まとめ
早産児のオピオイド使用は神経発達障害のリスクを増加させるようには見えない. しかし,証拠は非常に限られており,いくつかの研究は,運動能力に潜在的な悪影響を示唆しています.
科学分野:
- 新生児科学
- 発達に関する小児科
- 薬理学について
背景:
- オピオイドは新生児集中治療室で 痛みや苦痛の管理のために 頻繁に投与されています
- 小児の神経発達に対するオピオイドの潜在的悪影響については懸念がある.
研究 の 目的:
- オピオイドが早産児の神経発達に及ぼす影響を調査するランダム化対照試験 (RCT) と観察試験 (OSS) を体系的に検討する.
主な方法:
- コクラン・コラボレーションのガイドラインに沿った体系的なレビューが行われました.
- ランダム化制御試験 (RCT) と観察研究 (OSS) を含む.
- 可能な限り定量合成 (プーリング) が用いられ,他のデータについては定性合成が用いられた.
主要な成果:
- このレビューには,乳児3173人を対象とした16件の研究 (13件のOS,3件のRCT) が含まれていた.
- 神経発達障害のリスク増加は認められなかった (確率は非常に低い).
- 2~3歳のオピオイドに曝された乳児の運動スコアは低下し,定性分析ではオピオイドの効果が変化していることが示された.
結論:
- オピオイドが早産児の神経発達に及ぼす影響に関する現在の証拠は不確実です.
- 入手可能な証拠の確実性は"非常に低い"と評価されています.

Factors Affecting Drug Response: Overview
2.4K
When it comes to infants and young children, they are typically administered smaller doses of medication in comparison to adults. This is primarily because their organ functions still need to fully develop, meaning their bodies are not as efficient at metabolizing or eliminating drugs. Additionally, their blood-brain barrier is more permeable than in adults. As a result, high concentrations of drugs can easily penetrate the central nervous system (CNS), potentially leading to neurological...

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...

Opioid Analgesics: Synthetic and Semisynthetic Opioids
426
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...

Opioid Analgesics: Morphine and Other Natural Cogeners
361
Opioids are a class of drugs that mimic endogenous opioid peptides and act on opioid receptors, and help in pain relief. These compounds are classified as natural, synthetic, or semi-synthetic. Natural opioids, like morphine, codeine, and thebaine, are derived from the opium poppy plant (Papaver somniferum or Papaver album) and are termed opiates. Synthetic opioids are artificial, while semi-synthetic opioids combine natural and synthetic compounds. Morphine, a prototypical opioid, possesses a...

Opioid Receptors: Overview
1.8K
Opioid receptors, including the mu (μ, MOR), delta (δ, DOR), and kappa (κ, KOR) types, belong to the rhodopsin family of G protein-coupled receptors. These receptors are located throughout the central and peripheral nervous systems and in non-neuronal tissues such as macrophages and astrocytes. Opioid receptor ligands can be categorized into agonists or antagonists. Highly selective agonists include [d-Ala2, MePhe4, Gly(ol)5]-enkephalin or DAMGO for MOR, [D-Pen2,...

Teratogenicity
2.7K
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
