まとめ
DIVEブロックは,チャイエンの技術と比較して,腰椎麻酔のより高い精度を提供し,同様の安全性と実用性があります. この対角ベクトルアプローチは,小腹筋に針を配置することを改善します.
科学分野:
- アナトミー
- 地域麻酔
- 医学教育
背景:
- 下肢の地域麻酔には 解剖学的な知識が不可欠です
- 超音波の誘導はますます使用されていますが,従来の画期的な技術は依然として有効です.
- 理論的には,チャイエンアプローチのような既存の方法よりも優位性があるように提案されています.
研究 の 目的:
- 腰椎間筋のブロックに対する DIVE 技術と Chayen のアプローチの臨床的適用性,正確性,およびリスクプロフィールを比較する.
- 各テクニックに関連した空間神経近似と合併症率を評価する.
主な方法:
- 腰椎間筋のブロックは,チャイエンの手法とDIVEの手法を用いて, 34人の埋葬された人体に双方向で行われました.
- ターゲットの領域は,大筋の後部の中央部分でした.
- 解剖学的地標が特定され,写真に撮られ,コンピュータ・アイド・メソッドを使って 穴の成功,神経の接近,および合併症を評価しました.
主要な成果:
- 両方のテクニックは,psoas筋肉を打つために同様の成功率を示しました (Chayen: 86.3%,DIVE: 82.8%).
- DIVEの穿刺は,psoasの筋肉の中央三分の一 (p<0. 001) の内側で顕著に位置していた.
- 血管や腎臓のパンクチャーのリスクは2つの方法 (p=0. 473とp=0. 367それぞれ) で比較可能であった.
結論:
- DIVEの方法は,チャイエンの手法と比較して,腰部筋のブロックに対するより高い穴の精度を提供します.
- DIVEブロックの実用性とリスクプロフィールはチャイエン技術と同等です.
- DIVEブロックの最適の穿刺標的は,後部上部椎から腰椎の脊椎プロセスまでの距離の4分の1から3分の1と推定されています.

Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia
560
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.

Spinal Nerves: Plexus I
1.3K
Nerve plexuses are networks of interlacing nerves that serve as communication hubs to distribute and organize nerve action across various body regions. The nerve plexuses are organized into the cervical plexus located in the neck region, brachial plexus in the shoulder area, lumbar plexus found in the lower back, sacral plexus situated in the pelvis, and coccygeal plexus located in the coccygeal region.

Local Anesthetics: Clinical Application as Spinal Anesthesia
777
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...

Local Anesthetics: Differential Sensitivity of Nerve Fibers
930
Local anesthetics (LAs) block the sodium channels of nerve trunks, sensory nerve endings, and neuromuscular junctions. Although LAs can block all kinds of nerves, the sensitivity of nerve fibers differs according to nerve types and structures. LAs are known to block myelinated fibers faster than unmyelinated ones. Also, they block pain or sensory neurons at low concentrations without affecting the motor neurons involved in muscle contractions. This helps relieve labor pain without affecting the...

Spinal Nerves: Plexus II
848
The plexuses of the lower body include the lumbar, sacral, and coccygeal plexuses, which innervate the abdomen, pelvis, legs, and coccygeal region. These plexuses control the transmission of sensory information and coordinate motor functions of the lower body.
The Lumbar Plexus
The lumbar plexus is situated within the lumbar region of the back and is primarily formed by the first four lumbar spinal nerves (L1 to L4). This plexus extends its branches into several nerves, including the...

Depolarizing Blockers: Pharmocokinetics
379
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...
