Context: Arterial blood gases sampling is part of everyday nurses’ practice in the care of children
admitted to the pediatric intensive care unit, particularly for those receiving respiratory support. Aim: To evaluate
the effect of video-assisted teaching intervention on nurses’ knowledge and practice regarding arterial blood gases
sampling for ventilated children at pediatric intensive care units. Methods: A quasi-experimental research design
was utilized to conduct the current study. Settings: The study was conducted at Pediatric Intensive Care Units
(PICUs) of Benha University Hospital and Benha Specialized Pediatric Hospital at Benha city. Sampling: A
convenient sample of (70) nurses working at the above-mentioned settings were included in this study regardless of
their personal characteristics. Tools of data collection: Two tools used, Tool 1: A structured interviewing
questionnaire designed to assess nurses’ personal characteristics, personal data of the studied children, and nurses'
knowledge regarding arterial blood gases sampling. Tool 2: An observation checklist to assess nurses' practice
regarding arterial blood gases sampling. Results: There was a significant improvement in nurses’ total knowledge
and practice regarding arterial blood gases sampling after video-assisted teaching intervention. Conclusion: It can
be concluded that video-assisted teaching intervention had a positive effect on the improvement of nurses'
knowledge and practice level, which indicates that the video-assisted teaching intervention is an effective method.
Recommendation: The study recommended that applying the video-assisted teaching intervention for nurses
caring for ventilated children helps to promote and update their knowledge and ensure competent practice.
