本文对37例重型颅脑损伤木后患者存活与死亡组的脑干听觉诱发电位(BAEP)参数进行比较,结果两组间Ⅰ—Ⅴ波的波间期(IPL)的差别有显著性。由此进一步探讨Ⅰ—ⅤIPL与死亡率及死亡患者平均存活天数的关系。作者认为,在判断重型颅脑损伤患者生命预后的诸项指标中,Ⅰ—ⅤIPL较为可靠,并提出若Ⅰ—ⅤIPL延长超过×5SD(4.92ms),患者伤后一周以上的存活可能性甚微。
In this paper, we compared the brainstem auditory evoked potentials (BAEP) parameters in survival and death in 37 patients with severe traumatic brain injury. The results showed that there was a significant difference in the wave interval (IPL) of Ⅰ-Ⅴ wave between the two groups. This further explores the relationship between I-ⅤIPL and mortality and death in patients with the average number of days. The author believes that in judging the prognosis of patients with severe brain injury in the indicators, Ⅰ-ⅤIPL more reliable and proposed if Ⅰ-ⅤIPL prolonged more than × 5SD (4.92ms), the patient survived more than a week after the survival of a very small probability .
