Abstract

Objective of the study is to present the analysis of performance of emergency diagnostic ultrasound services in the division of resuscitation and intensive therapy of cardiovascular surgery clinic that provides technologically advanced care, and to determine the possibilities to use the standards of diagnostic ultrasound examination in intensive care in patients who underwent surgery for ischemic heart disease and post-infarction left ventricular aneurysm. Material and methods. The study included 102 patients with coronary artery disease and post-infarction left ventricular aneurysm who underwent myocardial revascularization and left ventricular geometry reconstruction by endoventricular circular patch plasty repair. Majority of patients had a smooth post-operative course – they were included in group I, group II was composed of 12 patients with complicated course. Results. Echocardiographic indices of the functional state of the left ventricular myocardium in an early post-operative period in group I patients indicated an adequate myocardial response to the surgical correction performed and appeared to be the favourable prognostic factors. Breakdown of adaptive processes and compensatory mechanisms of left ventricular myocardium was observed in group II patients in an early post-operative period, that was characterized by a number of echocardiographic parameters. Patients who had a smooth post-operative course stayed in Resuscitation and Intensive Care Unit within 24 to 48 hours and two diagnostic ultrasound procedures on average – echocardiography and ultrasound examination of the pleura were performed on each patient daily. Patients with complicated course in Resuscitation and Intensive Care Unit had more than two ultrasound examinations, the total number of ultrasound scans performed per one patient ranged from 20 to 40. The largest number of ultrasound examinations were performed on 3d–9th post-operative day, the rate of further ultrasound monitoring didn't exceed 2 scans per day. Conclusion. Diagnostic ultrasound standards for patients who have a smooth early post-operative course must include focused echocardiography and ultrasound examination of pleural cavities – before surgery and before transfer from the Resuscitation and Intensive Care Unit. Additional ultrasound protocols of organs and body systems must be used for patients who have complicated early post-operative course and multiple organ dysfunction syndrome depending on the form of pathology developed. All patients with congestive heart failure must undergo clinically indicated extended and repeated echocardiographic examination which enables a detailed dynamic assessment of the functional state of the heart and circulatory system taken as a whole.
