Abstract
BackgroundNasal obstruction is a significant medical problem. This study aimed to examine the effect of nasal obstruction and nasal packing on arterial blood gases and pulmonary function indices, and the impact of the elimination of nasal obstruction on preoperative values.ResultsThe mean age of the study population was 26.6 ± 10.1 years, males represented 50.8%. Spirometric indices showed statistically significant improvement (preoperative forced expiratory volume in 1st second 66.9 ± 13.9 vs 79.6 ± 14.9 postoperative and preoperative forced vital capacity 65.5 ± 12.7 vs 80.4 ± 13.8 postoperative). Oxygen saturation was significantly lower during nasal packing (95.6 ± 1.6 preoperative vs 94.7 ± 2.8 with nasal pack), and significant improvement (97.2 ± 1.4) was observed after removal of the nasal pack. Nasal obstruction scores significantly improved.ConclusionThe results of this study indicate that either simple nasal obstruction or nasal packing may cause hypoxemia and abnormalities in lung function tests. Hypoxemia was more evident with nasal packing.
Highlights
Nasal obstruction is a significant medical problem
The nasal airway accounts for ≥ 50% of total airway resistance, with most of this contribution arising from the anterior part of the nose [4], this resistance is increased in pathologic conditions [5]
Hypoxemia was observed in some cases pre-operatively, and there was a significant decrease in partial pressure of oxygen (PaO2), pH, and oxygen saturation (SPO2%) with nasal packing
Summary
Nasal obstruction is a significant medical problem. This study aimed to examine the effect of nasal obstruction and nasal packing on arterial blood gases and pulmonary function indices, and the impact of the elimination of nasal obstruction on preoperative values. Nasal airway obstruction and nasal congestion are significant presentations in otorhinolaryngology practice. They carry significant discomfort, economic impact, and negative effect on the quality of life [1, 2]. Nasal resistance is different from side to side and because of nasal mucosal changes in nasal turbinate in a cycle pattern (nasal cycle) [6]. This cycle occurs in about 80% of the adult population and this cycle plays a role in respiratory defense [7]. Changes in respiratory mechanics and arterial blood gases may occur
