まとめ
胸間神経ブロック (ICNB) は,VATSのロベクトミー後の勃起器脊椎平面ブロック (ESPB) に比べて優れた早期の痛み緩和をもたらしました. 両方のブロックは安全で ICNBにより痛みの管理が容易になりました
科学分野:
- 胸部 外科
- 痛みの管理
- 地域麻酔
背景:
- ユニポータルビデオ支援胸腔切除手術 (VATS) では,手術後の痛みを効果的にコントロールする必要があります.
- 肋間神経ブロック (ICNB) と勃起器脊柱平面ブロック (ESPB) は,胸部手術の痛みに対して使用される地域麻酔技術である.
- VATSの後の鎮痛と回復を最適化することは 患者の成果にとって極めて重要です
研究 の 目的:
- 片口のVATS側切除術を受けた患者で,超音波による勃起器脊椎平面ブロック (ESPB) と胸腔間神経ブロック (ICNB) の鎮痛効果と安全性を比較する.
- 2つのブロック群の間の術後の痛みスコア,オピオイド消費,回復パラメータを評価する.
- ブロックに関連する有害事象の発生率を評価する.
主な方法:
- 選択的なユニポータルVATSロベクトミーを受けた60人の患者を対象としたダブルブラインド,ランダム化制御試験.
- 患者はランダムにICNB (n=30) またはESPB (n=30) に割り当てられました.
- 手術後の痛みは,静止状態と咳中の視覚アナログスケール (VAS) のスコアと,オピオイドの消費と回復の指標を用いて評価されました.
主要な成果:
- ICNBグループは,手術後の4時間と8時間に,ESPBグループと比較して,休息と咳のVASスコアを大幅に低下させました.
- ESPBを投与された患者は,より早くモルヒネを必要とし,24時間の累積摂取量が高かったが,この違いは統計的に有意ではなかった.
- 術後の吐き気,嘔吐,合併症,排水期間,または入院期間において,グループ間で有意な差異は認められなかった.
結論:
- ICNBは,ユニポータルVATSロベクトミー後のESPBと比較して,早期の鎮痛効果が優れている.
- ICNBとESPBはどちらも安全で,ユニポータルVATSロベクトミー後の迅速な回復を促進します.
- ICNBは,この患者集団における早期の術後の疼痛管理に好ましい選択である可能性があります.

Nondepolarizing (Competitive) Neuromuscular Blockers: Pharmacological Actions
525
Nondepolarizing neuromuscular blockers prevent the membrane depolarization of muscle cells and inhibit muscle contraction. These are usually administered with anesthetics to achieve complete muscle relaxation. Upon administration, these drugs first block the small, rapidly contracting muscles of the face and hands, followed by the larger muscles of the trunk and the intercostal muscles. The diaphragm is the last muscle to be affected.

Endoscopic Studies II: Thoracocentesis
493
Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...

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.

Nondepolarizing (Competitive) Neuromuscular Blockers: Mechanism of Action
2.1K
Nondepolarizing neuromuscular blockers induce paralysis by competitively blocking nicotinic acetylcholine receptors at the muscle end plate. Examples include pancuronium, mivacurium, vecuronium, and rocuronium. These quaternary ammonium derivatives are administered intravenously, are poorly absorbed, and are excreted via the kidneys.
Competitive antagonists prevent acetylcholine from binding to its receptor, inhibiting membrane depolarization. Without conformational changes or intrinsic...

Endoscopic Studies I: Bronchoscopy and Thoracoscopy
269
Endoscopy is a non-surgical medical technique used to examine a person's internal organs and vessels. This lesson will focus on two types of endoscopic studies: bronchoscopy and thoracoscopy.
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...

Skeletal Muscle Relaxants: Therapeutic Uses
612
Skeletal muscle relaxants are used to relax muscle tone and alleviate painful muscle contractions. However, the choice of skeletal muscle relaxants depends on the duration of the surgical procedure in order to minimize potential side effects. Skeletal muscle relaxants like neuromuscular blocking agents [NMBAs] are commonly employed as adjuvants alongside general anesthetics in clinical settings. NMBAs are also used to maintain controlled ventilation during surgery of the larynx or pharynx...
