多巴胺是治疗循环性休克的一种有效药物,在成人中最严重的副作用是室性节律失常。最近研究发现,在儿童中应用的剂量与成人相同时,未见心律失常发生。作者报告1例流脑婴儿,应用多巴胺时产生了阵发性室上性心动过速(PSVT),这种副作用以前还未曾报导过。病例报告:6个月女婴,患流脑并发DIC,心律齐、心率150次/分,心音正常无杂音,胸透,心电图,心肌酶均正常。入院后1小时血压由120mmHg下降至50mmHg,脉搏无力。立即静脉输入多巴胺10μg/kg/分,未见有明显反应。当总剂量达50mg时,发生PSVT(心率300次/分)压迫迷走神经无效,静脉 Dopamine is an effective drug for the treatment of circulatory shock, the most serious side effect in adults being ventricular arrhythmias. Recent research found no arrhythmia occurred when children were given the same dose as adults. The authors report an infantile meningitis infants who developed paroxysmal supraventricular tachycardia (PSVT) with dopamine, a side effect that has not been previously reported. Case reports: 6-month-old baby girl, suffering from meningitis complicated by DIC, heart rate Qi, heart rate 150 beats / min, normal heart sound without noise, chest X-ray, ECG, myocardial enzymes were normal. One hour after admission, the blood pressure decreased from 120 mmHg to 50 mmHg, and the pulse was weak. Immediate intravenous dopamine 10μg / kg / min, no significant reaction. When the total dose of 50mg, the occurrence of PSVT (heart rate 300 beats / min) compression of the vagus nerve is invalid, the vein
