摘要:目的:探討改良De Vega環縮術與經典De Vega環縮術相比對于治療重度三尖瓣返流是否具有更好的成形效果。方法: 2007年12月至2009年3月對29例重度三尖瓣返流的患者行De Vega環縮術。其中16例行改良De Vega環縮術,13例行經典De Vega環縮術,隨訪比較兩組患者三尖瓣返流程度,右心室舒張期末內徑,EF值及心功能分級。以秩和檢驗分析研究兩組患者三尖瓣返流程度和心功能分級的差異,以t檢驗研究兩組患者右心室舒張末期內徑及EF值變化。結果:術前兩組患者一般指標無顯著差異。兩組患者隨訪時間無顯著差異。隨訪經典De Vega組重度返流1例,中度返流5例,輕度返流5例,微量及無返流2例;改良De Vega組無中、重度返流,輕度返流8例,微量及無返流8例。經分析顯示兩組患者三尖瓣返流程度結果差異有統計學意義(Plt;0.05)。經典De Vega組心功能分級I級5例,II級7例,III級1例;改良De Vega組I級7例,II級8例,III級1例,兩組患者心功能差異無統計學意義(Pgt;0.05)。兩組患者右室舒張期末內徑及EF值組內比較隨訪與術前差異均有統計學意義(Plt;0.05),隨訪時組間比較差異有統計學意義(Plt;0.05), 改良De Vega環縮術隨訪時右室舒張期末內徑縮小更顯著,射血分數改善更明顯。結論:改良De Vega環縮術治療重度三尖瓣返流效果優于經典De Vega環縮術。Abstract: Objective: To compare the efficacy of one kind of modified De Vega technique and traditional De Vega technique for the correction of severe tricuspid regurgitation. Methods: From December 2007 to March 2009, 29 patients were treated with tricuspid valve annuloplasty. These were 16 patients in modified De Vega annuloplasty group and the others (13 patients) in traditional De Vega annuloplasty group. The grade of tricuspid regurgitation、New York Heart Association (NYHA) functional class、ejection fraction (EF) and the right ventricular enddiastolic dimension of two groups were followed and reviewed. Results: There was no statistically difference between two groups about preoperative characteristics and followup time. There was 1 patient with severe TR, 5 patients with moderate TR, 5 patients with mild TR and 2 patients without TR in traditional De Vega annuloplasty group after the operations. In modified De Vega annuloplasty group, no patient was observed with severe or moderate TR, 8 patients with mild TR, and 8 patients without TR. At interval time, there was significant difference in the grade of tricuspid regurgitation between two groups (Plt;0. 05). Both tricuspid valve plasty techniques could reduce the right ventricular enddiastolic dimension and improve ejection fraction significantly (Plt; 0. 05), and there was significant difference in the right ventricular enddiastolic dimension and ejection fraction at interval time between two groups (Plt;0.05). Conclusions: The outcome of modified tricuspid De Vega technique is superior to that of traditional De Vega technique in correcting severe tricuspid regurgitation.
摘要:目的:探討纖支鏡經口引導氣管插管在慢阻肺合并重度呼吸衰竭救治中的臨床應用價值。方法:237例慢阻肺合并重度呼吸衰竭患者,隨機分為纖支鏡經口引導氣管插管組(纖支鏡組)125例和喉鏡經口引導氣管插管組(喉鏡組)112例,分別在纖支鏡和喉鏡引導下按常規進行氣管插管術。結果:纖支鏡組和喉鏡組一次獲得插管成功率分別為984%和920%(P<005),平均插管時間分別為(613±391) min 和(926±415) min(P<005)。纖支鏡組有5例患者出現咽喉部少量出血,并發癥發生率為40%;喉鏡組共有12例發生并發癥,并發癥發生率為107%(P<005),其中齒、舌、咽或喉部損傷6例,反射性嘔吐致誤吸2例,單側肺通氣1例,插入食管2例,心跳呼吸驟停1例。結論:纖支鏡經口引導氣管插管在慢阻肺合并重度呼吸衰竭救治中是一種簡便快速、成功率高和并發癥少的有效方法,值得臨床推廣應用。Abstract: Objective: To evaluate the efficacy of endotracheal intubation under fiberoptic bronchoscope through mouth in severe respiratory failure. Methods:Two hundreds and thirtyseven cases of severe respiratory failure were divided into two groups at random (fiberoptic bronchoscope group and laryngoscope group), 125 cases were intubated through mouth under fiberoptic bronchoscope, the others were intubated through mouth by laryngoscope. Results: The successful rates of endotracheal intubation were 98.4% and 92.0% in two groups respectively (P <005), the mean intubation timewere (613±391) min and (926±415) min respectively ( P < 005), 4 cases in fiberoptic bronchoscope group appeared a little blood in throat, the complication rate was 32% 12 cases in the laryngoscope group had complications, the complication rate was 107%( P< 005). Among it, 6 cases had the injury of tooth, tongue, gullet and larynx.The cases of reflexvomiting were 2,pulmonary ventilation by single lung were 1, intubation in esophagus were 2, cardiopulmonary arrest were 1.Conclusions:Endotracheal intubation under fiberoptic bronchoscope through mouth was accurate, the fewer complications and effective for patients, and could be used widely in clinical applications.
