目的探讨改良鼻饲法对老年危重症患者胃肠内营养并发症的影响。方法采用传统鼻饲法(对照组)与改良鼻饲法(试验组)进行老年危重症患者胃肠内营养支持,对并发症比较。试验组采用能全力营养素接输血管持续滴注方法鼻饲,对照组采用传统方法鼻饲(营养液同试验组),比较两组鼻饲后胃肠道并发症(呕吐和返流、误吸、腹胀、腹泻、消化道出血、便秘)发生率。结果鼻饲后胃肠道并发症发生率试验组明显低于对照组(P〈0.05)。结论能全力营养素液持续滴注鼻饲法可安全用于老年危重症患者,且对维持胃肠道结构和功能、减少并发症、促进营养状态和改善预后有显著临床意义,能明显提高护理工作效率。 相似文献

关于工业反哺农业的政策选择问题 总被引:4,自引:0,他引:4
张贡生 《辽东学院学报(社会科学版)》2006,8(4):106-109
如果我们将工业反哺农业理解为工业对于农业的一种价值让渡,那么,就工业的范围而言,不仅包括城市工业和第三产业,而且包括建立在农村的二、三产业。从内容上讲,主要包括工业产品、税收、价格、工业化制度、工业化理念、资金和保险支持等。 相似文献

考古发现证明 :我国是最早进入农业文明的国家。早在一万年以前 ,我国先民就已从事原始农业活动。而我国的水稻历史 ,至少比世界各国早五、六千年。我国同时是世界人工栽培粟最早的国家。早在 80 0 0年前的黄河流域 ,粟就已成为了先民的主要食粮。我国不仅是世界上最早的桑蚕和丝绸之国 ,而且远在五、六千年以前的帝喾和尧舜时代 ,我国先民就已熟练地掌握了养蚕缫丝和丝绸纺织技术 ,而且已达到了绝妙的工艺水平 相似文献

Background
Some studies have suggested an association between synthetic oxytocin administration and type of birth with the initiation and consolidation of breastfeeding.Aim
This study aimed to test whether oxytocin administration and type of birth are associated with cessation of exclusive breastfeeding at different periods. A second objective was to investigate whether the administered oxytocin dose is associated with cessation of exclusive breastfeeding.Methods
We conducted a prospective cohort study (n = 529) in a tertiary hospital. Only full-term singleton pregnancies were included. Four groups were established based on the type of birth (vaginal or cesarean) and the intrapartum administration of oxytocin. Follow-up was performed to evaluate the consolidation of exclusive breastfeeding at 1, 3 and 6 months.Findings
During follow-up, the proportion of exclusive breastfeeding decreased in all groups. After adjusting for confounding variables, the group with cesarean birth without oxytocin (planned cesarean birth) had the highest risk of cessation of exclusive breastfeeding (odds ratio [95% confidence interval], 2.51 [1.53–4.12]). No association was found between the oxytocin dose administered during birth and puerperium period and the cessation of exclusive breastfeeding.Conclusion
Planned cesarean birth without oxytocin is associated with the cessation of exclusive breastfeeding at 1, 3 and 6 months of life. It would be desirable to limit elective cesarean births to essentials as well as to give maximum support to encourage breastfeeding in this group of women. The dose of oxytocin given during birth and puerperium period is not associated with cessation of exclusive breastfeeding. 相似文献57.

Background
Increasing breastfeeding rates is one way of improving the short and long term health of Aboriginal and Torres Strait Islander children (hereafter referred to as Aboriginal). Despite the benefits of breastfeeding and recommendations for strategies to increase breastfeeding among Aboriginal people, there is a lack of available population data.Aim
To use population-based data from Victoria, Australia to compare breastfeeding initiation for Aboriginal and non-Aboriginal women and to explore factors associated with breastfeeding initiation of Aboriginal women.Methods
Routinely collected infant feeding data obtained from the Victorian Perinatal Data Collection (VPDC) was used. The VPDC is a mandatory, population-based system where maternal and infant data on all Victorian births are collected.Findings
Compared with non-Aboriginal women, Aboriginal women were less likely to attempt to breastfeed their baby (87.2% vs 95.3%; p < 0.001); more likely to give formula in hospital (39.6% vs 30.6%; p < 0.001) and less likely to give the last feed prior to discharge exclusively from the breast (64.4% vs 75.0% p < 0.001). For Aboriginal women, factors associated with not initiating breastfeeding were being single, multiparous, smoking and length of stay. Infant factors were gestation less than 37 weeks and low birthweight (<2,500 g).Conclusion
In Victoria, breastfeeding initiation is lower for Aboriginal women compared with non-Aboriginal women. Further research is needed to explore the effectiveness of interventions that may increase breastfeeding for Aboriginal women. 相似文献58.
