Purpose of the study: Aspiration of stomach contents is a serious side effect in patients with a feeding tube which can
be prevented otherwise may lead to death. There have been disputes over the safest feeding method. Therefore, this
study seeks to identify the chance of occurrence of respiratory aspiration in two tube feeding methods of intermittent
bolus and intermittent drip bag in patients of the ICU and trauma ward.
Methods: In this quasi-experimental study, investigating contextual variables and using gradual method, 72 patients in
ICU and trauma ward who were fed through tubes were divided into two groups of intermittent bolus and intermittent
drip bag method and both groups were independently fed for 3 days. After that, both groups were surveyed and
compared based on the level of aspiration occurrence. To collect the data, personal information, nutrition, and
respiration form as well as form of information about the two feeding methods in the studied units were utilized. The
studied units were selected among Training and Treatment Centers in Rasht in 2010. To analyze the data, descriptive
and inferential statistics and SPSS16 software were used.
Results: The findings showed that respiratory aspiration occurrence level in intermittent bolus tube feeding methods
was 5.6% whereas this amount in intermittent drip bag method was zero. Fisher exact test revealed that there was no
significant relationship between these two groups (P=0.47).
Conclusion: As there was no significant relationship in respiratory aspiration between the two groups, it was concluded
that intermittent bolus method can still be mentioned in books as a standard method to decrease the risk of aspiration if
it is used properly.
