Summary The haemodynamic problems associated with anaesthesia and neuroblastoma were reviewed in 52 children who underwent 138 operations at The Hospital for Sick Children, London, UK. At diagnosis 42 patients (81%) had elevated urinary catecholamine metabolites; nine (17%) were hypertensive, of whom eight were treated with adrenergic blockade. The incidence of intra‐operative hypertension due to excess catecholamine release was 9% (13/138), and was confined to the group undergoing tumour excision (29%; 13/45). Hypertension was observed more frequently in patients who had not received chemotherapy. It was effectively controlled by labetalol. Patients symptomatic of catecholamine secretion before surgery should be managed in a similar manner for those with a phaeochromocytoma. Surgical manipulation of the tumour predisposes to paroxysmal hypertension. Careful monitoring is advised.
