Purpose: Inappropriate cuff inflations cause many complications.
A conventional pilot balloon palpation technique is insufficient to detect high cuff pressures, but is still preferred.
Hence, we conducted this study to identify effectiveness,preference and ease of use of a new estimation technique named “passive release technique” for endotracheal tube cuff inflation.
Methods: Twenty-nine nurses inflated cuffs by a pilot balloon palpation technique in manikins inserted with a 7.5 mm endotracheal tube. Then, being educated about passive release techniques, they inflated cuffs using such a passive release technique. Intracuff pressures and air volumes were measured by manometers and syringes. Preference and ease of use between the two methods were scored using a 10-point Likert scale.
Results: For the pilot balloon palpation technique, only 4nurses (13.8%) inflated cuffs within the normal range of pressures (normal: 15 to 30 mb) with an average of 39.3±34.0 cmH2O. For the passive release technique, 19 nurses (65.5%) inflated cuffs within the normal range of pressures with an average of 24.2±9.3 cmH2O (McNemar’s test,p<0.01). In the pilot balloon palpation technique, inflated air volumes of 7.8±2.0 ml were not significantly different from inflated air volumes 8.5±1.2 ml (p=0.07) for the passive release technique. But the difference was found to be statistically significant in a variance ratio test (F-test) (p<0.01).
In view of preference and ease of use between the two methods, mean values were not statistically different, 7.3±2.0 vs. 7.0±2.0 and 7.0±2.3 vs. 7.3±2.4, respectively.
Conclusion: When direct intracuff measurement is not available, a passive release technique using a syringe is an effective and easy method to achieve cuff inflation.
