Brief summary

Compare the radiation in pediatric patients thyroid submitted to chest X-ray using the position of the anode and cathode.

Detailed description

The study's primary goal was to compare radiation exposure in two different positions during chest x rays in children. It was conducted from June/2014 to July/2015, and included children from 0 to12 years old staying at the Pediatric Intensive Care Unit at the Instituto de Cardiologia de Porto Alegre, Brazil, with chest x ray requests during ICU stay. They were randomized to two groups: during the x ray, one group was positioned with the thyroid facing the anode end, and the other group was positioned with the thyroid facing the cathode end.

Interventions

OTHERThyroid facing the anode end of xray machine

Thyroid position: facing the anode end of xray machine

OTHERThyroid facing the cathode end of xray machine

Thyroid position: facing the cathode end of xray machine
