Background : Active respiratory therapy like incentive spirometer is needed to prevent pulmonary complications for patients undergoing post-operative under general anesthesia. But in many cases, patients don't practicing it for their pain, or they just forget doing it. And medical staffs are having difficulties in checking how well the patients follow the directions for doing incentive spirometer. Insufficient practicing incentive spirometer and deep breathing cause delay their health recovery.~Therefore, we want to make some tools which can encourage the patients' practicing for incentive spirometer and also supply the objective achievement of patients to medical staffs.~Objective : This study evaluates the effectiveness of the mobile self-input tool providing alarm and visual motivation, how much more it can encourage practicing of incentive spirometer undergoing post-operative patients under general anesthesia.~Design: RCT (randomized controlled trial)~Setting: In the Department of Gastrointestinal Surgery at the Samsung Medical Center~Enrollment : 44 patients undergoing gastrectomy.~Intervention 6-1) For study group : participants on study group are received self-input tool with alarm system on tablet.~Alarm is provided only if insufficient practice (less than 10 times/hour) from 9am to 9pm. The practicing rate is sent to Nurse's Dashboard.~6-2) For control group : participants on control group are received self-input tool without alarm on tablet. Their practicing rate is not sent to Nurse's Dashboard.~Scoring by practicing incentive spirometer from 9 am to 9 pm. (Only when a subject practiced more than 10 times per hour, the subject get 10 points) (Full score 240)~Study period : for 48hrs from one day to 3rd day after patient's operation~Satisfaction survey (SUS) after study(3rd day after operation)
This study evaluates the effectiveness of the mobile self-input tool providing alarm and visual motivation, how much more it can encourage practicing of incentive spirometer undergoing post-operative patients under general anesthesia. Half of participants will receive the mobile self-input tool providing alarm, and their practicing rate will be sent to Nurse's Dashboard. While the other half will receive the mobile self-input tool, but it won't contain alarm function and their practicing rate won't be sent to Nurse's Dashboard, either.
