Use of AccuCuffTM for continuous monitoring of cuff pressure: a clinical trial

Abstract

delivered through a ventilatory prosthesis. This device consists of a cuff, a cuff that requires calibration and seals the space between the ventilatory prosthesis and the trachea, preventing respiratory complications or leaks during ventilation. Objective: To analyze the use of a low-cost device for continuous cuff pressure monitoring and compare clinical outcomes. Methods: This is a randomized clinical trial conducted in an adult intensive care unit with intubated patients on mechanical ventilation for up to 48 hours. Patients were followed throughout the study period, according to their allocation. The AccuCuff™ device was used for continuous cuff pressure measurement, which was compared to conventional care, which used a cuffometer as an assessment tool. Results: Fifty-five patients of both sexes participated in the study; 27 used the AccuCuff and 28 received conventional care. The results show homogeneity of characteristics between the groups. Regarding cuff pressure behavior, both groups experienced only one drop in pressure, with a similar percentage and no significant difference regarding the need for adjustments between periods (p = 0.307). Conclusion: The continuous cuff measurement device represents a viable alternative, producing values consistent with its specifications and being easy to monitor, making it a viable alternative within the hospital setting. Regular intervals between measurements are recommended to prevent prolonged periods of low pressure.
