Postoperative mobilization and rehabilitation is vital to a patient's recovery, but inadequate pain control can impede patients' progress. Diaphragmatic breathing is an additional non-pharmacological and non-invasive tool with no adverse effects that could aid in recovery. This will serve as a pilot study for a possible larger controlled trials.",[65],"Anesthesia and Analgesia","2024-08-25",{"date":68,"type":69},"2024-08-27","ACTUAL",{"date":71,"type":69},"2024-06-10",{"date":73,"type":61},"2024-10-01",{"name":5,"class":6},1]
