Where Should You Tie a Restraint on a Bed? A Guide to Safe Practice

4 min read

According to numerous nursing standards, improper restraint application can lead to serious injury or death, a critical reminder for anyone asking where should you tie a restraint on a bed. This authoritative guide explains the correct and safe procedure for securing restraints, ensuring patient dignity and safety above all.

Quick Summary

For patient safety, physical restraints should always be secured to the immovable part of the bed frame, never to the side rails or any other moving component. You must also use a quick-release knot.

Key Points

  • Secure to the Immovable Frame: Always tie restraints to the stationary, non-movable part of the bed frame, never to the adjustable side rails or head/foot sections.

  • Use a Quick-Release Knot: For emergency situations, a quick-release knot (like a slipknot) is mandatory for fast removal.

  • Leave Space for Circulation: Ensure you can fit two fingers between the restraint and the patient's skin to prevent constriction and injury.

  • Emphasize Continuous Monitoring: Regular checks of skin integrity, circulation, and patient comfort are critical after a restraint is applied.

  • Explore All Alternatives First: Restraints are a last resort. Implement and document less restrictive measures, such as alarms or environmental changes, before resorting to physical restraints.

  • Ensure Bed Safety: The bed should be in the lowest position with the wheels locked, and the call light must be within the patient's easy reach.

Understanding the 'Why' Behind Proper Restraint Placement

When a healthcare provider determines that a restraint is medically necessary, the correct procedure is paramount. The location where a restraint is tied directly impacts patient safety. Tying a restraint to a movable part of the bed, such as a side rail, is extremely dangerous. If the head or foot of the bed is adjusted, the restraint's tension will change, potentially becoming too tight and restricting circulation, or too loose, allowing the patient to become entangled. Therefore, the absolute rule is to attach restraints only to the immovable portion of the bed frame.

The Critical Difference: Bed Frame vs. Side Rail

Many people mistakenly believe that tying a restraint to the side rail is acceptable. This is a common and potentially fatal error. The table below outlines the critical distinctions between these two methods and why one is strictly forbidden.

Feature Secured to Bed Frame (Safe) Secured to Side Rail (Unsafe)
Effect of Bed Adjustment Tension remains constant and safe, regardless of bed position changes. Tension changes unpredictably, risking strangulation or nerve damage.
Patient Entrapment Risk Minimized. Patient is secured safely to a stable part of the bed. High. Patient could get tangled as bed moves, increasing fall or injury risk.
Application for Mobility Correct application accounts for the patient's needed range of motion. Can severely restrict necessary movement, leading to pressure injuries.
Quick Release Access Knot is easily accessible for a caregiver to release in an emergency. Caregivers may struggle to access the knot if the bed position changes unexpectedly.

Step-by-Step Guide to Applying Restraints Correctly

  1. Assess the Need: Before applying a restraint, all less-restrictive alternatives must be attempted and documented. The use of restraints is a last resort and must have a specific medical order.
  2. Inspect the Area: Check the patient's skin and limbs where the restraint will be placed for any cuts, swelling, or signs of poor circulation. Pad any bony prominences to prevent skin breakdown.
  3. Choose the Right Equipment: Use the correct size and type of restraint as per facility policy. Never use improvised restraints like ropes, blankets, or tape.
  4. Position the Patient: Ensure the patient is in proper body alignment and comfortable before application. This prevents strain and discomfort.
  5. Apply the Restraint: Wrap the restraint around the correct body part (e.g., wrist or ankle), ensuring you can fit at least two fingers between the restraint and the patient's skin. This prevents it from being too tight.
  6. Secure to the Bed Frame: Pass the strap through the appropriate loop on the restraint and then secure it to the immovable part of the bed frame. Ensure it is attached to a part that does not move when the head or foot of the bed is raised.
  7. Tie a Quick-Release Knot: This is non-negotiable. A quick-release knot, like a slipknot, must be used. This allows for immediate removal in an emergency, such as a fire or sudden medical event. Never use a square knot or any other knot that requires manipulation to undo.
  8. Lock the Bed and Ensure Safety: After securing the restraint, lock the bed's wheels and place it in the lowest possible position. Ensure the call light is within the patient's reach.

The Role of Constant Monitoring and Alternatives

Applying a restraint is not a 'set it and forget it' action. Constant, regular monitoring is a cornerstone of safe practice. Staff must check the patient frequently, assessing for proper placement, skin integrity, circulation (temperature, color, and sensation), and the patient's overall comfort. The restraints should be removed periodically to allow for range-of-motion exercises, toileting, and repositioning to prevent complications like pressure ulcers.

Modern senior care increasingly focuses on restraint alternatives. These methods prioritize patient comfort and dignity while maintaining safety. Examples include bed or chair alarms, visual and auditory cues, regular rounding, and environmental modifications like low beds or specialized cushions. An effective approach uses restraints only as a temporary measure while simultaneously investigating and implementing safer, long-term alternatives. For more information on alternatives, refer to the American Nurses Association's guidelines on restraint reduction.

Conclusion: Prioritizing Patient Well-being

Knowing where should you tie a restraint on a bed is a fundamental part of patient safety. By understanding the critical distinction between the bed frame and side rails, using a proper quick-release knot, and maintaining a rigorous schedule of monitoring, caregivers can minimize the significant risks associated with restraints. This technical knowledge, combined with an ethical commitment to exploring and implementing alternatives, ensures that patient dignity and safety are always the highest priority in a care setting.

Frequently Asked Questions

Tying a restraint to a side rail is extremely dangerous because the rail moves when the bed is adjusted. This can cause the restraint to tighten, leading to restricted circulation, strangulation, or nerve damage, or loosen, causing the patient to become entangled.

You must use a quick-release knot, such as a slipknot. This type of knot can be undone quickly with a single pull in the event of an emergency, allowing for rapid patient release.

A standard safety check is the two-finger test. You should be able to easily fit two fingers between the restraint and the patient's skin. If you cannot, the restraint is too tight and should be adjusted immediately.

Alternatives include using bed or chair alarms, ensuring a comfortable environment, addressing underlying pain or agitation, providing frequent attention, and engaging the patient in appropriate activities. Restraints are a last resort after these options have failed.

Facilities have specific policies, but constant and regular monitoring is required. This involves frequent checks of the patient's circulation, skin integrity, and overall well-being. Restraints should also be removed periodically for repositioning and range-of-motion exercises.

Yes, if all four side rails are raised, they are generally considered a restraint because they prevent the patient from voluntarily getting out of bed. Full side rails should only be used when medically necessary and based on a comprehensive assessment.

No, absolutely not. It is unethical and illegal to use a restraint for staff convenience, punishment, or as a substitute for adequate staffing. Restraints are a last resort for medical or safety purposes only.
