持续调节喉膜袖口压力显著降低了腹腔镜胆囊切除术后的术后喉痛 (POST). 通过调节器在40cmH2O的压力下保持压力,降低了POST发生率和严重程度.
科学领域:
- 麻醉学 麻醉学
- 手术并发症 手术并发症
- 航空航道管理的管理.
背景情况:
- 手术后喉痛 (POST) 是全身麻醉后的一个常见并发症.
- 喉膜呼吸道 (LMAs) 经常被使用,袖口压力被怀疑是导致POST的因素.
- 优化LMA袖口压力可能会减少与呼吸道相关的不良事件.
研究的目的:
- 评估连续喉膜口罩气道袖口压力调节对POST的发生率和严重性的影响.
- 为了比较使用连续袖口压力调节器和不使用连续袖口压力调节器管理的患者之间的结果.
主要方法:
- 一项随机对照试验,涉及100名接受腹腔镜胆囊切除术的成年患者.
- 患者被分配到40cmH2O的连续袖口压力控制 (E组) 或标准LMA插入 (C组).
- 主要结局:POST发生率在输出管后24小时内. 二次结果:其他喉关不良事件.
主要成果:
- 连续调节组中POST的发生率明显较低 (10-12%) 与标准组相比 (32-36%) 在30分钟和24小时后的输出管 (P<0.05).
- 在持续调节组中,POST的严重程度和食障碍的发生率也显著降低 (P<0.05).

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...

Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
