| pubmed-article:2884906 | pubmed:abstractText | Two cases are reported, demonstrating the difficulty to verify the lack of inadvertent intravascular injection of local anaesthetic during epidural anaesthesia in patients under beta-blockers. The tachycardia usually elicited by intravascular injection of a local anaesthetic-adrenaline mixture does not occur in these patients. The alternative consists in measuring blood pressure at the second minute after a test injection. | lld:pubmed |
