- Specific questionnaire detects a high incidence of intra-operative hypersensitivity reactions(2018) GARRO, Laila S.; V, Marcelo Aun; SOARES, Iracy Silvia C.; RIBEIRO, Marisa R.; MOTTA, Antonio A.; KALIL, Jorge; CASTELLS, Mariana C.; CARMONA, Maria Jose C.; GIAVINA-BIANCHI, PedroOBJECTIVE: To assess the incidence of intra-operative immediate hypersensitivity reactions and anaphylaxis. METHODS: A cross-sectional observational study was conducted at the Department of Anesthesiology, University of Sao Paulo School of Medicine, Hospital das Clinicas, Sao Paulo, Brazil, from January to December 2010. We developed a specific questionnaire to be completed by anesthesiologists. This tool included questions about hypersensitivity reactions during anesthesia and provided treatments. We included patients with clinical signs compatible with immediate hypersensitivity reactions. Hhypersensitivity reactions were categorized according to severity (grades I-V). American Society of Anesthesiologists physical status classification (ASA 1-6) was analyzed and associated with the severity of hypersensitivity reactions. RESULTS: In 2010, 21,464 surgeries were performed under general anesthesia. Anesthesiologists answered questionnaires on 5,414 procedures (25.2%). Sixty cases of intra-operative hypersensitivity reactions were reported. The majority patients (45, 75%) had hypersensitivity reactions grade I reactions (incidence of 27.9:10,000). Fifteen patients (25%) had grade II, III or IV reactions (intra-operative anaphylaxis) (incidence of 7:10,000). No patients had grade V reactions. Thirty patients (50%) were classified as ASA 1. The frequency of cardiovascular shock was higher in patients classified as ASA 3 than in patients classified as ASA 1 or ASA 2. Epinephrine was administered in 20% of patients with grade III hypersensitivity reactions and in 50% of patients with grade II hypersensitivity reactions. CONCLUSIONS: The majority of patients had hypersensitivity reactions grade I reactions; however, the incidence of intra-operative anaphylaxis was higher than that previously reported in the literature. Patients with ASA 3 had more severe anaphylaxis; however, the use of epinephrine was not prescribed in all of these cases. Allergists and anesthesiologists should implement preventive measures to reduce the occurrence of anaphylaxis.
conferenceObject Incidence of Intraoperative Anaphylaxis in A University General Hospital in Brazil(2013) GARRO, Laila Sabino; CARMONA, Maria Jose Carvalho; SOARES, Iracy Silvia Correa; AUN, Marcelo Vivolo; RIBEIRO, Marisa Rosimeire; RODRIGUES, Adriana Teixeira; KALIL, Jorge; GIAVINA-BIANCHI, Pedro; MOTTA, Antonio AbilioRATIONALE: The epidemiology of intraoperative anaphylaxis is un-known in Brazil. We aimed to evaluate the incidence and clinical features of anaphylaxis during anesthesia in a University General Hospital in Sao Paulo, Brazil. METHODS: A cross-sectional, observational study analyzing data fromvoluntary notification sent by anesthesiologists, about occurrence of intraoperative anaphylaxis during the period between January and December 2010. The diagnostic criteria for anaphylaxis were based onthe World Allergy Organization Guidelines. We analyzed the incidence of intraoperative anaphylaxis, clinical features, severity of anaphylaxis, types of surgical procedures, classification of anesthetic risk (American Society of Anesthesiologists - ASA), culprit agent cited by the anesthesiologist and type of treatment provided. RESULTS: The incidence of intraoperative anaphylaxis was 69:10.000 surgeries. The mean age of patients with anaphylaxis was 36.7 years-old and 57% were women. The most common procedures associated with anaphylaxis were the abdominal non-vascular (17.1%) and urologic (17.1%) surgeries. Skin symptoms were the most prevalent (85.7%) and all patients who presented cardiovascular shock were classified as ASA II (42.9%) or ASA III (57.1%). Epinephrine was used preferentially in anaphylaxis grade 3 (72.7%), while a few patients with anaphylaxis grades 1 and 2 took the drug (2.1% and 16.7, respectively). The most commonly etiologic drugs cited by the anesthesiologists were the neuromuscular blocking agents (22.9%). CONCLUSIONS: Our incidence of intraoperative anaphylaxis was higher than in other studies reported in the literature. These data are a warning signal to encourage measures to reduce the incidence of these severe reactions.
