まとめ

カタラクタ手術中の痛みを軽く軽減します. この痛みを和らげる効果は近視の患者で最も顕著です.

科学分野:

眼科について
外科麻酔
臨床試験

背景:

白内障の手術は一般的だ.
白内障手術中の痛みの管理は患者の快適さにとって極めて重要です
内腔麻酔は痛みをコントロールする選択肢です.

研究の目的:

常規の白内障手術中の痛みを軽減する内腔リドカインの有効性を評価する.
室内リドカインと対照溶液を投与した患者の痛みレベルを比較する.
手術中の痛みの感受に影響を及ぼす患者の要因を特定する.

主な方法:

予見性,単盲,ランダム化制御試験が行われました.
ファコエムルシフィケーションによる白内障抽出手術を受けた成人患者は,室内リドカインまたはバランス塩溶液のいずれかをランダムに投与された.
痛みは,注射と手術の完了の2つの重要な時間点で0から10のスケールで評価されました.

主要な成果:

リドカイン群は,対照群 (0. 72/ 10) と比較して,全体的な痛みのスコアが有意に低かったと報告した.
近視が少ない患者 (0. 50/10) よりも近視が強い患者 (1. 80/10) が痛みを感じました.
注射時の痛みの有意な差も,手術後の視力の有意な差も観察されなかった.

結論:

静脈内リドカインは,白内障手術中の痛みを統計的に有意に軽減しますが,控えめです.
室内リドカインの鎮痛作用は近視患者においてより顕著である.
患者の快適さを高めるために,室内麻酔の最適化については,さらなる研究が行われる可能性がある.

Local Anesthetics: Common Agents and Their Applications

544

Local anesthetics (LAs) are commonly used for various applications in medical and dental procedures. Some of the common agents used are cocaine, lidocaine, and bupivacaine.
Cocaine is an ester of benzoic acid and methylecgogine. It is used to anesthetize and vasoconstrict locally. Currently, it is used primarily for topical applications. It is beneficial for surgeries on the upper respiratory tract, providing anesthesia and shrinking the mucosa. Cocaine in the form of cocaine hydrochloride is...

Local Anesthetics: Clinical Application as Spinal Anesthesia

771

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: Pharmacokinetics

847

The potency and duration of action of local anesthetics (LAs) are determined by their pharmacokinetics. Pharmacokinetics describes how LAs are absorbed, distributed, metabolized, and eliminated from the body. When administered to the vascular tissues, LAs are quickly absorbed and enter the systemic circulation, reducing their localized effects. Adding vasoconstrictors such as epinephrine to LAs reduces their absorption into the systemic circulation, making them clinically effective. The...

Local Anesthetics: Clinical Application as Epidural Anesthesia

497

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...

Angle Closure Glaucoma: Treatment

665

Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

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.
One of the advantages of...
