Objective To explore the related factors of contrast agent leakage in CT enhanced scanning and to find out its preventive measures.Methods The clinical data of 46 patients with iodine leakage in the CT enhanced scanning during 2015 were retrospectively analyzed.Results The leakage rate had statistically significant difference between different patient's genders(P＜0.05).The leakage rate was related to the age of the patients(P＜0.01).The leakage rate showed the increasing trend with the increase of injection rate(P＜0.05).The leakage rate was related to the concentration of the contrast agent(P＜0.05).The leakage rate had no increasing trend with the increase of injection dose(P=0.675).The leakage rate was related to the years of injection nurses engaging this working(P＜0.01).Conclusion The leakage rate of female patients was higher than that of male.The older the patients,the greater the contrast agent concentration,the faster the injection rate and the lower the working years of injection nurses,the greater the leakage rate.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) will reduce the cardiopulmonary function and increase perioperative risk. The aim of this study is to investigate the effect of preoperative short-term high intensity lung rehabilitation training on lung function and postoperative complications in patients with COPD who are eligible for lung cancer surgery. METHODS: We analysis of 101 patients with COPD and a diagnosis of lung cancer, with 43 patients in pulmonary rehabilitation group and 58 patients in conventional group. The pulmonary function, postoperative pulmonary complications (PPCs) and length of stay (LOS) will be compared between the two groups, the lung function will be compared before and after the rehabilitation at the same time. RESULTS: There were no significant difference between the two groups in general information, lung function before surgery, postoperative pulmonary infection [8 (18.6%) vs 17 (29.3%)], atelectasis [1 (2.3%) vs 1 (1.7%)], respiratory failure [1 (2.3%) vs 2 (3.4%)] and postoperative LOS [(8.93±3.78) d vs (9.62±3.98) d, P>0.05]. In the rehabilitation group, the FEV1 [(2.06±0.45) L vs (2.15±0.45) L, P<0.001] and PEF [(4.32±0.90) L/s vs (5.15±1.05) L/s, P<0.001) were higher, and PCO2 [(42.42±2.79) mmHg vs (41.58±2.98) mmHg, P=0.009] was lower after rehabilitation, significantly. The increase value of FEV1 in moderate to severe COPD group was higher than that of the mild COPD group after the rehabilitation [(0.16±0.05) L, 8.6% vs (0.06±0.05) L, 2.8%, P<0.001). CONCLUSIONS The short-term highly-intensity lung rehabilitation can improve lung function in lung cancer patients with COPD, and the improvement of pulmonary function in moderate to severe COPD patients is more obviously.
