本研究旨在建立腸脹氣之相關因素及定義性特徵並進行臨床測定。分兩階段進行，階段一以護理人員為對象，藉由專家效度、診斷內容效度及因素分析共確立出16項腸脹氣相關因素及13項腸脹氣定義性特徵。階段二以北部兩家地區醫院之腸胃科（32位）及非腸胃科（22位）主訴有腸脹氣達12小時以上之病患為研究對象，結果顯示二族群在相關因素上，腸胃科病患最常見三項依序為麻痺性腸阻塞、長期臥床及便秘；而在非腸胃科病患最常見三項依序為長期臥床、便秘及腹部手術。在定義性特徵上，腸胃科病患最常見三項依序為腸鼓音、腹部鼓脹及腹部疼痛；而非腸胃科病患最常見三項依序為腸鼓音、腹部鼓脹及腹部不適。

The purpose of this study is to establish and validate the related factors and defining characteristics of flatulence. We established 16 related factors and 13 defining characteristics of flatulence, using expert content validity, diagnostic content validity and factor analysis, Clinical validation was performed on patients from the gastrointestinal section (n=32) and non-gastrointestinal sections (n=22) of two regional hospitals in the north of Taiwan. Cases were enrolled if flatulence lasted for 12 hours or longer. The most common related factors of flatulence are paralytic ileus, bedridden state, and constipation in cases from gastrointestinal section; and bedridden state, constipation, abdominal surgery in cases from Non-gastrointestinal section. The most common defining characteristics of flatulence are tympanic percussion, bloating, and abdominal pain in cases from gastrointestinal sections and tympanic percussion, bloating, abdominal discomfort in cases from non-gastrointestinal sections.
