Abstract: Objective  To explore the application value of in-bed bicycle exercise in early postoperative rehabilitation of patients with severe acute pancreatitis.Methods A retrospective analysis of 161 patients with severe acute pancreatitis admitted to the ICU of the Xijing Hospital,Affiliated Air Force Medical University from January 2016 to December 2020.A total of 89 cases were divided into the observation group(in-bed bicycle exercise) and 72 cases in the control group(traditional in-bed exercise).Record the implementation rate of exercise,inflammation indicators,defecation time,muscle strength classification of both lower limbs,ECOG score,first time to get out of bed,abdominal distension score,deep vein catheterization displacement,abdominal drainage tube dislodged and other adverse events.Results There was no statistical difference in the implementation rate of exercise within 72 h between the two groups(P>0.05).Two groups had no statistical difference in deep vein catheterization displacement,abdominal drainage tube dislodged(P>0.05).The observation group’s abdominal distension score,defecation time,and the first time to get out of bed were significantly earlier than the control group(P<0.05).The muscle strength of both lower limbs and ECOG scores were significantly higher than those of the control group at 1 week after surgery(P<0.05) and inflammation indicators decreased.Conclusion Patients with severe acute pancreatitis have better compliance with in-bed bicycle exercise in the early postoperative period,without increasing the incidence of postoperative adverse events.It is worthy of clinical promotion while promoting the rehabilitation of patients without increasing the burden of nursing.
