[Complications of pediatric anesthesia. Survey carried out by the Study Group SIAARTI for anesthesia and intensive therapy in children].

This study was designed to asses in a prospective survey the intra and post-operative adverse outcome of paediatric patients in Italy. The data was carried out in representative samples of anaesthetics performed in different Italian Institutions, which were chosen by the National Study Group for Paediatric Anaesthesia, and included: paediatric, general, specialistic hospitals and departments. A total of 9289 anaesthetics were collected and studied. The mean age of the patients was 62.5 months. In the 320 cases (3.4%) 299 minor (3.2%) and 21 major (0.2%) complications occurred during or within 24 hours of surgery and anaesthesia. Seven of the major complications resulted in the exitus of the patients (0.07%). Fifty percent of the accidents regarded respiratory and twenty percent cardiovascular systems. The major incidence (risk factors) of the minor complications was present in patients less than 6 months, ASA group 2-3-4, emergency surgery, patients with associated pathology, long duration of anaesthesia and high risk operations. The incidence of the major complications appears closely related to: patients age and clinical assessment, weight, ASA group, kind of the operation, indications and durations of the surgery, while in the exitus group the major risk factor is the preoperative pathology, surgical procedures, and then: age, weight, ASA and finally surgery.
