Responses to Heat and Cold Stress02:45

Responses to Heat and Cold Stress

14.8K
Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.

Cold Weather Concreting01:27

Cold Weather Concreting

384
When freshly poured concrete is exposed to freezing temperatures before it has set, the water within the concrete can freeze. This expansion disrupts the setting process, delays chemical reactions necessary for hardening, and increases the volume of pores within the hardened concrete, which weakens its overall structure. If the concrete manages to reach an appreciable strength before it freezes, the damage can be somewhat mitigated.
To counteract the negative impacts of cold weather, ensuring...

Masonry in Cold and Hot Weather Conditions01:21

Masonry in Cold and Hot Weather Conditions

348
In cold weather, masonry construction requires specific precautions to ensure mortar does not freeze before curing, as this can significantly weaken its strength and watertightness. Mortar temperature should be maintained between 60°F and 80°F to support proper hydration and curing. Below 40°F, mortar water must be heated, but should not exceed 120°F as high temperatures can reduce mortar's compressive and bond strength.
Other key practices include keeping masonry units...

Hand hygiene

6.0K
Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

Predicting Reaction Outcomes

10.9K
Kinetics describes the rate and path by which a reaction occurs. In contrast, thermodynamics deals with state functions and describes the properties, behavior, and components of a system. It is not concerned with the path taken by the process and cannot address the rate at which a reaction occurs. Although it does provide information about what can happen during a reaction process, it does not describe the detailed steps of what appears on an atomic or a molecular level. On the other hand,...

Outcomes of Glycolysis01:13

Outcomes of Glycolysis

107.3K
Nearly all the energy used by cells comes from the bonds that make up complex organic compounds. These organic compounds are broken down into simpler molecules, such as glucose. As a result, cells extract energy from glucose over many chemical reactions—a process called cellular respiration.
Cellular respiration can occur aerobically (with oxygen) or anaerobically (without oxygen). In the presence of oxygen, cellular respiration starts with glycolysis and continues with pyruvate...

まとめ

冷湿布デバイス(CTD)は、アイスパックと比較して、手の外科手術患者の疼痛緩和とアドヒアランスを大幅に改善しました。オピオイドの使用量は同様でしたが、CTDは術後の疼痛管理に有望です。

科学分野:

  • 整形外科;疼痛管理;凍結療法

背景:

  • 冷湿布デバイス(CTD)は、整形外科手術後の鎮痛と腫脹軽減を提供します。;術後の疼痛とオピオイド使用におけるCTDとアイパックの比較データは限られています。;本研究では、手根中手関節形成術(CMC)および遠位橈骨開放整復内固定術(ORIF)後のCTDによる患者満足度とオピオイド使用量を評価しました。

研究 の 目的:

  • 術後の疼痛管理におけるCTDと従来のアイパックの効果を比較すること。;凍結療法プロトコルへの患者のアドヒアランスを評価すること。;特定の手術を受けた患者のオピオイド消費量を評価すること。

主な方法:

  • CMC関節形成術または遠位橈骨ORIFを受けた124名の手術患者(うち92名が組み入れ)の前向き分析。;CTD群とアイスパック群間での疼痛緩和、凍結療法アドヒアランス、オピオイド使用量に関する患者報告転帰の比較。;2023年6月から2025年2月までのデータ収集。

主要な成果:

  • CTDユーザーは、CMC関節形成術患者において、有意に高い疼痛緩和(9.56/10対3.42/10)とアドヒアランス(1日3セッション以上)を報告しました。遠位橈骨ORIF患者では、術後3日および7日においてCTDの使用率が高く(それぞれ96%対11%、88%対11%)、両処置ともCTDとアイスパック群間でオピオイド消費量に有意差は見られませんでした。

結論:

  • CTDの使用は、CMC関節形成術および遠位橈骨ORIF後の疼痛緩和と凍結療法アドヒアランスを向上させます。;CTDは、手および手首の手術における術後の疼痛管理の貴重な補助となる可能性があります。;さらなる研究により、オピオイド使用量に影響を与える可能性のある最適なCTDプロトコルを検討することができます。
