目的 比较单纯手法复位和手法复位合并口服抗眩晕药治疗良性阵发性位置性眩晕（BPPV）的短期和长期疗效。 方法 将2004年1月－2011年6月期间收治的236例BPPV患者随机分为两组，对照组112例采用单纯手法复位，观察组124例在手法复位基础上配合口服抗眩晕药治疗，两组均于1周和3个月后复查，并随访观察1年，且比较其疗效。 结果 观察随访1年后，对照组总治愈率92.86% (104/112），观察组治愈率为93.54%（116/124），两者比较差异无统计学意义。 结论 单纯手法复位和手法复位合并口服抗眩晕药治疗BPPV其疗效相当，但可作为BPPV患者的首选治疗方法。Objective To evaluate the short-term and long-term effect of canalith repositioning procedures with or without anti-vertigo drugs on benign paroxysmal positional vertigo (BPPV). Methods A total of 236 cases of BPPV that were treated with particle repositioning maneuver with medicine treatment from January 2004 to June 2011. The patients were divided into control group (112 patients, underwent canalith repositioning procedures) and observation group (124 patients, underwent canalith repositioning procedures with medication of anti-vertigo drugs). The two groups were reappraised after one week and three months respectively, and the follow-up duration was one year. Results The success rate was 92.86% (104/112) in the control group and 93.55%(116/124) in the observation group one year after the treatment. The difference between the two groups was not significant. Conclusion The effect of canalith repositioning procedures with or without anti-vertigo drugs on BPPV does not differ much from each other.
ObjectiveTo explore the reasonable path of caloric test in videonystagmography examination. MethodsPatients who received the videonystagmography examination in Xi'an Central Hospital were retrospectively analyzed. Using caloric test as standard, sensitivity, false negative rate, specificity and false positive rate of single temperature test were calculated and compared. Data was analyzed using SPSS 13.0 software. ResultsA total of 263 patients were included. In all subjects, the sensitivity of single hot test was 81.7%, which was higher than single cold one. The false negative rate was 18.3%, which was lower than single cold one. There were significant differences in the rate between both methods (P < 0.05). In patients accompanied with spontaneous nystagmus, the sensitivity of single hot test was 90.8%, which was the highest; the false negative rate was 9.2%, which was the lowest. There were significant differences in the rate between both methods (P < 0.05). ConclusionCold or warm water (gas) perfusion could be conducted in the reasonable path of caloric test as follows: heat stimulation of the affected side, heat stimulation of the normal side, cold stimulation of the affected side, and cold stimulation of the normal side. If the patients are unable to tolerate caloric test, the results of single hot test could be used as reference.
