Table 5.

Data of the reported intubation related injuries from two transnasal endoscopic examinations; before and 24 h after DLT extubation. All different criteria were scored from 0 to 3. (0 = not assessable, 1 = without pathological findings, 2 = minor injuries, 3 = severe injuries). Values ​​are expressed as median (25th - 75th percentile)
