Repositioning Paralyzed Patients: Evidence-Based Turning Schedules and Prone Positioning Indications

Safe Repositioning for Immobility: Preventing Complications

Contrary to the myth that paralyzed patients should not be turned, regular repositioning is essential to prevent pressure injuries, atelectasis, contractures, and thromboembolism. The standard is every 2 hours (or per individualized plan), alternating between supine, left lateral, right lateral, and 30° lateral positions.

Prone Positioning: Specific Indications, Not Routine

Turning fully prone (face down) is not routine for all paralyzed patients. It is a targeted intervention for:

• Severe ARDS: Improves V/Q matching, dorsal lung recruitment (PROSEVA trial protocol: 16+ hrs/day).
• Posterior surgery/wounds: Offloads sacrum/ischial tuberosities.
• Specific neurological conditions: E.g., prone ventilation in high cervical SCI with respiratory failure.

Risks of Improper Prone Positioning

• Facial/ocular pressure injuries (corneal abrasion, blindness).
• Airway compromise, endotracheal tube displacement.
• Hemodynamic instability.
• Brachial plexus stretch injury.
• Increased ICP in traumatic brain injury (controversial).

Key Principles

• Use pressure-redistribution surfaces (foam, air, gel overlays).
• Offload bony prominences with pillows/foam wedges (30° lateral tilt preferred over 90°).
• Document position, time, skin assessment, and tolerance.
• Multidisciplinary protocol for prone ventilation (requires trained team, checklist).

Repositioning is a cornerstone of nursing care for paralysis—individualized, documented, and proactive.
