概括
在III类骨高角度缺陷中,下偏差缩小了上呼吸道. 整形外科手术可以部分恢复呼吸道空间,但对于患有先前存在的狭窄呼吸道的患者来说,仔细规划至关重要.
科学领域:
- 牙科 牙科是指牙科的专业.
- 矯正牙科 矯正牙科是一種矯正牙科.
- 手术解剖学手术解剖学
背景情况:
- 骨III类缺陷通常涉及下回退,可以与或没有下偏差.
- 高角缺陷与特定的面形态有关,这些形态可能会影响气道尺寸.
- 下偏差对上呼吸道形态的影响和手术纠正的影响仍然是临床兴趣的领域.
研究的目的:
- 为了比较 III 类骨高角缺陷症患者的上呼吸道尺寸,包括下偏差和没有下偏差.
- 为了评估整形手术对这些患者群体上呼吸道空间的影响.
主要方法:
- 对15名患有骨III级高角缺陷和下偏差的患者的圆束计算机断层扫描 (CBCT) 扫描和15名没有偏差的对照者的比较分析.
- 在16名患有偏差的患者和13名没有偏差的患者中,对经过整形手术后的上呼吸道变化的评估.
主要成果:
- 患有下偏差的患者表现出明显较小的口腔大和下斜直径,横截面积,体积和上空气道总体体积.
- 经过orthognathic手术后,偏差组显示了口腔大的斜腰直径的增加,而非偏差组显示了下降.
- 在手术后的非偏差组中,口腔大和下的横截面积和体积的减少更为明显.
结论:
- 骨III类高角度缺陷的下偏差与较窄的下呼吸道有关.
- 对下偏差的整形手术可以部分补偿外科手术诱导的气道狭窄.
- 术前的气道评估对于手术规划至关重要,特别是在先前存在狭窄气道的情况下,这表明双手术或减少下逆转的潜在益处.

Suctioning the Oropharyngeal Airway
172
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...

Oxygen Delivering System III: Tracheostomy and T-piece
393
Oxygen delivery is critical in clinical care, especially for patients with respiratory disorders or those undergoing surgical procedures. Various systems, such as tracheostomy and the T-piece, deliver oxygen to the lungs, ensuring adequate arterial oxygenation.
Tracheostomy
A tracheostomy is a surgically created opening (stoma) in the anterior part of the trachea. It is used to establish a patient airway, bypass an upper airway obstruction, simplify the removal of secretions, permit long-term...

Suctioning the Nasopharyngeal Airway
257
Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.
