Introduction: Principled endotracheal suctioning (ETS) performed by nurses can reduce complications, duration of hospitalization and
mortality in critically-ill patients in the intensive care unit (ICU). Aim: The present study was conducted to determine the effect of training on nurses’ performance in terms of the ETS of patients in the ICUs of Imam Khomeini Medical Educational Center in Ardabil,
Iran based on clinical indicators. Methods: This single-blinded randomized clinical trial recruited 47 nurses working in the ICUs of
Imam Khomeini Medical Educational Center in 2018-19. The participants were randomly assigned into an intervention group and a
control group. Data collection tools included a standard performance checklist for nurses in the field of ETS. The data were analyzed
in SPSS-22 using statistical tests. Results: The mean score of the nurses’ performance in terms of ETS was 12.04±3.08 in the
intervention group and 12.29±2.38 in the control group (P=0.75) before training, and 15.13±2.78 in the intervention group and
12.16±2.82 in the control group (P<0.001) after training. Conclusion and implications: The results showed that teaching ETS
standards improves the performance of nurses in the ICU. Therefore, it is recommended to consider teaching ETS standards in health
system planning and policy making.
