Abstract

Background & Objectives: Cardiac arrest is an indicator of the quality of medical attention in surgical rooms, currently there are no previous studies regarding this topic in Peru. The objective of this study was to identify mortality risk factors for intraoperative cardiac arrest (ICA) in a high complexity hospital and to determine its incidence and presumptive causes. Materials & Methods: A 5-year cohort study was conducted at Almenara General Hospital, Lima-Peru from 2011 to 2015, including patients who suffered an intraoperative cardiac arrest (ICA). The cause of the ICA was established by consensus of researchers. Descriptive and inferential statistics were used with chi-square test and RR, using SPSS version 21. p < 0,05 were considered significant and values < 0,01 highly significant. Results: From a total of 74 096 patients, 88 patients were found to have suffered ICA, with an incidence of 11,9 per 10 000 surgeries; 22 ICAs occurred due to an anesthetic cause (2,9 per 10 000). The registered mortality due to ICA was 5, 26 per 10 000, and due to anesthesia was 0,52 per 10 000 (4 cases). The prevalence of ICA due to anesthesia was 25%. The risk factors for mortality were: ICA due to surgical or critical patient causes (RR 2,9 IC95% 1,2-7,3), cardiovascular causes (RR 2,2 IC95% 1,5-3,3), highly complex surgeries (RR 1,58 IC95% 1-2,48), ICA during anesthetic maintenance (RR 2 IC95%1,1-3,7), and CPR time longer than 20 minutes (RR 3,9 IC95% 2,4-6,6). An association between mortality and the following parameters was found: age higher than 70 (x2 12, 4 p=0,006), ICA due to surgical or critical patient causes (x2 8, 1 p=0,004), cardiovascular surgery (x2 10, 3 p=0,001), ICA during anesthetic maintenance (x2 6,2 p=0,01) and CPR longer than 20 minutes (x2 32,8 p=0,000).Table 1:: Intraoperative Cardiac Arrest (ICA) and Mortality, Almenara Hospital. Lima, Peru. 2011- 2015Conclusion: In a country with a low human development index as Peru, the incidence of ICA is still high. The anesthetic factor in the ICA is not a determining factor for mortality. The mortality risk factors are related to high surgical complexity, multiple co-morbidities and critical conditions in surgery patients who are treated in our hospital.
