Abstract:

 


Objective: Depending on the increase in inspired fractionated nitric oxide

fraction (FiN2O), cuff pressures in intubated patients are increased with diffusion

into endotracheal cuff during low-flow anesthesia (LFA) with nitrous

oxide (N2O). We compared pressures of air- and saline-inflated endotracheal

tube cuffs during LFA with N2O in our study.

Methods: We included 60 adult patients who were classified by the American

Society of Anesthesiologists as I/II in the study. After induction of anesthesia,

endotracheal cuffs of patients who were intubated were inflated

with air (Group A=30) and saline (Group S=30) to 25 cm water. Thus, two

equal randomized groups were separated. The anesthesia technique was

maintained with LFA and N2O. Endotracheal cuff pressures were continuously

measured with a pressure manometer, and inspired oxygen and N2O

levels and also 2 and 24 h after surgery for sore throat were recorded.

Results: There was no significant difference about demographic and intraoperative

data between the groups. Cuff pressures were significantly higher

in Group A than in Group S during all periods (p10 min=0.02, p<0.0001

for others). Group S had significantly higher values than Group A when

maximum cuff pressures were compared (37.60±3.16 vs. 29.96±3.34, respectively;

p<0.0001). There was a 51.9% positive correlation between cuff

pressure and FiN2O in Group A (r=0.519, p=0.048). Group Ahad significantly

higher level than Group S at postoperative 2 and 24 h when groups were

compared for postoperative sore throat without swallowing and swallowing

(p<0.05).

Conclusion: Under LFA with N2O, endotracheal cuff pressures during operation

and postoperative sore throat incidences in our study were significantly

higher in Group S than in Group A.
