Rotterdam CT Score Measures by Resuscitation Type

Measure	LTOWB (n = 98)	COMPONENT (n = 42)	p Value
Rotterdam score
First CT scan, mean ± SD	2.34 ± 0.90	2.33 ± 1.05	0.82
Second CT scan, mean ± SD*	2.78 ± 1.50	2.74 ± 1.52	0.95
Difference, mean ± SD	0.44 ± 1.05	0.40 ± 1.04	0.87
Worsening, n (%)†	21 (21.4)	13 (31.0)	0.23

^*19 patients died before they could be scanned for a second time. The scores for these patients have been set to 6.

^†Because 71.4% of patients experienced no change in scores, this measure distinguishes those whose score became worse compared with those whose score remained unchanged or improved (n = 1).

COMPONENT, blood component resuscitation; LTOWB, low-titer group O whole blood.
