口腔頜面部外傷時為什麽要特別注意呼吸道是否

  

口腔頜面部外傷時為什麽要特別注意呼吸道是否通暢?若出現窒息,如何緊急搶救

  口腔頜面部外傷時為什麽要特別注意呼吸道是否通暢?若出現窒息,如何緊急搶救,口腔颌面部是呼吸道上端所在部位,當外傷時,可因多種情況引起呼吸道通氣受阻,氧氣吸入不足而導致窒息。如口底、咽旁及舌根等部位受傷後,可因水腫的壓迫而影響呼吸道通暢。下颌骨正中部位骨折後可導致舌後墜使咽腔縮小,影響呼吸道通暢。昏迷傷員口內的分泌物、血凝塊及異物集聚在口咽部,容易發生吸入性窒息。對于口腔颌面部外傷患者,當出現煩躁不安、面色蒼白、鼻翼扇動、口唇發绀、瞳孔散大等呼吸困難症狀時,則應爭分奪秒進行搶救。可調整患者體位,取側臥位或仰臥位,使頭偏向一側,以利于口內分泌物流出;可將患者頭後仰,托起下颌,若有舌後墜,應同時將舌牽出口外,保持呼吸道通暢;可用手指掏出口內血凝塊等阻堵物或用吸引器吸出口內分泌物或血液,然後緊急送往醫院搶救。
