Hydromorphone Protects against CO2 Pneumoperitoneum-Induced Lung Injury via Heme Oxygenase-1-Regulated Mitochondrial Dynamics

Figure 6

Hydromorphone ameliorates the CO2 pneumoperitoneum-induced inflammatory response and oxidative stress in humans. (a) CC-16 levels, (b) ICAM-1 levels, (c) the PAB, and (d) HO-1 activity in human blood samples from the two groups at five time points ( per group). The data are the . All values were calculated by two-way repeated-measures ANOVA. , , and (the hydromorphone group vs. the morphine group). T0: when the patient entered the operating room; T1: immediately before pneumoperitoneum; T2: 30 minutes after establishment of pneumoperitoneum; T3: 1 h after establishment of pneumoperitoneum; T4: 2 h after establishment of pneumoperitoneum; T5: 5 min after tracheal extubation.
