ABSTRACT

OBJECTIVE To compare the clinical effects of different doses of meropenem in the treatment of septic shock. METHODS One hundred and six patients with septic shock were randomly divided into standard-dose group and high-dose group， with 53 cases in each group. Patients in the standard-dose group were given standard dose of meropenem （initial intravenous injection of 1 g meropenem more than 30 minutes， followed by 1 g meropenem intravenously every 8 hours， each time for more than 3 hours）； patients in the high-dose group were given high dose of meropenem （initial intravenous injection of 2 g meropenem more than 30 minutes， followed by 2 g meropenem intravenously every 8 hours， each time for more than 3 hours）； other treatment measures were determined based on the specific conditions of the patients. The main observation indicators were the increments of sequential organ failure assessment （SOFA） scores and simplified acute physiology score Ⅱ （SAPS Ⅱ） after 3， 5 and 7 days of treatment in both groups. Secondary observation indicators included in-hospital mortality， 90-day all-cause mortality， 7-day microbial cure rate， 7-day clinical cure rate， serum procalcitonin （PCT） and C-reactive protein （CRP） levels after 3， 5 and 7 days of treatment， hospitalization days in the intensive care unit， ventilator treatment days， the highest dose of norepinephrine. The occurrence of adverse drug reaction in the two groups was observed. RESULTS The increments of SOFA scores and SAPS Ⅱ after 7 days of treatment， the levels of PCT and CRP after 5 and 7 days of treatment as well as the 90-day all-cause mortality in the high- dose group were significantly lower than the standard-dose group （P＜0.05）. There were no statistically significant differences in other indicators between the two groups （P＞0.05）. CONCLUSIONS High-dose meropenem treatment for septic shock has better clinical effects and is safer than standard-dose meropenem.
