Chlorhexidine impregnated central venous catheter inducing an anaphylatic shock in the intensive care unit.

摘要

Chlorhexidine, a bisbiguanide, is widely used as an antiseptic agent in medical practice as it has the greatest residual antimicrobial activity. Central venous catheters coated extraluminally with chlorhexidine have been made to reduce extraluminal contamination. By using both the chlorhexidine-alchohol skin preparation and antimicrobial-coated catheters during vascular cannulation, it can reduce catheter related bloodstream significantly [1]. The reduction in infection rate is especially vital in critically ill patients who require long-term vascular access. Adverse reactions to chlorhexidine are rare and uncommon, and have been under-recognised as a cause of anaphylaxis. There are several reports of allergic reactions following exposure to chlorhexidine. We report of a case of anaphylaxis shock requiring cardiopulmonary resuscitation during the placement of a chlorhexidine impregnated central venous catheters.
