病人在危重情况下发生阵发性室上性心动过速,ICU 的护士应学会使用腺苷(Adenosine)。作者报道一例病人63岁,男性,因消化道出血收入ICU 救治。病人有高血压、慢性阻塞性肺病和慢性肾功能不全病史.经内窥镜检查为十二指肠溃疡出血,剖腹探查实施了十二指肠后壁溃疡缝合、迷走神经切断和幽门成形术。术后第3天出现原因不明的心动过速(心率110～120次/分)。术后第5天,突然阵发性室上性心动过速(心率150～170次/分),经颈动脉按压,静注异搏定10mg 无效。即快速静注腺苷6mg,转复为窦性心律。术后第8天,又有一类似发作,经颈动脉按压、静注异 Patients with paroxysmal supraventricular tachycardia in critical conditions, ICU nurses should learn to use adenosine (Adenosine). The author reported a 63-year-old man with ICU treatment for gastrointestinal bleeding. The patient had a history of hypertension, chronic obstructive pulmonary disease and chronic renal insufficiency, bleeding from duodenal ulcer by endoscopy, laminectomy for posterior duodenal wall, vagotomy and pyloroplasty. Unidentified tachycardia (heart rate 110 ~ 120 beats / min) appeared on the 3rd postoperative day. On the fifth postoperative day, a sudden paroxysmal supraventricular tachycardia (heart rate 150 to 170 beats / min) was administered via the carotid artery, and intravenous verapamil 10 mg was ineffective. Rapid intravenous injection of adenosine 6mg, converted to sinus rhythm. On the 8th day after surgery, another similar attack occurred. The carotid artery was pressed and the intravenous injection was different
