[物理治療師] 心肺疾病與小兒疾病物理治療學
第 14 題
在新生兒加護病房，為預防早產兒發生呼吸暫停（apnea），下列何種頸部的擺位最佳？
- A 屈曲
- B 旋轉向右（rotation to right）
- C 旋轉向左（rotation to left）
- D 稍微後仰（slightly extended）
思路引導 VIP
從新生兒解剖生理學的角度思考，早產兒的氣管支撐組織尚未發育成熟且管徑極為狹小。請評估，若頸部處於過度屈曲（Flexion）或極端伸展狀態時，對氣道通暢度 ($Airway Patency$) 與呼吸阻力 ($Resistance$) 會產生何種物理性影響？為了維持氣道軸線成一直線並避免柔軟的氣管塌陷，哪一種微調的擺位最能模擬生理上的「嗅探姿勢」以確保呼吸順暢？

Well, look at you. You actually got it right.
- Fundamental Principle Check: One would hope that by now, you understand the delicate nature of a premature infant's airway. Narrow trachea, flimsy cartilage – any egregious flexion or absurd extension will, predictably, lead to collapse. The choice of (D) Slightly extended – or as we clinicians call it, the "sniffing position" – is hardly rocket science. It's the most basic way to achieve optimal oral-pharyngeal-laryngeal alignment, ensuring Airway Patency. This isn't groundbreaking; it's just preventing a very preventable obstruction.
