Abstract
BACKGROUND
Complex intra-abdominal infections (cIAIs), often associated with abdominal trauma, have a complex etiology, are acute and severe, and have a high risk. They are an important cause of death in patients with abdominal trauma. Safe and effective treatment strategies are the factors affecting the prognosis of such patients.
AIM
To investigate the efficacy and safey of ertapenem combined with metronidazole in the treatment of cIAIs as well as the impact on serum inflammatory markers and T lymphocyte subsets, recovery status, and treatment costs.
METHODS
A total of 92 patients with cIAIs treated at our hospital from June 2021 to January 2023 were randomly divided into a control group and a study group, with 46 cases in each group. After admission, both groups received puncture drainage, continuous double-cannula irrigation, anti-infection therapy, organ function support, nutritional support, and other treatments. On this basis, the control group was treated with piperacillin/tazobactam combined with metronidazole, while the study group was treated with ertapenem combined with metronidazole. The therapeutic effects, recovery conditions, treatment costs, serum inflammatory indicators [procalcitonin (PCT), Toll-like receptor 4 (TLR-4), tumor necrosis factor-α (TNF-α), and C-reactive protein (CRP)], T lymphocyte subsets (CD3+, CD4+, and CD4+/CD8+ ratio), acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score, sequential organ failure assessment (SOFA) score, adverse reactions, and bacterial culture results were compared between the two groups.
RESULTS
The total effective rate of the study group was 93.48%, significantly higher than that of the control group (78.26%; P < 0.05). After 3 d and 7 d of treatment, the levels of serum PCT, TLR-4, TNF-α, and CRP in the study group were significantly lower and the levels of serum CD3+ and CD4+ T lymphocytes and CD4+/CD8+ ratio were significantly higher than those of the control group (P < 0.05). The APACHEⅡ score and SOFA score of the study group were significantly lower than those of the control group after 3 d and 7 d of treatment (P < 0.05). The time to fever resolution, ICU stay duration, and hospital stay in the study group were significantly shorter than those of the control group, and the costs of drugs and other resources were less than those of the control group (P < 0.05). The incidence of adverse reactions in the study group was 4.35%, significantly lower than that of the control group (17.39%; P < 0.05). There was no significant difference in the distribution of pathogenic bacteria between the two groups before and after treatment (P > 0.05).
CONCLUSION
Ertapenem combined with metronidazole is effective in the treatment of cIAIs, which can reduce inflammation, improve immune function, control disease progression, reduce the risk of organ failure, reduce the economic burden of patients, and improve treatment safety.
