PARAFFIN

WAX


2/28

INTRODUCTION Therapeutic wax bath is one of the

forms of heating conduction by wax.

Wax baths are available in manyvariations of size and shape.

The melted wax need to be maintained

at a temperature of 40- 44degree . So thermostatic control is essential.


3/28

ApparatusWax bath tank. Stainless steel.

Height adjustable. Thermostat control.

Temperature :- 40-44 degrees. Liquid paraffin (natural oil) + wax.

Ratio is 6:1 or 7:1.


4/28

Mode of Action Water at 45 temp is uncomfortable and can cause

damage.

Specific heat of water :- 4.2 kj/kg/degree c.

Specific heat of wax :-2.7 kj/kg/degree c. Therefore , the energy released by wax is 1 degree

c cooler than that of water.

The wax transmits its latent heat to tissues bygiving up its energy as it solidifies.

TECHNIQUESOF

APPLICATION:- Dip and wrap method

Dip and re-immersion method Painting or brushing method

Bandaging and toweling method

Direct pouring method or bath method


6/28

Dip and Wrap

Method. Extremity is dipped for few minutes and

taken out. Repeated 7-12 times.

Wrap with a insulator sheet of plastic.

Site fingers, wrist, toes, ankle.


7/28

Dip and Re-

immersion Method Part is dipped and taken out to solidify, a

white coat will form. Again re-immerse.

Repeat 10-12 layers. Wrap with plastic sheet for 15-20 minutes.

Site- fingers, thumb, wrist, foot, ankle.


8/28

Painting and

brushing method Use painting brush.

Make 6-8 layers of wax. Site- arm, elbow, forearm, wrist,

thigh, knee, shinbone, ankle.


9/28

Bandaging and

Towel Method 4-6gauge bandage is used.

A two folded length one feet ischosen , it is immersed in paraffinwax bath tub then taken out andapplied over the area after releasing

the extra wax. Site:- shoulder, greater trochenter.

DirectPouring or

Bath Method Melted wax of tolerable temperature is

directly poured over the area with cup ormug drop by drop.

10-12 layers.

Wrap in plastic sheet.

Site: elbow, forearm, knee, shinbone,ankle.

METHODS OFAPPLICATION


12/28

Preparation of Patient

Clean the part to be treated.

Check for cuts, rashes, infection, blisters etc.

Position the patient accordingly and comfortably. Explain about the nature of treatment.

Examine the sensation of the patient.

Remove clothing and jewellery etc. Heat should be warm within comfortable limits.

Stay near the patient.


13/28

Preparation of the

Apparatus Wax should be melted.

Temperature : 45 degree.

Do not touch the tub.

Check the temperature before Rx.


14/28

Important Points

Time o f Rx:- 20 minutes

( 15-30 minutes)

Coating:- 2 mm-3 mm per layer;total 9-14 mm thickness.


15/28

Termination

Remove the towel, plastic sheet, wax.

Do not drop wax on the floor.

Inspect and dry the part. Put all the used wax into the tub at the

end of day.

Clean the part with dry cotton.


16/28

Follow up Inspect for erythema, skin colour,

burn.

Warn the patient not to apply ice orcold water till 2 or 3 hrs after the Rx.


17/28

Indications

1. Pain.

2. Spasm.

3. Contracted deformity.4. Adhesive scar.

5. Stiffness.

6. Arthritic joints7. Post-op #.

8. Mobilization of joints.


18/28

Contraindications

Open wounds---delays healing.

Allergic rash

Skin conditions.

Defective arterial blood supply---DVT ,varicose veins.

Impaired skin sensation.

Fever. Malignancy.

Acute injury.


19/28

Advantages

Risk of burns is less ( low specific heat.)

Risk of overheating is less. ( low thermal

conductivity) Best for irregular areas as melted heat is

used.

Oil add moisture. Comfortable.

Cheap.


20/28

Dis-advantages

For distal extremities

No method of temperature control

ones wax is applied.Heating last only for 20 minutes .

Exercises may not be performedsimultaneously.
