Latex sensitization in general pediatric surgical patients: A call for increased screening of patients

Abstract

Background/Purpose: Latex sensitization is a well-documented occurrence in children with myelodysplastic and urologic anomalies. The incidence of latex allergy in general pediatric surgical patients, however, has not been previously addressed. The purpose of this study was to examine the risk of perioperative latex reactions in a general pediatric surgical practice over a 1-year period. Methods: This study examined the occurrence of latex sensitization using two methods. First, the preoperative anesthesia records of patients that have undergone surgery from October 1995 through September 1996 at Mott Children's Hospital were reviewed retrospectively. Second, all patients who had intraoperative anaphylaxis attributable to latex sensitization, including those from three additional hospitals, were evaluated. Results: During a 12-month period, 1,523 pediatric general surgical operations were performed at the C.S. Mott Children's Hospital. Of these, only 11 operations on five patients were performed under latex precautions. All of these patients had a preoperative diagnosis of latex sensitivity. During the same period, intraoperative anaphylactic reactions caused by latex allergy occurred in two of the general surgical patients (0.13%) at the C.S. Mott Hospital. Four additional cases are also reported from other study hospitals. None of these patients were suspected, based on current screening methods, of having a latex allergy before their surgery. Conclusions: Latex allergy is a potentially life-threatening condition in the pediatric general surgical population. Further study is needed to develop criteria to preoperatively identify patients at risk for latex sensitization.
