| Popis: | Objectives Crush syndrome (CS) is characterized by a systemic manifestation of traumatic rhabdomyolysis, leading to multiple organ dysfunction and death. Ischemia-reperfusion (IR) injury is commonly responsible for systemic response. Extending studies have shown that hydrogen gas treatment ameliorated IR injury in numerous experimental models; however, its effect on CS has not been well examined. This study aimed to investigate the effects of hydrogen gas inhalation following crush injury in an experimental model of CS. Methods Male Sprague-Dawley rats were subjected to experimental CS by applying a total of 3.0 kg weight to both hindlimb under general anesthesia for 6 h. Immediately after decompression, the animals were randomly placed in a gas chamber filled with either air or 1.3% hydrogen gas. Animals were sacrificed 18 h or 24 h following gas exposure for non-survival studies or for survival study, respectively. Results The rats with hydrogen treatment ( n = 6) had a higher 24-h survival than the rats with air treatment ( n = 9) (100% vs. 44%, p = 0.035). Lactate concentrations (2.9 ± 0.2 vs. 2.2 ± 0.2 mmol/L, p = 0.040) and creatine kinase (34,178 ± 13,580 vs. 5005 ± 842 IU/L, p = 0.016) were lower in the hydrogen group compared with the air group 18 h after decompression ( n = 4 in the air group, and n = 5 in the H 2 group). Histological analysis revealed that the damage to the rectus femoris muscle and kidney appeared to be ameliorated by hydrogen treatment. Conclusion Hydrogen gas inhalation may be a promising therapeutic approach in the treatment of CS. |
