心律失常是常见的术中合并症。然而,麻醉中发生病态窦房结综合症却比较少见。作者遇到一例,报道如下:患者,女,62岁,诊断为直肠癌而行手术治疗。术前血压124/50毫米汞柱,心率82次/分。胸透和心电图均无异常。血尿常规,肝、肾功能、电解质等均正常。在丙烯硫贲妥钠,司可林诱导下气管插管,以笑气—氧—氟烷维持麻醉,用泮侃朗宁维持肌肉松弛下进行手术。在麻醉诱导后10分钟,出现血压下降和心动过缓(52次/分),经静注阿托品后好转,但一小时后又出现上述情况,再次静注阿托品后,血压和心率虽然恢复正常,但有心律失常,经心电图监测,证实有窦房阻滞。停用氟烷并静注异丙基肾上腺素,
Arrhythmia is a common intraoperative complication. However, the occurrence of sick sinus syndrome in anesthesia is relatively rare. The author encountered a case, the report is as follows: Patients, female, 62 years old, diagnosed with rectal cancer surgery. Preoperative blood pressure 124/50 mm Hg, heart rate 82 beats / min. Thoracic and ECG were normal. Hematuria, liver, kidney function, electrolyte, etc. are normal. In the propylene thiophanate sodium, sclerotin-induced endotracheal intubation, to niacin - oxy-halothane to maintain anesthesia, with Pan Kan Lang Ning to maintain muscle relaxation surgery. 10 minutes after induction of anesthesia, blood pressure and bradycardia (52 beats / min), improved after intravenous atropine, but one hour later appeared again, after intravenous atropine, although the blood pressure and heart rate returned to normal, However, arrhythmia, ECG monitoring, confirmed sinoatrial block. Discontinue halothane and intravenous isoproterenol,
