概括
这项研究发现,较小的角膜切口和基甲基纤维素 (HPMC) 减少了白内障手术期间的气溶生成. 玻璃切除手术过程中,除了泄漏的三门外,气溶的产生最小,这强调了感染控制的端口完整性.
科学领域:
- 眼科和外科气溶科学
- 在外科环境中的感染控制.
背景情况:
- 眼内程序,如化和帕斯普拉纳视切除术 (PPV),可以产生传染性气溶.
- 关于在人白内障和玻璃切除手术期间产生气溶的数据有限,特别是关于伤口结构和感染控制.
研究的目的:
- 为了量化人体尸体眼中的化过程中的滴滴气溶生成.
- 评估角膜切口大小 (2.2毫米对2.75毫米) 对气溶产生的影响.
- 为了确定基甲基纤维素 (HPMC) 是否减少气溶的产生,并在PPV步骤中测量气溶.
主要方法:
- 使用高灵敏度光学粒子光谱仪 (POPS) 测量人体尸体眼中的液滴气溶 (0.12-8.00微米).
- 经过2.2毫米和2.75毫米角膜切口的测试,具有或没有HPMC涂层.
- 在23度PPV的单个步骤中监控气溶生成.
主要成果:
- 与较小的 (2.2 mm) 切口相比,法化产生了更高的平均颗粒数度 (PNC),具有更大的 (2.75 mm) 切口.
- 应用HPMC显著降低了两种切口大小的气溶数量 (例如2.75毫米:493厘米-3至61厘米-3).
- 在PPV期间没有检测到有意义的气溶增加,除了通过泄漏的三角管输入空气期间.
结论:
- 这项研究是第一个使用高灵敏度光谱仪在整个尸体人眼中量化发酵和PPV过程中的空气中的颗粒.
- 较小的角膜切口 (2.2毫米) 和HPMC应用似乎可以减少白内障手术期间滴滴气溶的产生.
- 在PPV过程中泄漏的特洛卡可以产生滴滴气溶,这强调了保持端口完整性的必要性.

00:52Washing, Drying, and Ignition of Precipitates
After filtration, the precipitate is washed to remove coprecipitated impurities and any remaining mother liquor. Colloidal precipitates, such as silver chloride, are washed with an electrolyte (such as dilute nitric acid) to prevent the peptization of the precipitate. In the case of slightly soluble precipitates, the wash solution contains a common ion to reduce solubility. Lead sulfate, which is slightly soluble in water, is washed with dilute sulfuric acid. Similarly, wash solutions may be...
01:10Volatilization
Volatilization gravimetry is an analytical technique that measures the mass lost due to the volatilization of the substance. This technique is used to estimate the amount of volatile material in a sample. To perform this method, heat a known amount of the sample to a high temperature in a crucible or other suitable vessel. The volatile substance in the sample evaporates, and the vapor is completely expelled from the crucible either by heating the sample or bubbling a stream of inert gas through...
