目的 探讨纯氧和空气复苏对新生儿发育的影响,为新生儿复苏用氧选择提供依据.方法 对2005年1月-2007年1月在保定市妇幼保健院进行窒息复苏的30例患儿在24个月时进行随访,依据复苏用氧浓度分为纯氧复苏组(20例)和空气复苏组(10例),内容包括出生时胎龄、出生体重、身长、头围、阿氏评分(1 min,5 min)、心率(1 min,5 min)、随访时体重、身长、头围及运动发育标志(坐、爬、站、走时间).结果 出生时患儿身体数据差异无统计学意义,24个月随访,患儿身高、体重、头围及运动发育标志差异均无统计学意义(P>0.05).结论 空气复苏对新生儿窒息患者是安全有效的. 相似文献

反映手术间利用效率的统计指标与方法探讨 总被引:1,自引:0,他引:1
目的 探索反映手术室工作状态的指标和方法,为了解科室需求、合理利用手术室资源奠定基础。方法 提取医院局域网中有关手术安排、手术过程、麻醉等信息,通过常用统计指标、统计图表,反映手术室、手术科室、手术间的工作状态。结果 工作日手术问日均工作6.34小时,节假日日均工作0.6l小时。工作日13点后有近l/3的空台,14点后近l/2空台。个别手术间利用率偏低。结论 1.由在用手术间时点统计结果可见,14点后接台手术尚有一定潜力,节假日安排手术潜力更大;2.工作日间均工作时数已近满负荷,若要进一步提高手术间的利用,需加强麻醉科和手术室力量。 相似文献

评价酶联免疫检测血清CYFRA21—1对非小细胞肺癌的诊断价值 总被引:8,自引:0,他引:8
目的评价检测CYFRA21┐1对非小细胞肺癌的诊断价值。方法用ELISA法测定70例肺癌(LC)其中47例非小细胞肺癌(NSCLC),3例小细胞肺癌(SCLC)和20例未分型肺癌、64例肺部良性疾病患者及40例健康人血清CYFRA21┐1浓度。试验的诊断性能用相对操作特征(ROC)分析法估测之。结果测得全阈诊断准确率(OveralDiag┐nosticAccuracies)LC为0.75、NSCLC为0.76,SQC为0.83,ADE为0.67和SCLC为0.38。在相应于特异性为0.95的界定值3.47μg/L处,各型的灵敏度分别为SQC0.62,LC0.53,NSCLC0.51,ADE0.48和SCLC0.00。结论结果显示CYFRA21┐1是NSCLC较灵敏和特异的一个标志物。未观察到TNM各期间该标志物的平均水平有明显的差异;然而异常升高水平的患者的比例随病期的进展而显著增加,提示一系列检测CYFRA21┐1水平可能有助于监查NSCLC患者的疗效。 相似文献

Cytogenetic damage in operation theatre personnel 总被引:3,自引:0,他引:3
The study in a group of 24 (11 anaesthetists and 13 support staff) was planned to ascertain the cytogenetic risk in a group of theatre personnel who worked in various city hospitals. Their exposure in terms of duration of service vary from 3-30 years. The control group (n = 24) consisted of people with different occupations matched for possible confounding variables. Cytogenetic risk was assessed in terms of chromosome aberration and sister chromatid exchange in 72-hour lymphocyte cultures. A significant increase in the percentage of chromosome aberration was observed. The sister chromatid exchange was double that of the baseline value in 20% of the exposed individuals. These findings indicate the possible risk of cytogenetic damage for staff working in unscavenged rooms. 相似文献

Transient aphasia with lithium toxicity 总被引:1,自引:0,他引:1
J M Krakower 《Psychosomatics》1978,19(1):25-26
A case of transient aphasia in a 48-year-old woman is described. The aphasia occurred when progressive renal insufficiency led to accumulation of lithium to toxic levels, and was associated with well-known clinical findings of lithium toxicity. 相似文献

The paper considers the limiting factors in EEG enhancement in the presence of electrosurgery interference and presents a
design for a useful fibre-optic EEG monitoring instrument which is free from such problems as electrical shock (micro and
macroshock), patient burns and susceptibility to electrosurgery interference associated with conventional EEG monitors. 相似文献

We designed experiments in this study to test the hypothesis suggested by recent purification data that blood basophils comprise two populations of different density, which circulate in numbers characteristic for each human subject. Basophils were separated into two density bands by single step centrifugation on a discontinuous Percoll gradient. Band 1 cells were at the interface between plasma and Percoll of density 1.070 gm/ml. Band 2 cells were at the Percoll 1.070 to 1.080 interface. When the number of band 1 basophils was expressed as a percentage of the total in bands 1 and 2, this relative amount generally remained in a narrow range for blood obtained from the same donor on 3 successive days but differed markedly in different individuals. In a series of leukapheresis experiments, we demonstrated that the percentage of band 1 basophils in postleukapheresis venous blood was strikingly similar to the preleukapheresis value. If basophils that repopulated the leukapheresis-depleted circulation came from the bone marrow, we can conclude that blood levels of basophils in bands 1 and 2 are under physiologic control and that the two types of basophils are released in amounts characteristic for each human subject. Additional evidence for two distinct blood basophil populations was provided by histamine measurements. The histamine content per basophil was consistently higher in cells from band 1 than from band 2, the mean difference between pairs of values for 30 subjects being 0.3 +/- 0.04 pg or about 27% of the band 1 basophil histamine content of 1.1 pg. 相似文献

The major allergens present in mouse skin, serum, and urine have been identified. Skin extracts, serum, and urine were chromatographed, and the activities of the fractions were monitored by histamine release from the leukocytes of individuals sensitive to mice. Fractionation of skin extracts revealed two major allergens. The large allergen has a molecular weight of approximately 67,000 daltons and by biochemical and immunochemical criteria appears to be identical to mouse albumin. The smaller molecular weight allergen is approximately 17,000 daltons. The same two allergens are also found in mouse serum and mouse urine. Histamine release by leukocytes of individuals allergic to mice demonstrated that some individuals react predominantly to the large allergen, some to the small allergen, and one group of patients reacts to both allergens. 相似文献
