まとめ
緊急手術における処理されたEEGモニタリングは,麻酔を最適化し,血液動力学を改善することができます. しかし,BSRによって示された手術中のバースト抑制は,早期の術後の狂妄症のリスクの増加と関連しています.
科学分野:
- アネステシオロジー アネステシオロジー
- 神経科学は神経科学である.
- クリティカルケア・メディシン
背景:
- 緊急手術を受けた患者は,急性手術後の妄想症のリスクが高まります.
- エントロピー指数とバースト抑制比率 (BSR) を含む処理された電気脳波 (EEG) 監視は,麻酔投与を精製する可能性があるが,非選択的な設定では十分に研究されていない.
研究 の 目的:
- エントロピーのモニタリング,手術中のバースト抑制,および緊急手術後の72時間以内に早期の術後妄想の発生率との関連を調べる.
主な方法:
- 大人の緊急手術患者 (2022年3月〜2024年3月) の遡及的なコホート研究.
- 患者はエントロピーモニター (EG) と標準ケア (SG) のグループに分けられました.
- NEECHAMスコアを使用して評価された認知機能; 麻酔剤の投与量,爆破抑制,および血液動力学を分析した.
主要な成果:
- エントロピーをモニターした患者はセボフルーランとフェンタニルの投与量を低く,血液動力学的安定性が向上し,血管圧縮剤の必要性が減少しました.
- 早期の術後妄想 (NEECHAM ≤24) の発生率が高いのは,手術中のバースト抑制を受けた患者で観察された.
- BSR>15%または抑制期間>6分は,72時間の認知機能低下と強く相関しています.
結論:
- 緊急手術におけるエントロピー誘導麻酔は,正確な麻酔の定位と血液動力学的安定性を促進します.
- 外科手術中のバースト抑制パターンは,直接的な麻酔効果よりも神経認知の脆弱性を示す可能性があります.
- 処理されたEEGモニタリングは,緊急手術の有望性を示しており,さらなる将来の調査を正当化しています.

Entropy
36.4K
Salt particles that have dissolved in water never spontaneously come back together in solution to reform solid particles. Moreover, a gas that has expanded in a vacuum remains dispersed and never spontaneously reassembles. The unidirectional nature of these phenomena is the result of a thermodynamic state function called entropy (S). Entropy is the measure of the extent to which the energy is dispersed throughout a system, or in other words, it is proportional to the degree of disorder of a...

Entropy
3.6K
The first law of thermodynamics is quantitatively formulated via an equation relating the internal energy of a system, the heat exchanged by it, and the work done on it. A quantitative formulation of the second law of thermodynamics leads to defining a state function, the entropy.
When an ideal gas expands isothermally, the disorder in the gas increases. From the molecular perspective, the gas molecules have more volume to move around in.
Consider an infinitesimal step in the expansion, which...

Standard Entropy Change for a Reaction
25.0K
Entropy is a state function, so the standard entropy change for a chemical reaction (ΔS°rxn) can be calculated from the difference in standard entropy between the products and the reactants.

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.

Cognitive Dissonance

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Entropy and Solvation
8.5K
The process of surrounding a solute with solvent is called solvation. It involves evenly distributing the solute within the solvent. The rule of thumb for determining a solvent for a given compound is that like dissolves like. A good solvent has molecular characteristics similar to those of the compound to be dissolved. For example, polar solutions dissolve polar solutes, and apolar solvents dissolve apolar solutes. A polar solvent is a solvent that has a high dielectric constant (ϵ...
