まとめ
血清ビカルボネート濃度が低いまたは高いセプシス患者は死亡リスクが高くなります. ビカルボネート濃度を24.0〜26.0mEq/Lの範囲に保つことは,敗血症の治療における結果を改善する可能性があります.
科学分野:
- クリティカル ケア 医療
- 生物化学
背景:
- セプシスは高い死亡率から 世界的に大きな健康問題となっています
- セプシス患者における血清バイカーボネート濃度と死亡率の正確な関係はよく確立されていません.
研究 の 目的:
- セプシスの成人の患者の血清バイカーボネート濃度と死亡率との関連を調べる
- セプシスの死亡リスクを減らすために最適な血清ビカルボネートレベルを特定する.
主な方法:
- MIMIC- IVデータベースの12, 744人の成人セプシス患者からのデータを利用した遡及コホート研究.
- 血清のバイカーボネート濃度はクインティルに分類され,28日間の死亡率が主なアウトカムであった.
- 多変量コックス回帰モデルと曲線フィッティング分析を使用して,二酸化炭素濃度と死亡率の関係を評価した.
主要な成果:
- 血清のバイカーボネート濃度と28日間の死亡率との間にU型の関連性が見られた.
- 低 (≤19.0 mEq/L) と高 (≥26.0 mEq/L) の二酸化炭素濃度の両方が死亡率の増加と関連していました.
- 最も低い死亡リスクは,バイカーボネート濃度が24. 0から26. 0mEq/ Lの患者で,転換点は25. 0mEq/ Lであった.
結論:
- 低炭水化物と高炭水化物の両方が,症患者の死亡率の増加と関連しています.
- 血清バイカーボネート濃度を24. 0から26. 0mEq/ Lの範囲で維持することは,敗血症患者のアウトカムを改善するために極めて重要です.
- これらの発見を検証し,治療的介入を探るため,さらなる研究が必要である.

Diagnosing Acidosis and Alkalosis
512
Diagnosing acid-base imbalances involves systematically analyzing arterial blood samples, focusing on three key measurements: pH, bicarbonate (HCO3−) concentration, and carbon dioxide partial pressure (PCO2). This analysis follows a four-step process that helps identify the imbalance's underlying cause and nature.
First, the pH level is assessed to determine whether the blood pH is normal (7.35–7.45), low (acidosis), or high (alkalosis).
Next, the PCO2 and...

Disorders of Acid-Base Balance
752
The human body maintains a precise pH range of arterial blood between 7.35 and 7.45. Deviations result in either acidosis (pH < 7.35) or alkalosis (pH > 7.45). These conditions are further classified as respiratory or metabolic disorders based on their underlying cause.
Respiratory Acidosis and Alkalosis
Respiratory acidosis occurs due to an increase in the partial pressure of carbon dioxide PCO2 in the blood. It often arises from shallow breathing or impaired gas exchange caused by...

Blood Studies I: ABG and VBG
730
Blood studies are critical in the medical field, enabling healthcare professionals to assess a patient's health status accurately. This page will focus on two significant blood studies: Arterial Blood Gas (ABG) and Venous Blood Gas (VBG).
Arterial Blood Gas (ABG)
Arterial Blood Gas (ABG) studies are crucial for assessing the lungs' ability to supply oxygen and remove carbon dioxide, reflecting the patient's ventilation status. They also help understand the kidneys' capacity to...

Acute Respiratory Failure-III
316
Hypercapnic respiratory failure, also known as Type 2 or ventilatory respiratory failure, is a severe condition characterized by the body's inability to effectively remove carbon dioxide (CO2) from the bloodstream. It leads to an arterial CO2 pressure (PaCO2) exceeding 45 mmHg and a blood pH above 7.35. This situation indicates that the body's ventilatory demand, or the ventilation needed to maintain normal PaCO2 levels, surpasses its supply or the maximum gas flow achievable without...

Bronsted-Lowry Acids and Bases
94.1K
The acid-base reaction class has been studied for quite some time. In 1680, Robert Boyle reported traits of acid solutions that included their ability to dissolve many substances, to change the colors of certain natural dyes, and to lose these traits after coming in contact with alkali (base) solutions. In the eighteenth century, it was recognized that acids have a sour taste, react with limestone to liberate a gaseous substance (now known to be CO2), and interact with alkalis to form neutral...
