概括
半遮蔽声道练习 (SOVTEs),包括阻流管 (FRT) 和莱萨克-麦森共振声疗法 (LMRVT),有效地改善了语音障碍指数得分. FRT证明与LMRVT不劣,在4周和8周的持续时间之间没有显著差异.
科学领域:
- 语音和听力科学 语言和听力科学
- 耳鼻喉科 耳鼻喉科 耳鼻喉科
- 康复医学 康复医学 康复医学
背景情况:
- 半遮蔽声道运动 (SOVTEs) 是针对声音障碍的标准治疗干预措施,旨在增加上呼吸道阻力.
- 两种突出的SOVTE协议,阻流管 (FRT) 和莱萨克-麦德森共振语音疗法 (LMRVT),被广泛使用.
研究的目的:
- 进行一项随机对照试验,比较FRT和LMRVT在声音障碍患者中的疗效.
- 对FRT与LMRVT进行非劣势分析.
- 调查治疗持续时间 (4 vs. 8 周) 对结局的影响.
主要方法:
- 67名患有语音障碍的参与者被随机分为五组:4周FRT,8周FRT,4周LMRVT,8周LMRVT和对照组.
- 语音障碍指数 (VHI) 和语音疲劳指数在治疗前和后被评估.
- 声学分析使用了声学语音质量指数;应用了线性回归和非劣等性测试.
主要成果:
- 与对照组相比,8周FRT和8周LMRVT都显著降低了VHI得分.
- 4周的FRT也显示了与对照组相比显著的VHI减少,而4周的LMRVT没有达到统计学意义.
- 发现FRT不低于LMRVT,使用VHI减少10个点的差距.
结论:
- 无论是FRT还是LMRVT都有效地改善了声音障碍患者的VHI分数.
- FRT是一种可行的LMRVT替代品,具有可比的疗效.
- 治疗持续时间为4周或8周,这两种方案的VHI得分都没有产生统计学上显著的差异.

Endoscopy is a non-surgical medical technique used to examine a person's internal organs and vessels. This lesson will focus on two types of endoscopic studies: bronchoscopy and thoracoscopy.
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...

Tracheostomy Suctioning II: Procedure
3.3K
Tracheostomy suctioning is a vital nursing procedure that involves removing secretions from the tracheostomy tube to maintain airway patency and prevent respiratory complications. Nurses need to understand the proper technique for tracheostomy suctioning to ensure patient safety and comfort. In this guide, we will outline the step-by-step process for performing tracheostomy suctioning, including preparing the sterile field, donning personal protective equipment (PPE), lubricating and connecting...

Suctioning the Oropharyngeal Airway
1.6K
In preparing for oropharyngeal airway suctioning, a nurse must gather all necessary equipment, including a suction unit with tubing, a prepackaged suction kit, sterile gloves, water or saline for irrigation, a water-soluble lubricant, and additional personal protective equipment (such as a gown, mask, and goggles) to control infections.
After assembling the equipment, the nurse should practice hand hygiene and don appropriate PPE according to infection control guidelines to avoid the...
