概括
使用电阻断层扫描 (EIT) 进行个性化正极端呼气压 (PEEP) 定位,显著降低了腹腔镜手术的儿童手术后的骨质疏通. 与固定PEEP相比,这种肺部防护通风策略改善了结果.
科学领域:
- 麻醉学和外科手术期间的医学.
- 儿科重症监护 儿科重症监护
- 呼吸系统生理学 呼吸系统生理学
背景情况:
- 手术后的骨质疏松症是儿科患者的常见并发症,特别是在腹腔镜手术期间.
- 虽然积极的末端呼气压 (PEEP) 已被认为具有肺部保护的好处,但最佳的PEEP水平用于预防脱氧酶仍然存在争议.
- 电阻断层扫描 (EIT) 提供了一种实时,个性化的肺通风监测方法.
研究的目的:
- 调查由EIT指导的个性化PEEP定位是否可以降低儿童手术后骨质疏松症的发生率和严重程度.
- 在儿科腹腔镜手术患者中,比较EIT导向PEEP与固定PEEP策略的疗效.
主要方法:
- 一项随机对照试验,涉及50名儿童 (2-7岁) 接受腹腔镜修复.
- 两组:对照组接受了5mmHg的固定PEEP;实验组接受了由EIT定位的个性化PEEP.
- 在多个时间点 (输入管后,外科手术后,输出管后) 使用肺超声波 (巩固和B线分数) 评估的肺.
主要成果:
- 与对照组 (92%) (P=0.037) 相比,在EIT组中,手术后骨质疏松症的发生率明显较低 (64%).
- 在EIT组 (48%) 和对照组 (80%) (P=0.038) 中,输出管术后1小时的甲基发生率也减少了 (P=0.038).
- EIT组在手术后和输出管后显示出明显较低的肺结合和B线分数,并在输出管后经历了较少的脱度.
结论:
- 以EIT为指导的个性化PEEP定位是一种有效的策略,可以减少儿科腹腔镜外科手术中手术后骨质疏松症的发生率和严重程度.
- 这种方法增强了肺部的保护,并可能改善儿科手术患者的呼吸结果.

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy
178
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...

Endoscopic Studies II: Thoracocentesis
519
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...
