目的 探讨床旁电子支气管镜治疗ICU中小儿重症肺炎33例疗效及安全性.方法 将60例ICU中重症肺炎患儿随机分成治疗组和对照组.治疗组给予床旁电子支气管镜灌洗治疗,对照组则给予重症肺炎常规抗感染、气道内吸痰等基础治疗.比较两组的治疗效果.结果 治疗组患儿留住ICU时间(4.20±0.86)d,总住院日(11.53±3.21)d,机械通气时间(3.52±0.61)d,灌洗前后血气分析PaCO2下降(15.40±4.58)及PaO2升高(14.80±12.15),结果均优于对照组(P<0.05).结论 及时采用床旁电子支气管镜进行灌洗治疗小儿重症肺炎,可以显著改善患儿的临床症状,明显改善血气分析结果,降低气管插管几率及机械通气治疗时间.可以明显缩短留住ICU时间及总住院日,值得临床推广.“,”Objective to study the efficacy and safety of bedside electronic bronchoscopy in treatment of children with severe pneumonia in ICU.Methods 60 children with severe pneumonia, aged (5.73±5.12) years, were randomly divided into 2 groups: control group (n=27) given routine treatment including medication against infection, sputum suction, etc., and treatment group (n=33) undergoing lavage with normal saline via bedside electronic bronchoscopy. The therapeutic effects of these 2 groups were compared. Results The length of ICU stay, total hospitalization time, and mechanical ventilation time of the treatment group were (4.20+0.86) d, (11.53+3.21) d, and (3.52+0.61) d respectively, all significantly shorter than those of the control group [(6.51±2.30) d , (15.63±4.52) d, and (5.18±1.43) d respectively, all P<0.05]. The PaCO2 and PaO2 after lavage of the treatment group were (15.40 ± 4.58) mmHg and (14.80 ± 12.15) mmHg respectively, both significantly higher than those of the control group [(4.50 ± 4.37) mmHg, and (10.40 ± 5.28) mmHg respectively, both P<0.05]. Conclusion Bedside electronic bronchoscope lavage treatment of children with severe pneumonia significantly improves the clinical symptoms and blood gas analysis, shortens the mechanical ventilation treatment timeand hospital stay time, and reduces the economic burden of the families of patiens.
