Clinical Analysis of Multi-drug Resistant Bacteria Infection in Patients with Oral and Maxillofacial Surgery

Abstract

Objective: To investigate and analyze the multi-drug resistant bacteria infection in patients with oral and maxillofacial surgery in
order to provide scientific basis for preventing and controlling the infection transmission of multi-drug resistant bacteria in hospital environment. Methods: A total of 100 patients hospitalized in the oral and maxillofacial surgery department of our hospital from March 2022 to
March 2024 were tested for multidrug-resistant bacteria infection. Results: Among 100 patients in oral and maxillofacial surgery, the target
pathogens were detected in 22 patients, the detection rate was 18.03%. The main pathogenic bacteria were Escherichia coli (45.45%), Proteus
Mirabilis, methicillin-resistant Staphylococcus aureus, Klebsiella pneumoniae and Klebsiella acidophilus. Esbls-producing Escherichia coli
accounted for all multi-drug resistant infections. Surgical site accounted for 27.27%, lower respiratory tract accounted for 36.64%, and the
main type of infected patients was oral malignant tumor (45.45%). Conclusion: The infection rate of multi-drug resistant bacteria is high in
patients with oral and maxillofacial surgery, and Escherichia coli is the main pathogen. Most infections are caused by wound infection, and
multi-drug resistant bacteria are particularly prevalent in oral cancer patients.
