Abstract:
A patient undergoing anaesthesia for coronary artery bypass surgery developed what was subsequently confirmed to be an anaphylactic reaction to succinylated gelatin (Gelofusine). By virtue of being on cardiopulmonary bypass, rapid detection, quantification and treatment of volume loss (by vasodilatation and extravasation) was possible. The patient required 51 ml/kg of resuscitative fluids in the 15 minutes after onset of anaphylaxis, or 73% of her calculated preoperative blood volume. Alpha-adrenoceptor agonists and vasopressin were required to manage ongoing vasoplegia. This case emphasises the importance of volume resuscitation and vasopressors in the treatment of anaphylaxis.
