What symptoms are easily caused by severe crush injury.

summary

Speaking of severe crush injury, you should not feel very strange, Middle ear barotrauma especially needs to be differentiated from other ear diseases, such as otitis media. In any case, we need to understand it. The most common symptoms of otitis media are stuffy feeling or blocking feeling in the ear, hearing loss and tinnitus. It often occurs after a cold or unconsciously. Sometimes the head position change can improve the hearing, and enhance the self hearing. Some patients have mild earache, and children have a headache It is often manifested as slow obedience or inattention. Under normal circumstances, the eustachian tube is opened instantaneously during swallowing, yawning and blowing nose to keep the pressure in the tympanic chamber in balance with that outside. Severe crush injury patients easy to cause what symptoms to tell you.

What symptoms are easily caused by severe crush injury.

First: the main clinical symptoms of middle ear barotrauma are that the negative pressure in tympanic cavity can cause the blood vessel dilation of submucosal tissue, resulting in the leakage of serum, and even bleeding, forming middle ear effusion or hematocele. With the aggravation of negative pressure in middle ear, the tympanic membrane itself can appear invagination, blood filling, peeling off of mucous membrane layer and fibrous layer, and even perforation. Therefore, it shows sudden sensation, ear tightness, tinnitus, headache Pain, dizziness and other symptoms.

Second: when the patient appears, for example, when taking a plane, the lower the distance from the ground, the faster the descent speed is, which will lead to a larger pressure difference in a short time. If there is no active ventilation action, the middle ear barotrauma is prone to occur. Or when diving, the tympanic membrane may rupture because the eustachian tube can not be blown to restore the balance between middle ear pressure and external pressure.

Third: Patients with mild symptoms can only feel ear tightness occasionally, which can be recovered after a few hours. However, patients with severe symptoms may have earache, tinnitus and obvious decrease of suction, which can be recovered after a few days. In some severe cases, the whole tympanic membrane can be congested, and perforation of tympanic membrane occasionally occurs.
