Evaluation of audio-rhinological changes during pregnancy
Pregnancy causes significant audiological and nasal changes due to hormonal shifts. These physiological alterations, including hearing thresholds and nasal patency, typically resolve postpartum.
Area of Science:
- Otolaryngology
- Obstetrics & Gynecology
- Physiology
Background:
- Physiological changes during pregnancy significantly impact various bodily systems.
- Audiological and nasal alterations are notable during gestation, primarily driven by fluctuating sex hormones.
Purpose of the Study:
- To document and analyze audiological and nasal changes during pregnancy.
- To investigate the correlation between pregnancy and changes in hearing and nasal patency.
Main Methods:
- A study involving 40 pregnant and 40 non-pregnant women (ages 20-35) was conducted.
- Pure Tone Audiometry assessed hearing thresholds across trimesters and postpartum, while Gertner's plate method measured nasal patency.
Main Results:
- Significant differences in pure tone thresholds were observed at lower frequencies (125-1000 Hz, P < 0.001).
- Nasal patency showed highly significant changes across trimesters and compared to controls (P < 0.001).
- Changes were most pronounced in the first trimester, gradually improving and normalizing postpartum.
Conclusions:
- Pregnancy-induced audiological and nasal changes are significant and hormonally mediated.
- These temporary physiological changes typically resolve after delivery.
- The number of pregnancies did not correlate with the observed changes.

Upper Respiratory Drugs: Antitussives, Expectorants, and Mucolytics
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...

Palpation Findings
During a respiratory assessment, palpation can reveal several vital abnormalities:
Physical Assessment of the Respiratory Tract IV: Auscultation
Breath Sounds
Breath sounds are categorized into vesicular, bronchovesicular, and bronchial.
Assessment of Respiration
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,...
