Abstract

Insights

Reusable nasal spray devices pose cross-contamination risks. Microbiologic analysis revealed methicillin-resistant coagulase-negative staphylococci in cultures, indicating a need for enhanced safety measures in otolaryngology.

Area of Science:

  • Otolaryngology
  • Microbiology
  • Infection Control

Background:

  • Reusable nasal spray devices are common in otolaryngologic exams.
  • Concerns exist regarding cross-contamination risks associated with these devices.
  • This study investigated the safety of pump-type atomizers after repeated use.

Purpose of the Study:

  • To assess the microbiologic safety of reusable positive-displacement nasal spray devices.
  • To evaluate the effectiveness of prophylactic measures against contamination.

Main Methods:

  • Microbiologic analysis of a reusable nasal spray bottle, pump, and tips used on 282 patients.
  • Comparison of two prophylaxis methods (protective caps, alcohol rinsing) against a control.
  • Culture analysis to detect microbial contamination.

Main Results:

  • No statistically significant difference in positive culture rates between tested nasal spray bottle types.
  • Isolation of methicillin-resistant coagulase-negative staphylococci in 4 out of 198 cultures.
  • Detection of potentially pathogenic bacteria indicates a risk of transmission.

Conclusions:

  • Standard prophylactic measures were insufficient to prevent microbial contamination.
  • Additional precautions are necessary to avoid interpatient cross-contamination.
  • Recommendations include autoclaving, disposable tips, or disposable devices.

Transmission-based Precautions II: Airborne and Protective Environment

Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...
Suctioning the Nasopharyngeal Airway01:29

Suctioning the Nasopharyngeal Airway

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.

Transmission-based Precautions I: Contact, Enteric, and Droplets

Transmission-based precautions are for patients known to be infected or suspected to be infected or colonized with organisms that pose a significant risk to others. Some transmission-based precautions include contact, enteric, and droplet.
Contact Precautions:
Contact precautions are the measures taken to prevent the transmission of infectious agents, especially epidemiologically important microorganisms such as MRSA or influenza, primarily transmitted through direct or indirect contact with an...
Standard Precaution01:26

Standard Precaution

Standard precautions are the minimum infection control safeguards used while caring for all patients, irrespective of their disease condition. They help prevent the spread of common infectious microorganisms to healthcare workers, patients, and visitors in all healthcare settings.
Hand hygiene is the most crucial means to prevent the transmission of disease. Employers are legally required to provide their workers with personal protective equipment (PPE) to minimize exposure or contact with...
Epistaxis01:30

Epistaxis

Epistaxis, or nosebleeds, occurs when small, swollen blood vessels in the nasal mucous membrane rupture. Typically, the anterior septum is the primary site of occurrence.
Etiology
Possible causes of this condition include high blood pressure, trauma, low humidity, upper respiratory tract infections, allergies, foreign bodies, nasal inhalation of corticosteroids or illicit drugs, excessive use of decongestant nasal sprays, facial or nasal surgery, anatomic malformation, tumors, or systemic...
Suctioning the Oropharyngeal Airway01:25

Suctioning the Oropharyngeal Airway

In preparing for oropharyngeal airway suctioning, a nurse must gather all necessary equipment, including a suction unit with tubing, a prepackaged suction kit, sterile gloves, water or saline for irrigation, a water-soluble lubricant, and additional personal protective equipment (such as a gown, mask, and goggles) to control infections.
After assembling the equipment, the nurse should practice hand hygiene and don appropriate PPE according to infection control guidelines to avoid the...
