まとめ
表面の浄化と消毒のモニタリング方法は,新生児集中治療室によって異なります. アデノシントリフォスファート (ATP) の基準値は異なっており,これらの重症治療環境における衛生評価に影響を与えました.
科学分野:
- 医療関連の感染予防
- 微生物学
- 新生児の集中治療
背景:
- 新生児集中治療室 (NICU) では,医療関連感染症を予防するために,効果的な表面の清掃と消毒が不可欠です.
- 衛生上の実践の有効性を監視することは,患者の安全のために不可欠です.
- アデノシン三酸 (ATP) 生物発光測定は,表面の清潔さを評価するために一般的に使用されます.
研究 の 目的:
- 異なる表面の浄化と消毒のモニタリング方法を相関させる.
- 2つのNICUでアデノシントリフォスファート (ATP) の値を比較する.
- 新生児の衛生管理の有効性を評価する.
主な方法:
- 864件の評価を含む相関研究が行われました.
- 方法には,ATPの定量化,視覚検査,有酸素コロニー数,Staphylococcus aureusの検出,および耐性検査が含まれていた.
- 衛生処置の前と後の評価が行われました.
主要な成果:
- 監視方法の相関は,単位と評価領域によって異なる.
- ユニットAでは,コロニー数とStaphylococcus aureus (カウンター) とATPとコロニー数 (インキュベーター) の間の相関が確認された.
- ユニットBでは,ATPとコロニー数 (注入ポンプ) の相関が観察されました. ATPの値はAユニットでは<28の相対光単位 (RLU) で,Bユニットでは<38のRLUでした.
結論:
- 異なるNICUでの衛生監視方法の相関関係には大きな違いがあります.
- アデノシントリフォスファート (ATP) の許容可能な表面の清潔さの値は,NICUによって異なります.
- これらの発見は,衛生監視と消毒プロトコルのユニット固有の最適化の必要性を強調しています.

7.3K
Cleaning, disinfection, and sterilization are the methods that help to break the infection chain and prevent disease.
Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...

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.

In healthcare, the chemical method of sterilization uses chemical sterilants to treat surgical instruments and medical supplies to help prevent the transmission of infectious pathogens to patients. Due to heat sensitivity, most medical supplies and equipment should not be exposed to high temperatures. These parts include rubber, plastic, glass, and other similar elements.
Using chemical sterilization rather than heat to clean out equipment is recommended. It eradicates and removes all bacteria,...

As used in a healthcare facility, sterilization destroys all microorganisms through physical or chemical methods. The physical method includes steam, dry heat, boiling water, and radiation.
Steam sterilization uses non-toxic, low-cost moist heat in the form of saturated steam under pressure, which is fast, microbicidal, and sporicidal, and quickly warms and penetrates fabrics. Autoclaves, or steam sterilizers, expose each item to direct steam contact for a predetermined time at the necessary...

The effectiveness of antimicrobial agents depends on various factors influencing their ability to eliminate microbial populations. Larger microbial populations require more time for complete eradication, emphasizing the importance of population size analysis when evaluating antimicrobial efficacy.Microbial resistance to antimicrobial agents varies significantly. Highly resilient microorganisms include endospores, gram-negative bacteria, and non-enveloped viruses, while prions are exceptionally...
