(耳)[医] 气压伤
Sinus and middle ear barotrauma are the most common dive-related injuries.
鼻窦和中耳的气压性创伤是最常见的和潜水相关的创伤。
In your case, a similar episode of barotrauma could lead to further damage and additional impairment.
对于你的情况,气压性创伤会导致更多的伤害。
Objective To investigate the cerebral imaging changes of pulmonary barotrauma in compressed air divers.
目的探讨空气潜水所致肺气压伤患者脑影像学改变。
Methods MRI and CT imaging of brain were examined and analysed on 5 cases of pulmonary barotrauma complicated with cerebral arterial gas embolism.
方法对5例空气潜水所致肺气压伤并发脑动脉气栓症患者进行了脑部mri检查或脑部CT检查,分析脑动脉气栓所致脑影像学的变化。
When barotrauma has occurred in the middle ear, it is not unusual for the diver to have a sensation of pressure or fullness and decreased hearing.
当中耳受到气压性创伤的时候,潜水者会经常有压力、塞和听力下降的感觉。
气压伤(Barotrauma)是指人体内充满空气的空腔器官(如中耳、鼻窦、肺等)因外界环境压力急剧变化,导致腔内气压与外界无法平衡而引起的组织损伤。其核心机制是气体体积随压力变化(波义耳定律),当空腔与外界压力差过大且无法通过咽鼓管等通道及时调节时,就会造成组织牵拉、出血甚至破裂。
常见类型与机制:
高危场景与预防: 气压伤易发生于潜水(尤其深潜与上升)、航空飞行(起飞降落)、高压氧治疗、机械通气等场景。预防关键在于平衡压力:潜水时需缓慢下潜/上升并做耳压平衡动作(如捏鼻鼓气);感冒或鼻窦炎患者应避免潜水或飞行;机械通气需精细控制压力参数。梅奥诊所强调,掌握正确的压力平衡技巧和识别早期症状是避免严重损伤的关键 。
