ABSTRACT
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 4 nurses (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.
