Complete recovery after near-fatal venous air embolism during cesarean section.
ABSTRACT During replacement to the abdomen of the exteriorized uterus at cesarean section under epidural block, a previously healthy woman developed cardiorespiratory arrest. Tracheal intubation revealed low end-tidal carbon dioxide concentration suggesting embolization. Resuscitative efforts were successful. Uterine exteriorization - as well as the Trendelenburg position - significantly increase the risk of air embolization so that routine use of appropriate monitors is indicated to facilitate early diagnosis.
Conference Paper: Low-k materials etch and strip optimization for sub 0.25 μm technology[Show abstract] [Hide abstract]
ABSTRACT: With the introduction of low-k materials into the intermetal dielectric (IMD) layers, it is important to optimize the via etch process in order to minimize the IMD degradation that is caused by harsh O<sub>2</sub> and wet stripping treatments. A simple, sensitive, and cost-effective measurement method is introduced for the determination of low-k material degradation caused during the via etch process. By using a single damascene comb structure, a large sidewall area of low-k material can be exposed to the etch strip process in question. The intra-line capacitance between the trenches is an extremely sensitive parameter to evaluate material degradation. Using this method, etch and strip processes can be tailored for a specific low-k material, which in turn, improve the interconnect performance and via yield. The results from this method are identical to results coming from the optimization of electrical performance with completely integrated chips and is in very good agreement with FTIR analysis for bare filmsInterconnect Technology, 1999.

ABSTRACT: The Healthy People 2000 report set the objective of increasing the percentage of women 40 or older who had ever received a mammogram and clinical breast examination to 80% by the year 2000. The report used a baseline of 36% for all American women and 20% for Hispanic women. The purpose of this study was to compare baseline estimates with data obtained in five Hispanic communities. Common survey measures were administered in five studies participating in a National Cancer Institute Cooperative agreement. The surveys evaluated history of mammography in five Hispanic communities in the southwestern Unites States. Across the five communities, the rates of mammography use were significantly higher than the national baseline. Among women 40-49 years of age, 55% had completed mammography (95% confidence interval [CI] = 52%, 57%). Among women 50 years of age or older, 64% had received a mammogram (95% CI = 62%, 66%). Older women (above age 50) were significantly more likely to have completed the test than younger women (younger than age 50), and mammography was obtained less often among women who were uninsured and those who had lower levels of acculturation. We conclude that the rate of mammography use among Hispanic women has increased significantly over the last few years and that we are on track to reach the goal of 80% mammography compliance for Hispanic women 40 years and older by the year 2000.American Journal of Preventive Medicine 01/1996; 12(6):467-71. · 3.95 Impact Factor
