Technological innovation to colostomy bags: quasi-experimental study.

Objective: To verify the effect of the bag with irrigation valve on the pattern of (dis)comfort of the colostomy person.

Method: Quasi-experimental study, with a single group, through pre and post-test, carried out from June to September/2020 with 33 colostomized patients from a municipal rehabilitation center in Rio de Janeiro, Brazil. The pattern of (dis)comfort was analyzed using fuzzy logic, considering the attributes of bag cleaning, gas elimination and odor control.

Results: When analyzing the difficulty presented in each attribute before (T0) and after intervention (T1), a reduction was observed in relation to "bag cleaning" for 17 (56.7%) participants, in "odor control", for 24 (80.0%) and "gas removal" for 16 (53.3%) participants. By crossing the three attributes at the two moments, 21 (69.9%) participants indicated a reduction in (dis)comfort at T1.

Conclusion: There was a reduction in the pattern of discomfort with the use of the bag with irrigation valve compared to the traditional colostomy bag.
