Case Series of Inflation Pressures of the Endotracheal Tube Cuffs among Intubated Patients at an Accident and Emergency Department in Hong Kong

Abstract

Despite the frequent use of endotracheal tubes in daily practice of emergency medicine, not much emphasis has been put on the measurement of cuff pressure. We attempted to conduct a case series study of prospectively recruited patients to illustrate the risk of inappropriate cuff inflation without manometry. It was found that the pilot balloon palpation was an inaccurate method to estimate cuff under- or over-inflation, with large discrepancies when compared with an objective measure. Such discrepancies might be independent of doctors' and nurses' working experience in airway management. Use of an aneroid manometer remains an economical and cost-effective way to obtain an instantaneous yet reasonably reliable result and should become a routine in emergency departments.
