When obtaining consent for internal jugular central venous line placement, the following might be discussed as potential complications, EXCEPT:
a) Central-line associated blood stream infection
b) Vascular injury
c) Mydriasis
d) Anhidrosis
e) Pneumothorax
Answer c. While risks associated with internal jugular line placement often focus on the risks of arterial puncture, venous thrombosis, blood stream infections, and pneumothorax, injury to the sympathetic chain can lead to Horner’s syndrome. Horner’s Syndrome is a constellation of symptoms including the lack of sweating on the ipsilateral face (anhidrosis), upper lid (more common than lower lid) ptosis, ipsilateral pupillary constriction (miosis), and the appearance of a sunken eye (enophthalmos).
