intraoperative anaphylaxis to inj ceftriaxone: here we go again

Anaphylactic reactions to intraoperative antibiotics are rare events and reactions after a negative intradermal skin testing are even rarer. We are reporting a case of grade V anaphylactic reaction to ceftriaxone, which occurred inspite of a negative skin testing preoperatively. Despite of the treatment along the established guidelines, patient suffered hypoxic brain damage ultimately having a fatal outcome 7 days later. This case highlights the limits of the screening test done preoperatively for antibiotic sensitivity and also the difficulty in resuscitating anaphylactic reac-tions when patient is on B blocker and under spinal anaesthesia.
