Table 4 Change in BWT

From: Chest computed tomography performed on admission helps predict the severity of smoke-inhalation injury

  Admission 24 hours 7 days
Total BWT    
m (SD) 2.45 (1.26) 3.40 (1.20)a 1.49 (0.64)ab
N 37 29 29
BWT of SII alone    
m (SD) 2.43 (1.26) 3.18 (1.00)a 1.52 (0.68)ab
Number 29 23 23
BWT of SII with cutaneous burn    
m (SD) 2.53 (1.34) 4.16 (1.71)a 1.42 (0.68)ab
Number 8 6 6
  1. BWT, bronchial-wall thickness; SD, standard deviation; SII, smoke-inhalation injury.
  2. aP < 0.001 versus admission BWT; bP < 0.001 versus 24 hours BWT. BWT values in the 7-days-after group were significantly lower than those in the admission (P < 0.001) and 24-hours-after (P < 0.001) groups. BWT values in the 7-days-after group with SII alone and SII with cutaneous burn were significantly lower than those in the admission (P < 0.001) and 24-hours-after (P < 0.001) groups.
