Treatment group
Morphine (n=17)Diamorphine (n=20)p (MWU test)
Plasma adrenaline at T0 (median + IQR)1.48  (0.59–3.74)1.08  (0.73–2.67)0.95
Median change in plasma adrenaline T0–T24 (p value)−0.93 (0.001)−0.58 (0.001)0.34
Plasma noradrenaline at T0 (median + IQR)3.29 (2.90–6.83)3.86 (1.89–7.81)0.55
Median change in plasma noradrenaline T0–T24 (p value)−2.07 (0.005)−0.62 (0.20)0.13
  • IQR = interquartile range; T0 = time of starting infusion; T24 = 24 h after starting infusion
