1 Infection: Otitis Media
Ricci, pp

2 Etiology Most common in childhood—usually in first 24 mos
Viral or bacterial (Haemophilus, Streptococcus,or Moxarella) infection of middle ear with inflammation of canal and eardrum Usually preceded by URI, RSV specifically, or flu

3 Pathophysiology Infection travels thru nose or throat and goes up eustachian tube Blocked eustachian tubes from edema or enlarged adenoids fail to drain middle ear Tubes can become contaminated from reflux, aspiration, sneezing, blowing nose

4 Risk Factors Normally small, short airways and eustacian tubes
Family hx Second-hand smoke—causes pathogens to attach to middle ear Day care or other crowded settings

5 Risk Factors Otitis media with effusion Malfunctioning eustacian tube
Horizontal feeding Limited exposure or immunity Hx allergies, cleft palate, Down syndrome

6 Manifestations Purulent matter and fluid collection causes bulging and pain; popping sensation, pressure. Sudden relief of pain may indicate perforation. Fever Otitis media with effusion may have no overt sx

7 Otoscopic Exam Otoscopic exam reveals loss of light reflex and bony landmarks; bulging, red, immobile eardrum; bubbles behind eardrum with serous (OME) Tympanogram is flat

8 Antibiotic Treatment All children < 6 months old because of immature immunity All children > 6 mos if severe illness Med choices: Amoxicillin mg/kg/d bid x 5-7d If allergic—azithromycin, cephalosporins IM Rocephin for resistance or noncompliance (use with lidocaine if approved by HCP) Viral types need no antibiotics—resolve spontaneously

9 “Watchful Waiting” In all children over 6 mos, if fever and pain are not present, then observation is OK x 72h. No antibiotics are needed if improved

10 Supportive Care Analgesic/antipyretic
Benzocaine or herbal ear drops (Allium sativum, Verbascum thapsus, Calendula flores, Hypericum perforatum, lavender, and vitamin E) Topical pain relief with heat

11 Complications Repeated & resistant cases and persistent perfusion and hearing loss may require myringotomy with placement of tympanostomy tubes and possible adenoidectomy Perforation—may need patching Meningitis Mastoiditis Hearing loss, speech delay

12 Nursing Responsibilities
Pain relief with supportive care Manage ear drainage Encourage parent to give child all of medication Encourage immunizations esp. PCV and Hib, influenza Follow orders and educate regarding management of tubes Refer children who have hearing loss

13 Parent Education Causes of infection S/S of infection
Prevention—breastfeeding, no smoking, no bottle propping, feeding in semi-reclining position, stay away from people with URIs, xylitol Recognition and prevention of complications Med administration Avoid air travel

14 Infection: Conjunctivitis
Ricci, pp

15 Etiology & Pathophysiology
Most common eye disease Inflammation of the conjunctiva Viral, bacterial, allergic, foreign body Viral caused by adenoviruses and influenza Bacterial called “pink eye” and caused by Staph, Haemophilus, or Strep. In newborn, Chlamydia or Gonorrhea Allergic is usually seasonal, bilateral,and occurs more in older children and teens

16 Risk Factors Newborn, esp in first 2 wks Crowds—day care, school
URI—cold, pharyngitis, otitis

17 Manifestations Redness Edema Pain, scratchy or itchy feeling
Mild photophobia Watery or purulent drainage

18 Diagnostics Most are not cultured C & S for bacterial or viral
Conjunctival scrapings can also detect microorganisms Fluorescein dye to detect FBs and trauma

19 Treatment Eye drops for newborns to prevent Chlamydia and gonorrhea
Topical anti-infectives applied as eye drops or ointments usually erythromycin, gentamicin, or penicillin, acyclovir Severe cases require systemic tx Antihistamines, either gtts or po for allergic

20 Supportive Care Warm or cool compresses Cleaning away drainage
Eye irrigations Analgesics Avoid bright lights, reading Sunglasses No contact lenses

21 Parent Education Prevent spread of bacterial—wash hands, don’t share stuff, don’t return to school until 24h of med With allergic, make sure child irrigates eyes and washes hands when he comes in. Shower and wash hair before bedtime.

22 Parent Education How to do eye drops Wash hands before eye drops
Don’t contaminate eye dropper Reduce lighting No reading
