Objective To investigate the value of alveolar lavage combined with insulin glargine and acarbose in pa-tients with diabetes mellitus and pulmonary infection.Methods Clinical data of 100 patients with diabetes mellitus combined with pulmonary infection admitted to Zhangpu County Hospital from August 2022 to November 2023 were retrospectively selected.According to different treatment methods,they were divided into control group(insulin glargine combined with traditional anti-infection therapy)and observation group(alveolar lavage combined with acar-bose therapy was implemented on the basis of the treatment regimen of the control group),with 50 cases in each group.Blood glucose,insulin secretion index and inflammatory response were compared between the two groups.Results Before treatment,there was no significant difference in blood glucose level and inflammatory factor level be-tween the two groups(both P>0.05).After treatment,the levels of blood glucose in the observation group were signifi-cantly lower than those in the control group,and the levels of inflammatory factors were better than those in the con-trol group,and the differences were statistically significant(all P<0.05).The homeostasis model assessment of insulin resistance of observation group was 2.15±0.20,wich was higher than that of control group 2.14±0.21,and the differ-ence was statistically significant(t=1.889,P<0.05).The homeostasis model assessment of insulin sensitivity and ho-meostasis model assessment of islet β cell function of observation group were significantly higher than those of control group,and the differences were statistically significant(both P<0.05).Conclusion The combined intervention program of alveolar lavage,insulin glargine and acarbose has been applied in patients with diabetes mellitus complicated with pulmonary infection,and the effect is significant and reliable.The indexes of inflammatory response,insulin secretion index and blood glucose level of patients have been significantly improved.
