[Evaluation of factors associated with postoperative sore throat]
Background:
Postoperative sore throat should be recognized seriously as an avoidable complication because of high incidence and dissatisfaction with anesthesia. The aim of the study was to identify the risk factors of postoperative sore throats in patients undergoing general anesthesia.
Methods:
We retrospectively studied 1,733 patients (above 18 years of age) who had undergone general anesthesia from January to December 2010 and who had visited Department of Anesthesia, postoperative anesthesia clinic.
Results:
Age, ASA classification, position, airway device, methods of postoperative pain management and site of surgery were significantly identified as the associated factors for postoperative sore throat using univariate analysis. Under 65 year of age (odds ratio 2.3), operation of head and neck and pharynx (odds ratio 1.6), spine surgeries (odds ratio 0.33), laryngeal mask (odds ratio 0.47), and postoperative intravenous patient-controlled analgesia (IV-PCA, odds ratio 0.4) were significantly identified as the factors with multivariate studies.
Conclusions:
Six associated factors for postoperative sore throat were identified in this study.

Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
Tonsillitis I: Introduction
Etiology
Three primary contributing factors have been identified.
Acute Pharyngitis
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:
Factors Affecting the Risk of Infection
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...
