RESUMO
Objective To explore the effects of two methods for deep endotracheal suction.Methods Forty patients who had ineffective airway clearance or lung infections or refused suction were randomly divided into observation group (n=21) and control group (n=19).Temporay airway was established by using oropharyngeal airway.Then,the control group received subglottic suction after pading the shoulder with ordinary pillow (≤10cm),while the observation group received subglottic suction after pading the shoulder with homemade pillow (=15cm).The two groups were compared in terms of sputum suction effect and mucosal injury.Results There was no incidence of mucosal injury in the observation group but three in the control group.The times of suctioning in the observation group were fewer than those of the control group and the volume for suctioning was larger as well (allP<0.05).Conclusion Deep endotracheal suction through oropharyngeal airway,shoulder elevation for 15cm,temporary indwelling of suction tubes can achieve better suction effect without corresponding complications.
RESUMO
Objective To establish the method for detemining the content of Icariin in Chuanlong Guci Pian by HPLC. Methods Diamonsil ODS1 C18 Column was used with acetonitrile-water (27∶73) as the mobile phase, detection wavelength as 270 nm, and flow rate was 1.0 mL/min. Results The calibration curve was linear at the range of 0.125～1.00 ?g for Icariin and linear equation was Y=81 601X+10 356, r 2=0.999 7. The average recovery was 99.12% and RSD was 0.65% (n=6). Conclusion This method was simple, accurate and proper, and the reduplication of the result was good, which provides scientific quantitative analysis of Icariin in Chuanlong Guci Pian.
RESUMO
Objective To establish the method for detemining the content of Paeonolum in Fufang Yuanhu Zhitong Pian by HPLC. Methods Hypersil BDS C_(18) column was used with methyl alcohol-ware (1 : 1) as the mobile phase, detection wavelength as 274 nm, and flow rate was 1.0 mL/min. Results The calibration curve was linear at the range of 0.103～0.824 ?g for aeonolum, and linear equation was Y= 5 043.774 9X+275.5915, r=0.9997. The average recovery was 98.59% and the related standard deviation (RSD) was 0.68% (n =6). Conclusion This method was simple, accurate and proper, which provide scientific quantitative analysis method of Paeonolum in Fufang Yuanhu Zhitong pian and the repeatability was good.
