ABSTRACT

BACKGROUND: To analyze the indications, actions and results of the operations performed in the Cardiovascular Surgery Intensive Care Unit. METHODS: Retrospective analysis of consecutive non-selected adult patients operated in the ICU. All operations were included. Descriptive statistics were used. RESULTS: Between 2008 and 2013, 3379 consecutive adult patients were operated upon. A total of 124 operations were performed in the ICU in 109 patients, 70 male (64.2%) and 39 female (35.8%) with a mean age of 61.6 years (12-80). This represented 3.2% of all operations. During the study period, 185 patients (5.5%) were reoperated for postoperative bleeding/tamponade in the operating room. The index interventions were for valvular heart disease (34.9%), aortic disease (22.9%), ischemic heart disease (15.6%), combined valvular/ischemic (12%), valvular/aorta (11%) and miscellaneous (3.6%). The indications for reoperation were persistent bleeding 54 (43.5%), pericardial tamponade 41 (33%), low cardiac output 13 (10.5%), cardiac arrest/arrhythmia 8 (6.5%), respiratory insufficiency 6 (4.8%) and acute ischemic limb 2 (1.7%). Operations performed were mediastinal exploration 73 (58.9%), implant/removal of ECMO 17 (13.7%), sternal closure 16 (12.9%), open resuscitation 9 (7.3%), subxyphoid drainage 7 (5.6%) and femoral embolectomy 2 (1.6%). Overall mortality was 33%. There was one case of mediastinitis (0,9%), with no difference from patients operated in the regular operating room. CONCLUSIONS: Operations in the ICU represent a safe, life-saving alternative in specific subgroups of patients. The risk of wound infection is not increased, unstable patients are not transferred and there is time savings.
