まとめ
手根管解放術の症例において、リドカインの代替としてロピバカインを使用したビアブロック麻酔が安全に投与されました。患者は有害事象を経験せず、この静脈内地域麻酔技術の安全性が実証されました。
科学分野:
- 麻酔科学
- 地域麻酔
- 疼痛管理
背景:
- ビアブロックは、静脈内地域麻酔の安全かつ効果的な方法です。
- 通常、リドカインのような希釈された短時間作用型局所麻酔薬を使用します。
- 正しく行われれば合併症はまれであり、無血の手術野と鎮痛を提供します。
研究 の 目的:
- ビアブロック中にリドカインの代わりにロピバカインが誤って投与された症例を報告すること。
- 標準的な実践からの逸脱後の安全性と患者の転帰を評価すること。
主な方法:
- 41歳の女性が内視鏡下手根管解放術を受けました。
- ビアブロックが実施されましたが、0.5%リドカインの代わりに0.5%ロピバカイン30mLが誤って使用されました。
- 総止血帯時間は46分でした。
主要な成果:
- ロピバカインの意図しない投与にもかかわらず、患者は神経学的または心血管系の症状を示しませんでした。
- 脂質エマルジョンが予防的に投与されました。
- 患者は合併症なく同日退院しました。
結論:
- この症例は、0.5%ロピバカインを用いたビアブロックが、意図しない投与であっても安全である可能性を示唆しています。

Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia
1.1K
Intravenous regional anesthesia or the Bier block technique is used to anesthetize a specific limb or extremity. It uses exsanguinated or blood-drained vessels to transport local anesthetics or LAs to the peripheral nerve trunks. Lidocaine without vasoconstrictors like epinephrine is most commonly used for this technique. Other drugs used are prilocaine, ropivacaine, and chloroprocaine. Bupivacaine is not recommended for this technique due to its high cardiac toxicity.

Depolarizing Blockers: Pharmocokinetics
547
Depolarizing blockers are administered through intravenous injection. Succinylcholine is the most common choice of depolarizing blockers in emergency clinical practices. Although they have a rapid onset, they readily diffuse away from the motor end plate into the extracellular fluid. They are metabolized by enzymes such as liver butyrylcholinesterase and plasma pseudocholinesterases. This produces a short duration of action, typically 5-10 minutes long, unlike nondepolarizing blockers, which...

Local Anesthetics: Clinical Application as Surface, Infiltration, and Conduction Block Anesthesia
1.8K
Depending on the target organ, local anesthetics (LAs) can be administered via various routes. In surface anesthesia, LAs are applied directly to the surface of the skin or mucous membranes. It is widely used for topical skin numbing before venipuncture or minor surgical procedures. Commonly used surface local anesthetics are lidocaine or benzocaine sprays or creams. Surface anesthesia occurs within 5 minutes and lasts for about 60 minutes. One of the main disadvantages of topical anesthesia is...

Parenteral Anesthetics: Overview
540
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.

Local Anesthetics: Clinical Application as Epidural Anesthesia
661
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...

Local Anesthetics: Clinical Application as Spinal Anesthesia
1.3K
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...
