目的运用支气管肺泡灌洗术治疗吸入性铅吸收患者,对比观察治疗后血铅值的改变,探讨肺灌洗术防治吸入性铅吸收的临床价值。方法将20例吸入性铅吸收者随机平均分成两组,肺灌洗组给予肺灌洗加驱铅,对照组仅给予驱铅,两组于治疗前后检测血铅值并对比治疗后血铅值的改变。结果两组患者经治疗后血铅值均下降至正常值范围,但肺灌洗组血铅值要低于对照组,两组比较差异有统计学意义(P<0.05)。结论支气管肺泡灌洗术对吸入性铅吸收(或铅中毒)患者的治疗有应用价值,可促进铅从肺内排出,减少铅在肺内吸收。
Objective To evaluate the clinical value of bronchoalveolar lavage in the treatment of patients with inhaled lead absorption and to observe the change of blood lead after treatment. Methods Twenty patients with inhaled lead were randomly divided into two groups. The lung lavage group was given lavage plus lead, while the control group was given lead only. The blood lead levels in both groups were measured before and after treatment and the blood lead levels Change. Results After treatment, the blood lead levels dropped to the normal range in both groups, but the blood lead level in the lung lavage group was lower than that in the control group. There was significant difference between the two groups (P <0.05). Conclusion Bronchoalveolar lavage has therapeutic value in the treatment of patients with inhaled lead (or lead poisoning), which can promote the excretion of lead from the lung and reduce the absorption of lead in the lung.
