まとめ
プロトコライズされた鎮静療法に毎日の鎮静中断を加えた結果,重症の成人では,機械呼吸器やICU滞在期間を短縮することはありませんでした. この戦略はまた,鎮静剤とオピオイドの投与量と看護師の作業量を増加させました.
科学分野:
- クリティカルケア・メディシン
- 薬理学 薬理学とは
- クリニック・トライアル 臨床試験
背景:
- プロトコライズされた鎮静と毎日の鎮静中断は,機械呼吸器と集中治療室 (ICU) の滞在期間を管理するための重要な戦略です.
- これらの鎮静管理テクニックを組み合わせることで,患者のアウトカムを改善すると仮定されました.
研究 の 目的:
- 診断された鎮静剤のみの効果と,診断された鎮静剤を,重症で機械呼吸器を施した患者の毎日の鎮静剤中断と組み合わせた効果を比較する.
主な方法:
- 16のICUで430人の成人患者が参加したランダム化制御試験です.
- 患者は,プロトコライズされた鎮静剤か,毎日中断したプロトコライズされた鎮静剤を投与され,看護師は軽度の鎮静剤を達成するために注入量を定量化しました.
- キーアウトカムは,エクスチューブが成功するまでの時間であり,二次的なアウトカムには,ICU/入院,鎮静剤の投与,妄想,ワークロードが含まれていた.
主要な成果:
- グループ間の成功エクストゥベーションまでの時間 (中位は7日) は有意な差異はなかった.
- 集中治療室と病院での滞在期間も同様でした.
- 日々の中断グループでは,鎮静剤とオピオイドの投与量が増加し,看護師の労働負荷 (VASスコア) が増加しました.
- 妄想症の発生率と非意図的な内管切除の割合は,有意に異なるものではありませんでした.
結論:
- 機械呼吸器を使用した成人の場合,プロトコル化された鎮静療法に毎日鎮静中断を加えても,機械呼吸器の持続時間やICU滞在を短縮することはありませんでした.
- この結果から,この組み合わせのアプローチは,追加の利点を提供しない可能性があり,薬の使用と労働負荷を増加させる可能性があることが示唆されています.

Stages of General Anesthesia
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...
Parenteral Anesthetics: Overview
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.
Sedatives and Hypnotics: Overview
Sedatives are drugs that alleviate anxiety, while hypnotics induce sleep. Both classes of medication suppress neuronal activity, leading to a calming effect for sedatives and facilitating sleep for hypnotics.
Sedative-hypnotics are categorized into barbiturates, benzodiazepines (BZDs), and non-benzodiazepines or Z-drugs. These drugs work by suppressing central nervous system activity, and this suppression is dose-dependent. Older sedative medications, like barbiturates, follow a linear curve in...

Sedatives and Hypnotics Drugs: Miscellaneous Agents
Sedatives and hypnotics encompass a wide range of substances, each with its unique mechanism of action, uses, and potential adverse effects.
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...

Skeletal Muscle Relaxants: Adverse Effects
Skeletal muscle relaxants are widely used for muscle paralysis and relieving pain following any muscle injury or stiffness. However, depending on the drug type, they can have adverse effects that range from mild to severe. Usually, nondepolarizing neuromuscular blockers have minimal side effects. For example, drugs like d-tubocurarine, cisatracurium, and rocuronium cause hypotension, whereas drugs like baclofen, when stopped abruptly, can lead to the recurrence of spastic conditions.

General Anesthesia: Overview
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...
