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.
目的 比較單純手法復位和手法復位合并口服抗眩暈藥治療良性陣發性位置性眩暈（BPPV）的短期和長期療效。 方法 將2004年1月－2011年6月期間收治的236例BPPV患者隨機分為兩組，對照組112例采用單純手法復位，觀察組124例在手法復位基礎上配合口服抗眩暈藥治療，兩組均于1周和3個月后復查，并隨訪觀察1年，且比較其療效。 結果 觀察隨訪1年后，對照組總治愈率92.86% (104/112），觀察組治愈率為93.54%（116/124），兩者比較差異無統計學意義。 結論 單純手法復位和手法復位合并口服抗眩暈藥治療BPPV其療效相當，但可作為BPPV患者的首選治療方法。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.
