A Wireless Electronic Esophageal Stethoscope for Continuous Monitoring of Cardiovascular and Respiratory Systems during Anaesthesia
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...
متن کاملUse of esophageal stethoscope as an introducer during nasotracheal intubation.
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...
متن کاملA new technique to reduce epistaxis and enhance navigability during nasotracheal intubation.
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 ...
متن کاملCorrelation of blood pressure and the ratio of S1 to S2 as measured by esophageal stethoscope and wireless bluetooth transmission
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...
متن کاملThe correlation between the first heart sound and cardiac output as measured by using digital esophageal stethoscope under anaesthesia
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...
