ObjectivesThe aim of this study is to analyze the cardiac arrests related to anesthesia in a tertiary children's hospital, in order to identify risk factors that would lead to opportunities for improvement.MethodsA 5-year retrospective study was conducted on anesthesia related cardiac arrest occurring in pediatric patients. All urgent and elective anesthetic procedures performed by anesthesiologists were included. Data collected included patient characteristics, the procedure, the probable cause, and outcome of the cardiac arrest. Odds ratio was calculated by univariate analysis to determine the clinical factors associated with cardiac arrest and mortality.ResultsThere were a total of 15 cardiac arrests related to anesthesia in 43,391 anesthetic procedures (3.4 per 10,000), with an incidence in children with ASA I-II versus ASA≥III of 0.28 and 19.27 per 10,000, respectively. The main risk factors were children ASA≥III (P<.001), less than one month old (P<.001), less than one year old (P<.001), emergency procedures (P<.01), cardiac procedures (P<.001) and procedures performed in the catheterization laboratory (P<.05). The main causes of cardiac arrest were cardiovascular (53.3%), mainly due to hypovolemia, and cardiovascular depression associated with induction of anesthesia, followed by respiratory causes (20%), and medication causes (20%). The incidence of mortality and neurological injury within the first 24h after the cardiac arrest was 0.92 and 1.38 per 10,000, respectively. The mortality in the first 3 months was 1.6 per 10,000. The main causes of death were ASA≥III, age under one year, pulmonary arterial hypertension, cardiac arrest in areas remote from the surgery area, a duration of cardiopulmonary resuscitation over 20min, and when hypothermia was not applied after cardiac arrest.ConclusionThe main risk factors for cardiac arrest were ASA≥III, age under one year, emergency procedures, cardiology procedures and procedures performed in the catheterization laboratory. The main cause of the cardiac arrest was due mainly to cardiovascular hypovolemia. All patients who died or had neurological injury were ASA≥III. Pulmonary arterial hypertension is a risk of anesthesia-related mortality.Copyright © 2012 Sociedad Española de Anestesiología, Reanimación y Terapéutica del Dolor. Published by Elsevier España.
