In the present study, to more understand the therapeutic efficacy of direct hemoperfusion with polymixin B-immobilized fibers (PMX-DHP), we investigated changes of tissue oxygenation by using NIRS and compared before and after PMX-DHP treatment. We measured oxygenated hemoglobin (Oxy-Hb), deoxygenated hemoglobin (Deoxy-Hb), total hemoglobin (Total Hb) and cytochrome a,a_3 (Cyt a,a_3) at forehead and forearm using NIRS. Data obtained by using a Swan-Ganz catheter was used to derive systemic VO_2 (oxygen consumption), DO_2 (oxygen delivery), O_2EI (oxygen extraction index), SVRI (systemic vascular resistance index) and SvO_2 (mixed venous oxygen saturation). At forearm, Cyt a,a_3 significantly increased after PMX-DHP (p<0.05). At forehead, there were no changes of Cyt a,a_3 (p=0.39) between before and after PMX-DHP. And there were no significant changes in VO_2, DO_2, O_2EI, SVRI, SvO_2 blood lactate concentration, base excess and IL-6. After PMX-DHP treatment, Oxy-Hb, Deoxy-Hb, Total Hb and Cyt a,a_3 increased at the forearm. But at forehead, Cyt a,a_3 was unchanged. This result suggests PMX-DHP could increase blood volume and tissue oxygen metabolism in skeletal muscles in septic shock.","subitem_description_type":"Abstract"}]},"item_10001_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"300347","nameIdentifierScheme":"WEKO"}],"names":[{"name":"武重, 徹"}]},{"nameIdentifiers":[{"nameIdentifier":"300348","nameIdentifierScheme":"WEKO"}],"names":[{"name":"矢口, 有乃"}]},{"nameIdentifiers":[{"nameIdentifier":"300349","nameIdentifierScheme":"WEKO"}],"names":[{"name":"花房, 茂樹"}]},{"nameIdentifiers":[{"nameIdentifier":"300350","nameIdentifierScheme":"WEKO"}],"names":[{"name":"原田, 知幸"}]},{"nameIdentifiers":[{"nameIdentifier":"300351","nameIdentifierScheme":"WEKO"}],"names":[{"name":"鈴木, 忠"}]}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京女子医科大学学会"}]},"item_10001_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AN00161368","subitem_source_identifier_type":"NCID"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0040-9022","subitem_source_identifier_type":"ISSN"}]},"item_10001_subject_47":{"attribute_name":"著者キーワード","attribute_value_mlt":[{"subitem_subject":"sepsis","subitem_subject_scheme":"Other"},{"subitem_subject":"polymyxin B","subitem_subject_scheme":"Other"},{"subitem_subject":"cytochrome a,a_3","subitem_subject_scheme":"Other"},{"subitem_subject":"near-infrared spectroscopy","subitem_subject_scheme":"Other"},{"subitem_subject":"intensive care unit","subitem_subject_scheme":"Other"}]},"item_10001_text_35":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Department of Critical Care and Emergency Medicine, Tokyo Women's Medical University, School of Medicine"},{"subitem_text_value":"Department of Critical Care and Emergency Medicine, Tokyo Women's Medical University, School of Medicine"},{"subitem_text_value":"Department of Critical Care and Emergency Medicine, Tokyo Women's Medical University, School of Medicine"},{"subitem_text_value":"Department of Critical Care and Emergency Medicine, Tokyo Women's Medical University, School of Medicine"},{"subitem_text_value":"Department of Critical Care and Emergency Medicine, Tokyo Women's Medical University, School of Medicine"},{"subitem_text_value":"東京女子医科大学医学部救急医学"},{"subitem_text_value":"東京女子医科大学医学部救急医学"},{"subitem_text_value":"東京女子医科大学医学部救急医学"},{"subitem_text_value":"東京女子医科大学医学部救急医学"},{"subitem_text_value":"東京女子医科大学医学部救急医学"}]},"item_10001_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-08-22"}],"displaytype":"detail","filename":"KJ00006018344.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00006018344.pdf","url":"https://twinkle.repo.nii.ac.jp/record/19981/files/KJ00006018344.pdf"},"version_id":"7f7b7ef9-5eb3-4546-81af-c40d071fa8ea"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Evaluation of Changes in Oxygenation by Near Infrared Spectroscopy during Direct Hemoperfusion with Polymyxin B Immobilized Fibers","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Evaluation of Changes in Oxygenation by Near Infrared Spectroscopy during Direct Hemoperfusion with Polymyxin B Immobilized Fibers"}]},"item_type_id":"10001","owner":"3","path":["2012"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-08-10"},"publish_date":"2010-08-10","publish_status":"0","recid":"19981","relation_version_is_last":true,"title":["Evaluation of Changes in Oxygenation by Near Infrared Spectroscopy during Direct Hemoperfusion with Polymyxin B Immobilized Fibers"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-20T20:53:00.787008+00:00"}
