Abstract:

[Abstract] Objective To explore the influence of uncertainty in illness in compliance of respiratory function exer? cise and rehabilitation after surgery in patients with coronary artery bypass graft (CABG) surgery.Methods Mishel uncer? tainty in illness scale and compliance of respiratory function exercise scale were used to collect data in 108patients with CABG. The correlation of the uncertainty in illness and compliance of respiratory function exercise was analyzed. Patients were divided into three groups (high score, medium score and low score groups) according to the detection of uncertainty in illness. Values of compliance of respiratory function exercise, postoperative care time, postoperative ventilation time, postop? erative hospital stay duration,6-min walking test (6MWD) and left ventricular ejection fraction (LVEF) were compared be? tween three groups. Results The uncertainty in illness was in medium level (95.51±9.48) in patients with CABG surgery, which was negatively correlated with compliance of respiratory function exercise (r=-0.926, P<0.01). The postoperative venti? lation time and postoperative care time were less in low score group than those of medium score group and high score group. The compliance of respiratory function exercise,6-min walking test and postoperative LVEF were better in low score group than those of medium score group and high score group. Conclusion Medical personnel should take targeted interventions to reduce the uncertainty in illness in patients, enhance the compliance of respiratory function exercise, reduce the postopera? tive complications and promote early recovery of patients.
