まとめ
抗血栓剤の使用は低く,高出血率を経験する透析患者ではしばしば中止されています. 腎不全患者におけるこれらの薬剤のリスクと利益のバランスを取るために,新しい戦略が必要である.
科学分野:
- ネフロロジーはネフロロジーを用います.
- 心臓病学 心臓病学
- 薬理学 薬理学とは
背景:
- 維持透析を受けている患者は心血管疾患のリスクが高いため,経口抗凝固剤 (OAC) や抗血小板治療 (APT) などの抗血栓療法が必要となる.
- 慢性抗血栓治療は透析患者の出血リスクを増加させるが,実際の薬剤使用パターンと出血リスクは十分に理解されていない.
研究 の 目的:
- 口服抗凝固剤 (OAC) と抗血小板治療 (APT) の使用パターンを調査する.
- ヘモダイアリス (HD) または腹腔内透析 (PD) を受けている患者の抗血栓療法に関連した出血イベントのリスクを評価する.
主な方法:
- 国際透析結果と実践パターン研究 (DOPPS) と腹腔内DOPPS (PDOPPS) のコホートから得られたデータの遡及分析.
- HD患者27,612人,PD患者5,289人を含め,人口統計,併発症,OAC,APTの使用を分析した.
- 記述的分析とKaplan-Meier法を使用して,薬剤の使用,中止,出血の複合的なアウトカムを評価しました.
主要な成果:
- ベースラインのOACとAPTの使用は低い:HD患者の9%と10%,PD患者の4%と7%.
- 抗血栓剤の使用者は,心臓血管疾患の anamnesis がより多い高齢者でした.
- 36ヶ月後,OACとAPTの持続率はそれぞれ57%と53%でした. 100患者年あたりの複合出血率は,OACで8.6,HD患者でAPTで5.6,PD患者でOACで12.0,PD患者でAPTで6.1でした.
結論:
- アンチトロンボティック薬は,HDまたはPDを投与している患者には,めったに処方されず,しばしば中止されます.
- 主要出血事件の発生率は,透析患者集団の抗血栓剤使用者の中で高い.
- 透析中の腎不全患者における抗血栓剤のリスク・利益プロフィールを最適化するために,新しい戦略が必要である.

Extracorporeal Removal of Drugs: Peritoneal Dialysis and Hemodialysis
551
Patients with end-stage renal disease (ESRD) or those experiencing drug overdose often require extracorporeal methods to eliminate accumulated drugs and metabolites. Hemoperfusion, hemofiltration, and dialysis are the primary techniques to rapidly remove harmful substances without disrupting the patient's fluid and electrolyte balance. For those with compromised renal function, dosage adjustments of concurrent medications may be necessary during extracorporeal drug removal.Dialysis is a process...

Peritoneal dialysis (PD) is a procedure that facilitates the exchange of solutes, waste products, electrolytes, and excess fluid between the blood in the peritoneal capillaries and a dialysis solution introduced into the peritoneal cavity.Principles of Peritoneal Dialysis (PD)Diffusion: Waste products such as urea and electrolytes move from high concentrations in the blood to low concentrations in the dialysate across the peritoneal membrane. This mechanism is driven by the concentration...

Peritoneal dialysis, or PD, utilizes the peritoneal membrane as a filter to eliminate excess fluid and waste products. Effective nursing management is essential for ensuring patient safety, preventing complications, and promoting optimal function of the peritoneal dialysis process.Assessment and MonitoringNurses must thoroughly assess the patient before, during, and after each dialysis session. Regular monitoring includes vital signs, daily weight, fluid intake and output, and laboratory values...

Renal failure occurs when the kidneys lose their ability to filter waste products from the blood effectively. It can be classified into two types: acute renal failure (ARF) and chronic renal failure (CRF).
Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...

Dialysis

Dialysis is a diffusion-based purification process that separates analyte molecules from a complex matrix. This is accomplished by allowing molecules in the solution to pass through a semipermeable membrane into a liquid on the other side. The membrane is usually made of cellulose acetate or cellulose nitrate, and the second liquid must be miscible with the solution. Ions (e.g., chloride or sodium) or organic molecules (e.g., glucose) can pass through the membrane pores, which generally have...
