Insights

Children with chronic lung disease exposed to hypoxia show cochlear dysfunction. Otoacoustic emissions testing revealed hearing sensitivity issues, but inhaled aminoglycosides were found to be safe for auditory functions.

Area of Science:

  • Pediatric Otolaryngology
  • Pulmonology
  • Audiology

Background:

  • Chronic hypoxia significantly impacts cochlear function and hearing sensitivity.
  • Otoacoustic emissions (OAEs) are effective for detecting subclinical cochlear impairment.
  • Ototoxic drugs, such as aminoglycosides, are frequently used in managing chronic lung diseases.

Purpose of the Study:

  • To evaluate cochlear function in children with chronic lung diseases.
  • To assess the effects of prolonged hypoxia and inhaled aminoglycosides on auditory health.
  • To utilize transient evoked otoacoustic emissions (TEOAEs) and basic audiological tests.

Main Methods:

  • A cross-sectional study involving 30 Egyptian children with chronic lung disease.
  • A control group of 20 healthy children was included.
  • Audiological evaluation and TEOAEs were performed.

Main Results:

  • Twenty percent (6/30) of children with chronic lung disease exhibited abnormal TEOAE findings.
  • Prolonged hypoxia demonstrated a statistically significant impact on OAEs (P<0.05).
  • No significant adverse effects of inhaled aminoglycosides were observed on pure tone audiometry, speech audiometry, or TEOAEs.

Conclusions:

  • Children suffering from chronic lung diseases are at risk of cochlear dysfunction due to prolonged hypoxia.
  • Inhaled aminoglycosides appear to be relatively safe concerning auditory functions in this patient group.

Assessment of Respiration01:23

Assessment of Respiration

The respiratory system's basic structures and primary functions lay the foundation for nurses' comprehensive respiratory assessments. This assessment includes subjective and objective data to gauge the patient's respiratory health.
Subjective Assessment: Nurses interview the patient to gather information directly during the subjective assessment. It includes questions about the individual's medical history, medications, and symptoms, focusing on past respiratory conditions like asthma or COPD,...

Physical Assessment of the Respiratory Tract IV: Auscultation

Auscultation is a crucial component of the physical assessment of the respiratory tract. It offers valuable insights into airflow through the bronchial tree and potential lung obstructions. This process involves careful listening to breath, voice, and adventitious sounds, which can reveal a wealth of information about a patient's respiratory health.
Breath Sounds
Breath sounds are categorized into vesicular, bronchovesicular, and bronchial.

Respiratory System Abnormal Finding I: Inspection and Percussion

Respiratory system abnormalities are a significant concern in healthcare due to their potential to indicate underlying severe conditions like Chronic Obstructive Pulmonary Disease (COPD), asthma, and pneumonia. These abnormalities can often be detected through physical examination methods like inspection and percussion.
Inspection Findings
During an inspection, several findings may suggest the presence of respiratory distress or disease. Pursed-lip breathing, where exhalation is slowed by...
