Nevertheless, if we divided the
patients by age group according to standard pain scores
for age, patients aged more than four to eight years old
had less pain in the group receiving fentanyl than the
group given ketamine, 1.331.27 (median 2; range 0-4)
and 2.831.86 (median 2; range 0-8), respectively
(p = 0.002) as shown in Fig. 1.
