Vasovagal Reactions

Vasovagal reflex is a common adverse sequelae of any surgical or invasive procedure. Usual symptoms include lightheadedness, nausea, and sweating.Vasovagal reactions are typically preceded by a painful injection but may occur when the patient sees the needle or smells the sclerosing solution or alcohol skin prep or is injected while standing. Patients with a history of asthma or coronary artery disease are more susceptible to more serious stress-induced problems. A good medical history preoperatively can prepare the phlebologist for this potential reaction.
