まとめ
胸脊髄麻酔は,帝王切開前の患者にとって,腰脊髄麻酔と比較して,低血圧と血管圧縮剤の必要性を減少させ,よりよい血液動力学的制御を提供します.
科学分野:
- 麻酔科
- 産婦人科
- クリティカル ケア 医療
背景:
- 妊娠前出血症は重度の妊娠合併症で 多臓器機能障害を引き起こし,しばしば帝王切開が必要になります.
- 帝王切開の腰椎麻酔は,交感性閉塞による著しい低血圧につながる可能性があります.
- 胸脊髄麻酔は,血液動力学的安定性を向上させるための代替手段として検討されている.
研究 の 目的:
- 乳房麻酔と腰椎麻酔の有効性,安全性,および血液動力学的効果を,帝王切開手術を受けた妊娠前患者で比較する.
- 血液動力学的安定性を評価する.
- 麻酔の成功,ブロックの特徴,有害事象,新生児のアウトカム,患者の満足度を含む二次的アウトカムを評価する.
主な方法:
- 緊急の帝王切開を受けた160人の患者を対象とした前向きな,オープンな,ランダム化制御試験です.
- 患者は胸脊髄麻酔または腰脊髄麻酔を受けた.
- 血液動力学的安定性,手術麻酔の成功,ブロックの持続時間,有害事象,新生児のアウトカムを分析した.
主要な成果:
- 胸脊髄麻酔は優れた血動力学的安定性を示し,低血圧率 (11. 68% 対 26. 31%) が著しく低下し,血管圧縮剤の使用が減少しました (p < 0. 001).
- 手術麻酔の成功率はグループごとに比較された (96. 67% vs 95%).
- 胸部麻酔は 感覚と運動の阻害期間を短くし 震えや吐き気も減り 患者の満足度も上がりました
結論:
- 胸脊髄麻酔は,先発性出産における優れた血液動力学的安定性と患者の快適性を提供します.
- 腰椎麻酔と同等の手術効果と新生児に対する安全性がある.
- 胸脊髄麻酔は,経験豊富な臨床医によって投与された場合,帝王切開の有効な選択肢です.

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 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: 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...
