11th EORNA Congress Valencia, Spain | 16 - 18 May 2024 ePosters 48 204 THE EFFECT OF PREOPERATIVE COLD APPLICATION ON POSTOPERATIVE PAIN, BLEEDING, AND FUNCTIONAL STATUS IN TOTAL KNEE REPLACEMENT SURGERY Merve Özsoy Durmaz1 1, Ayfer Özbaş2 1Istanbul Medipol University, Nursing, 2T.C. Demiroğlu Bilim Üniversitesi Florence Nightingale Hospital School of Nursing, Turkey Background: It has been determined that there is a gap in the literature on how starting cold application in the preoperative period affects pain, edema, and functional status in the postoperative period. Objectives: This study was performed as a prospective, experimental, and randomized controlled design in order to determine the effect of local cold application started in the preoperative period for patients who will undergo unilateral total knee prosthesis on the patient’s pain, bleeding, and functional status in the postoperative period. Methods: The study was conducted with 60 patients who were randomized into experimental (n=30) and control (n=30) groups. In the experimental group, the knee of the patients to be treated with surgery was applied cold with a gel ice pack 2 times 20 minutes at 30-minute intervals in the morning of surgery. The patients in the control group were not treated with any cold in the preoperative period. In the early postoperative period (3 days), the pain, bleeding, edema, and functional status of the patients were monitored. Results: While there was a statistically significant difference between the groups of patients in terms of pain, amount of drainage, amount of edema on the first day, and physical function(p<0.05), there was no significant difference in terms of HGB and HTC values, amount of edema on the second and third days (p>0.05). Conclusion: It was seen that cold application was effective in pain management in the preoperative period, in reducing the amount of bleeding from the amount of drain in the early period, in reducing the edema in the knee area, and in improving the functional status. In the preoperative period, cold application is recommended to be applied in patients who do not have any contraindications to cold. 229 Postoperative skin disinfection with chlorhexidine: Evaluating bacterial growth after shoulder arthroplasty surgery Ida Markström1 1, Kristofer Bjerså2, Gunilla Hollman-Frisman1, Margareta Bachrach Lindström1, Karin Falk- Brynhildsen3 1Linköping university, Department of Health, Medicine and Caring sciences, 2Sahlgrenska Academy, Department of Surgery, Clinical Sciences, Gothenburg, Sweden, 3Örebro University, Faculty of Medicine and Health. School of Health Sciences, Örebro, Sweden Background: Surgical site infections (SSIs) pose a significant risk to patient well-being, resulting in increased morbidity, mortality, and financial burden on society. Effective infection prevention measures during surgical procedures are of utmost importance. The primary source of causative microorganisms for SSIs is the patient’s own skin flora. Therefore, proper skin preparation before surgery is crucial in reducing bacterial colonization at the surgical site. Chlorhexidine in ethanol is commonly used for skin disinfection and has a sustained effect in inhibiting bacterial growth. The human skin takes 48 hours to naturally develop its own defense mechanisms against bacterial colonization, raising the question of whether postoperative disinfection with chlorhexidine can impact bacterial colonization during the initial 48 hours following surgery. Objectives: The main objective of this study was to evaluate postoperative bacterial growth on the skin 48 hours after shoulder arthroplasty surgery, using a 5 mg/ml chlorhexidine in ethanol solution prior to dressing application. Methods: A single-blind, controlled, block-randomized intervention study was conducted at a county hospital in southeast Sweden from 2019 to 2023. A total of 60 patients were included in the study. Results: At the time of submission, no analyses have been conducted; however, they will be completed in time for the conference in May 2024. Conclusion: Refer to the above information.
