Suctioning the Nasopharyngeal Airway

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.

Area of Science:

Environmental Science
Materials Science
Medical Devices

Background:

Sinusitis and rhinitis are common conditions often treated with nasal irrigation.
Microplastic contamination is a growing global concern across various environments.
The potential health impacts of microplastics necessitate investigation in medical applications.

Purpose of the Study:

To quantify microplastics in nasal irrigation products.
To assess human exposure to microplastics via these methods.
To compare microplastic levels across different nasal irrigation product types.

Main Methods:

Analyzed 150 samples: nasal wash bottles, seawater sprays, and syringes.
Filtered samples and identified microplastics using microscopy and chemical staining.
Calculated microplastic load per product and per milliliter for exposure assessment.

Main Results:

Detected an average of 6.49 microplastics/product across all samples.
Nasal wash bottles exhibited the highest microplastic levels (up to 92/product).
Significant differences in microplastic exposure were found between product types.

Conclusions:

Nasal irrigation treatments can increase microplastic exposure.
Microplastics may cause inflammation and oxidative stress.
Stricter regulations and production oversight are needed to minimize microplastic exposure.
