主な方法:
- 複数のデータベース (PubMed,Embase,Scopusなど) で体系的な文献検索が行われました. 対象となる研究を特定する.
- EDTA (403人) と対照群 (425人) を比較した8つの研究をメタ分析した.
- CRBSI/ CLABSI,カテーテル入植,カテーテル生存,および死亡率の相対リスクと確率比を計算した.
主要な成果:
- EDTAは,CRBSI/ CLABSIの発生率 (RR: 0. 18; P < 0. 001) とカテーテル入植率 (OR: 0. 11) を著しく減少させた.
- EDTA (OR: 3. 77; P < 0. 02) で治療された血液透析患者では,カテーテル生存率の有意な改善が観察されました.
- EDTAは血栓解消治療や全因死亡率に有意な効果を示さなかった.
結論:
- EDTAは,CRBSI/CLABSIとカテーテルコロニゼーションを減らすのに有効なカテーテルロックソリューションです.

Parentral Nutrition: Centeral and Peripheral Parental Nutrition
297
Parenteral Nutrition (PN) delivers essential nutrients directly into the bloodstream, bypassing the digestive system. It is commonly used for individuals with severe digestive disorders or conditions that prevent normal nutrient absorption.
PN can be administered through two primary routes:
1. Central Parenteral Nutrition (CPN):
CPN involves delivering a high concentration of nutrients through a large vein. This is typically achieved using a Peripherally Inserted Central Catheter (PICC) or,...

EDTA: Auxiliary Complexing Reagents
664
EDTA titrations are usually carried out in highly basic conditions, where the fully deprotonated form of EDTA, Y4−, actively complexes with the free metal ions in the solution. Several metal ions precipitate as hydrous oxide (hydroxides, oxides, or oxyhydroxides) under these conditions, lowering the concentration of free metal ions in the solution. For this reason, auxiliary complexing agents or ligands such as ammonia, tartrate, citrate, or triethanolamine are used in EDTA titrations to...

EDTA: Chemistry and Properties
2.2K
Polydentate ligands are most widely used in complexometric titrations because they form more stable complexes with the metal ions than mono- or bidentate ligands due to the chelate effect. Examples of polydentate ligands are ethylenediaminetetraacetic acid (EDTA), crown ethers, and cryptands. The most important feature of optimal polydentate ligands is the ability to form 1:1 complexes in a single-step process. Amino carboxylic acid derivatives are frequently used as complexing agents. EDTA is...

Effects of EDTA on End-Point Detection Methods
343
Different methods, such as visual observance of metal-ion indicators, spectroscopic techniques, and potentiometric methods, can determine the endpoint of an EDTA titration.
In the visual method, metal-ion indicators (metallochromic dyes), which have distinct colors in their free and complex forms, are added to the mixture to signal the titration's end point. They form stable complexes with metal ions, but these complexes are weaker than the corresponding metal–EDTA complexes. As a...

Masking and Demasking Agents
2.6K
EDTA titrations may necessitate masking and demasking agents to temporarily protect a particular metal ion in a mixture from the EDTA reaction. These agents facilitate the sequential analysis of the metal ions by forming stable complexes with some—but not all—metal ions during certain steps.
There are many masking agents, such as cyanide, fluoride, triethanolamine, thiourea, and 2,3-bis(sulfanyl)propan-1-ol (formerly 2,3-dimercapto-1-propanol), with the masking agent chosen based on...

EDTA: Direct, Back-, and Displacement Titration
3.3K
The EDTA titration types for metal ion analysis include direct titration, back-titration, and replacement titration.
Direct titration involves buffering the metal ion solution to the desired pH and directly titrating with standard EDTA until the endpoint. The optimum pH ensures a large conditional formation constant of metal−EDTA and visibility of the free indicator color in the solution. In addition, auxiliary complexing reagents are used to prevent the precipitation of metal hydroxides...
