Réaction anaphylactique liée au latex probablement transmis par le greffon au cours d'une transplantation rénale

Latex anaphylaxis in a recipient child during kidney transplant performed in a latex-free environment: case report

Latex responds for most allergic reactions in children, and repeated exposure to the agent is the main cause of sensitization. We report the case of a child allergic to latex who developed anaphylaxis during kidney transplantation performed in a latex-free environment. After immediate treatment with epinephrine the patient gradually improved. Subsequent investigation revealed that kidney harvesting was performed without latex allergy precautions, suggesting graft contamination by the antigen. We conclude that, for preventing this type of anaphylaxis, it is essential to implement latex-free procedures during donor organ harvesting.

Anesthetic management of donor nephrectomy for a recipient with history of malignant hyperthermia: avoiding a transferred trigger

We describe a case of living unrelated renal transplantation from a non-malignant hyperthermia (MH) susceptible donor to an MH-susceptible recipient, along with its intraoperative and perioperative considerations. The renal transplant recipient reported a personal history of MH requiring intensive care unit admission. A nontriggering anesthetic was therefore chosen for the unrelated donor to avoid possible triggering via the transplanted kidney to the MH-susceptible recipient. This case provides a unique opportunity to review the concepts of antigen transfer related to transplant anesthesia, as well as the importance of communication among anesthesia and surgical teams to promote patient safety.

Anaphylaxis during renal transplantation of live donor graft in a child with latex allergy: case report

BACKGROUND AND OBJECTIVES

Latex allergy is becoming increasingly more frequent, affecting patients and health care professionals. The objective of this report was to present the case of a child with allergy to latex, who developed anaphylaxis during anesthesia for renal transplantation, and emphasize some of the multidisciplinary conducts used to decrease the risk of anaphylactic shock after graft reperfusion.

CASE REPORT

A male child, 5 years and 10 months old, P3 by the ASA classification, with a history of allergy to latex diagnosed after contact with balloons and confirmed by Rast test specific for latex and Prick test, underwent renal transplantation of a live donor graft for end-stage renal disease secondary to urologic malformation. The protocols for patients with Latex Allergy adopted by the Anesthesiology and Nursing Departments of the Hospital das Clínicas da UNICAMP were observed to avoid exposure of the child to latex. They started the day before the surgery by cleaning the operating rooms and substituting of all medical-hospital products by latex-free material. The equipment and materials used during the procedure were latex-free according to a technical report provided by the manufacturers. The surgery was done under general anesthesia and controlled mechanical ventilation. At the end of the surgery, the patient required blood transfusion, which was administered by a pressurizer; he developed cutaneous rash and the blood transfusion was discontinued, hydrocortisone was administered, and the infusion of crystalloids was increased. The child had an immediate and satisfactory response to the treatment.

CONCLUSIONS

Latex allergy has become a public health problem and the knowledge of specific therapeutic conducts allows immediate treatment and decreases patient risks.
