CAST CARE FOR BACKSLABS AND FULL CASTS

PLASTER OF PARIS BACK SLAB- initial setting time (working / moulding time) is approximately 3 minutes using cold water.- curing time is 24 - 48 hours in fine weather.- this is a non weight bearing cast.

PLASTER OF PARIS FULL CAST- initial setting time (working / moulding time) is approximately 3 minutes using cold water.- curing, time is 24 - 48 hours in fine weather.- weight bearing after 48 hours with a cast shoe or walking heel.

SYNTHETIC CAST- setting, time is around 7 minutes using cold water.- curing time is 1 hour.- weight bearing / mobilization after 24 hours with a cast shoe or walking heel is preferable.

THINGS TO DO WHILE YOU ARE WEARING A CAST

Elevate the limb in the cast: if you have your arm in a slab / cast, you should wear the slingprovided.If you have a short arm slab / cast, your arm should be in a position higher than your heart.If you have your leg in a cast, you should have it elevated on 2 - 3 pillows, eg; above the level ofyour heart.

Exercise the limb in the cast: if you have an arm slab / cast on you should exercise your fingers,thumb, shoulder and elbow (if your cast allows) as often as possible to control the swelling andpain.If you have your leg in a cast you should exercise toes and knees as much as possible to controlthe swelling and pain.Exercise is a good way to encourage good blood flow in the affected limb.

KEEPING YOUR BACKSLAB / CAST DRY

Do not wet Your Backslab / Cast - if Plaster of Paris becomes wet, it will soften and its condition willrapidly deteriorate.-Unlike Plaster of Paris casts, a synthetic cast will not be affected by moisture.However, the stockinette and the synthetic padding will retain the moisture and the skinunder the cast will macerate quickly. Areas most affected are the palm of the hand and the soleof the foot.

A plastic bag on its own is not an effective solution, as there will be:a) a condensation build-up inside the bagb) water will still pass the edge of the bag, regardless of how well it is sealed.

Preferred Procedure:

a) wrap a towel around the cast - this will absorb most excess moistureb) when applying, the plastic bag use a double tape system (electrical tape) at top of the bag. Thefirst wrap of tape overlapping onto the towel underneath, the second wrap of tape approximately2cm above first wrap of tape.

If your cast gets wet you should contact your local Doctor or the Plaster Technician at yourlocal hospital. They will advise you how to assess the wetness of your cast. If a cast get wet orcracks or softens it may not be doing the job it is supposed to (immobilise the limb). Youmay need to have a new cast applied.

GUIDELINES FOR INTRAVENOUS REGIONAL ANAESTHESIA(BIER’S BLOCK)

INDICATIONS:The reduction of upper limb fractures or dislocations. Minor surgical procedures in the upper limb.Suitable for children old enough to co-operate with and comprehend an explanation of theprocedure.

CONTRAINDICATIONS:unstable epilepsyuncontrolled hypertensionsevere liver diseasesickle cell diseasesecond or third degree heart blockperipheral vascular diseaseallergy to amide local anaesthetics

PATIENT PREPARATION:Informed consent should be obtained. The patient should ideally be fasted for 4-6 hours. IVRAmay be performed in non-fasted patients. Wherever possible one physician should supervise IVRAand a second physician should perform the procedure. The patient’s blood pressure should bechecked beforehand in the uninjured limb. Webril should be applied from the axilla to the anticubitalfossa of the injured limb ensuring access to the brachial artery. The cliff should then be appliedsnugly over the Webril.

MONITORING:Monitoring should ideally consist of continuous ECG monitoring, continuous pulse oximetry andintermittent non-invasive blood pressure monitoring.

LOCAL ANAESTHETIC:Prilocaine is the ideal local anaesthetic for IVRA. The dose is 3mg/kg of 0.5% Prilocaine, or amaximum adult dose of 200mg or 40mls x 0.5% Prilocaine. Single dose preservative freePrilocaine should be employed.

In the absence of Prilocaine a low dose technique with Lignocaine may be employed. The regimeis as follows:- for those under 14 years old and over 65 years old, 1.5mg/kg of 1% Lignocaine,maximum dose 100mg. For those 14 to 65 years old, 100mg of 1% Lignocaine. This should bediluted to a 0.5% solution with an equal volume of normal saline. If after 15 minutes adequateanaesthesia is not present an equivalent amount of saline may be injected which often enhancesthe block, otherwise in children and the elderly an additional 0.5mg/kg of .5% Lignocaine may beinjected. In adults an additional 50mg of 0.5% Lignocaine may be given as a repeat dose. ThisLignocaine regime should only be employed where Prilocaine is unavailable.

PROCEDURE:

Step l: Check all equipment connections and cuffs for leaks. Ensure you are familiar with cuffoperation.

Step 2: Ensure access to resuscitation equipment, drugs, oxygen supply and suction. Wherepossible employ continuous ECG, pulse oximetry and non-invasive blood pressure monitoring.

Step 3: Insert intravenous cannulae into both limbs, as distally as possible in the injured limb.Flush both cannulae with sterile saline to ensure patency.

Step 4: Exsatiguinate the limb by elevating for 2-5 minutes with direct occluding pressure over thebrachial artery.

Step 5: Inflate the upper tourniquet rapidly to systolic blood pressure + 100mmHg. Physicallyensure that the cuff is inflated and check for absence of the brachial or radial pulses.

Step 6: Inject 0.5% Prilocaine 3mg/kg or a maximum of 40mls x 0.5% Prilocaine (200mg)intravenously over 2 minutes. There is no need to employ a test dose.

Step 7: Assess for adequate anaesthesia which may take anywhere from 5-20 minutes. Observethe patient for:-

restlessnesslightheadednessdizzinesstinnitusparaesthesiamuscular excitationseizurehypotensionbradycardia

Inflate the lower tourniquet to systolic blood pressure + 100mmHg. Physically ensure inflation anddeflate the upper cuff. Finally, physically ensure that the lower cuff is inflated and that the inflationpressure is correct before proceeding.

Step 8: A second physician should then perform the procedure. If a repeat x-ray is required, thepatient should be carefully moved to x-ray with the cuff still inflated. The cuff should not be deflateduntil the repeat x-rays have been reviewed.

Step 9: Deflate the cuff no earlier than 20 minutes after completion of the injection of Prilocaine.There is no need to sequentially deflate and inflate the cuff.

Step 10: For at least 15 minutes after tourniquet deflation observe the patient for theabovementioned side effects and the return of normal sensation.

RADIAL THUMB SPICCA SLAB

Materials required:15cm Plaster of Paris slab material 15ply1 x 7.5cm natural padding1 x 5cm conforming bandage1 x 5cm light crepe bandagecold water

Procedure1. Set up work area. Ensure all materials have been removed from packaging and within reach.

2. Calculate length of slab, from base of thumb nail or proximal to IP joint and distal to elbowcrease (Fig 2).

3. Fold slab material three times to length required to achieve 15ply.

4. Mark and cut out template (Fig 1).

5. Apply padding to limb. Apply padding circumferentially around limb; overlapping, 1/2 width padding per wrap; to provide an even/flat bed for plaster. Ensure padding extends 1 - 2cm past expected distal/proximal edge of plaster, to act as turn back’.

6. Run slab material through water; then ‘strip’ excess water from material between thumb andindex finger. This reduces mess and evenly distributes plaster through slab material.

7. Apply slab onto radial aspect of arm; align distal edge of slab with palmar crease, ensuring slab material rests at base of thumb nail (Fig 2).

8. Quickly shape slab material to arm.

9. Secure slab while still wet with conforming bandage. The conforming bandage secures slab to limb. The conforming bandage also becomes impregnated into the Plaster of Paris, therefore adding strength to the slab.

10. Turn padding back to form soft edges. Ensure MCPs have full range of movement.

GUTTER SLAB

Materials required:15cm Plaster of Paris slab material 15ply1 x 7.5cm natural padding1 x 5cm conforming bandage1 x 5cm light crepe bandagecold water

Procedure1 Set up work area. Ensure all materials have been removed from packaging and within reach.

2 Calculate length of limb/cast from 5th PIP joint to 4-5cm distal to elbow crease (Fig. 2).

3 Fold slab material three times to length required to achieve 15ply.

4 Mark and cut out template (Fig. 1).

5 After reduction and while maintaining traction, apply two layers of padding between 4th and 5th fingers, continue around fingers and circumferentially around limb; overlapping 1/2 width padding per wrap; to provide an even/flat bed for plaster. Ensure padding extends 1 - 2cm past expected distal / proximal edge of plaster to act as ‘turn back’. Ensure bony areas are well padded.

6 Place moulding pads (Fig 4). Moulding pad (Fig. 4-1) is approximately the length and width of your thumb pad and ispositioned over the metacarpal heads on the volar aspect side of the hand. This reduces the riskof pressure areas caused by pressure moulding when cast is applied. Moulding pad (Fig 4-2) is approximately the size of two finger width square, this pad is positioned over the proximal end of the metacarpal on the dorsal aspect of the hand.

7 Run slab material through water; then ‘strip’ excess water from material between thumb andindex finger. This reduces mess and evenly distributes plaster through slab material.

8 Keeping arm in a vertical position; apply slab evenly along the Ulna border, starting at the PIPjoints with the tapered end of the slab, smooth and shape slab to arm.

9 Secure slab while still wet with conforming bandage. The conforming bandage secures slab for moulding. The conforming bandage also becomes impregnated into the Plaster of Paris,therefore adding strength to the slab.

10 Turn padding, back to form soft edges. Ensure distal and mid phalanxes have full range of movement.

11 While slab material is setting you must apply moulding in the direction shown in (Fig. 4 - 1 & 2). You must ensure MCP’s are at 90 degrees and that the wrist is in a neutral position. Do notrelease pressure until slab material is set! (approx. 3 minutes).

12 Apply light crepe bandage snugly. The light crepe bandage can be changed or loosened/tightened as required.

13 Ensure patient knows to exercise and elevate limb, to minimise swelling and pain.

14 Place arm in high arm sling.

SCAPHOID SLAB

Materials required:

15cm Plaster of Paris slab material 15ply1 x 7.5cm natural padding.1 x 5cm conforming bandage1 x 5cm light crepe bandage cold water

Procedure

1 Set up work area. Ensure all materials have been removed from packaging and within reach.

2 Calculate length of slab, from base of thumb nail or proximal to IP joint and distal to elbowcrease (Fig 2).

3 Fold slab material three times to length required to achieve 15ply.

4 Mark and cut out template (Fig 1).

5 Apply padding, to limb. Apply padding, circumferentially around limb; overlapping, 1/2 width padding per wrap; to provide an even/flat bed for plaster. Ensure padding extends 1 - 2cm past expected distal/proximal edge of plaster, to act as ‘turn back’.

6 Run slab material through water; then ‘strip’ excess water from material between thumb andindex finger. This reduces mess and evenly distributes plaster through slab material.

7 Supinate patients forearm.

8 Apply slab onto volar aspect of arm; align distal edge of slab with palmar crease, ensuring slab material rests at base of thumb nail (Fig. 2).

9 Quickly shape slab material to arm.

10 Secure slab while still wet with conforming bandage. The conforming bandage secures slab for moulding. The conforming bandage also becomes impregnated into the Plaster of Paris,therefore adding strength to the slab.

11 Turn padding back to form soft edges. Ensure MCPs have full range of movement.

1 Set up work area. Ensure all materials have been removed from packaging and within reach.

2 Calculate length of limb/cast, from MTH’S to within 5cm from groin. Check length of slab on the good leg to avoid unnecessary discomfort to the patient.

3 Using 15cm slab material fold double required length to achieve 10ply.

4 Position patient on pillows (Fig. 1)

5 Apply padding to top of leg. Lay padding on top of leg - 2-3 layers thick. (Fig. 1a). Allow a smallcap between leg and bed to allow a half roll of padding through (Fig. 1b)

6 Run slab material through water, then ‘strip’ excess water from material between thumb and index finger. This reduces mess and evenly distributes plaster through slab material.

7 Apply slab material to the top of the leg, smooth out slab material to conform to the leg and allowslab to set (Fig. 2).

8 Secure top slab with padding at proximal and distal ends of limb (Fig. 2a - 2b). This splints thelimb to allow lifting for the second part of the slab to be applied.

Bottom Slab

1 Calculate length of limb/cast, from MTH’s to within 5cm from groin on the under side of the limb. This slab will be slightly longer than top slab. Check length of slab on the good leg to avoid unnecessary discomfort to the patient.

2 Using 20cm slab material, fold double required length to achieve 10ply.

3 Lift leg, supporting the leg.

4 Apply padding circumferentially around limb and top slab, overlapping 1/2 width padding perwrap; to provide an even/flat bed for the plaster slab. (Fig. 3).

5 Run slab material through water, then ‘strip’ excess water from material between thumb and index finger. This reduces mess and evenly distributes plaster through slab material.

6 Apply slab material to the bottom of the leg (Fig. 4).

7 Secure the slab material with padding, covering both slabs (Fig. 5).

8 Apply the light crepe bandage over the limb, this will act as a neat finish at the same time keepingall parts of the slab in place.

Uses for the Sandwich Slab:

- Temporary splint - displaced and non – displaced # of Tibia and Fibula

- This slab can be sealed with FIBREGLASS if the # is in good alignment and an operation isnot required and swelling has subsided

NOTE:These slabs do not overlap - this slab is designed to have an open edge to allow for swelling (Fig.5).

CAST SPLITTING

Equipment required:

Cast cutting saw

Small spreaders

Bandage scissors

Roll of 7.5cm Cotton padding

Light crepe bandage

PROCEDURE

1. Make a cut along appropriate border with saw. Arm cast’s, are always split on the opposite side of #, EG. Radial # - cut along ulna border. Theonly exception is a long arm cast - a long arm cast is always split to point of the elbow onthe ulna border. Leg cast’s are split just off center of the Tibial blade.

2. Gently open slit (approximately 1cm with spreaders). Allow split to close slightly.

3. Cut padding with bandage scissors so the skin can be seen along the full length of the split.

4. Lay a length of padding 6ply the same length as the cast along the split. Next, gently and evenly pack the padding into the split using the blade of the spreaders. This will: a) hold the split open

b) prevent, the skin from swelling into the split.

5. Apply light crepe bandage around cast. This is done to: a) to prevent the split from opening further.

b) to keep the padding in the split intact. c) to prevent the patient from interfering with both of the above.

TRIMMING PLASTER OF PARIS AND SYNTHETICSHORT ARM SLABS / CASTS

Trim to allow full flexion and extension of digits and elbow.

The distal end of the cast should:a) finish proximal to the metacarpal heads. Fig. 1Ab) along the palmar crease Fig. 3Bc) allow easy circular motion of the thumb Fig. 3CCast material between the thumb and index finger Fig. 1C should not impair theability of all fingers to oppose the thumb Fig. 3.

The proximal end of the cast should allow full flexion an extension of the elbow Fig. 2D.Remember that excessive trimming could hinder immobilisation of the fracture.

Note:After trimming a Plaster of Paris cast, turn back padding and apply a strip of adhesive tape completely aroundthe trimmed edge to prevent flaking of the trimmed areas.After trimming a synthetic cast, turn the padding and stockinet back over the edge and seal using adhesivetape.

KNEE IMMOBILISER SPLINT

Ensure that the central contoured area of the splint is directly around the outside edge of thePatella.

The straps on either side of the knee should be placed on and tightened first, this gives stability tothe injured area.

Straps should be firmly in place around the Patella to maximise support of the knee.

Check tightness regularly to minimise circulatory problems.

Limb should be elevated and foot exercised regularly, to relieve swelling and pain.

Uses for the Knee Immobiliser

Temporary splint for: # Patella Dislocated Patella Soft tissue damage Ligament damage Pain control
