颅内病变引起心电图异常相当多见,包括ST段改变,U波和不同程度的心脏阻滞。颅内压升高常出现心动过缓,但低颅压导致节律变化则不多见。作者报道一例70岁男性,右前额叶脑膜瘤局灶性运动发作的病人,住院后用地塞米松4mg每12h一次,苯妥英钠300mg每晚一次,既往无心血管疾患,心电图亦正常。入手术室后血压130/80mmHg,心率80bpm,呼吸16bpm,神智清楚定向良好。静注硫贲妥钠3mg/kg,芬太尼7μg/kg,维库溴铵0.1mg/kg,气管插管,吸入70％N_2O-O_2-0.5％～1.0％异氟醚,腰穿抽吸脑脊
Electrocardiographic abnormalities caused by intracranial lesions are quite common, including ST segment changes, U waves and varying degrees of cardiac arrest. Intracranial pressure often appears bradycardia, but low intracranial pressure leads to rhythm changes are rare. The authors report a 70-year-old man with focal locomotor activity on the right frontal lobe meningioma who was hospitalized with dexamethasone 4 mg every 12 hours and phenytoin 300 mg once night, with no previous cardiovascular disease and normal ECG. Into the operating room after the blood pressure 130 / 80mmHg, heart rate 80bpm, breathing 16bpm, God clearly well oriented. Intravenous injection of thiopental sodium 3mg / kg, fentanyl 7μg / kg, vecuronium 0.1mg / kg, endotracheal intubation, inhalation of 70% N2O2O_20.5% to 1.0% isoflurane, lumbar puncture suction Cerebrum
