Impact of Minimally Invasive Approach on Pulmonary Function in Patients Undergoing Aortic Valve Replacement
Gofus, Ján ; Pojar, Marek (advisor) ; Rohn, Vilém (referee) ; Šantavý, Petr (referee)
of the dissertation Impact of minimally invasive approach on pulmonary function in patients undergoing aortic valve replacement MUDr. Ján Gofus The most common minimally invasive approach to aortic valve replacement is upper hemisternotomy, which has been implemented at our department, as well. Preserving the lower half of thoracic cage could lead to lower postoperative drop of pulmonary function, apart from other benefits. Nevertheless, publications on this topic are insufficient and controversial. Our aim was to perform a prospective randomized trial comparing upper hemisternotomy with standard (median) sternotomy in terms of pulmonary function changes perioperatively. We also added a novel exercise tolerance test, one-minute sit-to-stand test, and a quality of life evaluation to the study. We included patients indicated for elective isolated aortic valve replacement with bioprosthesis who were older than 65 years, signed informed consent, and in which both surgical approaches were technically feasible. Exclusion criteria were re-do surgery and concomitant cardiac surgery. Patients were randomized to minimally invasive and standard group in 1:1 ratio. On the day of admission, on the 7th postoperative day and 3 months postoperatively, the patients underwent pulmonary function testing and one-minute...

The Role of a Nurse and Specific Nursing Care for Minimal Invasive Cardiac Surgery Procedures
BENDOVÁ, Miroslava
The overall development of scientific and technical disciplines has enabled the introduction of minimally invasive surgical techniques in cardiac surgery practice. Implementation of minimally invasive cardiac surgery brings many positive effects for patients and healthcare. At the same time, however, it requires for the nurses to have appropriate knowledge, skills and experience to effectively provide comprehensive nursing care. The thesis is divided into theoretical and empirical parts. A total of four objectives were set. The first goal determines the specifics of nursing care of the patient before and after minimally invasive cardiac surgery. The second mapping the differences in nursing care in minimally invasive cardiac surgery from heart surgery classical approach. The third objective determines the role of nurses in patient awareness of minimally-invasive cardiac surgery. The fourth objective is focused on the needs and feelings of patients undergoing minimally invasive cardiac surgery. The results of qualitative research showed that preoperative and postoperative nursing care for minimally invasive cardiac surgery is similar to nursing care before and after cardiac surgery by standard median sternotomy approach. Nurses often wipe away differences associated with nursing care of standard and minimally invasive surgery, differences arose mainly after analysis of the data obtained. The differences include shorter hospital stay, shorter duration of mechanical ventilation, lower incidence of postoperative confusion, differences in invasive inputs, rehabilitation and awareness. For the majority of respondents from the ranks of the patients minimally invasive heart surgery technique had clearly positive impact on their mental condition.
