背景　鼻中膈彎曲病人常受鼻部症狀干擾，對睡眠品質的影響尚未有研究證實，是值得探討的議題。目的　探討鼻中膈彎曲病人睡眠品質、症狀干擾情形及嗜睡程度，並瞭解此三者間的關聯性，與找出影響鼻中膈彎曲病人睡眠品質的相關因素。方法　採橫斷式研究設計，以鼻中膈彎曲病人為對象，使用匹茲堡睡眠品質量表測量睡眠品質、嗜睡量表測量嗜睡程度及症狀干擾量表測量症狀干擾程度。結果　本研究共收集146位鼻中膈彎曲病人，男性居多(69.2%)，平均年齡為34.1±10.8。睡眠品質平均得分為7.84±3.67（範圍為0-21），屬於睡眠品質不佳，嗜睡程度平均得分為9.16±4.67（範圍為0-24）。女性睡眠品質較男性差，有小睡習慣者之睡眠品質優於無小睡者。症狀干擾程度愈高，其睡眠品質愈差，嗜睡程度愈嚴重。症狀干擾程度、性別及小睡為預測睡眠品質之有意義變項，共可解釋13.3%的總變異量。結論／實務應用　本研究顯示鼻中膈彎曲病人睡眠品質普遍不佳。建議若欲改善此類病人之睡眠品質，可由減低病人鼻部症狀干擾程度與嗜睡情形著手，此結果亦可作為護理人員臨床衛教之參考。

Background: The anatomical structure of the nose is the primary cause of nasal septum deviation (NSD). The impact of NSD symptoms on sleep status is an issue that has been little explored and thus deserves consideration and investigation.Purpose: This study explored sleep quality, nasal interference symptoms and sleep in NSD patients. This study also tried to identify correlations among these three variables and the primary factors that influence NSD patient sleep quality.Methods: The study used a cross-sectional design and obtained data through interviews with NSD patients. Sleep quality was measured using the Pittsburgh Sleep Quality Index (PSQI); sleepiness was measured using the Epworth Sleep Sleepiness (ESS) scale, and symptom interference was measured using a symptom interference scale.Results: A total of 146 NSD patients were recruited for this study. Most (69.2%) were male and mean age was 34.1±10.8 years. Results revealed the following: (1) Subjects had poor sleep quality, with an average PSQI score of 7.84±3.67 (range: 0 to 21); (2) Mean ESS was 9.16±4.67 (range: 0 to 24); (3) One-third (34.2%) of the subjects experienced insomnia, with female patients reporting worse sleep quality males; (4) Subjects who napped had better sleep quality than those who did not; (5) Higher symptom interference correlated with poorer sleep quality and greater sleepiness. Symptoms interference, gender, and napping were factors found to significantly influence sleep quality, predicting 13.3% of sleep quality variance.Conclusions/Implications for practice: In conclusion, the study found subjects experienced poor sleep quality. This result suggests reducing nasal interference symptoms and sleeping more as a way to improve NSD patient sleep quality. Nurses may apply these conclusions in clinical NSD patient education.
