【摘要】 目的:探讨在经皮肺穿刺活检术中应用生理盐水预防气胸发生的效果。方法:经皮肺穿刺活检病例136例,其中年龄<55岁36例,年龄>55岁100例(随机分成A、B两组,各50例),其中B组在经皮肺穿刺活检术中经穿刺针注射生理盐水。结果:136例均穿刺成功,并发气胸的情况:年龄<55岁组发生气胸2例,气胸量<10%。年龄大于55岁的气胸发生率较高,A组发生气胸14例,其中12例气胸量<10%、2例>30%,有皮下气肿1例;B组发生气胸4例,气胸量均<10%。B组的气胸发生率明显低于A组,B组无1例因注射生理盐水而出现咳嗽、咳痰等不适。结论:经皮肺穿刺活检术中注射生理盐水可在一定程度上堵塞穿刺针穿刺肺胸膜的针孔道,减少气胸的发生率。更多还原

【Abstract】 Objective:To investigate the effect of using normal saline (NS) injection to prevent pneumothorax in percutaneous needle biopsy of lung.Methods:136 patients (<55 years of age,n=36;>55 years of age,n=100) having percutaneous needle biopsy were divided into two groups (group A,Group B),with 50 patients in each group.NS was injected via the needle during the percutancous needle biopsy operation in Group B.Results:Of the 136 patients,percutaneous needle biopsy of lung were successfully performed.2 cases in patients with the age <55 years of age had complicated pneumothorax,with the volume of gas <10%.Of the patients with the age >55 years,pneumothorax were seen more commonly.14 cases in Group A were complicated with pneumothorax,12 patients had the volume <10% and 2 patients >30%,subcutaneous emphysema was seen in 1 patient.Of the Group B,only 4 patients had pneumothorax with the volume <10%,the incidence rate of pneumothorax was obviously lower than that of Group A,morbidity including cough or expectoration was not occurred due to injection of NS.Conclusion:Injection of NS during percutaneous needle biopsy of lung can block the puncture pathway of visceral pleura in certain degree,and reduce the incidence rate of pneumothorax.更多还原
