Abstract Background Use of capnography as a non-invasive method during the weaning process for fast track extubation (FTE) is controversial. We conducted the present study to determine whether pulse oximetry and capnography could be utilized as alternatives to arterial blood gas (ABG) measurements in patients under mechanical ventilation (MV) following coronary artery bypass graft (CABG) surgery. Methods In this randomized clinical trial, 70 patients, who were candidates for CABG surgery, were randomly assigned into two equal groups (n = 35); the intervention group and the control group. In the intervention group, the ventilator management and weaning from MV was done using Etco2 from capnography and SpO2 from pulse oximetry. Meanwhile, in the control group, weaning was done based on ABG analysis. The length of intensive care unit (ICU) stay, time to extubation, number of manual ventilator setting changes, and alarms were compared between the groups. Results The end-tidal carbon dioxide (ETCO2) levels in the intervention group were completely similar to the partial pressure of carbon dioxide (PaCo2) in the control group (39.5 ± 3.1 vs. 39.4 ± 4.32, P > 0.05). The mean extubation times were significantly shorter in the intervention group compared to those in the control patients (212.2 ± 80.6 vs. 342.7 ± 110.7, P < 0.001). Moreover, the number of changes in the manual ventilator setting and the number of alarms were lower in the intervention group (P < 0.05). However, the differences in the length of stay in ICU between the two groups were not significant (P = 0.219). Conclusion According to our results, the use of non-invasive monitors, including capnography and pulse oximetry, is emphasized in order to utilize FTE after CABG surgery. Furthermore, it is a safe and valuable monitor that could be a good alternative for ABG in this population. Nevertheless, further studies with larger sample sizes and on different disease states and populations are required to assess the accuracy of our findings.

The Mean

Background. Moderate-to-severe pain is reported in up to 75% of the patients in the first 48 hours after cardiac surgery. Evidence suggests that distraction is an effective nursing intervention for controlling short-term and transient pain. Distraction can be achieved by various techniques, including progressive muscle relaxation, meditation, and rhythmic breathing (RB). The present research aimed at evaluating the impacts of RB on the severity of sternotomy pain after Coronary Artery Bypass Graft (CABG). Methods. This randomized, controlled clinical trial was conducted on 60 patients after CABG surgery at the open-heart surgery Intensive Care Unit (ICU) of Kowsar Hospital, affiliated to Semnan University of Medical Sciences in Semnan, Iran. The patients were selected through convenience sampling and randomly assigned to two groups, including (1) intervention or RB and (2) control groups. RB was performed in the intervention group every 12 hours (9 a.m. and 9 p.m.) for three consecutive days after the surgery. The control group received only routine care for pain control (opioid analgesics) with no additional interventions. The severity of pain was measured every day in both groups of patients before and after the interventions using the Visual Analog Scale (VAS). Results. The mean postintervention pain scores were significantly different from the mean preintervention scores in the intervention group ( p  < 0.05). The changes in the mean pain score in the intervention group were also significantly different from the corresponding changes in the controls ( p  < 0.05). Conclusion. Based on the results, the severity of pain after the intervention was significantly lower in the RB group compared to the control. RB was found to be an effective technique for reducing the patients’ pain and is therefore recommended as a post-CABG pain control technique.

Background Controlling risk factors and lifestyle modification in coronary artery bypass graft (CABG) patients plays an important role and leads to the empowerment of these patients to take care of themselves. One way to empower these patients is to improve their self-efficacy and hope. This study aimed to investigate the effect of the planned discharge on cardiac self-efficacy and hope of CABG patients. Methods In this quasi-experimental study, the sample consisted of 60 people (30 in the intervention group and 30 in the control group). Data were collected using the Miller Hope Questionnaire and Sullivan Cardiac Self-Efficacy Questionnaire. Data analysis was performed using central indices of mean and standard deviation and Chi-square, t-tests and one-way analysis of variance. The software used for data analysis was SPSS version 19. Results The mean age of participants in the control group was 91/9 ± 86/91 and in the intervention, group was 33/7 ± 7/58. There was no significant difference between the demographic characteristics, heart self-efficacy and hope scores of the participants in the control and intervention groups. After the intervention, there was a meaningful statistical difference between the two groups at discharge time and 1 month afterward in both hope and cardiac heart self-efficacy scores ( p = 0.001, 0.0001). Conclusion In this study, the implementation of the discharge program was effective in increasing the hope and cardiac self-efficacy of CABG patients and the use of the discharge plan is recommended to improve the outcomes of these patients.

Background: Atrial Fibrillation (AF) is a common complication following Coronary artery bypass graft (CABG) Surgery, which may be due to oxidative stress, necrosis and inflammation during CABG and can lead to increases the length of hospital stay and the risk of morbidity and mortality. Melatonin is a hormone with anti-oxidant and anti-inflammatory properties in the cardiovascular system. This study assessed the efficacy of sublingual consumption of melatonin in reducing necrosis and inflammation, in patients undergoing CABG with respect to C-reactive protein (hs-CRP), Creatine KinaseMuscle-Brain subunits (CK-MB) and cardiac Troponin T (cTnT) levels. Methods: One hundred and two patients were enrolled and twenty-six patients were excluded during the study process and finally seventy-six patients undergoing CABG surgery randomly assigned to melatonin group (n = 38, 12 mg sublingual melatonin the evening before and 1 hour before surgery, or the control group which did not receive Melatonin, n = 38). Three patients in the melatonin group and three patients in the control group were excluded from the study because of discontinued intervention and lost to follow up. The samples were collected before and 24 hours after surgery. hs-CRP, CKMB, and cTnT levels were measured in all patients with the Elisa method. Results: There was no significant difference in influencing variables among the groups at the baseline. The incidence of AF following CABG surgery was not statistically significant between the two groups, (p value = 0.71). However, the duration of AF (p value = 0.01), the levels of hs-CRP (p value = 0.001) and CK-MB (p value = 0.004) measured, 24 hours after surgery were significantly lower in the melatonin group. cTnT levels measured 24 hours post-CABG did not show any significant difference in both groups (p value = 0.52). Conclusion: Our findings suggest that the administration of melatonin may help modulate oxidative stress, based on the reduction of the levels of hs-CRP, CK-MB, and the duration of AF following CABG surgery.

Coronary artery bypass graft (CABG) surgery effectively relieves symptoms and improves outcomes. However, patients undergoing CABG surgery typically have advanced coronary atherosclerotic disease and remain at high risk for symptom recurrence and adverse events. Functional non-invasive testing for ischaemia is commonly used as a gatekeeper for invasive coronary and graft angiography, and for guiding subsequent revascularisation decisions. However, performing and interpreting non-invasive ischaemia testing in patients post CABG is challenging, irrespective of the imaging modality used. Multiple factors including advanced multi-vessel native vessel disease, variability in coronary hemodynamics post-surgery, differences in graft lengths and vasomotor properties, and complex myocardial scar morphology are only some of the pathophysiological mechanisms that complicate ischaemia evaluation in this patient population. Systematic assessment of the impact of these challenges in relation to each imaging modality may help optimize diagnostic test selection by incorporating clinical information and individual patient characteristics. At the same time, recent technological advances in cardiac imaging including improvements in image quality, wider availability of quantitative techniques for measuring myocardial blood flow and the introduction of artificial intelligence-based approaches for image analysis offer the opportunity to re-evaluate the value of ischaemia testing, providing new insights into the pathophysiological processes that determine outcomes in this patient population.

Platelet Aggregability

Abstract Background Dual antiplatelet therapy is recommended for patients (pts) with acute coronary syndromes (ACS). However, 10–15% of pts have indication of coronary artery bypass graft (CABG) for the index event and current guidelines recommend stopping clopidogrel at least 5 days prior to CABG. This waiting time could increase hospital length of stay, thus having negative impacts on costs and clinical complications. Purpose To evaluate if release to CABG based on platelet aggregability by Multiplate AnalyzerTM would be non-inferior in comparison with common practice (5 days) in terms of 24-hours post-CABG bleeding. Methods The PLAT-CABG (NCT 02516267) is a randomized, open label, non-inferiority trial (boundary 25%) testing a strategy of platelet aggregability-guided release to CABG versus standard-of-care on the primary endpoint of chest tube drainage in the first 24 hours post CABG. A total of 190 pts admitted with ACS, treated with aspirin + clopidogrel and with indication for CABG, were assigned to clopidogrel discontinued 5 days prior to CABG (control group) vs. daily measurements of platelet aggregability to ADP using Multiplate AnalyzerTM (intervention group) with CABG occurring after recovering from platelet inhibition (pre-defined as a threshold of 46 AU). Results The main results are depicted in the table Main results of PLAT-CABG study Variables Control Group (n=95) Intervention Group (n=95) P-value for superiority P-value for non-inferiority Chest tube drainage (mL), Median (25th–75th) 350 (250–500) 350 (250–500) 0.680 0.001 Time symptom to CABG (hours), Median (25th–75th) 191 (150–281) 166 (119–225) <0.001 NA Time surgery indication to CABG (hours), Median (25th–75th) 136 (112–161) 112 (66–142) <0.001 NA CABG = coronary artery bypass graft. Conclusion Platelet-aggregability guided release to CABG is non-inferior to standard of care in ACS patients awaiting CABG in terms of peri-operative bleeding and significantly shortens the time to CABG.

Objectives: To evaluate the effect of discharge information calendar on healthy lifestyle behaviors (HLB) of patients who underwent coronary artery bypass graft (CABG) surgery. Patients and Methods: This randomized controlled study was carried out on 68 patients (study group=33; control group=35) who underwent CABG surgery between 10.11.2017-10.10.2018. Data were collected from the patient information form and HLB Scale-II. The patients were visited by the researcher one day before their discharge and verbal information was given about the HLB. Discharge information calendar that is designed as a desktop calendar and includes 14 main headings on HLB was used to inform the patients in the study group. HLB of the patients were evaluated at the day before discharge, 2nd and 6th weeks following discharge. Results: The mean scale scores obtained from the 2nd and 6th weeks of the study group were significantly higher compared with the control group (p<0.001). Conclusion: The information provided using discharge information calendar to the patients after CABG surgery are effective in gaining HLB for the patients. It is recommended to use visual and written materials (such as the discharging information calendar) to inform patients and help patients to remember the information during the post-discharge period.

Background: Atrial fibrillation is one of the most frequent complications and a major risk of morbidity and mortality after cardiac surgery. Antioxidants such as vitamin C are used for prevention of this arrhythmia. Different results of studies have been reported, but most of them have shown efficiency of vitamin C in prophylaxis of postoperative AF. We tried to examine this efficacy with larger sample size. Methods: Three hundred and fourteen on pump coronary artery bypass graft surgery alone. Patients were divided into two groups: The intervention group received vitamin C (N = 160) and the control group did not receive any (N = 154). Intervention group was administered two grams of vitamin C intravenously (IV) 24 hours preoperatively, 500 mg every 12 hours IV for 48 hours in ICU, and 500 mg every 12 hours PO for 48 hours in ward. Continuous monitoring in ICU and three times a day ECG was used for AF detection. The two groups were compared. Results: The two groups were matched in terms of age, sex, LA size, ejection fraction, functional class, and TSH level. Of the patients, 244 were male. Mean age was 62 years (40-84 years) in both groups. M/F ratio was four in both groups. Functional class and ejection fraction were the same in both groups. There was no mean TSH level difference. AF occurrence in vitamin C group was 7.6 % and in control group was 7.8 %. There was no difference in ICU or hospital stay. Conclusions: Prophylactic use of vitamin C does not further reduce postoperative atrial fibrillation in on pump CABG patients.

Introduction: Coronary artery disease (CAD) is one of the major causes of mortality all over the world. In this relation, coronary artery bypass grafting (CABG) is one of the most important treatments for CAD patients. However, it leads to a lot of stress in the patient. The aim of this study was to use the Neuman model to moderate the stressors in patients undergoing coronary artery bypass graft. Methods: This study was a randomized clinical trial of two groups performed on patients admitted to the coronary artery bypass graft; and the study completed with 64 patients. The intervention was performed by the researcher according to the format of the Neuman Model, which included the investigation of the stressors, and the determination of the goals and strategies for the actions. Intrapersonal, interpersonal, and extra personal factors were evaluated using a Revised Cardiac Surgery Stressor Scale (RCSSS). The intervention program was designed by the researcher based on prevention levels using scientific resources. The collected data were analyzed in SPSS ver. 13 using descriptive and inferential statistics. Results: Before the intervention, the mean score of the stressors was not significantly different between the two groups. But immediately after the intervention and before discharging the intervention group, it was significantly less than the control group. Conclusion: Using a Neuman-based program as an effective and low-cost intervention can moderate the stressors and reduce the stress of patients awaiting coronary artery bypass graft. This theory can be a good guide to offering the roles needed to provide health services in the community.

SummaryPatients undergoing surgery for coronary artery bypass graft or heart valve replacement had their platelet count and mean volume measured pre-operatively, immediately post-operatively and serially for up to 48 days after the surgical procedure. The mean pre-operative platelet count of 1.95 ± 0.11 × 1011/1 (n = 26) fell significantly to 1.35 ± 0.09 × 1011/1 immediately post-operatively (p <0.001) (n = 22), without a significant alteration in the mean platelet volume. The average platelet count rose to a maximum of 5.07 ± 0.66 × 1011/1 between days 14 and 17 after surgery while the average mean platelet volume fell from preparative and post-operative values of 7.25 ± 0.14 and 7.20 ± 0.14 fl respectively to a minimum of 6.16 ± 0.16 fl by day 20. Seven patients were followed for 32 days or longer after the operation. By this time they had achieved steady state thrombopoiesis and their average platelet count was 2.44 ± 0.33 × 1011/1, significantly higher than the pre-operative value (p <0.05), while their average mean platelet volume was 6.63 ± 0.21 fl, significantly lower than before surgery (p <0.001). The pre-operative values for the platelet volume and counts of these patients were significantly different from a control group of 32 young males, while the chronic post-operative values were not. These long term changes in platelet volume and count may reflect changes in the thrombopoietic control system secondary to the corrective surgery.
