Abstract

Purpose: The process of infection by bacteria and viruses involves invasion, establishment, growth, and parasitization. Poor oral hygiene and dysbiosis are significant risk factors for pneumonia. The aim of this study was to evaluate bacterial transport into the trachea during intubation for orthopedic surgery and the impact of oral hygiene treatment.

Methods: The study cohort included 53 patients with fracture who underwent surgical procedures under general anesthesia and were divided into two groups: an oral hygiene treatment (OHT) group (n = 27) and a control group (n = 26). Before intubation, the OHT group underwent preoperative oral hygiene treatment. Microbiological culture was used for detection and counting of bacteria from the oropharynx, trachea, and tip of the endotracheal tube (ETT).

Results: Patients in the OHT group had a lower pathogen detection rate and lower degree of bacterial colonization in the oropharynx, trachea, and ETT tip.

Conclusion: Preoperative oral hygiene treatment is able to reduce bacterial transport and colonization during orthopedic surgery, thus providing an important adjunct to pre-anesthesia care.

术前口腔卫生治疗可减少骨科手术插管期间的细菌迁移和定植

目的：细菌和病毒的感染过程包括入侵、建立、生长和寄生。口腔卫生差和菌群失调是肺炎的重要危险因素。本研究的目的是评估骨科手术插管期间细菌进入气管的情况以及口腔卫生治疗的影响：研究队列包括 53 名在全身麻醉下接受外科手术的骨折患者，并将其分为两组：口腔卫生治疗（OHT）组（n = 27）和对照组（n = 26）。插管前，OHT 组进行术前口腔卫生治疗。采用微生物培养法对口咽、气管和气管导管（ETT）顶端的细菌进行检测和计数：结果：口腔卫生治疗组患者的病原体检出率较低，口咽、气管和 ETT 尖端的细菌定植程度也较低：结论：术前口腔卫生治疗能够减少骨科手术中的细菌转运和定植，从而为麻醉前护理提供了重要的辅助手段。
