Item Is there a difference between two different skin disinfection methods in cardiac surgery in terms of isolated pathogens?(2020) Gunday, Murat; Orhan, Atilla; Turan, Hale; Korez, Muslu Kazim; 32683356Introduction: In this study, our aim was to prospectively compare the different methods of patient disinfections with scrubbing + iodine + alcohol, and the povidone iodine disinfection method, which can be described as classical, in terms of the pathogens isolated on skin and during early postoperative complications. Methodology: Eighty patients undergoing a coronary artery bypass operation were included in the study. The patients were divided into two groups: group 1 (n = 48) patients who underwent scrub, iodine, followed by skin disinfection with alcohol, and group 2 (n = 32) who were treated with povidone iodine three times. The samples were immediately sent to the microbiology laboratory. Specimens from the wounds were incubated under aerobic and anaerobic conditions, and isolates were identified using standard microbiological techniques. Results: In samples taken after disinfection in group 1, significantly less reproduction was observed compared to group 2 (p = 0.001). There was no difference in postoperative complications between the two groups except for pleural effusion (p = 0.040). S. epidermidis was the most frequently isolated pathogen in both groups. Conclusion: We did not find a study which compares scrub + alcohol + iodine and povidone iodine in our literature review. We think that our study is original in this respect. We can conclude that skin disinfection with scrub + alcohol + iodine was superior to using only povidone iodine in terms of the pathogens isolated afterwards from the wound.Item Analysis of right ventricle function with strain imaging before and after pulmonary valve replacement(2016) Gursu, Hazim Alper; Varan, Birgul; Sade, Elif; Erdogan, Ilkay; Ozkan, Murat; 26779972Background: Pulmonary valve insufficiency may develop after surgical treatment of tetralogy of Fallot (ToF). Severe pulmonary valve insufficiency may result in right ventricular dysfunction. We aimed to compare cardiac magnetic resonance (CMR), with echocardiography. Methods: Patients who developed severe pulmonary valve insufficiency after total correction for ToF, were included in the study. CMR was used to measure end-diastolic, end-systolic volumes and ejection fraction of the right ventricle before and 6 months after replacement, and echocardiographic strain imaging was obtained before, and 1, 3, and 6 months after replacement. Results: There were significant differences between pre- and post-replacement QRS durations, and right ventricle end-diastolic and end-systolic volumes measured with CMR (p < 0.05). However, right ventricular ejection fraction (RVEF) did not change. Therefore, CMR determined that right ventricle size and volume increased, and right ventricular function deteriorated before replacement. After replacement, no significant improvement was seen in RVEF. Lower-than-normal right ventricle strain and strain rate before replacement indicated that healthy and dysfunctional myocardium could be differentiated by this method. Pre-replacement strain and strain rate of asymptomatic and symptomatic patients were similar. Strain and strain rate values increased 6 months after replacement (p < 0.05). Conclusions: We suppose that increased experience with strain imaging, and further studies on a larger patient group with a longer follow-up period would show that this method is quite advantageous, and it will take its place in the literature as a non-invasive technique that may be used instead of magnetic resonance.
