Effects of Bronchoalveolar Lavage with Ambroxol Hydrochloride on Treating Pulmonary Infection in Patients with Cerebral Infarction and on Serum Proinflammatory Cytokines, MDA and SOD

OBJECTIVE: This paper was aimed at investigating the effects of bronchoalveolar lavage (BAL) with ambroxol hydrochloride (AH) on treating pulmonary infection and on serum proinflammatory cytokines and oxidative stress responses in patients with cerebral infarction (CI). METHODS: One hundred and two patients with cerebral infarction complicated with pulmonary infection (CIPI) who were treated in our hospital were enrolled as research objects, divided into an observation group (52 cases; AH combined with BAL) and a control group (50 cases; single AH) based on therapeutic schemes. They were compared in terms of the therapeutic effect and pre- and posttreatment serum inflammatory cytokines, pulmonary function, and serum indices of oxidative stress. Their adverse reactions during treatment were also recorded and compared. RESULTS: The therapeutic effect in the observation group was remarkably better than that in the control group (P < 0.05). After treatment, the serum inflammatory cytokines, pulmonary function, and serum indices of oxidative stress were remarkably improved in the two groups (P < 0.05), but the improvement was remarkably better in the observation group (P < 0.05). The differences were not significant in intratreatment adverse reactions between the two groups (P > 0.05). CONCLUSION: For CIPI patients, BAL with AH has a better therapeutic effect and higher safety and can control the patients' systemic inflammatory responses and oxidative stress responses, so it is worthy of further promotion in clinical practice.
