有人报导用六氟化硫(SF_6)气体代替空气作人工气腹,能保持6周时间。作者等曾用以治疗鼻咽癌继发浆液性中耳炎,结果获得听力持续改善。因此作者们决定将 SF_6试用于儿童浆液性中耳炎。选择5例年龄4～8岁患儿,均有持续2个多月的双侧浆液性中耳炎病史,两侧气骨导差距大致相等,为30dB。手术在全麻下进行(不用笑气)。选气骨导差距较大的一侧耳,先于鼓膜上涂一层微薄的可塑性火棉胶,2～3
It was reported that sulfur hexafluoride (SF_6) gas instead of air for artificial pneumoperitoneum, to maintain for 6 weeks. The authors have used to treat secondary nasopharyngeal otitis media, resulting in continuous improvement of hearing. Therefore, the authors decided to try SF_6 in children with serous otitis media. Five children aged 4 to 8 years old were selected, both of which had a history of bilateral serous otitis media for more than 2 months. The difference of the air-bone conduction between the two sides was approximately equal to 30 dB. Surgery under general anesthesia (no laughter). Select the gap between the larger side of the air-side of the ear, first in the tympanic membrane coated with a layer of plasticity collodion, 2 ~ 3
