Clinical assessment of the safe use local anaesthesia with vasoconstrictor agents in cardiovascular compromised patients: a systematic review.

The use of vasoconstrictor agents has many advantages, but its use has been limited due to a fear of systemic absorption and the induction of adverse effects in cardiac compromised patients. The aim of this study was to review the literature to assess any scientific basis for the limited use of dental anaesthesia with a vasoconstrictor agent in cardiovascular compromised patients.
