Injuries that result in a sudden increase in intra-abdominal pressure may cause a diaphragmatic tear and visceral herniation. Right-sided tears are significantly less likely than left-sided tears because of the protective effect of the liver. When diaphragmatic elevation persists in a post-trauma patient, or if unexplained acidosis or hypoxemia develops, herniation of abdominal contents should be suspected. This is particularly true when other signs of severe trauma are present, such as multiple rib fractures, laceration of the liver or spleen, or a history of deceleration injury.
导致腹内压突然升高的损伤可能会引起膈肌撕裂和内脏疝形成。由于肝脏的保护作用，右侧撕裂比左侧撕裂的可能性要小得多。当创伤后患者持续存在膈肌抬高，或者出现无法解释的酸中毒或低氧血症时，应怀疑有腹腔内容物疝出。当存在其他严重创伤的迹象时，如多根肋骨骨折、肝或脾撕裂伤或减速伤病史时，情况尤其如此。
