Results: The clinical indexes and total effective rate in the observation group were significantly better than those in the control group (P <0.05). Conclusion: Compared with the conventional western medicine, the combination of painless bronchoalveolar lavage and injection of drugs in treating bronchiectasis complicated with infection has obvious curative effect.
