ABSTRACT
Objective This paper aims to find a best position of ephedrine hydrochloride nasal drops by comparing earache occurred in hyperbaric oxygen(HBO )therapy while using ephedrine hydrochloride nasal drops in two positions: laying in lateral position of 45°with head leaning back; laying down flat, so as to supply reference for prevention of earache. Methods We selected 300 cases of HBO patients who were firstly treated by HBO and randomly divided into the observation group and the control group with 150 cases in each group. All these patients were treated by large medical hyperbaric oxygen tank. On the first to third day, ephedrine hydrochloride nasal drops were put into the patients before they were sent into the oxygen tank. Patients in the observation group lay in lateral position of 45°with their head leaning back, and those in the control group were in horizontal position. We put three drops of 1% of ephedrine hydrochloride nasal drops respectively into their nasal cavity. When they came out of the oxygen tank, we asked them if they felt earache and checked their tympanic membrane so as to make a comparison. Results It was found that earache, rate of tympanic membrane injury and the extent of such injury in the observation group was obviously less than that in the control group, there was difference in statistics between these two groups. Conclusions Before HBO treatment, ephedrine hydrochloride nasal drops that put in lateral position of 45°with patients head leaning back can reduce the possibilities of earache occurred in HBO. It was also observed that such position was an ideal one which had anatomical characteristics of Eustachian tube and was safer than laying down flat, so such position is more practical.
ABSTRACT
Objective To investigate the prevalence of metabolic syndrome(MS)and its components among people aged over 15 years in Guangxi Zhuang Autonomous Region and to compare the difference between Zhuang and Han populations.Methods Adopting cluster sampling,a survey of diabetes mellitus was conducted in Guangxi from 2003 to 2005.A total of 27 240 subjects aged over 15 years with complete data,including background information of each individual,blood pressure,lipid profile,plasma glucose,blood uric acid and fasting insulin were analyzed in this study.The prevalence of MS and its components were analysed in Han and Zhuang Chinese in Guangxi.The criteria of International Diabetes Federation(IDF)in 2005 and the China Diabetes Society(CDS)in 2004 were applied for diagnosis.Results(1)The crude prevalence rates of MS according to IDF definition were 13.15%in total,12.41%in male and 14.11%in female respectively.The age- standardized prevalence rates of MS(according to the population composition in China in 2000)were 7.66%in total,7.26%in male and 8.81%in female.The crude prevalence rates of MS according to CDS definition were 10.75%in total,13.45%in male and 7.28%in female respectively and the age-standar-dized prevalence rates of MS were 5.9%in total,7.21%in male and 4.31%in female.The prevalence of MS in total,male and female was increasing with age(P
