Abstract:
Objective:To investigate the effect of bronchoalveolar lavage fluid(BALF)cytology examination combined with lymphocyte immunoassay on clinical outcome of critically ill patients with stroke-associated pneumonia(SAP).Methods:One hundred and fifty-six critically ill patients with SAP admitted to Department of Respiratory and Critical Care Medicine of the Second People's Hospital of Weifang from September 2021 to June 2022 were selected,and randomly divided into a study group and a control group,with 78 cases in each group.Control group was treated with conventional pulmonary infection,and study group added bronchoscopic alveolar lavage treatment based on the treatment of control group,and the anti-infection treatment regimen was adjusted according to the results of BALF lymphocyte immunoassay.Clinical improvement rates,clinical symptom scores,serum inflammatory factors[procal-citonin(PCT),C-reactive protein(CRP),TNF-α],peripheral blood lymphocyte subsets(CD3+T,CD4+T,CD8+T)levels,treatment condition,in-hospital mortality and incidence of acute respiratory distress syndrome(ARDS)between the two groups were compared.Results:Clinical improvement rates were higher in study group(44.87%,58.97%,91.03%,97.44%)than that in control group(26.92%,42.31%,78.21%,88.46%)at 3 d,5 d,7 d and 10 d of treatment(P<0.05);serum PCT,CRP and TNF-α levels were lower in study group than that in control group after 10 d of treatment(P<0.05);peripheral blood CD3+T,CD4+T,CD8+T levels were higher in study group than that in control group after 10 d of treatment(P<0.05).CPIS and CURB-65 scores were lower in study group than that in control group after 10 d of treatment(P<0.05);duration of antimicrobial drug use,duration of mechanical ventilation,and length of hospital stay were shorter in study group than that in control group(P<0.05);in-hospital mortality rate(7.69%)and inci-dence of ARDS(5.13%)were lower in study group than that in control group(19.23%,15.38%)(P<0.05).Conclusion:Optimized anti-infection treatment plan based on BALF cytology examination combined with lymphocyte immunoassay can significantly improve clinical efficacy of critically ill patients with SAP,and help to promote recovery and improve the prognosis of patients.
