otic self care Flashcards
background
- self care should be restricted to minor external ear disorders of the auricle and the external auditory canal (EAC)
- FDA approved self care otic conditions: excessive cerumen, water-clogged ears
- water clogged ear is different than externa otitis (Swimmer’s Ear)
excessive/impacted cerumen
- cerumen = earwax, a naturally occurring substance that assists in the defense of the external ear canal to clean, protect, and lubricate the EAC
- cerumen impactation = lodged, wedges, or firmly packed cerumen in the EAC
factors that can disrupt the normal flow of cerumen toward the outer EAC
- anatomic variability = narrow or irregularly shaped EAC
- atrophy of the ceruminous glands: aging, genetic tendencies
- irritation from foreign objects (hearing aids, ear plugs, or use of cotton-tipped swabs)
- presence of excessive hair
excessive/impacted cerumen clinical presentation
- signs/symptoms: sensations of ear fullness, dull pain, itching, discomfort, tinnitus (ringing in ears), dizziness, vertigo, cough, hearing loss, hearing aid malfunction or feedback
- occasionally present: ear discharge and an odor
excessive/impacted cerumen clinical impact
- transient hearing loss, especially in the elderly
- inappropriate methods of removal of excessive or impacted cerumen including use of cotton swabs can push wax deeper into the ear or damage the EAC or tympanic membrane, potentially resulting in otitis media
excessive/impacted cerumen exclusions for self care
- signs of infection (irritation, rash)
- pain associated with ear discharge
- bleeding or signs of trauma
- presence of ruptured tympanic membrane
- ear surgery within prior 6 weeks
- tympanostomy tubes present
- incapable of following proper instructions
- hypersensitivity to recommended agents
- <12 years of age
- worsening of condition after attempted self care
excessive/impacted cerumen treatment goals
- remove cerumen using safe, effective, appropriate products while preventing potential adverse events
- reduce signs/symptoms
excessive/impacted cerumen self care
- the use of cerumen-softening agents with or without irrigation
- caution is warranted with patient attempts associated with greater risk of EAC damage
- if presence of excessive cerumen is asymptomatic , active management/removal is optional
excessive/impacted cerumen non-pharmacologic treatment
- earwax should only be removed when it has migrated to the outermost portion of the EAC
- don’t insert objects into the ear to remove earwax - may injure the ear canal or push the wax further into the canal
- IMPACTED cerumen removal should only be done by a properly trained PCP
- never use an ear candle to remove earwax
excessive cerumen non-pharm treatment methods
- warm water irrigation with a bulb syringe, using sterile water
- use a wet washcloth draped over a finger to remove earwax from the outer canal
- caution against use of Curette (ear cleaning tool), etc.
- home jet irrigation not recommended
excessive/impacted cerumen pharmacologic treatment
-currently only FDA-approved nonprescription earwax-softening agent is carbamide peroxide 6.5% in anhydrous glycerin
excessive/impacted cerumen special populations
- nonprescription cerumen-softening agents are ONLY approved for patients >12 years old
- no special consideration for use is necessary in pregnant or lactating women or in older adult
cerumen-softening products
- carbamide peroxide 6.5% in glycerin
- used alone or in combo with warm water irrigation to remove loosened cerumen
- only for use in ages >12 for OTC use
- other products used off-label products include hydrogen peroxide docusate - NOT RECOMMENDED
carbamide peroxide 6.5% in glycerin MOA
- carbamide peroxide: weak antibacterial effect and mechanical loosening of cerumen when carbamide peroxide is exposed to moisture, and hydrogen peroxide and oxygen releases slowly
- anhydrous glycerin: softens and penetrates cerumen to help loosen excessive earwax
cerumen softening products administration
-may be administered twice daily for up to 4 days
