A comparative study of the dose-response and time course of recovery of atra curium and rocuronium

Objective To compare the characteristics of the dose-response relationship and the time course of action between atracurium and rocuronium in adult patients anestheti zed with N(2)O-0(2)-fentanyl-thiopene. Methods Sixty patients, ASA grade Ⅰ, aged 18-50 years, scheduled for elective plastic s urgery were studied.All patients were randomly divided into either the atra c urium or rocuronium group.General anesthesia was maintained with 60% nitrous o xide and 40% oxygen, thiopentone, and fentanyl. Neuromuscular function was ass essed using an accelograph with train-of-four (TOF) stimulation at the wrist e very 12 seconds.The percentage depression of the first twitch (T(1)) was used as th e study parameter.The dose-response relationship of atracurium and rocuronium was determined by the cumulative dose-response technique.Results According to the dose-response curves established by a least squares linear reg ression, the potency ratio of atracurium to rocuronium was 1∶1.2. There were si gnificant differences in the ED(50), ED(90), and ED(95) between the two drugs. After the intravenous administration of equipotent doses of both dr ugs (1.5×ED(95)), the duration of peak effect, clinical duration, and total duration were significantly different between the two drugs, but their rec overy indexes were similar.Conclusions Atracurium and rocuronium are low-potency nondepolarizing relaxants with in termediate duration. As compared to atracurium, the neuromuscular blocking eff ect of rocuronium was about 20% less potent and its duration of action was shorter.     

Low risk-factor profile and long-term cardiovascular and noncardiovascular mortality and life expectancy: findings for 5 large cohorts of young adult and middle-aged men and women

CONTEXT: Three major coronary risk factors-serum cholesterol level, blood pressure, and smoking-increase incidence of coronary heart disease (CHD) and related end points. In previous investigations, risks for low-risk reference groups were estimated statistically because samples contained too few such people to measure risk. OBJECTIVE: To measure long-term mortality rates for individuals with favorable levels for all 3 major risk factors, compared with others. DESIGN: Two prospective studies, involving 5 cohorts based on age and sex, that enrolled persons with a range of risk factors. Low risk was defined as serum cholesterol level less than 5.17 mmol/L (<200 mg/dL), blood pressure less than orequal to 120/80 mm Hg, and no current cigarette smoking. All persons with a history of diabetes, myocardial infarction (MI), or, in 3 of 5 cohorts, electrocardiogram (ECG) abnormalities, were excluded. SETTING AND PARTICIPANTS: In 18 US cities, a total of 72144 men aged 35 through 39 years and 270671 men aged 40 through 57 years screened (1973-1975) for the Multiple Risk Factor Intervention Trial (MRFIT); in Chicago, a total of 10025 men aged 18 through 39 years, 7490 men aged 40 through 59 years, and 6229 women aged 40 through 59 years screened (1967-1973) for the Chicago Heart Association Detection Project in Industry (CHA) (N = 366559). MAIN OUTCOME MEASURES: Cause-specific mortality during 16 (MRFIT) and 22 (CHA) years, relative risks (RRs) of death, and estimated greater life expectancy, comparing low-risk subcohorts vs others by age strata. RESULTS: Low-risk persons comprised only 4.8% to 9.9% of the cohorts. All 5 low-risk groups experienced significantly and markedly lower CHD and cardiovascular disease death rates than those who had elevated cholesterol level, or blood pressure, or smoked. For example, age-adjusted RRs of CHD mortality ranged from 0.08 for CHA men aged 18 to 39 years to 0.23 for CHA men aged 40 through 59 years. The age-adjusted relative risks (RRs) for all cardiovascular disease mortality ranged from 0.15 for MRFIT men aged 35 through 39 years to 0.28 for CHA men aged 40 through 59 years. The age-adjusted RR for all-cause mortality rate ranged from 0.42 for CHA men aged 40 through 59 years to 0.60 for CHA women aged 40 through 59 years. Estimated greater life expectancy for low-risk groups ranged from 5.8 years for CHA women aged 40 through 59 years to 9.5 years for CHA men aged 18 through 39 years. CONCLUSIONS: Based on these very large cohort studies, for individuals with favorable levels of cholesterol and blood pressure who do not smoke and do not have diabetes, MI, or ECG abnormalities, long-term mortality is much lower and longevity is much greater. A substantial increase in the proportion of the population at lifetime low risk could contribute decisively to ending the CHD epidemic.     

增大顺阿曲库铵剂量与罗库溴铵麻醉诱导效果的比较

目的通过观察不同剂量顺阿曲库铵的起效时间、临床有效时间的变化,并与罗库溴铵比较,为临床手术患者个体化选择肌松药物及剂量提供理论依据。方法ASAI～Ⅱ级择期妇科手术女性患者120例,随机分为4组,每组30例,分别予顺阿曲库铵0．1mg／kg（A组）、0．15mg／kg（B组）、O．2mg／kg（c组）和罗库溴铵0．9mg／kg（D组）,咪达唑仑、芬太尼、异丙酚诱导麻醉,观察心率、血压和全身皮肤情况以及TOF的变化,并进行气管插管条件评级。结果各组肌松药起效时间分别是（226±57）s、（184±56）s、（135±45）s、（80-．I-25）S,C组分别与A、B、D相比较均有统计学意义（P〈0．05）;各组临床有效时间分别是（334±5）min、（41±8）min、（534±8）min、（42±11）min,C组分别与A、B、D相比较差异均有统计学意义（P〈0．05）。c组临床有效时间的离差与D组相比较差异有统计学意义（P〈0．05）。结论增大剂量法明显缩短顺阿曲库铵的插管起效时间,但与罗库溴铵相比,临床作用时间延长,便不适于短小外科手术的麻醉,而罗库溴铵临床作用时间的变异性较大,顺阿曲库铵的可控性优于罗库溴铵。

Calcaneal ultrasound parameters in men and women from central Croatia.

BACKGROUND: The aim of this study was to compare quantitative ultrasound parameters between women and men of various ages in a population from central Croatia and also to estimate the prevalence of osteoporosis in women. MATERIAL/METHODS: A total of 1006 participants were recruited for this study (550 men, 456 women), aged 20 to 89 years. Calcaneal quantitative ultrasound measurements were performed using a Sahara device (Hologic). Data were analyzed using the t-test and analysis of variance (ANOVA) with Tukey's post hoc test. RESULTS: Comparison of the ultrasound measures of the men exhibited significant differences across the age groups with the exception of broadband ultrasound attenuation (BUA). In the women, significant differences were found for BUA, speed of sound (SOS), and the quantitative ultrasound index (QUI). Gender comparison revealed significant differences between ultrasound parameters in the last three decade groups. Using a T-score threshold of -1.8, the prevalence of osteoporosis in women aged over 50 was 30.7% based on the quantitative ultrasound index. CONCLUSIONS: This study is the first report of quantitative ultrasound parameters in Croatian women. The results revealed lower QUI, BUA, and SOS in postmenopausal women than in men of the same age. The prevalence of osteoporosis in women over 50 years of age based on the quantitative ultrasound index was considerably higher than the previously reported prevalence of osteoporosis in men.
