Abstract Background Microaspiration of gastric and oropharyngeal secretions is the main causative mechanism of ventilator-associated pneumonia (VAP). Transesophageal echocardiography (TEE) is a routine investigation tool in intensive care unit and could enhance microaspiration. This study aimed at evaluating the impact of TEE on microaspiration and VAP in intubated critically ill adult patients. Methods It is a four-center prospective observational study. Microaspiration biomarkers (pepsin and salivary amylase) concentrations were quantitatively measured on tracheal aspirates drawn before and after TEE. The primary endpoint was the percentage of patients with TEE-associated microaspiration, defined as: (1) ≥ 50% increase in biomarker concentration between pre-TEE and post-TEE samples, and (2) a significant post-TEE biomarker concentration (> 200 μg/L for pepsin and/or > 1685 IU/L for salivary amylase). Secondary endpoints included the development of VAP within three days after TEE and the evolution of tracheal cuff pressure throughout TEE. Results We enrolled 100 patients (35 females), with a median age of 64 (53–72) years. Of the 74 patients analyzed for biomarkers, 17 (23%) got TEE-associated microaspiration. However, overall, pepsin and salivary amylase levels were not significantly different between before and after TEE, with wide interindividual variability. VAP occurred in 19 patients (19%) within 3 days following TEE. VAP patients had a larger tracheal tube size and endured more attempts of TEE probe introduction than their counterparts but showed similar aspiration biomarker concentrations. TEE induced an increase in tracheal cuff pressure, especially during insertion and removal of the probe. Conclusions We could not find any association between TEE-associated microaspiration and the development of VAP during the three days following TEE in intubated critically ill patients. However, our study cannot formally rule out a role for TEE because of the high rate of VAP observed after TEE and the limitations of our methods.

Abstract Background: High cuff pressure can induce ischemic injury to the trachea. An esophageal stethoscope can increase the cuff pressure. The purpose of this study was to evaluate the effect of an esophageal stethoscope insertion on the cuff pressure.Methods: Patients, who were scheduled for surgeries under general anesthesia, were enrolled in this prospective observational study. After induction of anesthesia, an anesthesiologist intubated a tracheal tube into the patient’s trachea and inflated the cuff manually. Then, an investigator checked the initial cuff pressure using a manometer. Next, the cuff pressure was adjusted to 24-26 mmHg. The cuff pressure was rechecked after insertion of an esophageal stethoscope. We recorded the change in cuff pressure by esophageal stethoscope.Results: One hundred twelve patients completed this study. The cuff pressure increased by an esophageal stethoscope in almost all patients and the mean cuff pressure change was 3.0 ± 3.4 cmH2O in all patients. Among all subjects, cuff pressure change over 5 cmH2O was recorded in 24 patients. When we compared the patient characteristics between patients whose cuff pressure changed over 5 cmH2O with that of other patients, females were more affected by insertion of an esophageal stethoscope, in terms of cuff pressure increase.Conclusion: Esophageal stethoscope insertion could increase cuff pressure, and females are more affected by it. Therefore, anesthesiologists should check the cuff pressure with a manometer after insertion of an esophageal stethoscope and readjust the pressure appropriately.Trial registration: ClinicalTrials.gov Identifier NCT03375554, registered on 12 December 2017 (https://register.clinicaltrials.gov/prs/app/action/SelectProtocol?sid=S0007N0H&selectaction=Edit&uid=U00026JX&ts=2&cx=-ivu5vz)
