[A possible hypersensitivity reaction to total parenteral nutrition]

We present a possible case of a hypersensitivity reaction to parenteral nutrition in a surgical patient of 61 years, weighing 49 kg, who presented facial, thoracic, and underarm erythema, proximal to the peripheral line, accompanied by pruritus: the symptoms disappeared after discontinuing the nutrition and after administration of dexchlorpheniramine. Analysis of the possible causes of this manifestation takes place, as well as of the components of the parenteral nutrition, route of administration, and concomitant medication.
