The Investigation on Nosocomial Infection of Acinetobacter baumannii and the Clinical Analysis of Sequential Therapy of Cefoperazone/Sulbactam Sodium for Intracranial Infection

Abstract

Background. Intracranial infection is a serious complication after neurosurgery. According to a survey, the incidence of intracranial infection is about 2.2%-2.6%, and patients with severe symptoms may even pose a threat to their life safety. Objective. To explore the risk factors for intracranial infection caused by Acinetobacter baumannii after surgery and the clinical effect of sequential therapy of cefoperazone/sulbactam sodium. Methods. In this study, a retrospective study was used. In this case-control study, 48 cases of intracranial Acinetobacter baumannii infection after neurosurgery in our hospital from January 2016 to December 2021 were selected as the infection group, and 96 patients without intracranial infection after surgery during the same period were selected as the control group to study all kinds of related factors and analyze the risk factors for intracranial Acinetobacter baumannii infection; in addition, in accordance with the therapeutic regimen for anti-infection, the infection group was divided into the tigecycline group (patients with tigecycline therapy in this group) and the combined group (patients with tigecycline combined with cefoperazone/sulbactam sequential therapy), with 24 cases in each group in order to compare the therapeutic effects of the two groups. Results. Logistic regression factor model results show that increasing age of patients, surgical treatment for intracranial tumor or craniocerebral trauma, postoperative drainage time (≥3 days), and postoperative hospital stay (≥10 days) were the risk factors for postoperative intracranial infection of Acinetobacter baumannii in neurosurgical patients ( P < 0.05 ), and postoperative prophylactic antibiotic treatment can reduce the incidence of intracranial infection ( P < 0.05 ). The cerebrospinal fluid nucleated cell count, serum CRP, and serum PCT in the combined group 72 h after treatment were lower than those in the tigecycline group, and the difference was statistically significant ( P < 0.05 ). Compared with the clinical efficacy after 72-hour treatment, the cure rate and effective rate in the combined treatment group were 83.33% and 16.67%, respectively, and those in the tigecycline group were 54.17% and 33.33%, respectively. The invalid interest rate was 12.50%, and the combined treatment group was superior to the tigecycline group ( P < 0.05 ). Conclusion. For patients with craniocerebral surgery, targeted preventive interventions should be carried out for the risk factors that may lead to intracranial Acinetobacter baumannii infection. The clinical effect of tigecycline combined with cefoperazone and sulbactam sodium sequentially in the treatment of intracranial Acinetobacter baumannii infection is better.
