Principles and Techniques of Bandaging

TL;DR: Quick Guide to Bandaging Principles

Bandaging is the application of specific bandages and binders for wound protection, support, compression, and immobilization. Key principles include proper fixation, padding bony areas, using absorbent materials, and rigorous circulation checks. Different types of bandages (gauze, elastic, tubular, triangular) and turns (circular, spiral, figure-eight, recurrent) are used for various body parts and purposes. Always ensure patient comfort, use the correct bandage width, and follow a systematic wrapping procedure, moving from narrower to wider areas, with regular checks for impaired circulation.

Principles and Techniques of Bandaging for Students

Welcome to your essential guide on the principles and techniques of bandaging! Understanding how to properly apply bandages is a fundamental skill in healthcare, crucial for protecting wounds, providing support, and ensuring patient comfort and safety. This article breaks down everything from the basic definitions to advanced wrapping techniques, specifically tailored for students.

What is Bandaging? Understanding the Basics

Bandaging (also known as Desmurgy) involves applying specific bandages and binders to different parts of a patient's body. Bandages are typically strips of gauze or other materials designed to cover or bind body parts and hold dressings in place. Many are rolled for easy application and can be clean or sterile.

Binders, also known as compression belts, are specialized bandages made for specific body areas like the abdomen, arm, chest, breast, or perineum.

Purpose of Bandages: Why Do We Apply Them?

Bandages and binders offer numerous therapeutic benefits and serving vital purposes in patient care. These include:

• Protection of the wound
• Holding dressings securely in place
• Providing compression to reduce swelling
• Offering support to injured areas
• Immobilization of a limb or joint
• Redressing existing wounds
• Providing traction when needed

Core Principles of Roller Bandage Application

Applying a roller bandage correctly requires adherence to several key principles to ensure effectiveness and prevent further injury:

• Fixing the Bandage: Secure the end using a plaster tape, by tying the bandage, or with metal clips. This prevents the bandage from unraveling.
• Skin Protection: Always use absorbent materials like cotton wadding or gauze between touching skin surfaces. This helps absorb moisture, significantly reducing skin irritation and injury.
• Padding Bony Prominences: Pad any bony prominences over which bandages are placed. This helps to distribute pressure equally and prevents pressure sores or discomfort.

Ensuring Patient Safety: Circulation and Nerve Function Checks

Crucial to any bandaging procedure is monitoring the patient for signs of impaired circulation or nerve function. This ensures the bandage isn't applied too tightly. Regularly assess the following:

• Skin color: Look for changes like bluish discoloration.
• Skin temperature: Feel for coldness in the bandaged area.
• Sensation: Check for numbness or tingling in fingers or toes.
• Swelling: Observe for any new or increased swelling.
• Pain: Ask the patient about any new or worsening pain.
• Pulse: Check the pulse distal to the bandage, if applicable.

Specifically, look for bluish coloring of the skin and nailbeds, coldness, numbness, swelling, and tingling pain. Check the bandage and binders at regular intervals, noting circulation and proper body alignment.

Types of Bandages: A Comprehensive Overview

There's a wide variety of bandages, each suited for different applications and parts of the body.

Roller Bandage Varieties

• Gauze bandage
• Elastic (compression) bandage
• Padding bandage
• Tubular bandage

Other Specialized Bandages

• Fixing bandages: These include Zinc paste, Starch, and Gypsona plaster bandages, used for rigid support.
• Tubular elastic net (mesh) bandages: Such as Pruban, these hold dressings in place easily.
• Tailed bandages: Bandages with multiple tails for specific applications.
• Dressings (Compressions): Materials directly applied to wounds.
• Tapes (plasters): Adhesive strips for securing dressings or light support.
• Sprays: Adhesive or protective sprays.
• Splints: Devices like plaster, vacuum, or pneumatic splints for immobilization.
• Elasticized (compression) stockings: Used for circulatory support, often on legs.
• Triangular bandage: Highly versatile, used as slings, covers, or for securing splints.
• Cravat Bandage: A folded triangular bandage used for various bindings.

Basic Turns for Roller Bandages: Mastering Application Techniques

Different body parts and injury types require specific bandage turns for optimal effectiveness and comfort. Understanding these basic bandage turns is key to proper application.

Circular Turns for Anchoring and Termination

• Circular turns are fundamental, primarily used to anchor a bandage at the beginning and to terminate it at the end of the wrap. They create a secure base and finish.

Spiral Turns for Uniform Body Parts

• Spiral turns are ideal for bandaging body parts that have a relatively uniform circumference, such as the upper arm or upper leg. These can be applied as:
• Slow spiral turns
• Rapid spiral turns

Spica Turns for Cylindrical Areas

• Spica turns are specifically designed for bandaging cylindrical body parts or joints, allowing for secure coverage around contours.

Figure-Eight Turns for Joint Mobility

• Figure-eight turns are excellent for bandaging joints like the elbow, knee, or ankle. They are preferred because they permit some movement after application. These include:
• Divergent turns
• Convergent turns

Recurrent Turns for Distal Parts

• Recurrent turns are used to cover the distal parts of the body. This technique is applied over the end of fingers, the skull, or the stump of an amputation.

Step-by-Step Procedure for Roller Bandage Application

Following a systematic procedure ensures the bandage is applied correctly and safely:

1. Hand Hygiene: Begin by washing hands and using an alcohol hand rub to maintain sterility.
2. Patient Information: Inform the patient about the procedure. Explain the importance of reporting any numbness, tingling, skin discoloration, pain in the bandaged area, or any drainage/bleeding that soaks through.
3. Positioning: Place the patient in a comfortable position, either sitting or lying down.
4. Maintain Contact: Stand in front of the patient and maintain contact during the application.
5. Limb Positioning: Carefully put the treated body part into a comfortable and stable position.
6. Bandage Width Selection: Use the appropriate width of bandage for the specific body part:

• 2.5 cm bandage for fingers
• 5 cm for an arm
• 7.5 cm or 10 cm for a leg

7. Wound Dressing: Cover any open wound with a sterile dressing before applying the bandage.
8. Hold Correctly: Hold the roll of bandage correctly, ensuring it unwinds smoothly.
9. Start Bandaging: Begin bandaging at the narrower part of the body and gradually move towards the wider one.
10. Secure Start/End: At the beginning and end of each bandage, secure it with a circular wrap.
11. Overlap: All wraps should be carried out in a specific direction, with each subsequent wrap covering the previous one by approximately two-thirds.
12. Joining Bandages: If a new bandage is needed, place its beginning under the loose end of the previous one, then repeat the wrap to secure it.

By following these principles and techniques of bandaging, you'll be well-equipped to provide effective and safe care.

Frequently Asked Questions about Bandaging (FAQ)

Students often have questions regarding the practical application and safety aspects of bandaging. Here are some common inquiries:

How do you fix a roller bandage securely?

You can fix a roller bandage securely using plaster tape, by tying the end of the bandage, or by using metal clips provided with the bandage. The goal is to prevent it from unraveling and maintain constant pressure.

What are the key checks for impaired circulation after bandaging?

After bandaging, regularly check for bluish skin and nailbeds, coldness, numbness, tingling pain, swelling, and assess the pulse distal to the bandage. These are vital signs indicating the bandage might be too tight.

When should I use spiral turns versus figure-eight turns?

Use spiral turns for body parts with a relatively uniform circumference, like the upper arm or leg. Use figure-eight turns for joints such as the elbow, knee, or ankle, as they allow for some movement while still providing support.

Why is it important to pad bony prominences when bandaging?

Padding bony prominences like elbows or ankles is crucial to help maintain equal pressure across the bandaged area. This prevents excessive pressure on the bone, which can lead to discomfort, pressure sores, and tissue damage.

What is the correct way to start and end a roller bandage?

The correct way to start and end a roller bandage is by using circular turns. Begin with a few circular turns to anchor the bandage securely, and finish with circular turns to terminate the wrap, ensuring it is fixed firmly in place.
