Military personnel with a diagnosis of asthma report increased respiratory symptoms in the deployment and post-deployment periods. The long-term effect of deployment on pulmonary function in this population is unknown. This study sought to determine the effect of deployment on post-deployment pulmonary function in active duty military personnel with asthma.
A retrospective chart review of active duty military personnel with deployment to southwest Asia and an ICD-9 diagnosis of asthma with documented pre- and post-deployment spirometry was performed.
A total of 642 active duty individuals with a diagnosis of asthma and documented spirometry with deployment to southwest Asia between 2006 and 2015 were identified. Of these, 76 individuals were identified with pre- and post-deployment spirometry. There was no significant change in the post-deployment forced expiratory volume at 1 second (% predicted), from 86.0 ± 14.8 to 87.6 ± 14.4 (P = .30). There was no significant change in post-deployment forced vital capacity (% predicted), from 93.8 ± 12.4 to 94.9 ± 12.1 (P = .42). The absolute change in forced expiratory volume at 1 second (L) after bronchodilator administration was decreased from pre-deployment to post-deployment (+0.31 ± 0.26 to +0.16 ± 0.23; P = .02).
There was no significant post-deployment change in spirometry in this military population with asthma deployed to southwest Asia. These findings suggest that deployment itself is not associated with any short-term deleterious effect on post-deployment spirometric measures of lung function in many military personnel with asthma.
被诊断为哮喘的军事人员报告称，在部署期间和部署后，呼吸道症状有所增加。部署对该人群肺功能的长期影响尚不清楚。本研究旨在确定部署对患有哮喘的现役军事人员部署后肺功能的影响。
对部署到西南亚且有国际疾病分类第九版（ICD-9）哮喘诊断记录以及部署前后肺活量测定记录的现役军事人员进行回顾性病历审查。
共识别出642名在2006年至2015年期间被诊断为哮喘且有部署到西南亚记录以及肺活量测定记录的现役人员。其中，76人有部署前后的肺活量测定记录。部署后第1秒用力呼气量（预测值百分比）无显著变化，从86.0±14.8降至87.6±14.4（P = 0.30）。部署后用力肺活量（预测值百分比）无显著变化，从93.8±12.4降至94.9±12.1（P = 0.42）。支气管扩张剂给药后第1秒用力呼气量（升）的绝对变化从部署前到部署后有所下降（从+0.31±0.26降至+0.16±0.23；P = 0.02）。
部署到西南亚的患有哮喘的军事人群在部署后肺活量测定方面无显著变化。这些发现表明，在许多患有哮喘的军事人员中，部署本身与部署后肺功能的肺活量测定指标的任何短期有害影响无关。
