まとめ
低用量アルフェンタニルは,小児患者の意識喪失を誘発するために必要なレミサゾラムの有効用量を大幅に減少させます. この組み合わせは,全身麻酔の誘導中の副作用の発生率を低下させます.
科学分野:
- 麻酔科
- 薬理学について
- 小児重症室
背景:
- レミマゾラムは,全身麻酔の誘導に使用される新種の超短期間作用ベンゾジアゼピンです.
- 麻酔療法の最適化は,小児患者の安全で効果的な処置鎮静に不可欠です.
- 補助薬の調査は 麻酔の必要性を減らし 患者の結果を改善する可能性があります
研究 の 目的:
- 小児患者の意識喪失に対するレミサゾラムの50%および95%の有効量 (ED50/ ED95) に対する低用量のアルフェンタニルの効果を決定する.
- アルフェンタニルの併用または併用なしでのレミマゾラムの安全性および有害事象プロフィールを評価する.
主な方法:
- 選択手術を受けた52人の小児患者 (3~12歳,ASA I-II) を対象とした前向きな研究.
- 患者はランダムに2つのグループに分けられ,グループAはアルフェンタニル (5μg kg−1) とレミサゾラム,グループCは塩分溶液とレミサゾラムを受けた.
- 意識の喪失を評価するために,観察者による警戒と鎮静の評価 (MOAA/S) スケールを使用し,ED50とED95を計算した.
主要な成果:
- レミマゾラムのED50は,対照群 (0. 340 mg kg−1) と比較してアルフェンタニル群 (0. 212 mg kg−1) で有意に低かった.
- レミマゾラムのED95は,アルフェンタニルの併用 (0. 265 mg kg−1) と対照群 (0. 434 mg kg−1) で著しく低下した.
- 副作用の発生率は,対照群 (39. 3%) に比べてアルフェンタニル群 (8. 3%) で大幅に低かった.
結論:
- 低用量アルフェンタニルは,小児麻酔誘導における意識喪失に成功するために必要なレミマゾラムの用量を大幅に減少させます.
- 低用量のアルフェンタニルとレミサゾラムの併用は,鎮静中の有害事象を減らすことにより,安全性プロファイルを改善します.
- この組み合わせは,小児の患者にとって より効率的で安全な麻酔戦略を提供する.

Parenteral Anesthetics: Overview
196
Intravenous anesthetics are drugs administered parenterally to induce anesthesia or sedation. Propofol is a widely used agent formulated as a 1% emulsion in soybean oil, glycerol, and egg phosphatide. It induces rapid anesthesia primarily due to its rapid distribution from the bloodstream to target tissues and is metabolized in the liver. However, it can cause significant pain on injection and hypertriglyceridemia. Fospropofol, a water-based prodrug of propofol, lacks these adverse effects.

Stages of General Anesthesia
674
Various sedation levels offer significant advantages in facilitating procedural interventions for patients undergoing medical or invasive surgical procedures. These levels span from anxiolysis to general anesthesia, providing a spectrum of sedative effects to cater to specific patient needs. Anxiolysis reduces anxiety and is achieved through minimal sedation, enabling patients to remain awake and responsive while feeling more at ease during the procedure. This level can benefit minor...

Inhalational Anesthetics: Overview
498
Inhalation anesthetics are drugs that induce general anesthesia upon inhalation. They work by increasing the sensitivity of GABAA receptors or inhibiting NMDA receptors, leading to a decrease in central nervous system activity. The depth of anesthesia can be rapidly adjusted by changing the concentration of the inhaled gas. Some common examples of inhalational anesthetics include volatile liquids like isoflurane, desflurane, sevoflurane and gases like xenon and nitrous oxide. Isoflurane, a...

General Anesthesia: Overview
282
Anesthesia is a medical procedure that uses drugs for CNS suppression to enable painless surgeries and procedures. The selection of anesthetics is influenced by their pharmacokinetic properties, side effects, and patient characteristics. Various types of anesthesia include general, local, regional, spinal, and inhalational.
General anesthesia induces unconsciousness in the whole body, while the others target specific areas or sensations. It is administered to minimize adverse effects, maintain...

Local Anesthetics: Clinical Application as Spinal Anesthesia
771
Spinal anesthetics are given during lower abdomen and limb surgeries to block sensory and motor neurons. They are administered in the mid to low lumbar regions, primarily acting on the cauda equina's nerve roots. The blockade level depends on the local anesthetic (LA) concentration. Usually, low LA concentrations are sufficient to block sensory fibers, while only high LA concentrations block motor fibers. Other factors like injection volume and speed, the patient's posture, and the drug...
