摘　　要：目的探讨主动呼吸控制(ABC)技术在CT引导下肺部小结节穿刺活检中的应用价值.方法选取肺部小结节(≤2 cm)穿刺活检患者70例,其中实验组25例,对照组45例.实验组采用ABC技术在CT引导下进行穿刺活检,对照组不采用ABC技术在CT引导下进行穿刺活检,比较2组穿刺活检的成功率、术中时间、初次进针准确率、调针次数及并发症发生率.结果实验组穿刺成功率为100%(25/25),术中时间(12.3±2.6)min,初次进针准确率40%(10/25),调针次数1.0(0,1.5)次,并发症发生率8%(2/25);对照组穿刺成功率为98%(44/45),术中时间(14.3±3.2)min,初次进针准确率16%(7/45),调针次数1.0(1.0,2.0)次,并发症发生率29%(13/45).在穿刺活检的成功率方面2组间差异无统计学意义(P>0.05);在术中时间、初次进针准确率、调针次数和并发症发生率方面2组间差异有统计学意义(P<0.05).结论ABC技术应用于CT引导下肺部小结节穿刺活检能有效地提高初次进针准确率、减少调针次数、减少穿刺术中时间、降低并发症发生率、降低穿刺活检手术风险,值得临床推广.Objective To probe the application value of active breathing control(ABC)technique in CT-guided puncture biopsy of small pulmonary nodules.Methods 70 patients with small pulmonary nodules(≤2 cm)were selected for puncture biopsy.There were 25 cases for the experimental group with ABC technique,and other 45 cases for the control group without the technique.The success rate,intraoperative time,accuracy rate of the first injection,frequency of needle adjustment and incidence of complications were compared between the two groups.Results For the experimental group,the success rate of puncture was 100%(25/25),while.98%(44/45)for the control group.And the intraoperative time,accuracy rate of the first injection,frequency of needle adjustment and incidence of complication were(12.3±2.6)min,40%(10/25),1.0(0,1.5)and 8%(2/25)respectively in experiment group,while(14.3±3.2)min,16%(7/45),1.0(1.0,2.0),29%(13/45)respectively in the control group.There were significant differences in the intraoperative time,accuracy rate of the first injection,frequency of needle adjustment and incidence of complications(P<0.05)between the two groups,however there was no significant difference in success rate of puncture in our study(P>0.05).Conclusion ABC technique can improve the accuracy rate of the first insertion effectively,and also reduce the frequency of needle adjustment,time of puncture operation,the incidence of complications and the risk of puncture biopsy in CT-guided small pulmonary nodule puncture biopsy,which is worth being used in clinical practice.
