To implement the best care strategies, assessment about the postoperative prognostic, like the length of stay in an intensive care unit (ICU), is very important to the perioperative professionals’ team. In this context, this research was developed to understand the influence of Obesity (Body Mass Index >=30) in the postoperative period of patients undergoing cardiac surgery and aim to determine the association between preoperative obesity and length of stay in heart surgery patients. This study is a retrospective observational study. The patient cohort was performed by adults (>18 years), had elective cardiac surgery, and information about BMI status. Regression unadjusted and adjusted analysis was performed to determine the association between preoperative obesity and postoperative length of stay in ICU. 1146 eligible patients were analysed and cardiac surgery included coronary artery bypass graft (CABG), valve surgery, or combined CABG and valve surgery in 532 (46%), 494 (43%), and 120 (10%) patients, respectively. Differences between groups with and without Obesity were stratified by age, gender, primary diagnosis, BMI, Diabetes, type of surgery, and presence of any postoperative complications. In a regression analysis we found that did not have any increase in ICU days that would be predicted by the presence of Obesity (0.33) and adjusted analysis with confounders some variables that may be associated with predicting the outcome, as Postoperative complications and Bleeding (p < 0.001). These results can be explained by a phenomenon known as the “obesity paradox” and can subside new studies about preoperative nutritional therapies to benefit surgical patients’ postoperative recovery. In this study, preoperative obesity is not associated with a major length of stay in an ICU in patients undergoing heart surgery. eP02 Patients’ experiences regarding severe leg wound infection associated with coronary artery bypass grafting: a qualitative study H. Larsson1,2, M. Hälleberg-Nyman1, K. Falk-Brynhildsen1 1Örebro University, Faculty of Medicine and Health, Örebro, Sweden, 2Örebro University Hospital, Department of Vascular and Cardiothoracic Surgery, Örebro, Sweden Objectives: The aim of this study was to describe patients’ experiences associated with acquiring a severe infection in the harvesting site after coronary artery bypass grafting (CABG). Methods: This study was conducted at the department of vascular and cardiothoracic surgery in a Swedish university hospital. Patients diagnosed with a severe surgical site infection in the harvesting site following CABG were included. Sixteen face-to-face interviews were conducted from May to December 2018 and analysed with inductive content analysis. Results: Varying impact of body and mind was the main category and illustrated the patients’ experiences of severe wound infection in the harvesting site after CABG. Two generic categories were identified: physical impact and thoughts about the complication. The experience of pain in the wound varied greatly between the participants, from no pain at all in several of the patients to severe pain in others. Several of the participants said it led to increased fear and anxiety, with thoughts and reflections regarding why the infection had occurred or whether there would be even more difficult complications in their recovery, while others were affected only slightly or not at all. For most of the participants, everyday life was affected to varying degrees due to the complication in the harvesting site. Conclusions: The findings in this study indicate the complications as an important issue with varying impact for the patients. However, most of the participants were satisfied with the outcome after the wound had healed. Patients should be advised to seek care at an early stage if symptoms of infection occur. Improved individual pain management is needed for those with severe pain, and varied experiences imply a need for person-centred care.
