UNLABELLED Objective : Esophageal stethoscope has the advantage of being non-invasive, easily placed and capability to monitor the heart sound. This study was designed to determine whether the ratio of S1 to S2 analyzed by esophageal stethoscope and wireless bluetooth transmission can be accurate indicator that express the correlation with blood pressure. METHODS Total 33 adult male and femal...

background: the basic requirements for monitoring anesthetized patients during surgery are assessing cardiac and respiratory function. esophageal stethoscopes have been developed for this purpose, but these devices may not provide clear heart and lung sound due to existence of various noises in operating rooms. in addition, the stethoscope is not applicable for continues monitoring, and it is u...

To the Editor:—We read with interest the case report by Williams et al. of an accidental middle turbinectomy during nasotracheal intubation. Though the authors stated it as being the first case, there have been some earlier reports on middle turbinectomy. Prewarming of endotracheal tube (ETT) to soften, lubricating of the ETT, and using a vasoconstrictor have been recommended to reduce trauma d...

BACKGROUND Epistaxis is the most common complication of nasotracheal intubation. We compared endotracheal tubes (ETT) obturated with an inflated esophageal stethoscope with normal ETTs with regard to the prevention of epistaxis and navigability, both with and without thermosoftening. METHODS Dental surgical patients requiring nasotracheal intubation were randomly allocated into 1 of 4 groups ...

We theoretically investigate the interplay between charge ordering and magnetic states in quasi-one-dimensional molecular conductors TMTTF(2)X, motivated by the observation of a complex variation of competing and/or coexisting phases. We show that the ferroelectric-type charge order increases two-dimensional antiferromagnetic spin correlation, whereas in the one-dimensional regime two different...

OBJECTIVE The use of an esophageal stethoscope is a basic heart sounds monitoring procedure performed in patients under general anesthesia. As the size of the first heart sound can express the left ventricle function, its correlation with cardiac output should be investigated. The aim of this study was to investigate the effects of cardiac output (CO) on the first heart sound (S1) amplitude. Me...

was erosion of the patient’s nasogastric tube through the anterior esophageal wall into the trachea. The finding that the defect was larger on the esophageal side than on the tracheal side makes bronchoscopy an unlikely cause. None of the other common causes of TEF in adults (radiation therapy, trauma, corrosive burn, malignancy, congenital defect, or tuberculosis) apply to this patient. There ...

OBJECTIVE To develop recommendations for positioning the second-generation pacing esophageal stethoscope for transesophageal atrial pacing in patients positioned prone (P), right lateral decubitus (RLD), and left lateral decubitus (LLD). DESIGN Prospective; patients assigned consecutively. SETTING Tertiary and university hospitals. PARTICIPANTS Thirty (10 in each position group) adult pat...
