Abstract: 間接接触感染の一因として、気管カニューレ内への不適切なカテーテル操作がある。しかしながら、気管内吸引中の接触面積や接触箇所に基づいた感染予防法について報告された論文は少ない。また、CDCのガイドラインにおいても、気管内吸引に未滅菌の手袋よりも滅菌手袋を着用することについてのエビデンスはなく、未解決問題となっている。そこで本研究では、接触感染の感染経路解明のパイロットスタディとして、気管内吸引三法の手技中に実施者が接触する箇所と面積を比較し、各法の接触感染リスクの定量的評価を目的に、吸引シミュレータと使用物品に付着した蛍光塗料の付着部位の撮影と接触面積を計測した。その結果、清潔操作が必要な物品への接触面積は各法で大差は認められなかったが、閉鎖式気管内吸引の間接接触感染リスクが比較的低いことが示された。
Rights: Inappropriate catheterizations into tracheostomy tubes cause the indirect contact transmission; however, there are currently few studies reports on the infection prophylaxis based on the area and place of contact during endotracheal suctioning. There is no evidence about the benefits of wearing sterilised gloves compared to non-sterilised gloves for endotracheal suctioning in the CDC guidelines, and this remains an unsolved problem. Therefore, we conducted a pilot study to quantitatively evaluate the risks of secondary contact infection associated with three methods of endotracheal suctioning. Contaminated items and the gross area that the subjects touched during the procedures were measured. As a result, no differences in the gross area on consumables requiring aseptic manoeuvres were found; however, the gross area of the closed suctioning system was the smallest, implying that the risk of indirect contact transmission might be relatively low among these procedures.
