Background. Both under- and overinflation of endotracheal tube cuffs can result in significant harm to the patient. The optimaltechnique for establishing and maintaining safe cuff pressures (20–30cmH2O) is the cuff pressure manometer, but this is not widelyavailable, especially in resource-limited settings where its use is limited by cost of acquisition and maintenance. Therefore, anesthesiaproviders commonly rely on subjective methods to estimate safe endotracheal cuff pressure. This study set out to determine theefficacy of the loss of resistance syringe method at estimating endotracheal cuff pressures. Methods. This was a randomized clinicaltrial. We enrolled adult patients scheduled to undergo general anesthesia for elective surgery at Mulago Hospital, Uganda. Studyparticipants were... randomized to have their endotracheal cuff pressures estimated by either loss of resistance syringe or pilot balloonpalpation. The pressures measured were recorded. Results. One hundred seventy-eight patients were analyzed. 66.3% (59/89) ofpatients in the loss of resistance group had cuff pressures in the recommended range compared with 22.5% (20/89) from the pilotballoon palpation method. This was statistically significant. Conclusion.The loss of resistance syringe method was superior to pilotballoon palpation at administering pressures in the recommended range. This method provides a viable option to cuff inflation.
