简介:摘要:在盖梁施工中,抱箍法是一种常用方法,有比较多的技术应用优势,例如施工工艺比较简单、整体性能较为理想、对空间的占用比较少等等。本文与工程实例相结合,对不良地质条件下抱箍法盖梁的施工进行分析,可以为类似工程提供相应的参考。

简介:摘要目的探讨膀胱挤压排尿法用于处理椎管麻醉术后尿潴留的临床应用效果。方法选取实施椎管麻醉法行下肢手术术后尿潴留的患者90例,随机均分为两组,每组45例。对照组采用传统诱导排尿法,观察组采用膀胱挤压排尿法帮助其排尿。观察两组患者排尿缓解/解除情况以及首次排尿时间。结果观察组患者排尿缓解/解除有效率为93.33%,对照组为62.22%,差异具有统计学意义(P<0.05);与对照组相比较,观察组患者40min内首次排尿时间的患者例数明显多于对照组(P<0.05)。结论传统排尿法和膀胱挤压排尿法均可应用于改善椎管麻醉术后患者的尿潴留情况,相比而言,膀胱挤压排尿法缓解/解除椎管麻醉术后患者的尿潴留的患者的尿潴留情况更有效,临床疗效显著,值得进一步推广应用。
