URT conditions and infections I Flashcards
Describe rhinitis
Inflammation and swelling of the
mucous membrane of the nose,
* Characterized by a runny nose
and stuffiness
What causes rhinitis? list the symptoms
- Usually caused by the common
cold or allergy. - Symptoms: runny nose, sneezing,
and stuffiness.
Duration of allergic/viral rhinitis
2-3 days. May extend to 5-7 days
Duration of bacterial rhinitis
7-10 days
Symptoms of viral/allergic rhinitis
Nasal congestion / obstruction,
Watery discharge (rhinitis) from
BOTH nostrils, general illness
Symptoms of bacterial rhinitis
Headache, fever,
facial/dental
tenderness (facial
pain), purulent nasal
discharge (especially
unilaterally)
Common bacteria causing rhinitis
Streptococcus pneumoniae
Haemophilus influenza
Moraxella catarrhalis
Explanation of allergic rhinitis
Inflammation of the mucous membranes of
the nose and paranasal sinuses in response
to an allergen e.g. pollen, house dust,
grasses, and animal hair.
Signs and symptoms of allergic rhinitis
Characterised by recurrent episodes of:
* blocked stuffy nose
* watery nasal discharge
* frequent sneezing, often accompanied by nasal
itching and irritation
* conjunctival itching and watering
* oedematous pale nasal mucosa
* mouth breathing
* snoring at night
What other things can cause similar symptoms as allergic rhinitis?
such as infections,
vasomotor (non-allergic) rhinitis, overuse of decongestant
drops, and side effects of antihypertensives
and antidepressants.
Non-drug treatment of allergic rhinitis
Avoid triggers/allergens
Pros and cons of using antihistamine in allergic rhinitis
Relieve the itching, sneezing, and runny nose of allergic rhinitis, but
they do not relieve nasal congestion.
How to make up for the cons of antihistamine use in Tx of allergic rhinitis?
Using them along with nasal steroids or decongestants may provide
greater symptom relief than using one of these medications alone.
What medication is most effective in Tx of allergic rhinitis
Topical intranasal steroids are the most effective, evidence-based
maintenance therapy
Adv. Effects of topical steroids
Adverse effects: transient burning, stinging, dry nose, or sneezing
How long do topical intranasal steroids take to work optimally?
Maximal response only seen after 2 weeks of treatment i.e.
continuous, prophylactic use, even when symptom free.
Pt education on how to use topical intranasal steroids
Usually administered as sprays, blow nose before administration,
spray away from the nasal septum, while breathing in gently (do not
sniff up the spray), bend head forward towards the knees for 20
seconds, while occluding the nose to prevent leakage out the nose
Drugs to use in allergic rhinitis Tx in adults and children>6yrs
Corticosteroid, e.g.: Fluticasone, aqueous nasal solution
drug used for short term relief from allergic rhinitis
Chlorphenamine, oral, 6–8 hourly.
Tx for relief of nocturnal nasal blockage
Topical nasal decongestant e.g.:
* Oxymetazoline 0.05%, intranasal, administered at night for a maximum of 5
days
long term drug tx of allergic rhinitis in both adults and children
Cetirizine, once daily
What is a special caution with regards to antihistamines in terms of age?
Do not give children <2yrs
When should you refer a pt with allergic rhinitis?
- Chronic persistent symptoms.
- Severe symptoms.
- Patients on protease inhibitors, requiring nasal corticosteroids.
How long do colds last?
usuallybegin to resolve in 3 days. But may last up to 14 days in some cases
Who is at risk of complications from colds?
Malnourished children, the elderly and debilitated patients
Complications pf colds
Secondary bacterial infections, including:
* pneumonia
* otitis media
* sinusitis
General considerations for viral rhinitis
Limit strenuous activity.
* Ensure adequate hydration.
* Advise patient to return to clinic if earache, tenderness or pain over
sinuses develops or symptoms persist for > 14 days.
Drug tx for viral rhinitis
Symptomatic treatment for pain, fever and nasal congestion
* 0.9% saline (NaCl) nose drops: relieves dryness, liquefies mucus
* Pain & fever: paracetamol, aspirin, ibuprofen = antipyretic analgesics
Antibiotics – only if Bacterial infection!
List nasal decongestant drugs(4)
Oxymetazoline
* Phenylephrine
* Xylometazoline
* Pseudoephedrine
MOA of nasal decongestants
ɒ1 agonists: Phenylephrine, oxymetazoline, (pseudoephedrine)
* Mechanism of action: stimulate alpha rec on nasal arterioles, causing
constriction, less blood flow, less mucous produced.
what happens when you overuse nasal decongestants?
could damage the nasal mucosa and cause
rebound nasal congestion
Inhaled treatments for URTIs and allergies
Inhaled Moisturisers i.e. vaporisers , humidifiers and steam inhalants.
* Inhaled decongestants – Eucalyptus oil, Friar’s balsam
* Bronchodilators and / or corticosteroids – Multidose inhalers and
nebulisers
Combination drugs for URTIs and allergies
Antihistamines + sympathomimetics + analgesics
