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。
In order to seek an ideal method for treatment of tracheal obstructive dyspnea, from June 1987 to February 1995, we used NdYAG laser in the treatment of 8 cases of tracheal obstructive dyspnea, including 3 cases of iatrogenic granuloma of the trachea and anastomosis after tracheoplasty. There were 1 case of stenosis and 4 cases of malignancy. There were 4 cases with severe dyspnea and 4 cases with moderate dyspnea. The dyspnea was significantly improved in the first treatment and no significant adverse reactions were observed. The results suggest that NdYAG laser is an effective first aid method to relieve tracheal obstructive dyspnea.
