Beta-阻斷劑 (beta-blocker) 透過阻斷交感神經受體來降低血壓與心率。然而,非選擇性 beta-阻斷劑可能阻斷肺部的 beta-2 受體,導致支氣管收縮。對於有氣喘或阻塞性肺病史的病人,這可能引發嚴重的呼吸困難,新出現的喘鳴聲 (wheezing) 是嚴重不良反應的徵兆,必須立即處理。
New-onset wheezing is a priority finding to report because beta-blockers can cause bronchoconstriction, particularly in non-selective formulations, potentially triggering severe respiratory distress. While fatigue and stable vital signs like a heart rate of 70 bpm or blood pressure of 130/85 mmHg are expected or manageable, respiratory compromise indicates a serious adverse reaction requiring immediate medical intervention.
