まとめ
経皮腎臓切除 (PCNL) の後の未分化ヘパリンは,高リスク患者の静脈血栓塞栓症 (VTE) の予防に安全であるようです. 確固たる証拠はないが,ヘパリンは出血の合併症を増加させずにVTEの発生を軽減する可能性がある.
科学分野:
- 腎臓科
- 血管 外科
- 薬理学について
背景:
- 経皮腎石切除 (PCNL) は大きな腎石に対する標準的な処置ですが,出血と静脈血栓塞栓 (VTE) のリスクがあります.
- 現在のガイドラインでは,出血の懸念と限られた証拠のために,薬理学的血栓予防を定期的に推奨していません.
- この研究では,中等から高リスクのPCNL患者のVTE予防のために,未分化ヘパリンを調査しています.
研究 の 目的:
- PCNLを患っている患者のVTE予防における未分化ヘパリンの安全性と有効性を評価する.
- ヘパリンを投与された患者と,早期出院で治療された患者の出血合併症と血栓塞栓を比較する.
主な方法:
- PCNLを患った202人の患者による遡及的なコホート研究.
- 患者は2つのグループに分けられた: 分割されていないヘパリン予防 (n=79) と薬理学的予防なしの早期出張 (n=123).
- 出血,輸血,合併症,および血栓塞栓性イベントを含む結果が比較されました.
主要な成果:
- ヘパリンを投与された患者は高齢で,BMIが高かった.
- 石の大きさ,手術の期間,ヘモグロビン値の低下,輸血率,または全体的な合併症の有意な違いは見つかりませんでした.
- 血液栓塞症は希少で,グループによって有意な差異はなかったが,早期歩行グループでは1人の死亡を含む3人のVTEが発生した.
結論:
- PCNL後の未分化ヘパリン血栓予防は安全であり,出血のリスクは高まりません.
- 中度から高リスクの患者では,血栓塞栓症の減少に役立つ可能性があることが示唆されています.
- 決定的な結論は,遡及的な設計とサンプルサイズによって制限されます.

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

Cardiac Catheterization I: Pre-Procedure Overview

Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...

Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...

Perform a comprehensive baseline assessment, including vital signs, heart and breath sounds, and a neurovascular assessment of the extremities, noting distal pulses, skin color, and temperature. Instruct the patient to fast for 8-12 hours before the procedure. Evaluate baseline laboratory...

Anticoagulant Drugs: Low-Molecular-Weight Heparins

Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...
