对1例肺动脉高压患者行桡动脉穿刺致肺动脉高压危象发生的原因进行了分析,认为桡动脉穿刺时的疼痛及穴位刺激会使肺血管收缩而导致危象的发生。今后对于动脉压与体循环血压比值(PAP/SBP)≥0.5的患者,应慎重进行桡动脉穿刺。
The causes of pulmonary hypertension crisis in patients with pulmonary hypertension underwent radial artery puncture were analyzed. It is concluded that the pain and acupoint stimulation during radial artery puncture lead to the contraction of the pulmonary vasoconstriction, which leads to the crisis. In the future for arterial pressure and systemic blood pressure ratio (PAP / SBP) ≥ 0.5 patients should be carefully carried out radial artery puncture.
