The authors report a case of hypertensive emergency (defined as systolic blood pressure >180 mm Hg and diastolic blood pressure >110 mm Hg with end organ damage) following brachial plexus blockade in a hypertensive lady with unstable angina. The authors describe blocking of baroreceptor reflexes by the local anaesthetic as a putative mechanism and suggest that this potentially serious complication should be considered when planning this particular anaesthetic technique.
作者报告了一例在一位患有不稳定型心绞痛的高血压女性患者进行臂丛神经阻滞后发生高血压急症(定义为收缩压>180 mmHg且舒张压>110 mmHg并伴有终末器官损害)的病例。作者将局部麻醉药对压力感受器反射的阻断描述为一种可能的机制,并建议在计划采用这种特定麻醉技术时应考虑到这种潜在的严重并发症。
