气管梗阻性呼吸困难的Nd:YAG激光治疗

Nd∶YAG Laser Treatment for Obstructive Tracheal Dyspnea

为了寻求治疗气管梗阻性呼吸困难的理想方法，１９８７年６月至１９９５年２月，我们应用ＮｄＹＡＧ激光治疗气管梗阻性呼吸困难８例，其中气管医源性肉芽肿３例、气管成形术后吻合口狭窄１例、恶性肿瘤４例。呼吸困难重度者４例、中度者４例。呼吸困难均于首次治疗获得明显改善，无明显不良反应。结果提示，ＮｄＹＡＧ激光用于解除气管梗阻性呼吸困难是一种有效的急救方法。

The aim of this study is to explore an optimal procedure to treat severe tracheal dyspnea. From June 1987 to February 1995, Nd∶YAG laser photoresection was performed on eight patients with obstructive tracheal dyspnea complicated with severe intratracheal lesions due to tracheostomy granulomas, tracheal sleeve anastomosis and tracheal malignant tumors. Severe dyspnea complicated with benign lesions occurred in 4 out of the 8 cases. Moderate dyspnea due to malignant tumors were in four patients. Significant improvement revealed immediately following the first therapy in all of the patients. No severe complication was observed during or after the procedure. The results suggest that Nd∶YAG laser photoresection is an effective method as the first aid of obstructive tracheal dyspnea complicated with severe intratracheal lesions.
