Introduction: Mitral valve disease is a common heart condition that may require mitral valve replacement (MVR) surgery. One of the potential complications after MVR is the development of atrial fibrillation (AF). Left atrial volume index (LAVI) is a measure of left atrial size that has been linked to the development of AF in patients with mitral valve disease. The present study aimed to observe the post-operative support needed by patients after MVR surgery, particularly those with elevated LAVI and the incidence of post-operative AF. Methods: This prospective observational study was conducted at the Department of Cardiac Surgery, National institute of cardiovascular diseases (NICVD), Sher-e-Bangla Nagar, Dhaka, Bangladesh. The study duration was 1 year, from Mar, 2018 to Feb, 2019. During this period, a total of 60 patients who underwent Mitral Valve Replacement (MVR) for mitral valve diseases at the study hospital were included in the study following the inclusion and exclusion criteria through a purposive sampling method. The 60 patients were divided in two equal groups, Group A, consisting of 30 Patients who had Left Atrial Volume Index of ≥ 39 ml/m2 after operation, while group B had been comprised of 30 patients who had Left Atrial Volume Index of < 39 ml/m2 after operation. Result: Around 23.33% of participants in both groups were aged 21-30, while 40% of Group A and 36.66% of Group B were aged 31-40. In terms of BMI, 53.33% of Group A and 46.66% of Group B had a normal BMI, while 40% and 43.33% were overweight, and 6.66% and 10% were obese, respectively. Specifically, 23.33% of participants in Group A developed post-operative AF, while only 6.66% of participants in Group B developed it. The p-value for this comparison was 0.015. The results demonstrate that Group B had significantly smaller LA diameter, LA volume, LAVI, LVIDS, and LV ejection fraction compared to Group A at all three measurements post-operation (p<0.05). However, there was no significant ...
Introduction: Arterial catheters are widely used in intensive care units for continuous blood pressure monitoring and blood sampling. The patency of these lines is maintained by continuous flushing, usually with the addition of the anticoagulant heparin to the flushing solution. Normal saline solution can maintain patency of arterial and central venous pressure monitoring catheters. Aim of the Study: The aim of this study was to evaluate the effect between normal saline and heparin solution in arterial line flushing on platelet count. Methods: This was a prospective cross- sectional study conducted in the Department of Cardiac surgery of National Institute of Cardiovascular Disease (NICVD), Sher-E-Bangla Nagar, Dhaka, Bangladesh during the period from July 2016 to June 2017. This study included sixty patients who underwent single valve replacement surgery and shifted to the ICU with arterial line catheter. The patients who fulfilled the inclusion criteria were divided into two groups- Group A (with heparin solution) and Group B (with normal saline). Result: In total 60 patients from both the groups completed the study. In our study we found the mean ± SD of age among group A & B was (36.3±6.7) & (35.7±10.3) respectively. We found the mean± SD of platelet count at 1st POD was (206530±64441) & (212543±48768); at 3rd POD was (226517±60185) & (245957±52826); at 7th POD was (240517±57379) & (257713±53655); at 14th POD was (245850±52680) & (244337±56796) in Group A & B respectively. Conclusion: In our study we didn’t find any statistically significant difference regarding the patients’ demographic characteristics and there were no statistically significant difference of platelet counts between Group A and Group B at preoperative period, post pump, 1st POD, 2nd POD, 3rd POD, 4th POD, 7th POD and 14th POD.
