简介:通讯作者张琦(1974.10-),本科,主管护师,吉林大学第一医院ICU。摘要目的研究重度心衰所致四肢高度浮肿患者长期静脉输注药物的有效途径,寻求使药物达到最佳疗效的方法。方法对40例重度心衰所致四肢高度浮肿患者随机分为两组,试验组(n=20)采取PICC建立静脉通路;对照组(n=20)采取传统四肢外周静脉建立静脉通路。观察药物达到疗效所用时间以及住院时间。结果试验组除1例死亡外,其余19例均治疗好转出院,平均住院天数(8)天。对照组死亡3例,放弃治疗1例,其余16例治疗好转出院,平均住院天数12天。结论PICC能够最大程度上使药物进行有效循环,并且能够在最短时间内使药物发挥作用,同时减少了患者反复静脉穿刺的痛苦。

简介:目的探讨斑点追踪技术(STI)对乳腺癌化疗前后左心室局部收缩功能的评价。方法应用STI检测乳腺癌术后化疗患者左室短轴切面,乳头肌水平的前间壁、后壁的应变曲线,分析并计算左心室局部收缩功能,并与健康对照组进行比较分析。结果①对照组乳头肌水平切面前间壁平均心肌运动速率(MV)、环向应变率(CSR)、径向应变率(RSR)、角速度(AV)、角位移(AE)分别为(2.745±0.330)cm/s、(1.265±0.330)s-1、(1.462±0.460)s-1、(51.224±0.420)°/s和(2.598±0.330)°,化疗组分别为(1.282±0.300)cm/s、(0.271±0.290)S-I、(0.319±0.280)s-1、(25.812±0.290)o/s和(O.339±0.270)°;对照组乳头肌水平切面后壁平均MV、CSR、RSR、AV、AE分别为(2.504±O.240)cm/s、(1.149±0.360)s-1、(1.234±0.210)s-1、(25.998±0.310)°/s和(0.976±0.340)-1,化疗组分别为(1.133±0.280)cm/s、(0.359±0.300)s-1、(0.179±0.220)s-1、(10.915±0.210)。/s和(0.212±0.270)。。与对照组比较,化疗组乳头肌水平切面前间壁、后壁的MV、CSR、RSR、AV、AE均减低,差异具有统计学意义(P〈0.05)。②对照组平均左室射血分数(LVEF)、收缩末期左室内径(LVDd)、收缩末期室间隔厚度(IvsTd)、收缩末期左室后壁厚度(LVPwTd)分别为(65.12±1.45)%、(41.53±2.45)mm、(7.71±0.42)mm和(7.61±0.32)mm,化疗组分别为(63.87±1.03)%、(40.56±2.16)mm、(8.44±0.67)mm和(8.29±0.61)mm,两组比较差异无统计学意义(P〉0.05)。结论斑点追踪技术能够早期、准确地评价乳腺癌化疗前后左室局部收缩功能,为临床早期治疗及预后判断提供有价值的信息。
