  1. Nursing the person with a C a s t

  2. Home Page Table of contents • Learning outcomes • Plaster or fiberglass cast? • Caring for a drying cast • Cast complications • i. Nursing assessments • ii. Nursing actions • Teaching materials for persons with a cast • Quiz • Glossary

  3. Learning Outcomes • 1. Compare & contrast plaster & fiberglass casts • 2. Explain the care required while a plaster cast dries • 3. For each complications associated with a cast describe • i. nursing assessments required to detect • ii. nursing actions to treat the complication • 4. Be familiar with teaching materials available for persons who have a cast

  4. fiberglass casts has durability of plaster but is lighter weight hardens within minutes is porous and  there are fewer skin problems does not soften when wet - hair dryer quickly dries skin beneath Costs more plaster casts inexpensive heavy sets in ~ 3 -1 5 minutes, then takes 24 - 72 h to dry (varies with thickness) messy to apply gives more support for ‘bad breaks’

  5. Care required while the plaster cast dries • once applied heat is given off for ~ 15 minutes & may be uncomfortable • while the plaster sets, the cast will remain soft & touching may lead to indentations which may then create pressure spots • until dry  handle the cast with palms of hands only - not fingers do not rest cast on hard surfaces or sharp edges

  6. Drying a plaster cast • Picture to be inserted

  7. Presentation on-lineapplication of a fiberglass cast to see click here note the use of 1. Stockinette 2. Padding 3. Casting material

  8. Potential Complications • hidden bleeding • neurovascular compromise • compartment syndrome • skin &/or tissue breakdown • hidden infection from wound &/or ulcer

  9. Bleeding may occur beneath a cast if • there is trauma to the skin at the time of injury • surgery is required to reduce the fracture • this will be documented asORIF • open reduction & internal fixation

  10. To detect bleeding • visualize the cast carefully. Give particular attention to • areas over known wounds &/or incisions • dependent areas - remember that liquid flow follows the line of gravity

  11. Typical appearance (& terminology to describe) • @ 1000 hours Sanguineous Sero-sanguineous @ 1200 hours serous @ 1400 hours

  12. If you see bleeding Mark the outer edges of the bleeding area with time and date & then initial Example: JW Jan 10 - 1000 1200 JW 1400 JW Then ---- >

  13. Follow-up • continue to monitor • instruct client to call you if additional bleeding is noted &/or if s/he notices any other changes • notify MD if • bleeding continues • there is a significant change in vital signs • client condition changes

  14. Document in narrative notes & indicate size location vitals other signs of bleeding Narrative Notes 0845 dark red area ~ 3 cm diameter noted over outer aspect of malleolus; P 88, R 24, BP 108/56; alert but pale; 0930 slight extension of bleeding; client states “feel fine” 1030 no further bleeding noted; P 80 BP 120/ 66 ; instructed to call nurse if further bleeding noted JWladyka RN

  15. Neurovascular Compromise Compression of nerves and blood vessels may be caused by • swelling 2° to injured tissue • impinging bone pieces • swelling 2° to surgery • restrictive pressure 2° the cast

  16.  by doing C S M C colour plus  • capillary refill (normal < 3 sec) • pulse in affected extremity • [whether present -- no need to count] • temperature of skin S sensation -- do not use a sharp object to assess M able to move extremity & digits

  17. Frequency of C S M • assess q2h X 8, then q4h X 48, then q 8 h • at first sign • elevate limb > heart • give analgesia • if symptoms persist notify MD stat as compartment syndrome may be occurring

  18. If swelling persists • the physician will order the cast to be bivalved • Note - Bivalving may be done by • a physician • an orthopedic technician • a specially trained nurse Burrell et al; 1586

  19. Compartment Syndrome - a special form of neurovascular compromise • muscles, nerves & blood vessels are enclosed in though inelastic fascia (or compartments) • if the muscle within a compartment becomes swollen it cannot stretch & thus the nerves and blood vessels are compressed

  20. Signs & Symptoms • deep, throbbing, unrelenting pain • not controlled by analgesics • often seems out of proportion to the injury • swollen and hard muscle • diminished capillary refill, cyanotic nailbeds, obscured pulse • parasthesia, paralysis

  21. To reverse compartment syndrome A fasciotomy is performed Burrell et al; 1590

  22. Skin &/or tissue breakdown Is most likely if the • cast is resting too close to the tissue -- particularly over boney prominences • cast edges are sharp and irritating the skin

  23. The cast over the area may become warm d/t inflammation beneath if there is skin breakdown there might be drainage if the area becomes infected there may be an odour Diagram to be added Monitor Pressure Areas

  24. Windowing a cast Using cast cutting equipment • an orthopedic tech • MD, or • specially trained nurse cuts out a piece of the plaster over the area of concern if required a dressing is applied Picture to be added

  25. Finishing a cast • If the edges are not covered with stockinette, then you may need to cut small pieces of tape to smooth over the edges -- this is referred to petalling the cast Burrell et al; 1591

  26. Teaching information r/t cast care • Virtual Hospital: Iowa Health Book: Orthopaedics: Instructions for Patients Wearing a Cast
