まとめ
重症の患者では,バランスの取れた溶液は,塩水と比較して90日間の生存を有意に改善しませんでした. この研究は,集中治療室 (ICU) での液体蘇生にはバランスの取れたソリューションが優れないことを示唆しています.
科学分野:
- クリティカル ケア 医療
- 腎臓科
- 液体 蘇生
背景:
- 静脈内注射液は集中治療室 (ICU) の患者にとって不可欠です.
- 以前の研究では,死亡率や急性腎臓損傷など,さまざまな種類の液体の患者の結果への影響について疑問を投げかけていました.
研究 の 目的:
- 重症患者の90日生存率の改善におけるバランスのとれた結晶溶液と塩水 (0. 9%) の有効性を比較する.
主な方法:
- ブラジルの75のICUで,ダブルブラインド,因数学的,ランダム化臨床試験が行われました.
- 液体の膨張が必要で,有害な結果の危険因子を持つ重症患者は,バランスの取れた溶液または塩分溶液のいずれかを投与するためにランダムに割り当てられました.
- 測定された主なアウトカムは90日生存期でした.
主要な成果:
- 均衡溶液群 (26. 4%の死亡率) と塩素群 (27. 2%の死亡率) の間で,90日間の死亡率において有意な差は認められなかった.
- 死亡率に対する調整された危険比率は0. 97 (95%CI,0. 90-1. 05) で,バランスの取れた溶液の統計的に有意な利点はないことを示した.
- 治療に関連した重度の有害事象は報告されなかった.
結論:
- 0. 9% の塩溶液と比較して,液体蘇生を必要とする重症患者の90日間の死亡率は有意に減少しませんでした.
- これらの発見は,この特定のバランス溶液を,この患者集団の塩分溶液よりも日常的に使用することを支持するものではありません.

Disorder of Water Balance
1.7K
Water balance disorders are medical conditions that occur when there is a deviation from the body's water volume or osmolarity, disrupting normal homeostasis and leading todehydration, hypotonic hydration, hyperhydration, edema, or water intoxication.
Dehydration
Dehydration occurs when the body loses fluids (particularly water).
Causes:
The major causes of dehydration include excessive sweating, fever, vomiting, diarrhea, and diuresis.
Signs and Symptoms:
Symptoms primarily include intense...

Hemodialysis II: Procedure and Complications
203
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,...

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...
