中文摘要 | 為了要瞭解高壓氧體與超音波霧化器在治療氧喘之臨床功能而進行本研究。使用高壓氧體霧化器時所需的最小流量為6 L/min,殘餘液體量為0.8 cc。使用超音波霧化器的殘餘量為8.5cc。Terbutaline及fenoterol單一劑量溶液之滲透壓為等張性溶液。使用高壓氧體霧化器時,滲透壓會逐漸上升,而超音波霧化器只有些微的上升。純terbutaline及fenoterol單一劑量溶液偏酸。在使用高壓氧體霧化器時,容器杯內及吸入藥物管口處之溫度在12分鍾後下降近8度,而超音波氧體霧化器反而有小幅度的的上升。總之,這兩種氣體霧化器各有各的特性,使用高壓氧體霧化器時要注意流量至少要高於6 L/min, 使用超音波氣體露化器時由於殘餘量多,溶液至少應稀釋至20ml。純terbutaline及fenoterol單一劑量溶液偏酸,最好先以生理食鹽水稀釋後再使用。在使用超音波氣體霧化器時,由於比較不會冷卻氣管及提高滲透壓,應該是一個比較好的選擇。 |
英文摘要 | In order to study the detailed function of two kinds of nebulizers commonly used in clinical asthma treatment, compressed-air and ultrasonic, this study was conducted. At the beginning, various flow rates were adjusted, paired with different volumes of solutions in the container. The changes of temperature, pH, and osmolality during the course of nebulization were examined. Normal saline, terbutaline, and fenoterol solutions were used as the nebulized solutions. The study was performed in an environment in ambient temperature around 20°C and relative humidity around 70%. The results showed a minimal 6 L/min flow rate was required to nebulize the solution when using the compressed- air nebulizer. The dead volume was about 0.8 ml for compressed-air and 8.5 ml for the ultrasonic nebulizer. When using the compressed-air nebulizer, the temperature, both in the solution and at the mouthpiece site, dropped gradually. On the contrary, the temperatures at both sites increased a little bit when using the ultrasonic nebulizer. The pH values of pure terbutaline and fenoterol nebulized solutions were acidic (3.58 and 3.00 respectively). The osmolality of terbutaline and fenoterol nebulized solutions were isotonic. The osmolality increased gradually during the course of nebulization, to a greater extent in the compressed-air nebulizer. In conclusion, both types of nebulizers have their special features. The ultrasonic nebulizer displays less extent in change of temperature and osmolality during nebulization and is expected to be a better device in treating asthmatic patients in terms of lesser effect on cooling and changing the osmolality of airway mucosa. |
