まとめ
骨格外科手術の患者における術後の痛み管理の実現可能性が示されています. この研究では 標準的な治療と比較して 類似した痛みとオピオイド使用の結果が示され BUPはさらなる調査を必要としていることを示唆しています
科学分野:
- 麻酔学と痛み管理
- 薬理学について
- 整形 術
背景:
- オピオイドは手術後の整形外科の痛みに対して標準的ですが,部分的アゴニストオピオイドであるブプレノルフィン (BUP) は,急性疼痛に対する有効性と安全性が証明されているにもかかわらず,十分に使用されていません.
- BUPはオピオイド使用障害の治療でよく知られていますが,急性疼痛管理におけるその可能性はほとんど未知のままです.
研究 の 目的:
- 整形外科手術を受ける入院患者に口腔BUPを投与する可能性を評価する.
- 標準の鎮痛剤の併用で口腔BUPを投与された患者の痛みの管理結果を調査する.
- 1日2回口腔BUPを投与された患者のサブセットでのアウトカムを具体的に調べる.
主な方法:
- 退役軍人の健康管理局で実施された遡及コホート研究.
- 麻酔医の裁量で手術前ブカルBUPを受けた35人の整形外科患者のグラフレビュー.
- 痛みの結果とBUP投与の実現可能性の探索分析
主要な成果:
- 大規模な整形外科手術を受けたオピオイド未使用の患者では,経口BUP投与が可能であった.
- BUPを投与された患者と通常の治療のみを受けた患者の間では,痛みの結果とオピオイドの総摂取は比較可能でした.
- Buccal BUPは患者および看護スタッフによって良好に受け入れられ,フルアゴニストオピオイドと互換性があり,安全性に関する懸念はありませんでした.
結論:
- 慢性疼痛に承認されたBUPの口腔製剤は,骨格外科における急性疼痛管理に先ほど研究されていなかった.
- この研究は,遡及的な設計と小さなサンプルサイズによって制限されていたが,口腔BUPは多様性鎮痛のための実行可能な選択肢であることを示唆している.
- 急性疼痛の設定における完全なアゴニストオピオイドよりも,BUPの安全性と有効性の利点を探るためのさらなる研究が必要である.

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...

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...

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...

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy
170
Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...
