目的 分析胃肠间质瘤患者行胸腹盆CT屏气训练影响因素.方法 分析2017年1-6月北京肿瘤医院收治的胃肠间质瘤患者70例,男36例,女34例,年龄(59.4±3.1)岁.均接受胸腹盆CT检查,检查前进行屏气训练,分析年龄、性别、焦虑情况、肺功能、听力、地域差异(语言差异)、体力不支、疼痛情况等因素对屏气训练有何影响.结果 70例患者在胸腹盆CT检查时屏气成功者42例,成功率60.0％.男性和女性的屏气成功率间比较差异无统计学意义.40~60岁者、无焦虑者、无肺功能低下者、无听力障碍者、无地域差异(语言差异)者的屏气训练成功率显著高于61~75岁者、焦虑者、肺功能低下者、有地域差异者、和有体力不支、疼痛者(均P＜0.05).结论 胃肠间质瘤患者行胸腹盆CT屏气训练的成功率与年龄、听力、地域差异(语言沟通障碍)、焦虑、肺功能低下、疼痛等因素密切相关.“,”Objective To investigate the influencing factors of breath holding training beforethoracic, abdominal, and pelvic CT examination in patients with gastrointestinal stromal tumor.Methods 70 patients with gastrointestinal stromal tumor diagnosed by pathological examination, 36 males and 34 females, aged (59.4 ±3.1) (40~76), underwent thoracic, abdominal,and pelvic CT examination. Before the CT edxamination, they underwent breath holding training. The correlations of the relevant factors, such as gender, age, anxiety, pulmonary function, hearing disorder, geographicdifferences (language/dialect barrier), physical strength, and pain with the success rate of breath holding training were analyzed. Results 42 of the 70 patients were successfully trained in breath holding with a success rate of 60％. There was no significant difference in the success rate of breath holding training between the male and female patients. The success rates of breath holding training of the patients aged 40~60,those without anxiety, with normal pulmonary function, without hearing disorder, without geographic differences (language/dialect barrier),were all significantly higher than those of the patients aged 61~75,with anxiety, with pulmonary insufficiency, with hearing disorder, and with geographic differences (language/dialect barrier) (all P ＜0.05). Conclusion The success rate of breath holding training before thoracic, abdominal, and pelvic CT examination in the patients with gastrointestinal stromal tumor is closely correlated with age, listening comprehension,geographic differences (language/dialect barrier), anxiety, pulmonary function, pain, and wether being with obstructive pulmonary emphysema, chronic bronchitis, and asthma.
