まとめ
外科手術中の手術中の高血糖血症,または手術中の高血糖血症は,心臓手術患者の手術後の感染症のリスクを独立して増加させます. 乳糖を2.7mmol/L未満に保つことは,感染リスクを減らす可能性があります.
科学分野:
- 心臓病学 心臓病学
- 外科感染症予防 手術感染予防
- クリティカルケア・メディシン
背景:
- 手術後の感染症は,心臓外科における重要な懸念事項である.
- 心肺バイパス (CPB) は,感染リスクに影響を与えるかもしれない生理学的変化と関連しています.
- 術後の乳酸塩濃度は,組織ヒポパーフュージョンと有害な結果の潜在的マーカーです.
研究 の 目的:
- 術後感染リスクの独立した予測因子であるかを判断する.
- CPBを患っている心臓外科手術患者の感染リスクの増加に関連した手術中の血中乳酸濃度の値を特定する.
主な方法:
- CPBを受けた4970人の心臓外科手術患者の遡及的研究.
- 血液中乳糖値>2.0 mmol/L. として定義される内手術性高乳糖血症.
- ハイパーラクタテミアと術後の感染症の関連性を評価するための統計的分析,混同因子調整.
主要な成果:
- 手術後の感染症は,患者の14.49%で発生しました.
- 感染した患者は,手術後の乳酸塩濃度ピークがかなり高かった (3.5対2.6 mmol/L).
- 術後高乳糖血症は,手術後の感染症のリスク1.49倍増加と独立して関連していました (aOR: 1.49; 95%CI: 1.18-1.91).
- 約2.7mmol/Lの乳糖値のピーク値は,感染リスクの上昇と関連していた.
結論:
- 術内高乳糖血症は,CPBによる心臓外科手術における術後の感染症の独立したリスク因子です.
- 2.7 mmol/L未満の手術中の血液中乳酸塩レベルをターゲットにすることは,手術後の感染率を減らすための戦略である可能性があります.

Genome-wide Association Studies-GWAS
15.8K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

Cardiopulmonary Resuscitation I: Adult
773
Cardiopulmonary resuscitation, or CPR, is a life-saving emergency procedure performed when a person's heart has stopped beating or they are no longer breathing. The foundation of CPR is Basic Life Support (BLS), which focuses on the early recognition of cardiac arrest, the immediate start of high-quality chest compressions, and the timely use of an automated external defibrillator (AED).Assessing Responsiveness and Checking the Carotid PulseWhen approaching an unresponsive person, first ensure...

Blood Studies for Cardiovascular System I: Cardiac Biomarkers
928
Cardiac biomarkers are enzymes, proteins, and hormones released into the blood when cardiac cells are injured. They are powerful tools for triaging.
The essential diagnostic tools for detecting myocardial necrosis and monitoring individuals suspected of having acute coronary syndrome (ACS) include:
Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...

Associative Learning
1.5K
Associative learning is a fundamental concept in behavioral psychology, wherein a connection is established between two stimuli or events, leading to a learned response. This process is critical in understanding how behaviors are acquired and modified. Conditioning, the mechanism through which associations are formed, can be divided into two main types: classical conditioning and operant conditioning, each elucidating different aspects of associative learning.

Association Areas of the Cortex
9.5K
Association areas are regions of the cerebral cortex that do not have a specific sensory or motor function. Instead, they integrate and interpret information from various sources to enable higher cognitive processes such as memory, learning, and decision-making. Some key association areas include the following:
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...

Cardiopulmonary Resuscitation III: AED Use
763
Introduction to AEDAn Automated External Defibrillator (AED) is a portable medical device that analyzes the heart's rhythm and, if necessary, delivers an electrical shock to help the heart re-establish an effective rhythm during sudden cardiac arrest (SCA). SCA occurs when the heart suddenly and unexpectedly stops beating, leading to a loss of blood flow to the brain and other vital organs. In such emergencies, time is of the essence, and using an AED, combined with Cardiopulmonary...
