Abstract:
Objective:To assess their influence on position,age,pepsin in gastric juice and different diseases to aspiration of gastric contents.Methods:To choice pepsin levels in tracheal aspirates as an indicator,the own control designing was adopted in the present study.Twenty mechanical ventilated children in different diseases who were 0-8 years old were nursed prone position and 30?supine fowler position.Tracheal aspirates were harvested at 1 hour,2 hours and 3 hours in different body positions and pepsin levels in tracheal aspirates were measured.At the same time pepsin levels in gastric contents were measured.Results:At the same time pepsin levels in tracheal aspirates at prone positioning were obviously less than that at 30?supine fowler position(P0.05).Conclusion:Aspiration of gastric contents at prone positioning were smaller than that at 30?supine fowler position.Pepsin levels may generally apply in paediatrics as an indicator.
