Zuck和Bergin发现手术前凝血酶生成指数(Thrombmgeneration index)(TGI)平均值偏高者,术后发生合并症之数明显增高;Von Kaulla和Von Kaulla发现手术前抗血清凝血酶|||(Serum antithrombin|||)(SAT |||)值偏低者,手术后发生合并症之数亦明显增高。本文收集14例几小时内或几天内突然发作的感觉神经性聋患者,观察其血液凝固机制。另选50名正常人和4名由于其他原因发生耳聋的患者作对照。14例的听力损失为单侧、不伴眩晕,发病前患者 Zuck and Bergin found that those with higher mean Thrombomotion Index (TGI) before surgery had a significantly higher postoperative comorbidity; Von Kaulla and Von Kaulla found that preoperative serum antithrombin ||| (Serum antithrombin |||) (SAT |||) value is low, the number of complications after surgery was also significantly higher. This article collected 14 cases within a few hours or a few days of sudden onset of sensory deafness in patients with blood coagulation mechanism. Another 50 normal subjects and 4 patients with deafness for other reasons were selected as controls. The hearing loss in 14 patients was unilateral without dizziness and before onset
