腹腔鏡手術における術中体位を目視できる透明ドレープの開発―患者および医療者からの包括的評価

Development of a transparent drape to observe intraoperative positioning in laparoscopic surgery : Comprehensive assessment in the medical professions and patients

◆要旨：腹腔鏡下手術において体位保持の観察を容易にするため，下肢を目視できる透明ドレープを開発し，従来の不織布ドレープと比較した．不織布群25名，透明群25名で手術時間，ドレープ下の温度と湿度，体温，神経障害の有無を収集した．全例で神経障害は認めず，透明群は不織布群より温度が平均1.0℃，体温は0.3℃高かった．医療者には職業性ストレス簡易調査票による評価と半構成的面接を行った．ストレス尺度では不織布使用後6名のストレスが高い傾向にあった．半構成的面接ではストレスが減ったという意見が多かった．透明群はドレープ内の環境も不織布群と大差なく，異常の早期発見ができ，患者と医療者の両側面で有用であった．

In order to facilitate observation of patient's positioning during laparoscopic surgery, a transparent drape to observe the lower limb directly was developed and compared with non-woven surgical drape. Between 25 patients in non-woven and 25 in transparency groups, operative time, humidity and temperature under drape, body temperature, and neuropathy were examined. No postoperative neurological impairment occurred in any patient. The mean temperature and the body temperature were 1.0℃ and 0.3℃ higher in the transparency group than the non-woven fabric group, respectively. For the medical staffs, semi-structured interview and occupational stress simple-questionnaire were conducted. In the stress scale, the score of six staffs was higher before the use of non-woven drape. In semi-structured interviews, most of the staffs mentioned that the level of stress decreased after the use of transparency drape. The transparency drape showed similar environment within the drape to non-woven surgical drape, and it could be useful in detecting abnormality during operation at early stage.
