まとめ
オピオイドを節約する麻酔 (OSA) は,腹腔鏡用スリーブ胃切除術 (LSG) の後の吐き気と嘔吐 (PONV) を著しく軽減します. このアプローチは,PONVの発生率を下げることで,患者のアウトカムを改善しながら,比較可能な痛み緩和と回復を提供します.
科学分野:
- 麻酔科
- 胃腸内科
- 腹部 外科
背景:
- 術後の吐き気と嘔吐 (PONV) は,腹腔鏡外胃切除術 (LSG) の後の一般的な合併症である.
- 手術中のオピオイド投与は,LSG患者におけるPONVの高い発生率に大きく寄与する要因である.
研究 の 目的:
- エスケタミンベースのオピオイド保存麻酔 (OSA) と伝統的なオピオイドベースの麻酔の効果を比較して,LSG後のPONVを減少させる.
- 手術後の痛み管理と回復に対するOSAの影響を評価する.
主な方法:
- 予見性,ダブルブラインド,ランダム化制御試験が行われました.
- LSGを受けた成人患者は,OSAまたはオピオイドベースの麻酔グループに割り当てられました.
- 主な評価対象は,手術後48時間のPONVの発生率でした.
主要な成果:
- OSAは,オピオイドベースの麻酔と比較して,手術後の48時間以内にPONVの全体的な発生率の有意な減少を示しました.
- 最初の24時間以内にPONVの臨床的に有意な減少が観察されました.
- PONVの重症度は,OSA群で6~24時間の術後期に顕著に減少した.
- 鎮痛効果と術後の回復は,2つの麻酔アプローチの間で比較可能でした.
結論:
- エスケタミンを用いたオピオイド緩解麻酔 (OSA) は,LSGを受けた患者のPONVを緩和するための効果的な戦略です.
- OSAは,LSGにおける麻酔管理に価値のある代替手段を提供し,患者の快適さを向上させ,痛みコントロールを損なうことなくPONVの負担を軽減します.

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy
170
Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...

Parenteral Anesthetics: Overview
196
Intravenous anesthetics are drugs administered parenterally to induce anesthesia or sedation. Propofol is a widely used agent formulated as a 1% emulsion in soybean oil, glycerol, and egg phosphatide. It induces rapid anesthesia primarily due to its rapid distribution from the bloodstream to target tissues and is metabolized in the liver. However, it can cause significant pain on injection and hypertriglyceridemia. Fospropofol, a water-based prodrug of propofol, lacks these adverse effects.

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...

General Anesthesia: Overview
283
Anesthesia is a medical procedure that uses drugs for CNS suppression to enable painless surgeries and procedures. The selection of anesthetics is influenced by their pharmacokinetic properties, side effects, and patient characteristics. Various types of anesthesia include general, local, regional, spinal, and inhalational.
General anesthesia induces unconsciousness in the whole body, while the others target specific areas or sensations. It is administered to minimize adverse effects, maintain...

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...

Stages of General Anesthesia
681
Various sedation levels offer significant advantages in facilitating procedural interventions for patients undergoing medical or invasive surgical procedures. These levels span from anxiolysis to general anesthesia, providing a spectrum of sedative effects to cater to specific patient needs. Anxiolysis reduces anxiety and is achieved through minimal sedation, enabling patients to remain awake and responsive while feeling more at ease during the procedure. This level can benefit minor...
