Decrease the cuff pressure to 30 cm H2O by withdrawing a small amount of air from the balloon with a 10 mL syringe. The individual anesthesia care providers participated more than once during the study period of seven months. Standard cuff pressure is 25mmH20 measured with a manometer. Curiel Garcia JA, Guerrero-Romero F, Rodriguez-Moran M: [Cuff pressure in endotracheal intubation: should it be routinely measured?]. Air Embolism: Causes, Symptoms, and Diagnosis - Healthline ); and patients with known anatomical laryngeo-tracheal abnormalities were excluded from this study. 14231426, 1990. C. K. Cho, H. U. Kwon, M. J. Lee, S. S. Park, and W. J. Jeong, Application of perifix(R) LOR (loss of resistance) syringe for obtaining adequate intracuff pressures of endotracheal tubes, Journal of Korean Society of Emergency Medicine, vol. When should tracheostomy cuff be inflated deflated? Previous studies suggest that this approach is unreliable [21, 22]. American Society of Anesthesiology, Committee of Origin: Committee on Quality Management and Departmental Administration (QMDA). Google Scholar. An anesthesia provider inserted the endotracheal tubes, and the intubator or the circulating registered nurse inflated the cuff. The patient was the only person blinded to the intervention group. The pre-publication history for this paper can be accessed here:http://www.biomedcentral.com/1471-2253/4/8/prepub. 66.3% (59/89) of patients in the loss of resistance group had cuff pressures in the recommended range compared with 22.5% (20/89) from the pilot balloon palpation method. The magnitude of effect on the primary outcome was computed for 95% CI using the t-test for difference in group means. The AAFP recommends inflating the cuff using air in 0.5-mL increments from a 3-mL syringe until no leak can be heard when the rebreathing bag is squeezed and the pressure in . Catastrophic consequences of endotracheal tube cuff over-inflation such as rupture of the trachea [46], tracheo-carotid artery erosion [7], and tracheal innominate artery fistulas are rare now that low-pressure, high-volume cuffs are used routinely. 7 It has been shown that the best way to ensure adequate sealing and avoid underinflation (or overinflation) is to monitor the intracuff pressure periodically and maintain the intracuff pressure within Part of 6, pp. 345, pp. Considering that this was a secondary outcome, it is possible that the sample size was small, hence leading to underestimation of the incidence of postextubation airway complaints between the groups.
