有创动脉压测定在冠状动脉介入治疗中的影响因素及处理 总被引:1,自引:0,他引:1
随着医疗技术的发展,冠状动脉介入治疗技术已被广泛应用于临床。但冠状动脉造影及介入治疗是一种具有潜在严重并发危险的有创手术过程,严密监测心电图及血压的变化是手术成功的重要保证之一。有创动脉压为直接感知血液内的压强,是血压测量的“金标准”,在冠状动脉介入治疗中,不仅客观地反映病人的血压变化,还直接反映导管尖端所处位置的压力,能够及时准确地反映主动脉及冠状动脉的压力变化,对指导手术进展、降低并发症有着重要意义。有创动脉压的波形及数值易受多种因素影响。本文分析了184例在冠状动脉介入治疗术中实施有创动脉压监测病人的资料,旨在探讨引起压力变化的相关因素,提高医护人员的应急处理能力和手术成功率。现报道如下。 相似文献

血压是反映人体循环系统机能的重要指标之一。有创动脉血压监测是一种经周围动脉(如桡动脉、足背动脉、股动脉)插入导管,将周围动脉内的压力通过压力传感器与监护仪连接,准确的反映每一个心动周期血压变化情况,直接显示收缩压、舒张压和平均动脉压的方法。弥补了袖带测压的不连续性,确保血压准确,可及时调整药物剂量, 相似文献

目的总结急性心肌梗死急诊介入治疗术中血压监测的意义。方法回顾性分析61例心肌梗死患者急诊介入术中有创血压及心电监测等情况。结果动脉血压与心肌梗死部位、冠状动脉病变程度、心律失常、迷走反射、无再流现象、手术操作、药物应用均有关联。术中发生一过性低血压40例次,心源性休克5例次。结论急诊介入治疗虽有一定风险,但术中密切监测血压等指标的变化,及时报告术者,医护整体配合,积极处理,能保证手术安全进行。 相似文献

桡动脉置管血压监测的护理 总被引:3,自引:0,他引:3
桡动脉置管血压监测是近年来开展的有创监测技术。在重症护理和麻醉中发挥重要的作用。通过直接反映动脉压力的动态变化和波形分析 ,有效地判断心血管功能。尤其是低心排出量时 ,有创血压弥补了无创血压非敏感性和非连续性的弱点。无效率由无创血压 12 .9%下降至 3.2 % [1] 。同时 ,动脉导管还是采集动脉血标本的理想途径[2 ] 。因此 ,正确应用和护理动脉导管是至关重要的。我院 1998年 12月~ 1999年 9月开展了 8例桡动脉置管血压监测。未发生 1例并发症。现报告如下。1 临床资料1.1 一般资料 本组共 8例 ,男性 5例 ,女性 3例 ,年龄 7~… 相似文献

OBJECTIVE: Although nausea and vomiting of pregnancy is the most common medical condition during pregnancy, there are many unanswered questions regarding its cause, epidemiologic features and optimal management. The objectives of this study were to ascertain the prevalence of nausea and vomiting in a sample of Canadian women, to characterize the distribution of their severity and to investigate the role of vitamin B6 deficiency in their etiology. DESIGN: Prospective study. SETTING: Antenatal counselling service for pregnant women. PATIENTS: Three cohorts of women: a prospective, population-based cohort of 193 women, to estimate the rate and severity of nausea and vomiting (cohort A); a cohort of 555 women who sought advice for nausea with or without vomiting, to study the correlation between the maximal daily number of episodes of vomiting and maximal weight loss (cohort B); and a prospective cohort of 301 women who reported vomiting, to correlate vitamin supplementation with vomiting (cohort C). INTERVENTIONS: All 3 cohorts were interviewed during the counselling session, and cohort B was followed up prospectively. OUTCOME MEASURES: Frequency of nausea and vomiting, weight loss, maximal number of daily episodes of vomiting, rate of multivitamin supplementation. RESULTS: Overall, 67% of the women in cohort A reported experiencing nausea or vomiting, or both; 22% reported vomiting, and 9% experienced weight loss. In cohort B there was a significant correlation between the maximal number of daily episodes of vomiting and maximal weight loss, although there was wide variation (r2 = 0.25, p < 0.001). There was a highly significant correlation between the number of daily vomiting episodes and mean weight loss (r2 = 0.99). In cohort C, vomiting was significantly associated with lack of supplementation with multivitamins before 6 weeks' gestation (p = 0.002). CONCLUSIONS: The relation between number of daily vomiting episodes and mean weight loss may serve as a clinical tool to assess the severity of nausea and vomiting in pregnancy and the success of anti-emetics and rehydration regimens. Further study is needed to elucidate the biologic basis of the observed association between vomiting and lack of multivitamin supplementation in early pregnancy. 相似文献

心血管疾病是我国的多发病和人群的主要死亡原因之一,而高血压已成为中老年人的常见病,是冠心病、脑卒中最主要的危险因素,已成为世界性公共卫生问题。随着我国经济的发展及人们生活水平的日益提高,我国在1958年、1979年、1991年分别进行了全国性的高血压普查,结果表明,我国高血压患病率在持续上升,且上升速度逐年加快。由于文化程度、生活习惯以及信息来源不足的差异也是导致城居民高血压患病率持续上升的重要原因,因此指导城乡居民进行合理的饮食,对预防高血压的发生、发展有着重要的意义。 相似文献

Harold S. Zamansky Roger F. Brightbill 《The International journal of clinical and experimental hypnosis》2013,61(4):279-290
A form of the Semantic Differential, containing 9 concepts related to hypnosis and research, was administered to 96 hypnotically inexperienced male Ss. The Ss were later asked to volunteer for a hypnotic experiment, and the hypnotic susceptibility of all volunteers (N = 51) was then determined. Semantic Differential responses of volunteers and nonvolunteers and of highly susceptible and unhyp-notizable Ss were compared. Differences between groups, in both comparisons, were generally not statistically significant, a finding which suggests that there is no simple relationship between paper-and-pencil measures of attitudes and volunteering for hypnotic experiments or hypnotizability. 相似文献
