To study the efficacy of AG CUFFILL (Digital) compared to that of standard PORTEX cuff inflator/pressure analog gauge for the measurement of endotracheal tube cuff pressure

Abstract

Endotracheal tube (ETT) is commonly used to provide positive pressure ventilation. ETT cuff pressure is maintained within a range of 20 to 30 cmH2O. High pressure affects micro-circulation and integrity of the tracheal mucosa, resulting in complications. The cuff pressure is measured by connecting a pressure gauge device to pilot balloon. Two variety devices are available; analog or digital manometers. Present study is used to study the efficacy of AG CUFFILLL (Digital) compared with standard PORTEX Cuff inflator/pressure gauge (Analog) for the measurement of ETT cuff pressure.This study was conducted after obtaining institutional ethical clearance and written informed consent.100 patients between the age of 18-70yrs who fulfilled inclusion criteria. We measured ETT cuff pressure using AG CUFFILL (Digital) and standard PORTEX Cuff inflator/pressure gauge and compared the pressure recording of the two equipment and we studied ease of use for both.Out of 100 patients between the age of 18-70yrs, 61 patients (61%) were male and 39 patients (39%) were female. Mean cuff pressure of ETT using AG CUFFILL was 36.29±6.36 cmH2O and in PORTEX was 33.97±6.16cm H2O. Mean difference in the values between the cuff pressure measured by AG CUFFILL and PORTEX was ± 2.67. Comparing the two devices, it was noticed that in 05 (5%) patients measuring ETT cuff pressure using AG CUFFILL was difficult as the values were fluctuating. Based on results, authors recommend AG CUFFILL for ETT cuff pressure measurement owing to its accuracy, non-bulky, and ease to carry.
