まとめ
ポリヘクサニドベタイン (PHMB- B) を用いた新しい出口部位ケアプロトコルは,小児の血液透析患者におけるカテーテル関連細菌血症 (CRB) を有意に減少させた. この研究は,PHMB-Bがトンネル入りのキャセターを持つ子供における感染症の合併症を予防するのに有効であることを示唆しています.
科学分野:
- 小児腎臓科
- 感染症
- 生物医学工学
背景:
- カテーテル関連の感染症は小児の血液透析患者の主要な合併症です.
- ポリヘクサニドベタイン (PHMB-B) は,バイオフィルムと傷の治癒に有効なバイオシードです.
- 血液透析の退去部でのPHMB-Bの証拠は不足しています.
研究 の 目的:
- 小児の血液透析患者における,PHMB- Bを用いた新しい出口部位ケアプロトコルの,カテーテル関連細菌血症 (CRB) と出口部位感染 (ESI) 率に対する影響を評価する.
- PHMB-Bプロトコルの実施前と後の感染率を比較する.
主な方法:
- 2017年1月から2020年12月までのトンネルカテーテルを使用した小児患者の逆行図分析.
- (クロルヘキシジン) プロトコル導入前と後のCRBとESIの発生率の比較
- 感染症状によるCRBと, 性出血または赤血腫によるESIを定義します.
主要な成果:
- CRBの発生率は1000カテーテル日当たり2. 64から0. 41に大幅に低下した (p=0. 041).
- ESI率は1000カテーテル用日あたり2. 37から1. 25に減少した (有意ではない).
- PHMB- Bで皮の不良反応やカテーテル材料の分解は観察されなかった.
結論:
- ポリヘクサニドベタイン (PHMB- B) は小児の血液透析におけるカテーテル関連感染症の予防に有望である.
- PHMB-Bを用いた新しいプロトコルは,患者の安全性を向上させるための貴重なツールとなるかもしれません.
- 長期的有効性やより広範な応用が 検討されるかもしれません

Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

Hemodialysis II: Procedure and Complications
128
DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...

Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.

Hemodialysis I: Introduction
282
Hemodialysis (HD) is a medical treatment that artificially removes waste products, excess fluids, and toxins from the blood when the kidneys are no longer able to perform these functions effectively. In this process, blood is filtered through a semipermeable membrane, allowing for the selective removal of waste while preserving necessary components like blood cells and proteins. Hemodialysis is typically performed in patients with end-stage renal disease (ESRD) or severe kidney...

The nursing management of a patient undergoing hemodialysis includes several critical steps, starting with a thorough assessment before the procedure.Before the Hemodialysis ProcedureFirst, record the patient's vital signs—blood pressure, heart rate, respiratory rate, and temperature—to establish a baseline. This baseline is essential for detecting conditions such as hypotension that could impact the patient's response to dialysis. Document the patient's pre-dialysis weight, as this...
