不同型号静脉留置针对右心声学造影阳性率及左心腔显影分级的影响

Influence of different types of venous indwelling on the positive rate of right heart contrast echocardiography and the imaging grade of left heart chamber

目的探讨不同型号静脉留置针对右心声学造影阳性率及左心腔显影分级的影响。方法选取2021年1月至2022年1月于中国人民解放军北部战区总医院行右心声学造影的248例患者作为研究对象,根据随机数字表法分为对照组与观察组,每组124例。对照组在右心声学造影中应用24G密闭式Y型静脉留置针,观察组应用22G密闭式Y型静脉留置针,比较两组在平静呼吸下及行Valsalva动作后左心腔显影分级情况和总阳性率。结果平静呼吸下,观察组左心腔显影分级优于对照组,差异有统计学意义(P<0.05)。在行Valsalva动作后,观察组左心腔显影分级优于对照组,差异有统计学意义(P<0.05)。观察组在平静呼吸下及Valsalva动作后总阳性率均高于对照组,差异有统计学意义(P<0.05)。结论在右心声学造影检查中采用22G密闭式Y型静脉留置针可显著提高右心声学造影阳性率,左心腔显影分级更准确,可为临床介入手术提供参考资料,又能减轻反复检查给患者带来的痛苦及经济负担,减轻患者的心理压力,值得临床推广应用。

Objective To investigate the effect of different types of venous indwelling on the positive rate of right heart contrast echocardiography and the imaging grade of left heart chamber.Methods A total of 248 patients who underwent right heart contrast echocardiography in General Hospital of the Northern Theater Command of the Chinese People's Liberation Army from January 1,2021 to January 30,2022 were selected as the research subjects,they were divided into the control group and the observation group according to the random number table method,with 124 cases in each group.The control group was used 24G closed Y-type venous indwelling needle in right heart contrast echocardiography,and the observation group was given 22G closed Y-type venous indwelling needle,the left heart chamber imaging grading and the total positive rate under calm breathing and after performing Valsalva maneuver were compared between the two groups.Results Under calm breathing,the left heart chamber imaging grading in the observation group was better than that in the control group,and the difference was statistically significant(P<0.05).After Valsalva,the left heart chamber imaging grading in the observation group was better than that in the control group,and the difference was statistically significant(P<0.05).The total positive rate in the observation group was higher than that in the control group under calm breathing and after Valsalva exercise,and the differences were statistically significant(P<0.05).Conclusion The use of 22G closed Y-type venous indwelling needle in right heart contrast echocardiography can greatly improve the positive rate of right heart contrast echocardiography,the left heart chamber imaging grading is more accurate,which can provide accurate reference materials for clinical interventional surgery,it can also reduce the pain and economic burden caused by repeated examinations for patient,reduce the patient's psychological stress,it is worthy of clinical promotion and application.
