概括
在ERCP期间进行深度镇静时,双光谱指数 (BIS) 监测指导托的目标血度 (TPC). 肝硬化患者需要较低的TPC,恢复时间更长,突出了个性化镇静需求.
科学领域:
- 麻醉学 麻醉学
- 药理学 药理学是指药理学的学科.
- 胃肠病学 胃肠病学
背景情况:
- 对于内镜逆行性胆管松造影 (ERCP) 进行深度镇静,需要仔细定位麻醉剂.
- 普罗波是常用的,但其药理动力学可以改变肝硬化等肝病患者.
- 监测镇静的深度对于患者的安全和程序的成功至关重要.
研究的目的:
- 在ERCP期间评估双光谱指数 (BIS) 作为普罗波的目标血度 (TPC) 的指南.
- 为了比较propofol TPC,消费,恢复时间,以及肝硬化和没有肝硬化患者的不良事件.
- 评估TCI Marsh药理动力学模型的实用性,结合BIS监测以对个性化的普罗波镇静进行评估.
主要方法:
- 一项涉及42名肝硬化患者和43名接受ERCP的健康对照者的比较研究.
- 使用目标控制输液 (TCI) 系统 (沼泽模型) 给药普罗波,以达到60-70的BIS值.
- 患者在倾斜的位置自发呼吸;TPC和BIS在多个时间点记录,包括恢复.
主要成果:
- 与健康对照组相比,肝硬化患者需要显著降低普罗波TPC (例如,30分钟后2.7±0.5μg mL−1) 和消耗较少的普罗波 (270.4±6.9 mg) (3.3±0.4μg mL−1和390.8±13.4 mg).
- 肝硬化患者的康复时间延长了 (8.5±2分 vs 6.2±0.9分),尽管ERCP持续时间相似.
- 在肝硬化患者中观察到普罗波的累积效应,随着时间的推移,TPC显著下降.
结论:
- 在BIS指导下,TCI的普罗波 administration允许个性化的TPC,在肝硬化患者中显示出较低的需求.
- 这些研究结果表明,肝硬化改变了propofol的药理动力学,需要调整镇静策略.
- 深度镇静,自发呼吸的患者的倾斜姿势带有缺氧的风险,需要保持警.

Endoscopic Procedures V: ERCP
107
Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.

Esophageal Varices-II: Clinical Features and Management
46
Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.
