Methods A total of 54 patients diagnosed to have BPPV during June 2009 to June 2010 underwent bithermal caloric test and pure tone test before particle repositioning maneuver. Then, we analyzed the clinical features of the test results. Results The course of 40 patients with canal paresis (CP) was (4.25±2.75) weeks, which had a significant difference from the course of 14 patients with CP in the abnormal side, which was (9.21±5.85) weeks (t=4.235, Plt;0.05). Among the 39 patients with posterior semicircular canal benign paroxysmal positional vertigo (PSC-BPPV), 11 cases of canal paresis were found in the abnormal ear, and of the 15 patients with horizontal semicircular canal benign paroxysmal positional vertigo (HSC-BPPV), 3 cases of canal paresis were found. There was no statistical difference in the rate of canal paresis between the two groups of patients mentioned above (χ2=2.679,Pgt;0.05). Sixteen out of the 39 PSC-BPPV patients and seven out of the 15 HSC-BPPV patients had hearing loss (HL) in the abnormal ear with no statistical difference between the two groups of patients in the incidence of hearing loss (χ2=0.141,Pgt;0.05). Conclusion The incidence of CP and HL in the abnormal ear of patients with HSC-BPPV and PSC-BPPV is similar, and patients with long course of disease are more likely to have CP.
目的 探討兒童氣道異物的診斷、治療及并發(fā)癥發(fā)生的原因，以減少誤診及降低并發(fā)癥的發(fā)生率。 方法 回顧分析2009年1月－2010年8月經(jīng)病史、癥狀、體征及輔助檢查（胸部X線檢查或CT掃描）初診為氣道異物的317例患兒的臨床資料。所有患兒均行支氣管鏡檢查，明確有異物者行異物取出術(shù)，對術(shù)中、術(shù)后并發(fā)癥的原因和處理方法進(jìn)行總結(jié)。 結(jié)果 本組患者中有105例（33.1%）患兒曾被誤診為支氣管肺炎或其他呼吸系統(tǒng)疾病，經(jīng)支氣管鏡檢及異物取出術(shù)后，出現(xiàn)并發(fā)癥者共35例，包括：喉痙攣8例（22.8%），支氣管痙攣6例（17.1%），支氣管黏膜出血12 例（34.3%），皮下氣腫8例（22.8%），死亡1例（2.8%）。 結(jié)論 兒童氣道異物一經(jīng)確診或高度懷疑，應(yīng)盡快行支氣管鏡檢查，以保持呼吸道通暢。手術(shù)操作應(yīng)輕柔準(zhǔn)確，并注意觀察患兒全身狀況，是減少并發(fā)癥的關(guān)鍵。
