目的总结应用支纤镜行支气管肺泡灌洗治疗尘肺病患者的疗效及并发症的防治。方法对46例尘肺患者WLL术前和术后的症状评分和动脉血气行统计学t检验,并观察手术并发症。结果本组46例尘肺病患者中,行双肺同期大容量灌洗36例,单侧分期灌洗10例。全部患者术后3～5d胸闷、胸痛、气喘症状消失或明显好转,肺通气功能及临床症状评分明显改善(P<0.05)。术后未出现肺部感染、肺水肿、液气胸、气道痉挛及出血等并发症,均痊愈出院。结论 WLL治疗各期尘肺安全有效,能明显改善症状,改善通气和换气功能,明显提高动脉血氧分压,减少慢性阻塞性肺疾病、肺心病等合并症。
Objective To summarize the curative effect and prevention and treatment of pneumoconiosis patients treated with bronchial alveolar lavage. Methods 46 patients with pneumoconiosis WLL preoperative and postoperative symptom scores and arterial blood gas statistics t test, and observe the surgical complications. Results In the group of 46 patients with pneumoconiosis, 36 cases were treated with high-capacity lavage of both lungs simultaneously and 10 cases were unilateral lavage. All patients had chest tightness, chest pain, asthma symptoms disappeared or markedly improved 3 to 5 days after operation, and pulmonary ventilation and clinical symptom scores improved significantly (P <0.05). No postoperative pulmonary infection, pulmonary edema, fluid pneumothorax, airway spasm and bleeding complications were cured and discharged. Conclusion WLL is safe and effective in treating pneumoconiosis at various stages, which can significantly improve symptoms, improve ventilation and ventilatory function, significantly improve arterial partial pressure of oxygen, reduce complications such as chronic obstructive pulmonary disease and pulmonary heart disease.
