Brief Summary

Evaluation of the application effect of compound chlorhexidine gargle in oral care of patients with endotracheal intubation based on 16s RNA technology.

Detailed Description

Evaluation of the application effect of compound chlorhexidine gargle in oral care of patients with endotracheal intubation based on 16s RNA technology. Between September 2022 and March 2023, 68 patients admitted to the ICU for endotracheal intubation were collected. They were randomly divided into intervention group and control group, with 34 cases in each group. The control group used the method of wiping, washing and saline (0.9%) three times a day, and the intervention group was using the method of wiping, washing and 0.12% chlorhexidine gluconate three times a day.The results were analyzed at three time points before the first oral care after intubation, before oral care 48 hours after intubation, and before oral care on the 5th day after intubation.

objective analysis results based on 16s RNA technology

Secondary Outcome Measures
NameTimeMethod
oral complicationsmechanical ventilation at 0 hours, 2 days, and 5 days post-intervention

Oral complication occurrences: The occurrences of oral mucosa bleeding, oral inflammation, oral ulcers, fungal and herpes virus infections, tongue falling backwards, laryngeal edema, granulomas, and other complications were recorded in elderly patients undergoing mechanical ventilation at 0 hours, 2 days, and 5 days post-intervention. Diagnosis was confirmed through blood routine tests, histopathological examinations, smear tests, fungal cultures, or other methods.

plaque Indexmechanical ventilation at 0 hours, 2 days, and 5 days post-intervention

Dental Plaque Index: The mesial buccal, middle buccal, distal buccal, and lingual surfaces of the teeth in elderly patients undergoing mechanical ventilation were examined and scored using a combination of visual inspection and probing. A score of 0 indicates no plaque at the gingival margin, 1 indicates a thin layer of plaque at the gingival margin, 2 indicates moderate plaque at the gingival margin or interproximal area, and 3 indicates abundant soft debris within the gingival sulcus, at the gingival margin, and in the interproximal area. The Dental Plaque Index is calculated as the sum of the plaque scores for each tooth divided by the total number of teeth examined.

whether VAP occursImmediately after enrollment; 48 hrs after intubation;5 days after intubation

the recorder records whether VAP occurs after endotracheal intubation;Ventilator-associated pneumonia (VAP) refers to pneumonia that occurs between 48 hours after the initiation of mechanical ventilation (MV) and 48 hours after extubation. It is an important type of hospital-acquired pneumonia (HAP). Among them, pneumonia that occurs within 4 days of MV is classified as early-onset VAP, while that occurring on or after the 5th day is classified as late-onset VAP.
