Overview

PurposeAlthough intraoperative anaphylaxis during surgery is a rare event, we describe five patients who experienced perioperative anaphylactic reactions during renal transplantation and were referred for investigation.Clinical featuresSkin-prick and intradermal skin tests were done to investigate potential allergies to drugs given perioperatively prior to the development of anaphylaxis, including basiliximab, propofol, cefazolin, cis-atracurium, fentanyl, latex, remifentanil, and chlorhexidine. In addition, in vitro serologic testing for specific IgE was done in patients suspected to have had chlorhexidine anaphylaxis. All five patients were male, with a mean age of 48 yr (range 30–69). Skin testing for all drugs was non-reactive except for chlorhexidine, which was positive in four of five patients (one patient refused intradermal testing). In vitro test results for chlorhexidine-specific IgE were positive in all of the patients. Anesthetic records showed that intraoperative anaphylaxis had occurred immediately after insertion of a chlorhexidine-coated central venous catheter.ConclusionsIntraoperative insertion of chlorhexidine-coated central venous catheters can trigger life-threatening anaphylaxis in susceptible patients undergoing renal transplantation.
