or standard supine care (n=40). The primary outcome was Intraoperative acquired pressure injury (IAPI) incidence; secondary outcomes included IAPI stage and location. Outcomes were assessed immediately post-op and on postoperative day 1. Overall, the results showed significantly fewer IAPIs with micromovement or curvilinear positioning versus control, with most injuries at the sacrum; stage and location distributions did not differ between groups. These findings suggest that simple table-based positioning strategies can lower IAPI risk during prolonged supine surgeries.
