Objectives: This study will be conducted to determine the effect of early mobilization on postoperative recovery in abdominal surgery patients..

Methods: This research is a randomized controlled experimental study. In the Gastrointestinal Surgery Department, a total of 130 patients will be included, consisting of 65 experimental group and 65 control group, who are scheduled for abdominal surgery in the study. In the study, data will be collected using a survey form, Numerical Rating Scale, gradual mobilization chart in the first 24 hours after surgery, and Postoperative Recovery Index (PoRI-TR). On the day before the surgery, the experimental group will receive early mobilization training. On the day of the surgery, vital signs, oxygen saturation, and pain intensity will be assessed before the first mobilization. Pain control will be ensured before mobilization. Each mobilization will be carried out in accordance with the gradual mobilization schedule within the first 24 hours after surgery. Following the Enhanced Recovery After Surgery (ERAS) protocol recommendation, mobilization will be provided outside of bed for a total of 2 hours, with durations increasing by the hour on the day of surgery under the supervision of the researcher: 5, 15, 25, 35, and 40 minutes. Mobilizations for patients showing signs of orthostatic hypotension will be postponed by 30 minutes. On the days following the surgery, patients will be informed to spend 6 hours outside of bed. The control group will receive routine care procedures. The second part of the questionnaire will be administered on the day of the surgery for both the experimental and control groups, and the PoRI-TR will be applied at the 25th hour after surgery. Data will be collected through face-to-face interviews within 20-25 minutes. The data obtained from the research will be evaluated using the SPSS 22.00 program. The normality of the data will be determined by Skewness-Kurtosis tests. Based on this result, either parametric or non-parametric tests will be applied.
