ERAS Maintenance Protocol The basic philosophy of the ERAS Protocol is to reduce metabolic stress due to surgical trauma, and to return to normal activity as soon as possible by supporting the normalization of functions in a short time. ERAS protocols are a protocol consisting of a total of 24 items covering the perioperative period of a patient, which starts in the outpatient clinic in the preoperative period and ends at home with discharge. includes applications. Elements of this preparation and treatment method, which is different from the traditional, were applied to our patients in this group before (11), during the operation (6) and after the operation (7). In the study, the data were collected with the personal introduction form introducing the characteristics of the patients, the Rhodes Nausea-Vomiting and Regurgitation Index (WPI), the Mcgill Pain Scale and the Postoperative Evaluation Form created within the scope of the ERAS Care Protocol.

ItThe group that underwent surgery with the traditional method is the control group. The surgical procedure preparation procedure in the institution where the study was conducted was not exceeded.

The data in the control group were collected with the patient information form, the Postoperative Evaluation Form to evaluate the symptoms after the surgical intervention, the McGill Pain Scale Short Form, the Rhodes Nausea-Vomiting Regurgitation Index.

It covers the period before, during and after the surgery.

In the sample calculation of the research; To measure the significant differences between independent groups, a minimum of 128 samples is required (64 for each group) in order to determine 80% statistical power and α = 0.05 significance and d = 0.50 effect size in the t-test to be performed.

In order to evaluate the effect of the post-operative accelerated recovery (ERAS) protocol on the patient recovery process, 128 patients who applied to the hospital for bariatric surgery between April and June 2022 were included in the study. 64 patients were divided into groups as the ERAS Protocol group and 64 patients as the control group.

Postoperative pain status was evaluated with the McGill Pain Questionnaire (SF-MPQ). In determining the severity of pain, the McGill Pain Scale Numerical Evaluation was evaluated as 0-10 points, 0 no pain, 10 unbearable pain. A score of 4 or less for patients meant less pain.

Postoperative nausea, vomiting and retching were evaluated with the "Rhodes Nausea-Vomiting Rectal Index". According to the sub-dimensions of the scale, each of the symptoms of nausea, vomiting and retching was scored in the range of 0-12 points. 0 meant the least distress - 12 meant the most distress.
