    The comparison between the effects of aspirin and clopidogrel monotherapy on postoperative bleeding in diabetic patients after off-pump coronary artery bypass surgery
    (Imr Press, 2021) Altinay, Levent; Cetin, Erdem
    There is limited data about the bleeding complication of antiplatelet therapy after coronary artery bypass graft (CABG) operations focused on diabetic patients. Herein, we aimed to evaluate the effects of aspirin and clopidogrel monotherapies on postoperative bleeding in these patients. A total of 165 diabetic patients who underwent isolated off-pump beating heart coronary artery bypass (OPCAB) operation were evaluated, 84 patients were included in this retrospective study. Patients were divided into groups according to the type of antiplatelet regime. Chest tube drainage amounts and the amount of blood product transfusions were evaluated. Acetylsalicylic acid (ASA) - group included 42 aspirin monotherapy and Clopidogrel group included 42 clopidogrel monotherapy patients after propensity matching. The mean drainage amount in ASA - group was 670.24 +/- 185.46 mL, in Clopidogrel - group was 921.43 +/- 167.53 mL (p < 0.001). More packed red blood cell (PRBC) and fresh frozen plasma (FFP) units were needed in the Clopidogrel - group than in the ASA group (2.05 +/- 1.13 vs. 0.83 +/- 0.93 units of PRBC, and 1.90 +/- 0.58 vs. 1.05 +/- 0.58 units of FFP, respectively, p< 0.001). In conclusion, clopidogrel had a stronger effect on bleeding in diabetic patients than aspirin after OPCAB surgery.

    The effectiveness of short text messages on nurses' arrhythmia interpretation skills
    (Wiley, 2023) Kes, Duygu; Ozduran, Bahar; Celik, Sevim; Cetin, Erdem
    Background Intensive care nurses play an important role in the management of critically ill patients including identification of cardiac arrhythmias. Interventions to improve arrhythmia identification can be expensive, time-consuming, and are not always successful. Aims This study aimed to explore the effectiveness of using short message service (SMS) messaging to improve intensive care nurses' cardiac arrhythmia interpretation skills. Design This study was a prospective, two-group, assessor-blinded, randomized controlled trial with a pretest-posttest experimental design. Methods The study was conducted from February 2020 to February 2021 for the intervention as well as the control group, in a teaching hospital in northwest Turkey. The intervention group was sent the one-way SMS messages on cardiac arrhythmias via WhatsApp during an 8-week period, whereas the control group did not receive any intervention. The Cardiac arrhythmias assessment questionnaire (CAAQ) was used to measure outcomes. The data were analysed using ANCOVA and an independent t-test. Results A total of 66 intensive care nurses were randomly assigned to either the intervention or the control group. The ANCOVA analysis indicated that ICU nurses who received SMS messages about cardiac arrhythmias two times a week had significantly increased CAAQ scores (P < 0.001) with a large effect size (partial eta-squared = 0.588). Conclusion This study concluded that using SMS messages as a training tool has a positive influence on cardiac arrhythmias interpretation skills among ICU nurses. Relevance to clinical practice Using SMS messages could be an alternative, effective, and innovative approach to improve nurses' clinical practice skills.

    Effects of cardiopulmonary bypass on pulmonary function in COPD patients undergoing beating heart coronary artery bypass surgery
    (Clinics Cardive Publ Pty Ltd, 2019) Cetin, Erdem; Altinay, Levent
    Background: The aim of this study was to compare the effects of cardiopulmonaty bypass (CPB) on the postoperative course of patients with chronic obstructive pulmonary disease (COPD) following coronary artery bypass graft (CABG) surgery. Methods: This retrospective study included 375 COPD patients who underwent isolated CABG surgery with either on-pump (group 1) or off-pump beating heart techniques (group 2) between April 2014 and August 2018. Results: Group 1 included 42 (11.2%) and group 2 included 333 (88.8%) patients. The mean mechanical ventilatorysupport times of groups 1 and 2 were 10.6 +/- 36.2 and 5.1 +/- 2.61 hours, respectively (p = 0.561). The mortality rates of groups 1 and 2 were 4.76% (two patients) and 1.50% (five patients), respectively (p = 0.142). Conclusion: The on-pump heating heart CABG surgery did not affect the postoperative mechanical ventilatory support times in patients with COPD.
