Upper Respiratory Drugs: Antitussives, Expectorants, and Mucolytics

Upper Respiratory Drugs: Antitussives, Expectorants, and Mucolytics

Respiratory symptoms, such as congestion and cough, commonly accompany respiratory tract conditions. Various medications, such as antitussives, expectorants, and mucolytics, play crucial roles in providing relief.
Antitussives include codeine, dextromethorphan (Robitussin), and benzonatate (Tessalon). Codeine and dextromethorphan exert their effects centrally by suppressing the cough reflex center in the medulla. Benzonatate operates peripherally within the respiratory tract by anesthetizing...

Nose and Nasal Cavity

Nose and Nasal Cavity

The nose is composed of an observable exterior segment (external nose) and an internal segment within the skull known as the nasal cavity (internal nose). The external nose, visible on the face, consists of a framework of bone and hyaline cartilage enveloped in skin and muscle and lined with a mucous membrane. This structure is supported by the frontal bone, nasal bones, and maxillary bone and is supplemented by a cartilaginous framework comprising the septal nasal cartilage, lateral nasal...

Physical Assessment of the Respiratory Tract I: Health History

Physical Assessment of the Respiratory Tract I: Health History

Physical assessment of the respiratory tract is critical to patient care. It allows healthcare professionals to identify and manage various respiratory conditions. The process involves a combination of subjective and objective data collection.
Subjective Data
Subjective data provides vital information about the patient's health history and symptoms. This data is typically collected through interviews in which patients describe their experiences, symptoms, and concerns.
Health history and key...

Epistaxis

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 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.

Chronic Obstructive Pulmonary Disease III: Chronic Bronchitis Features

Chronic Obstructive Pulmonary Disease III: Chronic Bronchitis Features

Chronic bronchitis is a key phenotype of chronic obstructive pulmonary disease (COPD), characterized by airway-centered inflammation and mucus overproduction. It develops from long-term exposure to harmful particles or gases, most commonly cigarette smoke, which triggers a persistent inflammatory response.Cellular and Structural ChangesInflammation initially affects the large bronchi and later the smaller airways, with infiltration by immune cells, including neutrophils, macrophages, and...

Summary

Nasal resistance in children aged 9-13 generally decreases but can temporarily increase, often before age 12. These findings are important for understanding nasal impairment in orthodontic patients.

Respiratory Physiology

Background:

Nasal resistance is a critical factor in respiratory function.
Longitudinal data on nasal resistance changes during childhood is limited.
Understanding these changes is crucial for identifying potential nasal impairments in children undergoing orthodontic treatment.

Purpose of the Study:

To longitudinally examine changes in nasal resistance in children from age 9 to 13.
To identify patterns and timing of nasal resistance fluctuations.
To investigate potential gender differences in nasal resistance development.

Main Methods:

Annual measurement of nasal resistance in 82 children.
Longitudinal study design tracking participants over four years.
Statistical analysis to assess age-related trends and individual variations.

Main Results:

Nasal resistance significantly decreased with age between 9 and 13 years.
A transient increase in nasal resistance was observed in most children.
This transient increase typically occurred before age 12, with individual timing variations.
No significant gender differences in nasal resistance changes were found.

Conclusions:

Nasal resistance follows a complex developmental trajectory in late childhood.
Prepubertal orthodontic patients may experience periodic, transient nasal impairments.
These findings highlight the need for careful monitoring of nasal function in pediatric orthodontic patients.
