Introduction Neuroblastoma is the most common extracranial pediatric tumor, accounting for 5–8% of all childhood cancers. Neuroblastomas arise from catecholamine‐secreting neural crest cells and their metabolites, vanillylmandelic acid and homovanillic acid, that are readily detected in urine. Although rarely seen in clinical practice, case reports exist documenting severe intraoperative hypertension. However, data on the incidence of intraoperative hypertension are lacking. Methods This report is a single‐center retrospective review of patients with neuroblastoma who underwent surgical resection (n = 102) at Boston Children's Hospital from July 1, 2012 to February 28, 2021. Significant intraoperative hypertension was defined as maximum systolic blood pressure greater than 95th percentile +12 mmHg based on normative blood pressure data. Statistical analysis was performed using Fisher's exact test, Wilcoxon rank‐sum test, and logistic regression. Results The overall incidence of intraoperative hypertension was 13% (n = 13/102). Higher American Society of Anesthesiologists (ASA) physical status was associated with intraoperative hypertension. Antihypertensive medications were administered intraoperatively in 9% of cases (n = 9), and the use was significantly associated with intraoperative hypertension. Of patients with preoperative urine catecholamine data (n = 82), all 10 patients who had intraoperative hypertension were noted to have elevated preoperative urine catecholamines. Intraoperative hypertension was not associated with postoperative hypertension, postoperative hypotension, or increased intensive care unit length of stay. Discussion/Conclusion Intraoperative hypertension in patients with neuroblastoma remains a relatively uncommon occurrence; however, it does occur at a frequency higher than previously described. While intraoperative hypertension is associated with an increased use of antihypertensive medications in the operating room, it is not associated with adverse perioperative outcomes.
