目的探讨体外高频热疗对大容量肺灌洗患者短期肺功能恢复的影响。方法将48例接受大容量肺灌洗的煤工尘肺Ⅰ期男性患者随机分为治疗组和对照组,治疗组给予体外高频热疗,热疗温度为39~43℃,时间为40 min/次,隔日1次,连续3次。对照组不接受体外高频热疗。比较两组患者灌洗前后TLC、FVC、MVV、DLCO、FEV1.0%肺功能指标的变化。结果两组患者灌洗前后肺功能比较差异无统计学意义(P>0.05)。结论就本研究结果而言体外高频热疗对于肺灌洗患者术后肺功能的恢复无明显影响,其对肺灌洗患者或对尘肺病患者的疗效还有待进一步观察。
Objective To investigate the effect of high frequency hyperthermia in vitro on the recovery of short-term pulmonary function in patients with pulmonary lavage. Methods Forty-eight patients with stage Ⅰ coal-mine pneumoconiosis undergoing large-volume lung lavage were randomly divided into treatment group and control group. The treatment group was given high-frequency hyperthermia in vitro. The hyperthermia temperature was 39-43 ℃ and the time was 40 min / Times, every other day, 3 times in a row. The control group did not receive high frequency hyperthermia in vitro. The changes of pulmonary function indexes of TLC, FVC, MVV, DLCO and FEV1.0% before and after lavage were compared between the two groups. Results There was no significant difference in lung function between the two groups before and after lavage (P> 0.05). Conclusion In our study, in vitro HF hyperthermia had no significant effect on postoperative pulmonary function recovery in patients with pulmonary lavage. The efficacy of HF HF in patients with lung lavage or pneumoconiosis remains to be further observed.
