The aim of this study was to compare the rate of successful first-pass intubation in the ICU by using the direct laryngoscopy(DL) and that by using the video laryngoscopy(VL).METHODS: A randomized, non-blinded trial comparing first-pass success rate of intubation between VL and DL was performed. Patients were recruited in the period from August 2014 to August 2016. All physicians working at ICU received hands-on training in the use of the video and direct laryngoscope. The primary outcome measure was the first-pass intubation success. RESULTS: A total of 163 ICU patients underwent intubation during the study period(81 patients in VL group and 82 in DL group). The rate of successful first-pass intubation was not significantly different between the VL and the DL group(67.9% vs. 69.5%, P=0.824). Moreover, the overall intubation success and total number of attempts to achieve intubation success did not differ between the two groups. In patients with successful first-pass intubation, the median duration of the intubation procedure did not differ between the two groups. The Cormack-Lehane grades and the percentage of glottic opening score were similar, and no significant differences were found between the two groups. There were no statistical differences between the VL and the DL group in intubation complications(all P>0.05). CONCLUSION: Among ICU patients requiring intubation, there was no significant difference in the rate of successful first-pass intubation between VL and DL.展开更多

Setting: Academic tertiary care medical centre. Materials and Methods: 50 patients with complaints of hoarseness of voice were clinically evaluated and diagnosis was made using Rigid Videolaryngoscopy, Flexible Videolaryngoscopy and Videostroboscopy. Patients underwent microlaryngeal surgery and a final diagnosis made with histopathological examination. The intra-operative findings and the final histopathological diagnosis were compared with the diagnosis made with rigid, flexible videolaryngoscopy and stroboscopy. Results: Intra-operative findings correlated with stroboscopic findings in 84% of patients, with fibreopticlaryngo-pharyngoscopic diagnosis in 54% of patients and with rigid video-laryngoscopy in 46% of patients. Videostroboscopy showed the highest diagnostic co-relation on histopathology (80%) as compared to rigid videoendoscopy (56%) and flexible videolaryngoscopy (58%). Videostroboscopy also elucidated vocal fold abnormalities that were missed on rigid or flexible laryngoscopic examinations. Conclusion: Videostroboscopy is a valuable complement to a thorough vocal history and physical examination. Videostroboscopy is superior to constant light laryngeal examination in diagnosis of vocal cord lesions.展开更多
