In a patient with a solitary pheochromocytoma severe hypoglycemia developed following excision of the tumour. The possible causative mechanism was thought to be a reactive relative increase in insulin production secondary to increased endogenous production of glucose, induced by the large amounts of epinephrine produced by the tumour. Alternatively, epinephrine withdrawal following removal of the tumour under phentolamine infusion may have induced increased insulin production and hence potentiated the development of hypoglycemia. Careful monitoring of the blood glucose concentration during and after the operation is recommended to obviate this potentially fatal complication.
在一名患有孤立性嗜铬细胞瘤的患者中,肿瘤切除后出现了严重低血糖。可能的致病机制被认为是肿瘤产生的大量肾上腺素诱导内源性葡萄糖生成增加,继而导致胰岛素分泌反应性相对增加。另外,在酚妥拉明输注下切除肿瘤后肾上腺素撤离,可能诱导胰岛素分泌增加,从而加剧了低血糖的发生。建议在手术期间及术后仔细监测血糖浓度,以避免这种潜在的致命并发症。
