不同负压吸引联合胸腔闭式引流术治疗自发性气胸的临床疗效

Clinical efficacy of different negative pressure suction combined with closed thoracic drainage on spontaneous pneumothorax

目的探究不同负压吸引联合胸腔闭式引流术治疗自发性气胸的临床疗效。方法选取2019年1月至2020年10月本院收治的120例自发性气胸患者作为研究对象,依据双盲随机分组法分为3组,各组40例。3组均实施持续负压吸引+胸腔闭式引流术治疗,A组为低负压(-5 cmH_(2)O),B组为中负压(-10 cmH_(2)O),C组为高负压(-20 cmH_(2)O)。比较3组临床疗效、并发症发生情况、肺复张及住院等时间。结果B组治疗总有效率显著高于A组、C组,差异有统计学意义(P<0.05);A组、C组组间比较差异无统计学意义。B组并发症发生率显著低于A组、C组,肺复张时间及住院时间均显著短于A组、C组,差异有统计学意义(P<0.05);A组、C组组间并发症发生率、肺复张时间及住院时间比较差异无统计学意义。结论自发性气胸采用中负压(-10 cmH_(2)O)吸引联合胸腔闭式引流术治疗效果显著,可减少并发症的发生,加速肺复张,促进患者病情康复,值得临床推广应用。

Objective To study the clinical efficacy of different negative pressure suction combined with closed thoracic drainage on spontaneous pneumothorax.Methods 120 patients with spontaneous pneumothorax admitted to our hospital from January 2019 to October 2020 were selected as subjects,and they were divided into three groups according to double blind random grouping method,with 40 cases in each group.All three groups were treated with continuous negative pressure suction+closed thoracic drainage.Group A had low negative pressure(-5 cmH_(2)O),Group B had medium negative pressure(-10 cmH_(2)O),and Group C had high negative pressure(-20 cmH_(2)O).The clinical efficacy,complications,lung recruitment time and hospitalization time were compared among the three groups.Results The total effective rate of group B was significantly higher than that of group A and group C(P<0.05);There was no significant difference between group A and group C.The incidence of complications in group B was significantly lower than that in group A and group C,and the time of lung recruitment and hospitalization were significantly shorter than those in group A and group C(P<0.05);there was no significant difference in the incidence of complications,time of lung recruitment and hospitalization between group A and group C.Conclusion The treatment of spontaneous pneumothorax with medium negative pressure(-10 cmH_(2)O)suction combined with closed thoracic drainage is effective,which can reduce various complications,accelerate lung recruitment,and promote the recovery of patients,and is worthy of clinical application.
