Effects of early intervention with low-dose dobutamine on pneumonia complicated by sepsis / 中国基层医药

ABSTRACT

Objective:To investigate the effects of early intervention with low-dose dobutamine on pneumonia complicated with sepsis.Methods:We retrospectively analyzed the clinical data of 200 patients with pneumonia complicated by sepsis who received treatment in the First People's Hospital of Taizhou from January 2015 to January 2018. We divided these patients into control and observation groups with 100 patients/group according to different treatment methods. The control group was treated with immunoglobulin and methylprednisolone and given ventilator-assisted ventilation. The observation group was given low-dose dobutamine based on the treatments given in the control group. Clinical efficacy, pulmonary function, the incidence of adverse reactions, length of hospital stay, time to dyspnea disappearance, organ failure rate, and mortality were compared between the two groups.Results:Total response rate was significantly higher in the observation group than in the control group [96.0% (96/100) vs. 77.0% (77/100), χ2 = 15.45, P < 0.05]. After treatment, improvements in the pulmonary function indexes [forced vital capacity, forced expiratory volume in one second, and forced expiratory volume in one second/forced vital capacity] in the observation group were superior compared with those in the control group ( t = -15.25, -34.56, -3.77, all P < 0.001). Length of hospital stay and time to dyspnea disappearance in the observation group were (4.23 ± 0.89) days and (3.21 ± 0.58) days, respectively, which were significantly shorter than those in the control group [(8.96 ± 1.58) days, (7.26 ± 0.24) days, t = -26.08, -64.52, both P < 0.001]. The incidence of adverse reactions, incidence of organ failure, and mortality in the observation group were 2.0% (2/100), 1.0% (1/100) and 2.0% (2/100) respectively, which were significantly lower than those in the control group [18.0% (18/100), 20.0% (20/100), 10.0% (10/100), χ2 = 16.80, 19.20, 5.67, all P < 0.05). Conclusion:Early intervention with low-dose dobutamine for the treatment of pneumonia complicated by sepsis can greatly improve clinical efficacy, reduce adverse reactions, decrease the incidence of organ failure and mortality, improve pulmonary function, and shorten the length of hospital stay and time to dyspnea disappearance.
