概括
在成长中的II类患者中,Herbst用牙或骨固定装置改善了口腔气道尺寸. 骨固定显示气道体积和长度的增加更大,这表明了潜在的形态适应.
科学领域:
- ортодонтика和牙科研究.
- 空气道形态和生长
- 头骨面部的发展
背景情况:
- 第2类第1部分缺陷通常呈现于狭窄的口腔大气道.
- 赫伯特设备用于纠正生长期间的II类缺陷.
- 牙 (HDA) 和骨 (HSA) 固定之间的选择可能会影响气道变化.
研究的目的:
- 为了比较赫伯斯特用牙固定 (HDA) 与骨固定 (HSA) 对口腔大气道尺寸的影响.
- 为了评估口腔大气道体积,长度和横截面积的变化,在成长中的II类第1部分恶性闭塞患者中.
主要方法:
- 随机对照试验涉及40名患有II类第1部分缺陷的成长期患者.
- 患者被随机分配,在青春期成长的高峰期接受HDA或HSA12个月.
- 使用圆束计算断层扫描 (CBCT) 评估了口腔气道尺寸.
主要成果:
- 无论是HDA和HSA组都显示出口腔气道尺寸的显著改善.
- 与牙固定 (HDA) 组相比,骨固定 (HSA) 组的平均气道体积,长度和横截面积显著增加.
- 集团内部分析显示,HDA集团的最小轴面积显著改善.
结论:
- 赫伯斯特两款配有牙和骨 anchorage 的设备都有效地增加了成长中的II类患者的口腔大气道尺寸.
- 骨的固定导致了更明显的维度变化,表明了潜在的形态适应.
- 需要进行进一步的长期研究,以确定这些气道变化对呼吸功能的临床意义.

Cardiopulmonary Resuscitation II: ACLS Airway Management
487
Airway management is a key skill in emergency and critical care settings, as maintaining a clear airway is essential for adequate oxygenation and ventilation.Head Tilt-Chin Lift TechniqueThe head tilt-chin lift maneuver is an essential technique primarily used in patients without suspected cervical spine injuries. To perform this maneuver, one hand is placed on the patient’s forehead, and gentle pressure is applied backward to tilt the head. The fingertips of the other hand are positioned...

Suctioning the Oropharyngeal Airway
749
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...
