Comparaison of Two Prone Position Techniques on Occurence of Pressure Sores in ICU

"Patients will be positioned with the head rotated. This rotation is followed by shoulder elevation/abduction, then 90° elbow flexion for the arm opposite to the head rotation. The hand is placed flat on the bed.~A 60° to 90° flexion is performed on the hip homolateral to head rotation, combined with knee flexion.~The position is changed to the mirror position every 4 hours."

"The head will be positioned either straight or rotated to one side, depending on ICU habits. The arms are positioned symmetrically along the body, palms up. The lower limbs are positioned symmetrically and parallel, knees extended or slightly flexed if a cushion is used on the front of the feet.~Head rotation, if applicable, is performed every 4 hours."
