まとめ
オピオイドフリー麻酔 (OFA) は,オピオイドベースの麻酔 (OBA) と比較して,手術後の吐き気や嘔吐 (PONV) と鎮痛剤の必要性を有意に軽減します. OFAは手術後の回復の質も改善し,安全で効果的な麻酔戦略を提供します.
科学分野:
- 麻酔科
- 手術 の 結果
- 薬理学について
背景:
- オピオイドベースの麻酔 (OBA) は,手術後の吐き気 (PONV) と依存症を含む重大な副作用に関連しています.
- オピオイドフリー麻酔 (OFA) はこれらの副作用を軽減する潜在的な代替手段です.
- 手術後の治療を最適化することは 手術患者のケアにおける重要な目標です
研究 の 目的:
- 手術後の結果に対するOFAの影響を,OBAと比較して体系的に評価する.
- 最小侵襲的手術や従来の手術を含む様々な種類の手術におけるOFAの有効性を調査する.
- 麻酔の戦略に関する臨床的意思決定のための根拠に基づいたガイドラインを提供すること.
主な方法:
- OFAとOBAを比較したランダム化対照試験 (RCT) の体系的なレビューとメタ解析.
- 2025年5月までの主要なデータベース (PubMed,Web of Science,Embase,Cochrane Library) での包括的な文献検索
- 主要アウトカム:PONVの発生率 2次結果:手術後の回復,痛みスコア (VAS,NRS),鎮痛の必要性,および有害事象
主要な成果:
- 5426人の患者を含む68件のRCTで,OFAはPONV,吐き気,嘔吐,およびOBAと比較して術後の鎮痛の必要性を有意に減少させた.
- OFAは24時間後のNRSの痛みのスコアが低いと関連していたが,異質なアウトカムではVASの痛みのスコアが有意に低下しなかった.
- 研究の3分の2以上は,OFAが術後の回復の質 (QoR-40) を改善することを示したが,一部では,エクストゥベーション時間が長くなる可能性があると指摘した.
結論:
- OFAは安全で効果的な麻酔戦略で,PONVと鎮痛剤の必要性を大幅に軽減します.
- 手術後の回復の質を向上させるのに有益であることが示されています.
- 特定の回復指標に対するOFAの効果を確認し,臨床応用を最適化するために,さらに高品質な研究が必要である.

Opioid Analgesics: Synthetic and Semisynthetic Opioids
421
Synthetic and semisynthetic opioids are pivotal in pain management and tackling opioid addiction. Semisynthetic opioids, including morphinans (morphine derivatives), oxycodone, oxymorphone, hydrocodone, and hydromorphone, have improved pharmacokinetic profiles compared to morphine. Additionally, heroin and 6-MAM (6-Monoacetylmorphine) show better CNS penetration than morphine due to heightened lipid solubility. Hydromorphone, a potent opioid, undergoes hepatic metabolism to form the active...

General Anesthesia: Overview
283
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...

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.

Analgesia and Pain Management
788
Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...

Local Anesthetics: Clinical Application as Epidural Anesthesia
498
Epidural anesthetics are administered in the fat-filled epidural space, the outermost part of the spinal canal. This technique is commonly employed for pain management and anesthesia during lower abdomen and pelvis surgeries or labor and delivery.
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...

Stages of General Anesthesia
681
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...
