Sputum Studies II: Culture and Sensitivity01:20

Sputum Studies II: Culture and Sensitivity

318
Description
Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...

Suctioning the Nasopharyngeal Airway

407
Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.

Chronic Pharyngitis01:23

Chronic Pharyngitis

2.1K
Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
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,...

Area of Science:

  • Otorhinolaryngology
  • Microbiology
  • Infectious Diseases

Background:

  • Rhinosinusitis is an inflammatory condition of the nose and paranasal sinuses, often involving a pathogenic role for microorganisms.
  • Microbial interactions with the mucosa and environment shape the bacterial ecosystem in rhinosinusitis.
  • While antibiotics are common for rhinosinusitis, sensitivity-directed prescriptions are infrequent.

Purpose of the Study:

  • To identify the microorganisms responsible for rhinosinusitis.
  • To determine the antibiotic sensitivity patterns of nasal microbiota in patients with rhinosinusitis in the region.

Main Methods:

  • A 6-month prospective study (March-September 2022) included 100 patients diagnosed with rhinosinusitis.
  • Nasal swabs were collected via diagnostic nasal endoscopy from the middle meatus for culture and sensitivity testing.
  • Data from adult and pediatric patients with acute, chronic, and recurrent rhinosinusitis were analyzed.

Main Results:

  • Staphylococcus aureus was the most common isolate in chronic (56%) and recurrent (66%) rhinosinusitis, while Klebsiella (28%) was most common in acute cases.
  • Klebsiella showed sensitivity to beta-lactams and quinolones.
  • Staphylococcus aureus demonstrated sensitivity to beta-lactams and cephalosporins.

Conclusions:

  • Antibiotic resistance is increasing due to widespread antibiotic use.
  • Judicious, sensitivity-directed antibiotic usage is essential to reduce the risk of antibiotic resistance.
  • Targeted antibiotic therapy minimizes unnecessary drug exposure and improves patient outcomes.
