Correlation between the changes of fibrinogen and the treatment effect of all-frequency sudden deafness / 中华耳鼻咽喉头颈外科杂志

ABSTRACT

Objective@#To analyze the correlation between the changes of fibrinogen and the treatment effect of all-frequency sudden deafness, and to explore the individualized treatment strategy for the use of Batroxobin.@*Methods@#Patients with all-frequency sudden deafness who were admitted to Department of Otorhinolaryngology, People′s Hospital of Peking University, from January 2010 to September 2016 were selected. All patients were given standard treatment and regular use of Batroxobin. Value of fibrinogen on D1 (before treatment) / D3 / D7 (±1) and D14 (±2) were recorded, at the same time, the correlation between the changes of fibrinogen and prognosis of all-frequency sudden deafness by the audiograms of onset and after-treatment of all patients were analyzed. Independent t-test was used to analyze normal distributed measurement data and chi square linear trend test was used to analyze the curative effect of different fibrinogen groups.@*Results@#A total of 148 patients were included, the outcomes were worst when the patient′s fibrinogen was below 2 g/L or above 4 g/L before treatment, ineffective rate were both 50%. The fibrinogen was lowest when the treatment came to the third day. Normally, the patient′s prognosis was best when this value waved between 0.7 and 0.9 g/L, with a total effective rate between 73.9% and 83.3%. The fibrinogen value of the 7th day was a good indicator of the outcome, and Fib7 value was significant lower in patients of effective group than ineffective ones ((1.25±0.37)g/L vs (1.38±0.35) g/L, t=-0.27, P=0.04). Patients found a best recovery when Fib7 was below 1 g/L, and the higher the Fib7 value, the higher the inefficiency (χ2=7.55, P=0.01). Batroxobin showed safety during the treatment and found no complications.@*Conclusion@#The change of fibrinogen in the process of all-frequency sudden deafness is closely related to the curative effect.
