BACKGROUND Multidrug-resistant Gram-negative bacteria,exacerbated by excessive use of antimicrobials and immunosuppressants,are a major health threat.AIM To study the clinical efficacy and safety of colistin sulfate in the treatment of carbapenem-resistant Gram-negative bacilli-induced pneumonia,and to provide theoretical reference for clinical diagnosis and treatment.METHODS This retrospective analysis involved 54 patients with Gram-negative bacilli pneumonia admitted to intensive care unit of The General Hospital of the Northern Theater Command of the People's Liberation Army of China from August 2020 to June 2022.After bacteriological culture,the patients'airway secretions were collected to confirm the presence of Gram-negative bacilli.The patients were divided into the experimental and control groups according to the medication used.The research group consisted of 28 patients who received polymyxin sulfate combined with other drugs through intravenous,nebulization,or intravenous combined with nebulization,with a daily dosage of 1.5–3.0 million units.The control group consisted of 26 patients who received standard dosages of other antibiotics(including sulbactam sodium for injection,cefoperazone sodium sulbactam for injection,tigecycline,meropenem,or vaborbactam).RESULTS Of the 28 patients included in the research group,26 patients showed improvement,treatment was ineffective for two patients,and one patient died,with the treatment efficacy rate of 92.82%.Of the 26 patients in the control group,18 patients improved,treatment was ineffective for eight patients,and two patients died,with the treatment efficacy rate of 54.9%;significant difference was observed between the two groups(P<0.05).The levels of white blood cell(WBC),procalcitonin(PCT),and C-reactive protein(CRP)in both groups were significantly lower after treatment than before treatment(P<0.05),and the levels of WBC,PCT,and CRP in the research group were significantly lower than those in the control group(P<0.05).Compared with before treatment,there were no significant changes in aspartate aminotransferase,creatinine,and glomerular filtration rate in both groups,while total bilirubin and alanine aminotransferase decreased after treatment(P<0.05)with no difference between the groups.In patients with good clinical outcomes,the sequential organ failure assessment(SOFA)score was low when treated with inhaled polymyxin sulfate,and specific antibiotic treatment did not improve the outcome.Sepsis and septic shock as well as a low SOFA score were independent factors associated with good clinical outcomes.CONCLUSION Polymyxin sulfate has a significant effect on the treatment of patients with multiple drug-resistant Gram-negative bacilli pneumonia and other infections in the lungs and is safe and reliable.Moreover,the administration route of low-dose intravenous injection combined with nebulization shows better therapeutic effects and lower adverse reactions,providing new ideas for clinical administration. 展开更多
