Pharyngitis is inflammation of the pharynx or back of the throat. It is commonly known as a sore throat and is usually caused by viruses. The most common type is acute pharyngitis caused by adenovirus, coronavirus or streptococcus bacteria. Chronic pharyngitis is a persistent inflammation that can be caused by irritants like dust, smoke or excessive voice use. Symptoms include pain on swallowing, fever and redness of the throat. Diagnosis involves examination of the throat and testing of secretions. Acute cases usually resolve within a week with pain relief and fluids, while antibiotics may be used for bacterial infections. Chronic pharyngitis management focuses on removing irritants and relieving symptoms

ACUTE PHARYNGITIS
It is a sudden, painful inflammation of the throat.
ETIOLOGY
1. Virus: Most common cause (90%) of sore throat. Adenovirus, coronavirus,
Homophiles influenza, Mononucleosis. They do not respond to antibiotic
therapy.
2. Bacterial: Less common cause of sore throat. Strep throat is a common
bacterial infection of pharynx caused by Group A beta hemolytic
streptococci(GAS). Other bacteria are mycoplasma Pneumoniae, Neisseria
meningitis etc.
RISK FACTORS

2. Allergies
3. Frequent sinusitis
4. GERD
5. Exposure to secondhand smoke.
PATHOPHYSIOLOGY

2. CLINICAL MENIFESTATIONS
1. Fiery red pharyngeal membrane and tonsils.
2. Fever(101 F)
3. Malaise
4. Sore throat pain ( In case of GAS bacteria)
5. Swollen , erythomatous tonsils
6. Halitosis.
DIAGNOSTIC EVALUATION
1. History taking
2. Physical examination
3. CBC
4. Throat swab culture.
5. Rapid streptococcalantigen test.
MEDICAL MANAGEMENT
Uncomplicated viral Pharyngitis infections subside promptly within 3 to 10
days after onset. Viral Pharyngitis is treated with supportive measures because
antibiotics have no effects on the causative agents.
A. PHARMACOLOGICAL THERAPY: In case of bacterial
Pharyngitis Penicillin is the treatment of choice and given for 5 days. Patient
who are allergic to penicillin and erythromycin, they are treated with
Cephalosporin and macrolides. Severe sore throat can be relieved by
analgesics such as Aspirin, Acetaminophen. If required acetaminophen with
codeine can be taken three to four times daily. Some patients find slat-water
gargling to be soothing. In severe cases, Gargles with benzocaine may
relieve symptoms.
B. Nutritional therapy: A liquid or soft diet is provided during the acute
stage of the disease. Sometimes throat is so sore that liquid can not be taken
in adequate amount. In severe situations IV fluids may be needed. Otherwise
patient is encouraged to drink as much fluid as possible.

common in the adults who work in dusty surroundings, use their voice to
excess, suffer from chronic cough or habitually use alcohol and tobacco.

wall.
CLINICAL MENIFESTATIONS
1. Sense of irritation and fullness in the throat.
2. Mucus buildup which is expelled out by coughing.
3. Nasal congestion
4. Dysphagia.
MANAGEMENT
 Nasal congestion is relieved by short term use of nasal sprays or
medications containing ephedrine sulphate.
 For a patient with a history of allergy , antihistamine decongestants
such as Pseudoephedrine is prescribed orally every 4 -6 hours.
 Aspirin or acetaminophen is recommended .
 For adults with chronic Pharyngitis, tonsillectomy is an effective
option.
NURSING MANAGEMNT
