New Hope for Sepsis Treatment: How Hydrogen-Rich Saline and Propofol Can Help

Researchers in China found that a combination of propofol and hydrogen-rich saline can reduce organ damage and inflammation in mice with sepsis. This promising approach could lead to new treatments for sepsis, a life-threatening condition that happens when the body's response to an infection gets out of control. The study suggests a potential new way to turn down the body's alarm system and reduce damage.

Methods

Results: The 1, 2, 3, 5, 7 days survival rate of septic mice were 80%, 40%, 20%, 10%, and 0%, respectively. The survival rate of animals increased significantly after propofol or hydrogen-rich treatment, and the combined treatment can further increase survival rate to 90%, 75%, 60%, 55%, and 55%, respectively. Compared with the sham group, inflammatory factors were significantly increased in blood and organ tissues, cell degeneration, necrosis, congestion and inflammatory cell infiltration in lung, liver and kidney, and tissues histological scores were significantly increased. The levels of inflammatory factors were reduced in blood and tissues, cell degeneration, necrosis, congestion and inflammatory cell infiltration were alleviated in lung, liver and kidney, and tissues histological scores were decreased after propofol or hydrogen-rich treatment compared with CLP group; these indicators were further improved in propofol and H2 group compared with propofol group or H2 group [2, 3, 5, 7-day survival rate: 75% vs. 60%, 65%; 60% vs. 50%, 50%; 55% vs. 45%, 40%; 55% vs. 40%, 40%; blood TNF-α (ng/L): 367±74 vs. 612±132, 588±117; blood IL-1β (ng/L): 321±68 vs. 502±95, 476±86; blood HMGB1 (μg/L): 4.6±0.9 vs. 7.0±1.4, 6.8±1.3; lung TNF-α (ng/g): 307±70 vs. 512±132, 488±102; lung IL-1β (ng/g): 367±77 vs. 571±108, 466±89; lung HMGB1 (μg/g): 5.1±1.0 vs. 7.8±1.7, 7.1±1.5; liver TNF-α (ng/g): 247±57 vs. 431±112, 389±87; liver IL-1β (ng/g): 267±58 vs. 417±85, 399±76; liver HMGB1 (μg/g): 4.2±1.1 vs. 7.1±1.6, 6.6±1.2; kidney TNF-α (ng/g): 257±41 vs. 480±89, 448±82; kidney IL-1β (ng/g): 258±39 vs. 409±68, 411±66; kidney HMGB1 (μg/g): 3.9±0.7 vs. 6.8±1.2, 5.7±1.0; histological scores: lung: 1.22±0.28 vs. 2.61±0.49, 2.58±0.44; liver: 1.38±0.32 vs. 2.76±0.51, 2.62±0.46; kidney: 1.19±0.25 vs. 2.43±0.41, 2.36±0.40; all P < 0.05]. Conclusions: Both propofol and H2 can improve the survival rate of sepsis, reduce tissue damage and the release of cytokines, and combined application of the two treatment was better.
