研究 の 目的:
- ALIF手術における手術前地域ブロックの安全性と有効性を体系的に検討する.
- 地域ブロックを投与された患者と投与されなかった患者の結果を比較する.
主な方法:
- MEDLINE,Embase,およびコクラン図書館の体系的な文献検索
- ランダム効果モデルを用いた4つの研究 (415人の患者) のメタ分析.
- 含有基準: ALIF患者,地域ブロック使用,年齢 ≥18,術後の痛みのスコア,およびオピオイドの要求.
主要な成果:
- 48 (MD - 0. 37) と72 (MD - 0. 76) 時間の術後におけるオピオイドの必要性を有意に減少させた.
- 24時間後に痛みのスコアが低下する傾向が見られたが,統計的に有意ではなかった.

Local Anesthetics: Clinical Application as Spinal Anesthesia
772
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: Clinical Application as Intravenous Regional Anesthesia
557
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.

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...

Local Anesthetics: Clinical Application as Surface, Infiltration, and Conduction Block Anesthesia
1.2K
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...

Local Anesthetics: Differential Sensitivity of Nerve Fibers
929
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...
