Effect of small-dose levosimendan on mortality rates and organ functions in Chinese elderly patients with sepsis.

AIM

As a primary cause of death not only in Western countries but also in the People's Republic of China, sepsis is diagnosed as abnormal organ functions as a result of a disordered response to a severe infection. This study was designed to assess the effect of small-dose levosimendan without a loading dose on mortality rates and organ functions in Chinese elderly patients with sepsis.

METHODS

Following a prospective, randomized, and double-blinded design, 240 Chinese elderly patients with sepsis shock were admitted to the intensive care unit (ICU). All patients were randomly and evenly assigned into a levosimendan group (number of patients =120) and a control group (number of patients =120). The control group underwent standard care, and the levosimendan group was administered levosimendan in addition to standard care.

RESULTS

All participants, comprising 134 males (55.8%) and 106 females (44.2%), were 70 (67-73) years old. Baseline characteristics, preexisting illnesses, initial infections, organ failures, and additional agents and therapies showed no significant difference between the two groups (>0.05 for all). There were no significant differences in mortality rates at 28 days, at ICU discharge, and at hospital discharge between the two groups (>0.05 for all). The number of days of ICU and hospital stay in the levosimendan group was significantly less than for those in the control group (<0.05 for all). Mean daily total sequential organ failure assessment score and all organ scores except the cardiovascular scores showed no significant difference between the two groups (>0.05 for all). Cardiovascular scores in the levosimendan group were significantly higher than those in the control group (<0.05 for all).

CONCLUSION

Small-dose levosimendan could not reduce the mortality rates or enhance the respiratory, liver, renal, and coagulation functions, but could shorten the days of ICU and hospital stay, and improve the cardiovascular function, which suggests that small-dose levosimendan is valuable for Chinese elderly patients with sepsis.
