Hyperbaric oxygen treatment is associated with an increased risk of barotrauma to the tympanic membrane and middle ear. An artificial airway may compromise normal eustachian tube function and equilibration of middle ear pressures. This retrospective study was designed to evaluate the risk of middle ear complications in 267 patients receiving hyperbaric oxygen (HBO) therapy and to compare those with and without artificial airways. Charts of all patients were reviewed for middle ear and tympanic membrane complications and myringotomy tube placement. Eighteen of the 267 patients had artificial airways. Seventeen (94%) of these 18 patients developed middle ear or tympanic membrane complications, and 11 (61%) required tympanostomy tubes for pain, hemotympanum, or serous otitis. In contrast, 114 (45.8%) of the 249 patients without airways developed ear complications, and 53 (21.3%) required tympanostomy tubes. These results suggest that patients with an artificial airway who are receiving HBO therapy are at greater risk for developing tympanic membrane and middle ear complications than nonintubated patients. Similarly, patients with artificial airways receiving HBO frequently require placement of tympanostomy tubes.
高压氧治疗与鼓膜和中耳气压伤风险增加相关。人工气道可能会损害咽鼓管的正常功能以及中耳压力的平衡。本回顾性研究旨在评估267例接受高压氧（HBO）治疗的患者发生中耳并发症的风险，并比较有和没有人工气道的患者。对所有患者的病历进行了回顾，以了解中耳和鼓膜并发症以及鼓膜切开置管情况。267例患者中有18例有人工气道。这18例患者中有17例（94%）出现了中耳或鼓膜并发症，11例（61%）因疼痛、血鼓室或浆液性中耳炎需要鼓膜造孔置管。相比之下，249例没有气道的患者中有114例（45.8%）出现耳部并发症，53例（21.3%）需要鼓膜造孔置管。这些结果表明，接受HBO治疗且有人工气道的患者发生鼓膜和中耳并发症的风险高于未插管患者。同样，接受HBO治疗且有人工气道的患者经常需要进行鼓膜造孔置管。
