Valencia, Spain | 16 - 18 May 2024 11th EORNA Congress ePoster Guided View 37 and Visual Analogue Scale (VAS) were used as data collection tools. Unlike the control group, patients in the experimental group received foot massage 4 times after surgery. Patients in the experimental and control groups were evaluated in terms of pain and sleep quality on postoperative days 0th, 1st and 2nd. Hospitalization times of both groups were compared for early discharge. The results were evaluated with a 95% confidence interval and a significance level of p<0.05. Results: The Visual Analogue Scale scores of the patients in the experimental group who received foot massage were statistically significantly lower and reported less pain on the 0th, 1st and 2nd postoperative day compared to the control group (p<0.05). Patients in the experimental group who received foot massage had higher RCSQ scores on postoperative days 1 and 2 than those in the control group and reported sleeping well on both days. The hospital stay of patients in the experimental group was shorter than the control group (p<0.05, p=0,001). Conclusion: Patients who received foot massage after spine surgery experienced less pain, earlier mobilization and discharge, and improved sleep quality. 350 Surgical positioning injuries following lateral positioning Charlotte Holck Larsen1, Elnaz Parweai1 1Herlev Hospital, OR, Herlev, Denmark Background: Careful and correct surgical positioning is important in order to prevent positioning injuries. Objectives: The objective of this study was to investigate the number of patients who experienced postsurgical positioning injuries caused by lateral positioning for urological procedures. Methods: We prospectively included 82 patients who in December2022- October 2023 underwent a urological procedure in lateral position. The ipsilateral arm was positioned on an armboard in level with the shoulder with a slight flexion of the elbow. The lower extremities were secured and the table flexed, whereby the kidney space was opened and slightly rotated posteriorly to the side of the procedure. The study was approved by Region Hovedstaden (P-2022-322). Baseline and operative data were recorded. Postoperative positioning injuries were assessed with interview by OR-nurses at the first postoperative day, after 3 and 5 weeks. Descriptive statistics were used and associations between preoperative and operative factors and postsurgical positioning injuries assessed with logistic regression. Results: Twenty-nine(35%) patients were female with a median age of 62 years(IQR52-72) and a median BMI of 26 (IQR24-32). Two patients (2%) underwent an open procedure, 29 (35%) patients underwent conventional laparoscopic procedure and 51 (62%) underwent a robotic assisted laparoscopic procedure. The median duration in lateral positioning was 150 min. (IQR120-183). Post-surgery 32 (39%) patients experienced injuries that was attributed to the positioning. At five weeks 13 (16%).Patients reported a range of injuries with pain and numbness the most common. There were no correlation between the side of the procedure and the side or type of the injury. There were no preoperative or postoperative variables associated with the risk of having injuries 5 weeks following the procedure. Conclusion: Surgical positioning injuries following urological procedures in lateral positioning is nonnegligible and likely underreported. 370 Development and validation of a risk prediction model for inadvertent intraoperative hypothermia in patients undergoing off-pump cardio hybrid operation based on decision tree and nomogram Hailei Bian1, LI Ni2 1Shanghai East Hospital, Tongji University, operation room, Shanghai, China, 2Shanghai East Hospital, Tongji University, Nursing Department, Shanghai, China Background: Intraoperative hypothermia is one of the most serious complications of patients undergoing off-pump cardiac hybrid operation. However, there is a lack of risk prediction models for them which helps nurses to identify high-risk patients as early as possible and take targeted preventing measures.The nomogram and CART decision tree model are model construction methods based on machine learning. This study used two methods to build intraoperative hypothermia risk prediction model for patients undergoing off-pump cardiac hybrid operation, and conducted internal verification of the model.
