Postoperative Pressure Injury in Patients Undergoing Prone Spinal Surgery

Patients undergoing surgery under general anesthesia are susceptible to pressure-induced soft tissue damage because there is no change in posture over an extended period of time. In particular, when the patient is in a prone position, unlike the supine position, the bony protruding portion of the front side must support the weight, which is more vulnerable to pressure injury. Previous studies have shown that the incidence of pressure injury during surgery varied from 5% to 66% and was more likely to occur in patients with long operating times, prone position, obesity, and poor skin condition. These pressure injuries increase postoperative complications, length of stay, and medical costs. Therefore, the investigators analyze the incidence of pressure injury in prone position and re-examine the risk factors of pressure injury.
