For avoiding the complication due to hypothermia, many warming devices and methods have been used in perioperative period. It has been reported that more patients undergoing laparoscopic surgery tend to have hypothermia than with open surgery. To avoid intraoperative hypothermia, many kinds of warming tools have been used. But, it was also reported that some warming methods increased perceptions of distraction and physical demand.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>To achieve both patients\u2019 normothermia and surgeons\u2019 comfort, new air conditioning (AC) system was designed with considering the characteristics of laparoscopic surgery. The temperature of the airflows to the patient and to the surgeons can be adjusted independently in this new system. The new system has two parts. One controls the temperature of the central area over the operation table. The air from this part falls on the patients. The other part is the lateral area beside the operating table; the air from this part falls on the surgeons. The subjects of this study were 160 gastric cancer patients and 316 colorectal cancer patients undergoing laparoscopic surgery. The temperature of the central flow was set 23.5\u00a0\u00b0C, and the temperature of the lateral flow was set 22\u00a0\u00b0C just after the anesthesia. The number of timepoints the patient spent in hypothermic state, defined as a temperature cooler by 0.5\u00a0\u00b0C or more than that at the starting point of surgery, was determined in each patient.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>In the results, the rate of hypothermic state in old operation rooms was 23.8% and that in new operation rooms was 2.7% in male gastric cancer patients (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.01). And those were 37.1% in old operation rooms and 0.9% in new operation rooms in female gastric cancer patients (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.01). The rate of hypothermic state in old operation rooms was 30.0% and that in new operation rooms was 9.5% in male colorectal cancer patients (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.01). And those were 41.6% in old operation rooms and 8.9% in new operation rooms in female colorectal cancer patients (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.01). The similar results were showed in the study, which subjects were limited the patients undergoing surgery in 2015 and 2016; which were the last year the old operation rooms were used and the first year the new operation rooms were used.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Thus, the usefulness of the new air conditioning system for achieving both patients\u2019 normothermia and comfort of surgeons could be verified in this study.<\/jats:p><\/jats:sec>","DOI":"10.1007\/s00268-019-05203-8","type":"journal-article","created":{"date-parts":[[2019,10,10]],"date-time":"2019-10-10T20:04:12Z","timestamp":1570737852000},"page":"45-52","update-policy":"http:\/\/dx.doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["New Concept Air Conditioning System for the Operating Room to Minimize Patient Cooling and Surgeon Heating: A Historical Control Cohort Study"],"prefix":"10.1002","volume":"44","author":[{"given":"Hisashi","family":"Usuki","sequence":"first","affiliation":[{"name":"Surgical Center Kagawa University Hospital Ikenobe 1750\u20101, Miki Kita Kagawa Japan"},{"name":"Department of Gastroenterological Surgery, Faculty of Medicine\/Graduate School of Medicine Kagawa University Ikenobe 1750\u20101, Miki Kita Kagawa Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroaki","family":"Kitamura","sequence":"additional","affiliation":[{"name":"Surgical Center Kagawa University Hospital Ikenobe 1750\u20101, Miki Kita Kagawa Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yasuhisa","family":"Ando","sequence":"additional","affiliation":[{"name":"Department of Gastroenterological Surgery, Faculty of Medicine\/Graduate School of Medicine Kagawa University Ikenobe 1750\u20101, Miki Kita Kagawa Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hironobu","family":"Suto","sequence":"additional","affiliation":[{"name":"Department of Gastroenterological Surgery, Faculty of Medicine\/Graduate School of Medicine Kagawa University Ikenobe 1750\u20101, Miki Kita Kagawa Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eisuke","family":"Asano","sequence":"additional","affiliation":[{"name":"Department of Gastroenterological Surgery, Faculty of Medicine\/Graduate School of Medicine Kagawa University Ikenobe 1750\u20101, Miki Kita Kagawa Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Minoru","family":"Ohshima","sequence":"additional","affiliation":[{"name":"Department of Gastroenterological Surgery, Faculty of Medicine\/Graduate School of Medicine Kagawa University Ikenobe 1750\u20101, Miki Kita Kagawa Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takayoshi","family":"Kishino","sequence":"additional","affiliation":[{"name":"Department of Gastroenterological Surgery, Faculty of Medicine\/Graduate School of Medicine Kagawa University Ikenobe 1750\u20101, Miki Kita Kagawa Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kensuke","family":"Kumamoto","sequence":"additional","affiliation":[{"name":"Department of Gastroenterological Surgery, Faculty of Medicine\/Graduate School of Medicine Kagawa University Ikenobe 1750\u20101, Miki Kita Kagawa Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Keiichi","family":"Okano","sequence":"additional","affiliation":[{"name":"Department of Gastroenterological Surgery, Faculty of Medicine\/Graduate School of Medicine Kagawa University Ikenobe 1750\u20101, Miki Kita Kagawa Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yasuyuki","family":"Suzuki","sequence":"additional","affiliation":[{"name":"Department of Gastroenterological Surgery, Faculty of Medicine\/Graduate School of Medicine Kagawa University Ikenobe 1750\u20101, Miki Kita Kagawa Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2019,10,10]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1097\/00019509\u2010199704000\u201000018"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1089\/089277902760367412"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00464\u2010001\u20109055\u20100"},{"key":"e_1_2_7_5_1","doi-asserted-by":"crossref","unstructured":"CampbellG AldersonP SmithAFet al.
