Objective To find new way to reduce non-recurrent laryngeal nerve (NRLN) injuries by applying intraoperative neuromonitoring(IONM) to identify NRLN in thyroidectomy. Methods Records of 279 patients who underwent complex thyroidectomy by applying IONM to identify and monitor RLN from Mar. 2009 to Jan. 2010 were veviewed. We proposed the skills to identify and monitor NRLN and predict RLN varition through exploring vagus nerve and RLN before RLN dissection. Results 6 cases NRLN located on the right side were all accurately identified by IONM, thus no injury of NRLN occurred during thyroid operations. Conclusions NRLN is difficult to be predicted preoperatively and identified by naked eyes. The application of IONM to predict, identify and monitor NRLN could remarkably reduce the possibility of NRLN injury.

ObjectiveTo investigate the mechanism and prevention of invisible injury of recurrent laryngeal nerve (RLN) system in thyroid surgery, with the application of intraoperative neuromonitoring ( IONM ) system. MethodsThe type of invisible RLN injury and its protection with the application of IONM system were analyzed. ResultsThe causes of invisible RLN injury mainly included stretching of Berry ligament or the tumor,contusion, thermal injury, cutting of silk and suction injury. RLN invisible injury was recoverable through neurotrophic and symptomatic treatment. No permanent vocal cord paralysis occurred. ConclusionsWith the application of IONM system, some invisible type of RLN injuries can be found. The risk of RLN injury can be reduced if the surgical techniques are improved with the development of study on mechanism of IONM system.

Objective To explore the clinical significance of the disagreement between transmitral pulsed wave Doppler (PWD) and mitral annulus Doppler tissue imaging (DTI) in the estimation of left ventricular (LV) filling pressures. Methods One hundred and eighty-two sinus rhythm patients without arrhythmia, congenital heart disease and valvular disease underwent routine echocardiography and synchronous electrocardiogram for assessment of LV function. Early and late diastolic velocities of LV, which were composed of e and a waves, were recorded using DTI at the mitral annulus. Six sites at the mitral annuli were selected corresponding to the septal, lateral, anterior septal, posterior, inferior, and anterior walls of LV from apical 4-, 3-and 2-chamber views. Transmitral diastolic flow velocity, which was represented by E and A wave, was measured with PWD from apical 4-chamber view. Ratio of early and late diastolic transmitral valve (MV-E/A), ratio of DTI-e/a-ann and ratio of E/e-ann were calculated, respectively. The mean value of e-ann from the above 6 sites was selected to describe the early diastolic velocities of mitral annular. Results According to the results of MV-E/A ratio and DTI-e/a-ann ratios of the 6 sites, these 182 patients were divided into 4 groups: groupⅠ(n=68): MV-E/A<1.0, DTI-e/a-ann<1.0 at all the 6 sites at the same time, with mean MV-E/A ratio being 0.71±0.16 and mean E/e-ann ratio 15.91±6.78; groupⅡ(n=38): MV-E/A<1.0, DTI-e/a-ann≥1.0 at 1-6 sites among the total sites, with mean MV-E/A ratio being 0.76±0.12 and mean E/e-ann ratio 10.37±2.63; group Ⅲ(n=23): MV-E/A≥1.0, DTI-e/a-ann≥1.0 at all the 6 sites at the same time, with mean MV-E/A ratio being 1.74±0.42 and mean E/e-ann ratio 9.57±2.39; group Ⅳ(n=53): MV-E/A≥1.0, DTI-e/a-ann<1.0 at 1-6 sites among the total sites, with mean MV-E/A ratio being 1.31±0.31 and mean E/e-ann ratio 13.27±9.46. The mean ages of group Ⅰ, Ⅱand Ⅳ were older than that of group Ⅲ. Although there was no obvious difference between group Ⅰand groupⅡ in the mean age and mean MV-E/A (P>0.05), the mean E/e-ann was much higher in group Ⅰthan that in groupⅡ (P<0.05). The mean MV-E/A was similar in group Ⅲ and group Ⅳ (P>0.05), but the mean age and mean E/e-ann in the latter were older and higher than those in the former (P<0.05), respectively. The mean age in group Ⅳ was younger than that in group Ⅰand Ⅱ, while the mean E/e-ann in group Ⅳ was higher than that in group Ⅱ, but lower than group Ⅰ (P<0.05). Conclusion ①Ratio of MV-E/A <1.0 and ratios of DTI-e/a-ann <1.0 at all the 6 sites indicates increasing LV filling pressures; ②MV-E/A≥1.0 and DTI-e/a-ann<1.0 at 1-6 sites among the total sites predicts a tendency of high LV filling pressures; ③Wide variability may present in those with MV-E/A<1.0, DTI-e/a-ann≥1.0 at 1-6 sites among the total 6 sites or MV-E/A≥1.0, DTI-e/a-ann≥1.0 at all the 6 sites at the same time; ④Age of the patient has great influence on the measurement of MV-E/A ratio and DTI-e/a-ann ratio.
