How can positioning during surgery prevent nerve injury and pressure ulcers?

• A. Regular repositioning every 30 minutes.
• B. Adequate padding, proper alignment, avoiding prolonged pressure on bony prominences, and regular reassessment during long cases.
• C. Positioning does not affect nerve injury risk.
• D. Only use padding for pediatric patients.

Answer: (B)

Positioning during surgery aims to prevent nerve injuries and pressure ulcers by reducing nerve traction and compression and by avoiding sustained pressure on vulnerable tissues when the patient cannot feel discomfort under anesthesia. The best approach brings together padding to cushion bony prominences, careful alignment to keep joints in a neutral, non-stressful position, avoidance of prolonged pressure on high-risk areas (such as pressure points over bony prominences), and regular reassessment during long cases to detect shifting pressure points or new risks and adjust immediately. This combination directly addresses both nerve injury from compression or stretch and tissue damage from prolonged pressure. Regular repositioning alone helps but isn’t enough without padding, proper alignment, and ongoing checks, and padding benefits patients of all ages, not just pediatric patients.
