ABSTRACT
The optimal time to ambulation remains unclear for intensive care unit (ICU) patients following abdominal surgery. While previous studies have explored various mobilization techniques, a direct comparison between ambulation and other early mobilization methods is lacking. Additionally, the impact of time to ambulation on complications and disuse syndrome prevention requires further investigation. This study aimed to identify the optimal time to ambulation for ICU patients after abdominal surgery and considered its potential influence on complications and disuse syndrome. We examined the relationship between time to ambulation and hospital length of stay (LOS). Patients were categorized into the nondelayed (discharge within the protocol time) and delayed (discharge later than expected) groups. Data regarding preoperative functioning, postoperative complications, and time to discharge were retrospectively collected and analyzed. Of the 274 postsurgical patients managed in the ICU at our hospital between 2018 and 2020, 188 were included. Time to ambulation was a significant prognostic factor for both groups, even after adjusting for operative time and complications. The area under the curve was 0.72, and the cutoff value for time to ambulation was 22 h (sensitivity, 68%; specificity, 77%). A correlation between time to ambulation and complications was observed, with both impacting the hospital LOS (model 1: p < 0.01, r = 0.22; model 2: p < 0.01, r = 0.29). Specific cutoff values for time to ambulation will contribute to better surgical protocols.
ABSTRACT
PURPOSE: To clarify the factors affecting the length of hospitalization after laparoscopic gastrectomy based on the physical function, body composition, and postoperative course of the patients. METHODS: Of the patients with gastric cancer who underwent laparoscopic resection at the Ageo Central General Hospital, Japan, during 2018-2019, 51 underwent physical therapy. Data regarding the objective variables, such as length of postoperative hospital stay, and baseline attributes, such as age, body weight, body mass index (BMI), and corrected limb muscle mass, postoperative course (operation time, the estimated blood loss, the day before walking independently), preoperative physical function (grip strength, 6-min walking distance), and preoperative respiratory function (vital capacity [VC]%, one-second rate) were collected retrospectively from the medical records and analyzed using multiple regression plots. RESULTS: The most suitable hospital day model after surgery is one that incorporates the total postoperative course, respiratory function, physical function (R2 = 0.45, p < 0001), and operation time (ß = 0.12, p < 0.06). The information of the day before independent walking (ß = 0.68, p < 0.001) and % VC (ß = -0.19, p < 0.04) was extracted as factors. CONCLUSION: We concluded that the operation time, walking independence days, and % VC influence the postoperative length of hospital days.
