A research group led by Kei Higashimori Hospital, Graduate School of Medicine, Osaka City University, found that patients can be prevented from spreading by wearing a surgical mask when examining a gastrocamera inserted through the nostril.It is likely to attract attention as a way to prevent the transmission of the new coronavirus to healthcare workers.
According to Osaka City University, the research group inspects the gastrocamera inserted through the nostrils separately when the mannequin wears a mask and when it does not, and sprays a fluorescent paint instead of a cough with a sprayer for inspection. Later pollution ranges were compared.
As a result, if the mask is not worn, fluorescent paint will adhere to the area around the mannequin's mouth, the endoscopist's gloves, precordium, abdomen, and shoe cover, and the fluorescent paint will also adhere to the floor up to about 1.5 meters from the bed. It was scattered.However, if the mask was worn, the fluorescent paint stayed only inside the mask of the mannequin, and nothing else was scattered.
Based on the results of this experiment, the research group conducted an examination of a gastrocamera inserted through the nostrils of 732 patients at the hospital attached to the Faculty of Medicine with a mask on, and no operability problems or patient distress were reported. ..
According to the research group, a gastrocamera examination inserted through the nose has less vomiting reflex and cough than the method of inserting through the mouth, and it is possible to completely cover the mouth with a mask, which is a great effect.
