METHODS: An 81-year-old Japanese man was scheduled to undergo transurethral resection of bladder tumor. The patient took 5-aminolevulinic acid orally 2 hours before entering the operating room. After the induction of anesthesia, his blood pressure decreased to 47/33 mmHg. The patient\'s hypotension did not improve even after noradrenaline was administered. After awakening from anesthesia, the patient\'s systolic blood pressure increased to approximately 100 mmHg, but approximately 5 hours after returning to the ward, cardiac arrest occurred for approximately 12 seconds.
CONCLUSIONS: We experienced a case of postoperative cardiac arrest in a patient, probably owing to the use of 5-aminolevulinic acid. Although the cause of cardiac arrest is unknown, perioperative hemodynamic management must be carefully performed in patients taking 5-aminolevulinic acid.
方法:一名81岁的日本男子计划接受经尿道膀胱肿瘤切除术。患者在进入手术室前2小时口服5-氨基乙酰丙酸。麻醉诱导后,他的血压下降到47/33mmHg。即使服用去甲肾上腺素,患者的低血压也没有改善。麻醉苏醒后,患者的收缩压升高到约100mmHg,但回到病房大约5小时后,心脏骤停发生约12秒.
结论:我们经历了一例患者术后心脏骤停,可能是由于使用了5-氨基乙酰丙酸。虽然心脏骤停的原因不明,对于服用5-氨基乙酰丙酸的患者,必须谨慎进行围手术期的血流动力学管理.
